Truly Invisible Multitasking TechnologyPreface: This report is a general overviewof technologies, intended to provide a bet-ter understanding of certain limitationsinherent in modern operating systems. It isnot intended as the presentation of a sci-entific study. Note, for sake of brevity andbearing, descriptions of operating systemdesign and behavior, while wholly accurate,are presented in simplified form.

OverviewMultitasking is a method for sharing sys-tem resources so that multipleprocesses1 can appear to run simulta-neously. An example would be the abilityto run both a word editor and a spread-sheet application at the same time.

However, a component in a general pur-pose computer, such as the CPU, canonly execute one task at a given time.

Multitasking presents the illusion thatall execution is occurring simultane-ously by implementation of a thread2

scheduling system. It is in essence vir-tualization of the CPU, designed to foolapplications into believing they own theCPU exclusively. More powerful andfaster CPUs can execute larger tasks orexecute more in a given span of time.

Multiprocessing extends the principlesof multitasking to multiple CPUs, actu-ally allowing threads to run simultane-ously, where multitasking only feignsthis behavior. Multiprocessing, likemultitasking, is still limited in process-ing capacity to one action at a time ona given CPU.

For the purposes of this paper, multi-tasking will be used to refer to the

operating system’s thread handling.

Inside Multitasking:There are a variety of Multitasking tech-niques in use in operating systemstoday. Modern computer systems suchas Windows, Linux®, UNIX® and MacOS® X use a form of multitasking calledpreemptive multitasking with varyingunique differences. Preemptive multi-tasking is a more effective mechanismto guarantee resource sharing as it dif-ferentiates processes (e.g., I/O orCPU) and integrates I/O waiting so asto not delay processes that do notneed I/O device responses (such asdata returned from a hard drive).

emptive scheduling, while not a pureform, is more advanced, when com-pared to earlier MS-DOS®-based ver-sions of Windows, in that it better sep-arates processes by the resourcesthey use (e.g., CPU intensive vs. I/Obound). Of key importance is that italso allows processes to be prioritized.Prioritization involves implementing asystem by which one process, and itsassociated threads, can be deemed tobe more, equally, or less importantthan another process. An essentially“round-robin” scheduling system thenassigns resource time-slices availableto the active processes.

However, the prioritization value sys-tem is relatively rote in that it relies onthe process to generally define howimportant it is. It also applies anumeric value system (values of 0–31)in which a higher number indicatesgreater importance. A process with avalue of 8 will receive greater resourceaccess than a process with a priorityvalue of 4, but less than a processrunning at a priority of 13.

Processes that share a number value(e.g., word editor and spreadsheetthat both have a value of 8) are con-sidered equal, and must essentially“split” resources equally.

Ideal resource-sharing systems wouldknow more about unrelated processesthat share a priority value, and be ableto further subdivide resources. Then,based on actual needs at a given time,they could more effectively shareresources, rather than relying on a rel-atively rote hard-coded priority value.Windows NT preemptive multitaskingdoes not provide this.

Preemptive multitasking does provide avery basic implementation of dynamicresource assignment in order to ensurebetter system resource disseminationbetween high- and low-priority pro-cesses. The NT threadschedulingmechanism can dynamically adjust(increase or decrease) a priority valuefor a given process relative to itsassigned base priority and to its I/O-CPU burst3 characteristics (i.e., a CPU-bound process versus an I/O-boundprocess) to afford eventual access toresources. The justification for prioritychanges is simply dependent uponwhether a process is being starvedresource time due to an influx of high-priority processes. In these cases, thescheduler can dynamically reduce thepriority of processes and increase theright to access resources for others.

The phenomenon related to this occur-

rence is that the scheduler will actuallyprovide a lower-priority I/O-boundprocess a larger time slice than it nor-mally would if it hadn’t been starved.While the use of interrupts4 allows theblocking of I/O-bound processes, it’simportant to note that a process willnot be starved for more than 3–4 sec-onds. With processors operating in thegigahertz, a few seconds is retrospec-tively eons, but it will occur.

As one can see this system is benefi-cial to ensure that all processes getaccess to resources and that allprocesses are ordered in at least somesimple form of relative importance.

However, some shortcomings can beuncovered with this design. It can beshown that some applications active ona system, that are allocated resourcesevery 3–4 seconds, can and should bestarved resources until no other processrequires them. And, as suggested, prior-itization amongst seemingly “equal”applications is relatively rote.

It becomes obviously inadequate whentrue low-priority applications that canwait indefinitely (or near-indefinitely)for resource allocation, are force-fedresources.

InvisiTasking: “True BackgroundProcessing—Delivered”InvisiTasking is new technologydesigned to enhance multitasking andaddress some of the shortcomingsrelated to the lack of “enough infor-mation.” Having more informationallows better sharing of resources.InvisiTasking is specifically designedto address the “background” applica-tion to ensure it truly does run in thebackground and does not interferewith higher-priority processes such astransaction processing5, print queuingand quite frankly, anything else otherthan wasteful system idle time.

Unlike multitasking, which is inte-grated in the operating system’s ker-nel, InvisiTasking currently works inuser-mode. This means it will notpresently solve all the issues inherentin the core of multitasking for a back-ground application, but it will mitigatethe inherent shortcomings to the pointthey are no longer issues. It, ofcourse, requires an application to bewritten to leverage this technology.

Inside InvisiTasking:As CPU and I/O resources are almostnever fully utilized, InvisiTasking’s trans-parency is achieved by undetectablytapping into these unused systemresources. Software engineers some-times attempt to share resources bychoosing lower CPU priorities to rununder, and past efforts have beenmade at throttling disk and networkI/O. However, the goal of truly transpar-ent software has never before beenachieved until now.

To accomplish true transparency, oneneeds to be able to monitor CPU, mem-ory and the more significant hardwarebottlenecks of the disk drive and net-work. InvisiTasking takes a pro-activeapproach to instantly detect resourceusage while maintaining complete gran-ular control over its own activity, ensuringthat it never preempts users or services.

The key, of course, is to prove thatInvisiTasking theory holds true inpractice…

Benchmarking InvisitaskingTo demonstrate the effectiveness ofInvisiTasking, a couple of differentbenchmarking tests were performed.

A 32-bit tool called DkCopy was writtenby Diskeeper Corporation to demon-strate the benefit of InvisiTasking.DkCopy is a simple, straightforwardfile copy tool that copies a file fromone location to another (standardmode). DkCopy in this standard modeis representative of typical businessapplications such as SQL, LotusNotes®, Microsoft® Office, etc.

To demonstrate the benefit ofInvisiTasking, the utility also includes aspecial qualifier to apply InvisiTaskingtechnology to its file copy operations.Applying this qualifier can turn DkCopyinto a true background application.

Two independent tests with slightly dif-ferent metrics were completed. Bothtests used the same platforms andenvironments.

InvisiTasking Test 1The purpose of Test 1 is to test howquickly, by measuring time-to-complete,the standard copy operations of DkCopycompleted when another process wasalso running. The ramification of execut-ing a second program concurrent withthe primary program should naturallyshow impact upon the first program.

In this case, that concurrent applica-tion was also DkCopy, implementingthe switch that enables InvisiTasking.Again, this test is designed to detectany impact that DkCopy might experi-ence when another program was run-ning concurrently.

DkCopy with InvisiTasking enabled rep-resents a background application,such as a maintenance process, forwhich the developer intends to preventany negative overhead that woulddegrade performance of typical busi-ness applications.

Test 1 Procedure:1. DkCopy is run using its normaloperations to copy a file [DkCopy.exe].This is to establish a baseline for thetime this tool will take to complete itsactions.a. Test 1A copying a 150MB fileb. Test 1B copying a 890MB filec. Text 1C copying a 6GB file

2. Two instances of DkCopy were runsimultaneously. One operating nor-mally [DkCopy.exe] and one using theInvisiTasking option [DkCopy.exe-I].a. Test 1A copying a 150MB fileb. Test 1B copying a 890MB filec. Text 1C copying a 6GB file

In the tests (stage 1 and 2), each ofthe DkCopy tests were run a total ofsix times for each of three differentfile sizes (150MB, 890MB, 6GB), withthe results recorded. The highest andlowest scores were discarded and theremaining four scores averaged6 andrepresented in the charts shown. Thesecond instance of DkCopy (withInvisiTasking enabled) was performedin such a way that ensured no I/Oconflict or caching issues would skewresults. The system was reset to anidentical state in between all testruns to ensure identical starting envi-ronments for comparative testing.

Test 1 Summary (See Test 1 graphs on this page.) Thegraphs represent the time the copytook to complete, so lower numbersindicate faster runtimes. Varying levelsof hardware were used, ranging fromIntel Pentium III 500 MHz processorsto Dual Athlon 64 2.4 GHz processors.

As the results show, InvisiTaskingincurred only minimal per formance

impact in half the cases, and actuallyslightly enhanced performance (exe-cution time) in the other half oftested cases.

InvisiTasking Test 2The purpose of Test 2 was to measurethe system performance via a third-party benchmarking tool. The well-known benchmarking software product,PCMark®, was selected to measure PCperformance, as it is reputable andnonproprietary. PCMark (PCMark05

Revision 1 Build 0) uses a scoring sys-tem, testing major system componentssuch as CPU, memory, hard disks, andgraphics, to rate performance.

Test 2 Procedure:As in Test 1, the system was reset toan identical state in between all testruns to ensure identical starting envi-ronments for comparative testing. Thesame system-states created in Test 1were used for Test 2.

1. PCMark05 was run on eachmachine to establish a baseline of per-formance running this tool alone.

2. PCMark05 was run simultaneouslywith (DkCopy-I) on each machine. Thistest will measure the impact on sys-tem performance (as measured byPCMark) that an InvisiTasking-enabledprocess will have.

The PCMark05 tests were run fourtimes on each machine, with theresults averaged and represented inthe chart below. As the numbers pre-sented are PCMark05 scores, higherscores are better.

Test 2 Summary(See graphs on p. 7 and this page)PCMark confirms that earlier execution-time tests hold true when evaluatingspecific system components. Not onlydid InvisiTasking not impede computerperformance, it actually enhanced it in4 out of 5 cases. Generally, the morepowerful the system, the more signifi-cant the net gain.

InvisiTasking ConclusionThe benchmarking tests demonstrateproof-of-concept for the InvisiTaskingtechnology. They show that an Invisi-

Tasking-enabled process does not inter-fere with other running applications.This was proved in Test 1 where thetime to complete for the DkCopy opera-tion was, principally, not impacted.

Test 2 established that system oper-ations are also wholly available toper form a wide variety of typicalactions, such as CPU processing,memory accesses and modifications,and hard drive access, all while anInvisiTasking-enabled application isfully active.

Diskeeper Corporation also docu-mented performance improvementsin unrelated services without any cor-responding slows in the rest of thesystem processes. While testing I/O-intensive processes with InvisiTaskingprototypes, Diskeeper Corporationconfirmed an exceptionally significantadded benefit affecting processesoutside of InvisiTasking’s sphere:InvisiTasking introduces an efficiencyinto the way resources are allocatedby the kernel.

From a system overhead perspective,InvisiTasking-enabled applications canessentially be said to “not exist”—they are truly invisible on a system.

Diskeeper 2007 represents a paradigm shift in the way youwill improve the performance and reliability of your com-puters. For over a decade, Diskeeper has led the way inWindows system defragmentation technology, butDiskeeper 2007 takes such a significant step forward thatparadigm shift is truly the most appropriate term todescribe it. Diskeeper 2007 becomes the future of file sys-tem performance enhancement, for an overall faster andbetter performing system period.

You may already be familiar with some Diskeeper features,but Diskeeper 2007 represents a major milestone in theprogression of Diskeeper development. New users will findDiskeeper to be easy to use, yet comprehensive in its capa-bilities. Experienced Diskeeper users will see majorchanges, yet still recognize familiar features, presented ina new, more streamlined way.

Automatic Defragmentation—on a whole new levelDiskeeper has made its reputation with the trademarkedphrase “Set It and Forget It,”® meaning that onceDiskeeper is installed, you can simply forget about it.Defragmentation was taken care of automatically and yourcomputer was kept at peak performance all the time.

However, times have changed. Disk drives have grown toexponentially large proportions. And, with the growth ofdisk drives has come an explosion in the size and numberof files stored on disk drives. With terabyte drives (a trillionbytes) now easily available and smaller drives selling forvery little money, you can store a LOT of stuff—practicallyanything. And file sizes are continuing to increase as well.

Documents with embedded graphics, large presentations,scanned images, digital photos, MP3 music files and evenwhole TV shows and movies are now residing on harddrives. The vast quantities of these and their inordinate

size present new challenges for computer performance andmake defragmentation more critical than ever.

As disks have grown bigger and files have grown larger andmore numerous, dynamic file system per formanceenhancement is required more and more often to maintaina computer’s peak performance. While it used to be suffi-cient to defragment once a week, it eventually became nec-essary to defragment daily. Today, even daily defragmenta-tion is not enough. An hour’s production activity can seri-ously degrade performance.

But scheduling a defragmenter to run every hour is scary toperformance-conscious System Administrators and com-puter users. Even with features in Diskeeper like I/O Smart™and selectable run priorities, they are reluctant to run adefragmenter in the middle of the workday.

The answer is our new InvisiTasking technology. InvisiTaskingwas coined from “invisible” and “multitasking,” and this amaz-ing technological breakthrough promises to change the waythe world operates and maintains their computer systems.

InvisiTasking uses a proprietary technique developed in theDiskeeper Corporation research lab that monitors resourceconsumption on a Windows computer system and injectsDiskeeper processing into the unused portions—and only intothe unused portions. InvisiTasking is so good that it is all butimpossible to even detect whether Diskeeper is running. Thatmeans Diskeeper can run all the time. It never needs to backoff or shut down to reduce overhead, since overhead isalready virtually nonexistent! This means no more need forscheduling; there is no reason to schedule defragmentation.In fact, scheduling defragmentation worsens performance bydelaying the improvement that defragmentation brings.Diskeeper with InvisiTasking means a computer performs atpeak all the time, around the clock, not just for a few minutesafter each scheduled defragmentation run.

Now, you may be skeptical at first and find it hard to believethat InvisiTasking has virtually no impact on system over-head. For this reason, you can schedule times whenDiskeeper is prevented from running at all. Eventually, we aresure you’ll be convinced, and this type of lock-out schedulingwill be forgotten. The scheduling era is over, and the era oftruly automatic, invisible defragmentation has begun.

Reliable DataProtection withUndelete Recover lost files Instantly!

Even “saved over” versionsof Microsoft® Office files!

How many users have called your Help Desk in a panicsaying they’ve lost or overwritten a critically importantfile? The Windows server recycle bin doesn’t protectfiles deleted by network clients. Restoring files frombackup takes forever, and may not get the latest versionof the file. And neither backup nor “snapshots” can helpif a user has saved over the version he or she needs.

Now there is a solution—new Undelete 5! Undelete 5replaces the recycle bin with a Recovery Bin that cap-tures and protects all deleted files, no matter how theywere deleted. Undelete works in real time, so it alwayshas the latest version of the file—and in the case ofMicrosoft Word®, Excel® and PowerPoint® files, it caneven recover earlier “saved-over” versions.

Best yet, recovering files with Undelete 5 is instant—allit takes is a few clicks of the mouse. Undelete 5 evengives you the option of letting users recover their ownfiles from server Recovery Bins!

• Undelete 5 Server Edition captures and protects deleted files on your servers.

• Undelete 5 Client allows network users torecover their deleted files from the server.

• Undelete 5 Professional Edition provideslocal file protection plus client functionality.

“We are very happy with the product and its extremeease of use. It’s true that I can generally get lost filesfrom my backup tapes, but using Undelete is muchfaster and easier. Undelete also lets me restore lostfiles that haven’t been backed up to tape, but wereeither modified incorrectly or deleted.”

and beyond “normal” defragmentation to speed up your fileaccess and creation times. Traditionally, a defragmenter likeDiskeeper could restore the performance of a computer tolike new condition. Diskeeper with I-FAAST, however, canimprove the computer’s performance to better than new!

I-FAAST improves file access and creation by an average10%–20%. (We’ve seen up to 80% improvement in our test labs!) This is the first industry implementation of “DiskPerformance Calibration,” the modern evolution of the out-dated and inconclusive disk-optimization strategies of the past.

When I-FAAST is enabled, Diskeeper runs specially engi-neered benchmarks on your disk volumes to learn their per-formance characteristics. Diskeeper then transparentlymonitors volumes for file access frequency on an ongoingbasis to determine which files are requested most often.Special analysis techniques prevent Diskeeper from being“fooled” by files that have been recently accessed.

Using newly developed technology, Diskeeper sequencesthe files to take best advantage of both the logical charac-teristics and physical characteristics of the volume. Thesequencing process is integrated with background defrag-mentation, so it’s virtually transparent to you.

I-FAAST intelligence allows Diskeeper to adapt to changingsituations—so if the demands on a given system change,Diskeeper automatically adjusts its behavior accordingly.

This feature is included in Diskeeper Server Enterprise,Diskeeper Server Standard and Diskeeper ProfessionalPremier editions.

Terabyte Volume Engine 2.0The Terabyte Volume Engine (TVE) available only in Diskeeper2007 EnterpriseServer is also integrated with InvisiTaskingtechnology for invisible defragmentation of huge volumeswith millions of files. Now known as TVE 2.0, it is the onlytechnology that can keep pace with high-end systems thatfragment at extraordinary rates. The standard automaticdefragmentation engine in Diskeeper 2007 Server, while fastand amazingly efficient, does not have the horsepower tokeep up with extreme environments; only TVE 2.0 can solvethis unique problem.

TVE 2.0 also has tremendous enhancements to free spaceconsolidation, a top wish-list item from customers. The freespace consolidation occurs in coordination with the high-speed real-time defragmentation and is the only unobtrusiveway ever designed to allow thorough free space consolida-tion on busy 24/7 servers. Assisted by the TVE 2.0,Diskeeper 2007 EnterpriseServer provides a quantum leapin file system performance enhancement on your largestsystems—automatically.

Seagate Product Marketing Manager talks about defrag on

Computer Outlook Radio Talk Show

I think defrag is an excellent tool for keeping your performance and the health of yourdrive up to par. So the larger these drives get, the more data people are storing onthem, and the more you store on them, you edit and save and pull it back up anotherday. It sort of gets spread out across the hard drive, so when you defrag you are pullingall of these files closer together. What this does is he doesn’t have to search over this750G drive to find pieces of a file, they’re all aligned, kept nice and clean in one area.”
