BMC Software 1990s

1 In 1999, BMC acquired the Israeli firm New Dimension Software (flagship product CONTROL-

M), which made application service as well as management software, for $673 million cash. New Dimension Software's products handled

such tasks as security administration, document management and multi-platform job scheduling.

In 2000, BMC bought "an Israeli maker of enterprise application management software for

mainframe computer system", named Optisystems, for $70 million.


CA Technologies 2000s

1 Following CA's acquisition of Uccel in 1987, many of CA's customers felt

trapped, considering the company's dominance in mainframe security software, tape management and

batch job scheduling

job scheduling / workload automation product, ESP, by acquiring

Information Technology Infrastructure Library - ICT operations management

1 Operations, however should primarily work from documented processes and procedures and should be concerned

with a number of specific sub-processes, such as: output management, job

scheduling, backup and restore, network monitoring/management, system

monitoring/management, database monitoring/management storage

Supercomputer - Operating systems

1 While in a traditional multi-user computer system job scheduling is in effect a tasking

problem for processing and peripheral resources, in a massively parallel system,

the job management system needs to manage the allocation of both

computational and communication resources, as well as gracefully dealing with

inevitable hardware failures when tens of thousands of processors are present.

Rank reversals in decision making

1 With other computational methods, for instance with a job scheduling method, one can examine a set of

different answers and then categorize the answers according to

some metric of performance (for instance, a project's completion time)


Single-system image

1 but a single image may be presented for more limited purposes, just job scheduling

for instance, which may be achieved by means of an additional layer of software

over conventional Operating system|operating system images running on each Node (networking)|node. The interest in SSI clusters is based on the perception that they may be simpler to use and

administer than more specialized clusters.


TomTom - History

1 TomTom Business Solutions is the business-to-business division of TomTom and has been operating since 2005. This arm of TomTom specialises in telematics;

providing vehicle tracking, navigation, two-way communications, job scheduling

and report-logging capabilities to organisations. In 2010, it announced it

was providing its service to over 125,000 vehicles operating in Europe.

original version of Computer Associates' job scheduling product,

CA-SCHEDULER 7.0, which was written from scratch by CA and

released in 1985 for the OS/MVS, DOS/VSE and VM/CMS Operating

Systems.https://store.theartofservice.com/the-job-scheduling-toolkit.html

background program execution (commonly called batch processing).[http://www.cs.huji.ac.il/~feit/parsche

Job scheduler

1 Job scheduling should not be confused with Scheduling

(computing)|process scheduling, which is the assignment of currently

running processes to CPUs by the operating system.


Job scheduler - Overview

1 If software from a completely different area includes all or some of

those features, this software is considered to have job scheduling

capabilities.


Job scheduler - Overview

1 Web hosting services provide job scheduling capabilities through a Control panel (computer)|control

panel or a webcron|webcron solution


Job scheduler - Main concepts

1 Beyond the basic, single OS instance scheduling tools there are two major

architectures that exist for Job Scheduling software.


Job scheduler - Main concepts

1 * Master/Agent architecture — the historic architecture for Job

Scheduling software. The Job Scheduling software is installed on a

single machine (Master), while on production machines only a very

small component (Agent) is installed that awaits commands from the

Master, executes them, then returns the exit code back to the Master.


Job scheduler - History

1 Job Scheduling has a long history. Job Schedulers have been one of the

major components of IT infrastructure since the early

mainframe systems. At first, stacks of punched cards were processed

one after the other, hence the term “batch processing.”


Job scheduler - History

1 # Service Oriented job scheduling - recent developments in Service

Oriented Architecture (SOA) have seen a move towards deploying job

scheduling as a reusable IT infrastructure service that can play a

role in the integration of existing business application workload with new Web Services based real-time

applications.https://store.theartofservice.com/the-job-scheduling-toolkit.html

Platform Computing

1 'Platform Computing' was a privately held software company primarily

known for its job scheduling product, Load Sharing Facility (LSF). It was

founded in 1992 in Toronto, Ontario, Canada and headquartered in

Markham, Ontario with 11 branch offices across the United States,

Europe and Asia.[http://www.platform.com/comp

Computer Associates Int. Inc. v. Altai Inc. - Background of the case

1 Computer Associates (CA) created a Job scheduler|job scheduling program

called CA-SCHEDULER which sorts, runs, and controls the various tasks

given to a computer


Uccel

1 Uccel's big-ticket item claim to fame was software called UCC-1/TMS (Tape

Management System), an IBM mainframe product for managing the tape library in an OS/MVS operating system environment. In

1980, they developed their second big hitter and most profitable product, UCC-7 (job scheduler). The UCC-1, UCC-7, UCC-11

(batch job rerun/restart add-on) suite led the market for tape management and job

scheduling.https://store.theartofservice.com/the-job-scheduling-toolkit.html

Uccel

1 In 1986, UCCEL Corporation purchased Cambridge Systems Group, Inc., which marketed

for SKK, Inc. and their market-leading ACF2 mainframe security product. In June '87, Uccel was unexpectedly bought out by its archrival, Computer Associates, which aggressively sold directly competing products CA-Dynam/TLMS

(tape management), CA-Scheduler and batch job scheduling products originally from Capex

Corporation and Value Software, plus CA-Top Secret (security / mainframe discretionary access

control).


ASG Software Solutions

1 ASG’s products are used for cloud computing, business service management,

JES2

1 JES3 Main Device Setup (MDS) has more control over data sets shared

between systems than JES2, and JES3 Dependent Job Control (DJC) has

more provisions for scheduling jobs with dependencies on each other

than JES2. With the widespread use of sophisticated job scheduling software, DJC has become less

important.https://store.theartofservice.com/the-job-scheduling-toolkit.html

JES2

1 HASP was developed by IBM Federal Systems Division contractors at the Johnson Space Center in Houston. It originally managed job scheduling and print and punch output for a

single OS/360 computer, such as a single 360/65. Multi Access Spool

capability was added for to let peer computers share a common job queue and print/punch output

queues.https://store.theartofservice.com/the-job-scheduling-toolkit.html

JES2 - JES3

1 Using ASP made it possible to avoid the cost of the byte multiplexor channel, and offloading the job

scheduling, print, and card handling also offloaded those functions from

the larger machines.

Blocks (TBB) library for parallel programming.


Maximum independent set - Independent sets in interval intersection graphs

1 The problem of finding maximum independent sets in interval graphs

has been studied, for example, in the context of job scheduling: given a set of jobs that has to be executed on a

computer, find a maximum set of jobs that can be executed without

interfering with each other

Portable Batch System

1 'Portable Batch System' (or simply 'PBS') is the name of

computer software that performs job scheduler|job scheduling. Its primary

task is to allocate computational tasks, i.e., batch jobs, among the

available computing resources. It is often used in conjunction with UNIX

computer cluster|cluster environments.
