Intel® Code Coverage Tool
Example of code coverage summary for a project. The workload applied in this
test exercised 34 of 143 blocks, representing 5 of 19 functions in 2 of 3 modules. In the file, SAMPLE.C, 4 of 5
functions were exercised
Clicking on SAMPLE.C produces a listing that highlights the code that
was exercised. In this example, the pink-highlighted code was
never exercised, the yellow was run but not exercised by any of the tests set up by the developer and
the beige was partially covered.

Intel® Test Prioritization Tool Helps guide and speed software testing,
– Helps produce better code more quickly– Helps improve programmer productivity
Example:– These 3 achieve 52.17% block and 50.00% function coverage– Test 3 alone covers 45.65% of basic blocks or 87.50% of total
block coverage from all tests– By adding Test 2, cumulative block coverage goes to 52.17%, or
100% of the total block coverage of Test 1, Test 2, and Test 3 – Eliminating Test 1 has no negative impact on block coverage
and saves time

Intel® VTune™ Performance Analyzer
VTune analyzer’s intimate knowledge of the processor enables it to provide extensive insights into how software utilizes CPU resources
Allows you to identify and locate performance bottlenecks in your code
– Collects and displays software performance data– Features that help you identify and address
performance issues: Sampling that uses non-intrusive technologies Call Graph that displays graphically the program’s
flow of control Analyzer that has detailed knowledge of the
processor’s microarchitecture Intel Tuning Assistant that suggests optimization
techniques for your Windows code
“The Intel VTune Performance Analyzer took a multi-day task and turned it into a sub-day task.”
—— Randy Camp, V.P. Software Research and Development, MUSICMATCH, Inc.
16Copyright © 2002, Intel Corporation. All rights reserved.*Other brands and names are the property of their respective owners www.intel.com/software/products
Sampling – Identifying Performance Bottlenecks
“Sample” the CPU’s execution context As program runs, gather occasional CPU context snapshots triggered by
CPU’s performance monitoring registers
– Interrupt based sampling using CPU registers
– Low intrusion – doesn’t change performance of the software
– No special builds required Sample rate set to provide statistically meaningful data
– Based on CPU clock speed or can be auto-calibrated Can measure performance sensitive CPU events
– Cache misses, branch mispredictions, etc.

How to use Intel VTune Performance Analyzer
Build the application– Build the application in Release mode with compiler optimizations
Find “Hotspots” using VTune– A “Hotspot” in an application or a system is a section of code where
there is a significant amount of activity.
– Finding “hotspots” would assist you in determining the compiler/ code
optimizations required for gaining performance improvement.
Symbols required for VTune Analyzer– Required Intel compiler switch (on Windows*): /Zi

Correctness Bugs: Data RacesThreading Overview: Challenges Unique to Threading
Thread1x = a + b
Thread2b = 42
What is value of x if:– Thread1 runs before Thread2?
– Thread2 runs before Thread1? Data race: concurrent read, modify, write of same
address
x = 3
x = 43
Suppose: a=1, b=2
Outcome depends on thread execution orderOutcome depends on thread execution order

Solving Data Races: Synchronization
Thread1Acquire(L)a = 1b = 2x = a + bRelease(L)
Acquisition of mutex L ensures atomic access– Only one thread can hold lock at a time
Example APIs:- EnterCriticalSection(), LeaveCriticalSection()- pthread_mutex_lock(), pthread_mutex_unlock()
Thread2Acquire(L)b = 42Release(L)
Threading Overview: Challenges Unique to Threading
29Copyright © 2002, Intel Corporation. All rights reserved.*Other brands and names are the property of their respective owners www.intel.com/software/products
Performance Penalty: Synchronization
Thread blocked waiting for Mutex– Thread not running, so no parallelism
Mutex Release, Acquire takes time– Release marks mutex free
– Acquire must check for free If free, mark as in use If not free, thread put to sleep
– Costs context switch out and in of processorCosts context switch out and in of processor

Why use Critical Path?
Goal is to shorten the execution time Shorten the critical path and you shorten
the total execution time Events recorded are events that impact the
critical path– Lock/Unlock
– Thread Creation, suspension, resume, termination
– Blocking calls, external events

Critical Path Analysis
System Utilization– Idle, serial, parallel and oversubscribed
– This is relative to the system the application is running on
Time categories along critical path (CP)– Cruise, overhead, blocking and impact time
