Overview
Intel® Threading Tools make it easier to create multithreaded applications
that take advantage of the performance benefits of Hyper-Threading Technology
included in Intel® Pentium and Intel® Xeon? processor-based computer systems.
Hyper-Threading Technology from Intel enables the processor to execute two
threads (parts of a software program) in parallel ? so your software can run
more efficiently.
Intel Threading Tools include Intel® Thread Checker, to locate threading
errors, and Thread Profiler to identify thread performance issues.
Intel Thread Checker automatically locates bugs in threaded software that
might otherwise go undetected. It eliminates this guesswork and pinpoints the
location of errors to help quickly analyze and correct them.
Intel Thread Checker graphical displays and groups errors by context for easy
review. It can identify six levels of threading issues, from errors and warnings
to informative comments. In addition, it classifies each issue it finds for easy
prioritization: errors, warnings, cautions, informational and remarks. Sort
errors by severity to focus on the most important issues first. Sorting by file
lets you focus on bugs you own. Once you find the bugs, easily drill down to the
root causes with several graphical tools.
Thread Profiler monitors your application?s execution to detect threading
performance issues, including thread overhead and synchronization impact. Thread
Profiler provides graphical displays to help analyze and correct threading
bottlenecks for Win32 or OpenMP threaded software.
Features and Benefits
- Automatic Error Detection saves time to create enough tests to
catch the common, uncommon, and intermittent threading bugs
- Detection of race conditions, thread deadlocks, and thread stalls
saves execution time by finding even subtle parallel programming issues
- Bug Isolation shows exactly which variables are causing the bug,
where variables get used by the threads, where variables are declared, and
the call stack to offending lines of code
- Compatibility with Win32 APIs for Threads, C runtime library
functions, and OpenMP ? Uses familiar Win32 API and C runtime library
function plus all OpenMP pragmas and clauses
- Choose any of several Microsoft compilers to build your software
for analysis
- Intel® Fortran and Intel® C++ Compilers ? Displays additional
details and the actual variable names, even when using pointers, if you
build your software with an Intel compiler and the /Qtcheck command-line
option
- Trial version is available
What?s New in the Intel Thread Checker 1.0 for Windows
- Integration with the Microsoft Visual Studio .NET means you can run
Intel Thread Checker and view results in the Microsoft Visual Studio .NET
development environment.
- With the choice of more compilers to build your software, you can select
the compiler to build your software for analysis: Intel® C++ Compiler, 7.0
or higher; Intel® Fortran Compiler 7.0 or higher; Microsoft Visual C++ .NET
2002, 2003 Editions; and Microsoft Visual C++, 6.0.
- Provides one-click help for diagnostics to show possible causes and
solution. When using the diagnostic view, just right click for diagnostic
help.
- Supports user-defined synchronization primitives, if you do not use
Win32 or OpenMP libraries.
- Now supports thread-count dependent OpenMP APIs and nested OpenMP
parallel regions.
Get Insight into Threading Glitches
Intel Thread Checker helps you find and fix threading errors in Win32 and
OpenMP threaded software, letting you tune your threaded software for better
performance.
Works Within Visual Studio
Use Intel Thread Checker within the Microsoft Visual Studio .NET development
environment. Thread Checker is compatible with the Win32 APIs for Threads, the C
runtime library functions, and OpenMP pragmas and clauses. It is integrated with
Intel® VTune? Performance Analyzer.
