Chipmaker Intel has released the beta version of Intel Parallel Composer - the first component of the Intel Parallel Studio to reach beta. The other components of Intel Parallel Studio are Intel Parallel Advisor, Intel Parallel Inspector and Intel Parallel Amplifier. Intel Parallel Composer supports Threading Building Blocks (TBB), OpenMP and other standards.
Intel has launched the first public beta of a component of its Intel Parallel Studio - the Intel Parallel Composer.
Intel, which is as responsible as any other company for the push
toward parallelism with its creation of multicore processors, released
the Intel Parallel Composer to beta, while the other components of
Intel Parallel Studio -- Intel Parallel Advisor, Intel Parallel
Inspector and Intel Parallel Amplifier -- will be released to beta in
2009, said James Reinders, chief evangelist and director of marketing
for Intel's software development products.
Reinders said Intel Parallel Composer is a comprehensive set of
compilers and libraries for Microsoft Visual Studio C++ developers that
speeds and simplifies threading for improved productivity. It enhances
the capabilities of Microsoft Visual Studio to support the entire
spectrum of parallel expression and takes advantage of Intel's latest
versions of compilers and libraries for parallelism.
Intel Parallel Composer features both 32-bit and 64-bit compilers
and features support for standards such as Threading Building Blocks
(TBB) and OpenMP. OpenMP is an application programming interface (API)
that supports multiplatform shared memory multiprocessing programming
in C/C++ and Fortran.
"I tend to think of four things we provide to help developers adapt
to parallelism: Support for standards, debugger extensions, static
checking capabilities and extensions for parallelism," Reinders said.
Reinders said Intel supports OpenMP 3.0, the latest version of the
standard. "We have full support for it, which helps because the C
language was not written to support parallelism."
Intel also is supporting extensions to the C++ standard. "The
stewards of the C++ standard have been adding a variety of things to
the draft standard -- known as C++0x -- to support parallelism,"
Intel also is supporting lambda functions, parallel valarray and
asynchronous I/O, he said. The company is supporting asynchronous I/O
via support of the Portable Operating Systems Interface (POSIX)
specification. And auto-vectorization, auto-parallelization, spawn and
threaded libraries are among the additional features in Intel Parallel
In addition, Intel provides parallel debugger extensions that add
functionality to the Microsoft debugger, including a Parallel Lint
capability. Parallel Lint provides source file diagnostics to eliminate
bugs, boundary violations and memory corruptions.
