Intel Updates C++ and Fortran Compilers

Libraries now included with compiler purchase

By Alex Handy

June 15, 2007 — (Page 1 of 2)
Intel has decided that it’s time to refresh the packaging of its compilers. The company released version 10 of its C++ and Fortran compilers in early June, and for the first time it has decided to bundle some of its libraries with the compilers.

In another first for the company, all of the compilers in the lineup are 64-bit-capable, ahead of the release of Mac OS X 10.5, and as a bonus, Intel’s Fortran compiler now includes a free copy of Microsoft’s Visual Studio 2005.

The bundled libraries include support for a variety of modern development concerns, such as building video codecs and dealing with multithreaded applications. James Reinders, director of marketing for Intel software developer products division, said that the compiler team at Intel tried to insert as many optimizations as possible into the code to save developers time and energy.

Those optimizations ended up being a boon for the Intel developers as well. Reinders claimed that, in their efforts to bring vectorization and loop parallelization capabilities into the compiler, the team inadvertently made the product faster, simpler and more stable.

“We came up with this breakthrough optimizer design. You want the compiler to be able to automatically take advantage of [multimedia instruction sets such as] SSE3 or the forthcoming SSE4, or MMX. That’s all built into our compiler, with vectorization. You can automatically create a program that runs off and takes advantage of multicore,” said Reinders of the compiler’s new abilities.

“Anything the compiler can do [to optimize a program] is very useful,” Reinders added. We thought this would solve some problems, but it worked a little better than we expected. It’s given us a good performance boost; it ended up simplifying our design in a way. It’s faster and more reliable. Our compiler is able to examine a program and not only find ways to exploit SSE3 and SSE4 really well, but it’s able to create additional threads for the program, and able to do them together and optimize it correctly. It not only speeds up C++ and Fortran, but it made our libraries faster as well.”
