Intel SPMD Compiler Version 1.1 Released

December 7th, 2011

A major new release of the Intel SPMD Program Compiler (ispc) was posted on December 5, 2011. ispc is an extended version of the C programming language with support for “single program, multiple data” (SPMD) programming on the CPU; the SPMD model makes it easy to harness the full power of both the SIMD vector units and multiple cores on modern CPUs. The major features added in the 1.1 release include:

  • Full support for pointers, including pointer arithmetic, function pointers, and all other features of pointers in C.
  • A new parallel “foreach” statement, for more easily mapping computation to data.
  • Substantially revised documentation, including a new Performance Guide.
  • Many other small bug fixes and improvements.
