Intel(r) SPMD Program Compiler
|
|
==============================
|
|
|
|
Welcome to the Intel(r) SPMD Program Compiler (ispc)!
|
|
|
|
ispc is a new compiler for "single program, multiple data" (SPMD)
|
|
programs. Under the SPMD model, the programmer writes a program that mostly
|
|
appears to be a regular serial program, though the execution model is
|
|
actually that a number of program instances execute in parallel on the
|
|
hardware. ispc compiles a C-based SPMD programming language to run on the
|
|
SIMD units of CPUs; it frequently provides a a 3x or more speedup on CPUs
|
|
with 4-wide SSE units, without any of the difficulty of writing intrinsics
|
|
code.
|
|
|
|
ispc is an open source compiler under the BSD license; see the file
|
|
LICENSE.txt. ispc supports Windows, Mac, and Linux, with both x86 and
|
|
x86-64 targets. It currently supports the SSE2, SSE4, and AVX instruction
|
|
sets.
