Intel ISPC is a compiler for a C-based SPMD (single program, multiple data) language that targets SIMD vector units on CPUs and GPUs. It lets programmers write serial-looking code that compiles to wide-vector instructions, delivering significant speedups without hand-written intrinsics.
Use cases
- compile C-like SPMD code to SIMD instructions
- speed up numeric kernels on AVX/SSE vector units
- write high-performance code without intrinsics
- parallelize computation across cores and vector lanes
- target GPUs with a C-based language
When to choose
- you need SIMD performance but want to avoid assembly or intrinsics
- your workload is data-parallel and benefits from vectorization
- you want portable high-performance kernels across CPU architectures
When to avoid
- your code is inherently serial or branch-heavy
- you need a general-purpose language rather than a performance kernel compiler
- your target hardware lacks SIMD vector units
