Intel engineers on Thursday released the newest version of the Intel Implicit SPMD Program Compiler, ISPC. The ISPC 1.31 supports their variant of the C programming language with extensions for Single Program, Multiple Data programming for leveraging their range of CPU and GPU hardware.

Intel ISPC 1.31 introduces new avx10.2nvl-x4, avx10.2nvl-x8, avx10.2nvl-x16, avx10.2nvl-x32, and avx10.2nvl-x64 targets that they have added for their upcoming Nova Lake processors. These new targets are similar to ISPC's existing Diamond Rapids target with AVX10.2 and APX but lacking AMX.

Interestingly, ISPC 1.31 also adds support for PowerPC 64-bit support in 2026... Besides no Intel-based PowerPC processors, it's surprising that only now they have added this support for IBM POWER8 and newer. This PowerPC 64-bit support is considered experimental and not enabled by default in the official ISPC builds.

ISPC 1.31 also brings various performance improvements, updates to the standard library, and bug fixing. See all the details about Intel's ISPC 1.31 compiler on GitHub.
