Hi, We are using ISPC 1.13.0, we have trouble updating ISPC because we compile on old MacOS (see https://github.com/ispc/ispc/issues/1737 ). Is ISPC 1.14.1 really needed ? What feature of 1.14.1 is needed (and not available in previous version) ? Regards, Colin Chargy

Hi Colin, Yes, ISPC 1.13.0 is required because it has a critical bug in handling AVX-512 support. ISPC 1.14.1 is the oldest version that has the fix. Regards, Attila
