Package cpu

Extras

Intel

The INTEL_DISABLE_EXT environment variable can control which CPU extensions are available for the running process. It should be a comma-separate list of upper-case strings as follows

Flag	Description
ALL	Disable all CPU extensions and fall back to Go implementation
AVX2	Disable AVX2 optimizations
AVX	Disable AVX optimizations
SSE	Disable all SSE optimizations
SSE4	Disable SSE42, SSE41 optimizations
SSSE3	Disable supplemental SSE3 optimizations
SSE3	Disable SSE3 optimizations
SSE2	Disable SSE2 optimizations

Any unrecognized flags will be ignored and therefore it is possible to leave the environment variable with a bogus value such as NONE when experimenting.
