All flavors of AVX, AMX, AES, VAES, SERIALIZE, ENQCMD, MOVDIRx, FMA, and BMI2 are among the instructions being reported on the web interface. Test profiles will begin displaying what notable CPU instructions are used by a given test/benchmark.
Plus with the forthcoming Advanced Matrix Extensions (AMX) among other more recent notable extensions, the feature makes more sense and usefulness these days.Īs of this weekend, the functionality is now restored on. These days it's more interesting as well in an AVX-512 era where it can have significant implications on per-core clock speeds. After last year's overhaul to, I began toying with it again and rewrote the implementation and is now much more capable. Now users can have an immediate idea if a given test is making use of certain performance-sensitive instructions or not.Ībout nine years ago I wrote an initial CPU instruction analysis for albeit was in rough shape and not of much priority. The latest is working to automatically evaluate what prominent CPU instructions are used by a given test profile.Īn example showing the new CPU instruction set usage reporting on a test profile pages.
For those wondering how say AVX heavy a particular program is being benchmarked or if a given program/benchmark supports making use of new instruction set extensions such as Vector AES or forthcoming AVX VNNI or AMX, the Phoronix Test Suite and can now provide that insight on a per-test basis with common CPU instruction set extensions.įollowing the re-architected roll-out from last year, new and exciting features continue to be enabled especially for its analytics engine and providing more insight around test profile (benchmark) capabilities.
