Core A7 switched from AVX back to SSE2
Posted: Sat Oct 12, 2019 2:50 am
I noticed sse2 mentioned in the startup of the most recent a7 work unit on a machine that supports AVX. I searched through the logs folder and the client switched from using AVX to SSE2 between July 1st and 2nd. Were there assignment or work server code changes that would have affected CPU detection and instructed the client to use SSE2? Anyone that is currently running a7 work units, could you check your logs to see what SIMD method is in use and indicate whether your CPU supports AVX, AVX2, or AVX-512?
Log entries for work unit startups are below.
Last A7 work unit using AVX version of Core_a7 version 0.0.17:
Next A7 work unit using SSE2 version of Core_a7 version 0.0.17:
Most recent A7 work unit using SSE2 version of Core_a7 version 0.0.17:
