Intel Security Bug “Downfall” AVX2/AVX512

Post by markuss »

Hi, had somebody updated his CPU-Microcode (Intel CPU´s 6th-11th CPU generation in general) because of the Downfall-security-bug?
The updated Microcode could decrease the speed for operations with AVX2/AVX512, which are very important for hpc-scientific calculation, if I am right. Some benchmarks beside FEM decrease up to 40-50% of performance...
Are there some Elmer-benchmarks? How do you deal with this problem?
Kindly regards, Markus
