I have a package that contains nearly 500 f90 files. I noticed that in the makefile, it was using -ax (automatic dispatch ) up to AVX2. I added COMMON-AVX512 to the options. One thing I noticed was that compilation is now slower. It seemed to stop for 30 seconds when it hit one particular subroutine. But main problem was that after a few hundred files, it aborted with unexpected internal error. The offending file wasn't doing anything exotic, mostly a linear regression.
This is 2024.1 version of the compiler, pretty much the latest.
Has anybody else compiled for AVX512?
