What happens if you tell PETSc to build MUMPS instead of using Cray TPSL?
That is a simple way to rule out an issue with TPSL.
NERSC Edison has Intel Ivy Bridge, which supports AVX, which should be
fully supported in Valgrind 3.11, so I am rather confused why you see an
unrecognized instruction. Are you certain that you did not accidentally
use a binary compiled for Cori (which includes Haswell and Knights Landing)?
You can use Intel SDE (
https://software.intel.com/en-us/articles/intel-software-development-emulator)
and XED (https://github.com/intelxed/xed) to analyze and decode instruction
encodings to determine exactly what is unrecognized here.
