Bug #2880

Updated by Mark Abraham 5 months ago

Intel Compiler 2019.0.117
ParaStationMPI 5.2.1-1
hwloc 1.11.11
mkl 2019.0.117
numactl 2.0.12
CMake 3.13.0

Cpu: Intel(R) Xeon(R) Gold 6148 CPU @ 2.40GHz

When one forces compilation with AVX256, everything works. But letting CMAKE autodiscover it points to avx512 (which is present on this cpu). This leads to the following error on tests:

<pre>
Program received signal SIGSEGV, Segmentation fault.
