Illegal instruction
Alexey Kozlov
it seems like you're trying to run AVX2 version of RAxML on a node which does not support AVX2 instructions.
So please either use a different node (Haswell/Skylake) or run raxmlHPC-PTHREADS-AVX / raxmlHPC-PTHREADS-SSE3 instead.
Also please note that you have very few patterns in your alignments (161), and hence should use maybe 2 or 4 threads but
definitely not 60 (it would only make it slower).
Best,
Alexey
