Illegal instruction (core dumped)

[dszyfelb]

I have the following issue:

/runme Config_amz.csv
new Network
new Layer
new Node array
Illegal instruction (core dumped)

I reversed to 2d10d46 and then I was able to run the experiment.

My TPH configuration:

hugeadm --pool-list

Please let me know if more information is needed

[xman]

You may try to remove the -mavx512f in the Makefile. Haswell doesn't support avx512f, hence it'll run into illegal opcode errors.

It helped. Thank you for your advice

@xman Thank you so much! @dszyfelb are you able to run the code? Can I close this issue?

[dszyfelb]

@keroro824 Yes I was. Please close the issue. Now I am looking for machine with avx512f support.
