Segmantation fault with latest libopenblas 0.3.10 #101

Closed bgruening closed 4 years ago

bgruening commented 4 years ago

Issue:

We got a coredump with the latest version 0.3.10 (build 2): https://travis-ci.com/github/lldelisle/pyGenomeTracks/jobs/362129644#L974

libopenblas-0.3.9 seems to work for us. Both versions (also 0.3.10-openmp_h709eae2_2) seems to cause the segfault.

ping @lldelisle and @isuruf

isuruf commented 4 years ago

Can you try setting the env variable OPENBLAS_CORETYPE=Nehalem ? Can you also run lscpu ?

bgruening commented 4 years ago

That worked!

isuruf commented 4 years ago

Can you send a PR to revert the kernel/ changes in https://github.com/xianyi/OpenBLAS/pull/2516 ?

bgruening commented 4 years ago

I can try to revert this PR. Should we pull our packages?

isuruf commented 4 years ago

I'd rather not. Pulling latest will result in segfaults for others

bgruening commented 4 years ago

I think the impact is rather big of this issue and its not clear how long it will take to fix it upstream. Reverting is not as easy. I will have time today in the evening to try again.

isuruf commented 4 years ago

@lldelisle, what do you get with lscpu?

Also, can you try building openblas master?

Also, can you try building openblas master?

Can you tell me how to do that?

lldelisle commented 4 years ago

git clone and make?

isuruf commented 4 years ago

Yes, git clone and make DYNAMIC_ARCH=1 BINARY=64 NO_LAPACK=0 TARGET=PRESCOTT NO_AFFINITY=1 USE_THREAD=1 NUM_THREADS=128 USE_OPENMP=0 and then make install PREFIX=$CONDA_PREFIX

lldelisle commented 4 years ago

Is this normal?

(testOpenBlas) [ldelisle@SV-49-002 OpenBLAS]$ make DYNAMIC_ARCH=1 BINARY=64 NO_LAPACK=0 TARGET=PREFIX NO_AFFINITY=1 USE_THREAD=1 NUM_THREADS=128 USE_OPENMP=0
getarch.c:1210:2: error: #error "The TARGET specified on the command line or in Makefile.rule is not supported. Please choose a target from TargetList.txt"
 1210 | #error "The TARGET specified on the command line or in Makefile.rule is not supported. Please choose a target from TargetList.txt"
      |  ^~~~~
make: *** [Makefile.prebuild:66: getarch] Error 1

Then it continues...

isuruf commented 4 years ago

Sorry, I made a mistake. Can you try, make DYNAMIC_ARCH=1 BINARY=64 NO_LAPACK=0 TARGET=PRESCOTT NO_AFFINITY=1 USE_THREAD=1 NUM_THREADS=128 USE_OPENMP=0 ?

lldelisle commented 4 years ago

No problem, it is running with the new command.
