Trying to build OpenBLAS 0.2.20 on SGI UV 300 running SLES 12 SP2 and running into problems, hope somebody may have a clue as to what's going on. TL;DR: tests segfault when using more than one thread.
First run, without BIGNUMA=1 results in the following:
- OPENBLAS_NUM_THREADS=1 OMP_NUM_THREADS=1 with sblat1, dblat1, cblat1, zblat1 tests succeed
- OPENBLAS_NUM_THREADS=2 ./sblat1 fails with
OpenBLAS Warning : The number of CPU/Cores(432) is beyond the limit(256). Terminated.
Following this error, next build is executed with 'BIGNUMA=1 make', this results in the following:
- OPENBLAS_NUM_THREADS=1 OMP_NUM_THREADS=1 with sblat1, dblat1, cblat1, zblat1 tests succeed
2)OPENBLAS_NUM_THREADS=2 ./sblat1
Makefile:8: recipe for target 'level1' failed
make[1]: *** [level1] Segmentation fault (core dumped)
make[1]: *** Waiting for unfinished jobs....
At this point trying to execute any of the tests (sblat1/dblat1/cblat1/zblat1) with either no OPENBLAS/OMP env variables set, or by setting them to use more than one thread results in segmentation fault. Example strace is available at https://gist.github.com/dominikborkowski/c44b554ab94e5e6dd336d174ee25e1c0
Earlier versions of OpenBLAS compile just fine. Has anybody else run into this problem?
Thanks!
