Dear all,

I run the Yade program on a workstation, and the workstation configuration is Intel® Xeon(R) Gold 6130 CPU @ 2.10GHz × 64 with 64 cores and 128 threads. But when I run the program with Yadedaily -j128, the following problems occur:

BLAS: Program is Terminated. Because you tried to allocate too many memory regions.
Segmentation fault (core dumped)

I am running Yadedaily in Ubuntu 18.04 environment.I found that when I reduce the number of threads to 48 threads, the program can run normally.If I want to use all threads to run the program, what should I do?

Thanks in advance.
Jie
