Hi Freddie,

I met the same problem while running cases with openmp backend. I tried increasing the gimmik-max-nnz number but only works for smaller cases. I also tried to install libxsmm but still not working. Even running example case I have the very same problem without setting gimmik parameters which could work normally before. Any idea about what has happened? Thanks ahead!

Best wishes,  
Zhenyang
