Hello everyone, I am trying to solve linear system with sparse-direct solver on Kraken Cray XT5 system. As I tested on our own small cluster, PaStiX works better than superlu_dist and mumps.
However, PaStix was not installed on Kraken, while superlu_dist and mumps are installed as part of PETSc. I contact Kraken user support and was told the PETSc library was built by Cray and specially optimized for its structure. Do you happen to know the reason that PaStiX was not included in Cray's PETSc module? Thanks. Best, Xiangdong
