学弟遇到的问题
HPL ERROR from process # 0, on line 419 of function HPL_pdinfo:
>>> Need at least 4 processes for these tests <<<
HPL ERROR from process # 0, on line 621 of function HPL_pdinfo:
>>> Illegal input in file HPL.dat. Exiting ... <<<
具体原因是
hpl下的Make.Linux_PII_CBLAS指定了mpi是自己装的MPICH,然后运行bin/Linux_PII_CBLAS/xhpl还用module load openmpi
