BP4 with NVME on Summit
Created by: jychoi-hpc
I am trying to use BP4 with NVME on Summit but getting the following error:
[DELTAF:54] ERROR: couldn't open file ../coupling/xgc.wdm.f0.0.bp/data.26, check permissions or path existence, in call to POSIX open
[DELTAF:54]
[DELTAF:54] adios2_end_step
[DELTAF:54] FORTRAN STOP
With the following node-local
parameter setting in BP3, it works:
<parameter key="node-local" value="On"/>
I was told node-local
parameter will let each process create own directory structure locally on NVME.
