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.
