[Darshan-users] Darshan error

[Phil Carns]

Hi Florin,

I'm not exactly sure.  Is the /sandbox/darshan_logs directory (and all 
of the subdirectories created by mk-log-dirs.pl) accessible from all of 
the processes in the MPI job?  All of them will need to be able to write 
to it at MPI_Finalize() time.
