Add CL args to control file system dir naming

[HenryYihengXu]

Macsio generates a large number of log files. Is it possible to redirect those files to another directory in the command line?

Hmm....it is designed to be very frugal w.r.t. to log files and I see only two from macsio itself there macsio-log.log and macsio-timings.log. All the other .silo files are data files probably run in file-per-processor mode. Changing command-line arguments regarding -parallel_file_mode MIF affects this. Or, for those plugins that support single-shared-file like HDF5 plugin, using -parallel_file_mode SIF.

Am I miss-understanding your question?

[HenryYihengXu]

Sorry for the unclear part. What I wanted to say are those .silo files. By command-line arguments, is there a way to put them into another directory instead of the current directory? They make the current directory kinda messy

[markcmiller86]

Ok, yeah, I get you. Currently, we don't support that. We should probably operate that way by default and maybe provide a CL arg. to override it.

I've modified the issue heading to reflect the desired enhancement.

Hi just want to check how's this issue going now. I want to run Macsio with Burst Buffers on Summit. I can write or read files in the burst buffer directory, but I cannot directly cd into the burst buffer directory. Therefore, if I want macsio to do I/O in that directory, I need to pass the directory to Macsio.
