--------------------------------------
Hi [~pbacsko]!
It's also worth to mention here for reference that what type of output you plan
the script will produce based on the output of "aocl diagnose". Is this going
to be the same fpga device specification string as the value of property
{{yarn.nodemanager.resource-plugins.fpga.available-devices}} would contain or
any other intermediate format?
