I/O performance metrics
S-01515
As a Tullow Geophysicist I want the PIOL to be able to provide I/O performance metrics because it will give me a better idea of whether I am using my hardware efficiently.
PreDev Notes:
ADDME
Implementation Notes:
Find ways to ensure new interfaces include the metrics if possible
Test by introducing a delay and see it dominates
Cray MPI has nice performance reporting!
System Test Changes:

Success Criteria:
-
Read/write bandwidth can be accessed by the end user -
Total data read/written can be access by the end user -
Quantify I/O saved through caching
