Hi,

I am reading 1 (103G) file with parallel-hdf5 using 8, 64 and 512 cores.
Reports from darshan/229 (see attached) looks good for 8 and 64 cores:
  >   8cores *  13G/core ~= 103G: ok
  >  64cores * 1.6G/core ~= 103G: ok
but
  > 512cores * 0.13G/core ~= 67G != 103G

Does it mean only 67G are being read ?
I am attaching the logs for reference.

Regards, jg.
