[FLASH-USERS] performance of parallel hdf5 on Bigben at PSC

[Shikui Tang]

Hi all,

  I have a serious problem when using the parallel hdf5 module to
restart from a checkpoint file. It takes about half an hour to read a
single variable to each node for a 1GB file. The same problem was
reported two year ago
(http://flash.uchicago.edu/pipermail/flash-users/2005-April/001938.html)
but I cannot find the follow-ups. Did anyone succeed in using the
parallel hdf5 module so far? Will the Flash center continue support such
issue on Flash2.5? Thanks!

Bests,
Shikui
