[Hdf-forum] Slow conversion to binary using h5dump

[Mark Howison]

Hi, I tried converting a 108GB HDF5 file to binary using the "-b LE"
flag in h5dump, but it ran at a crawling pace, only about 4MB/s. This
is in comparison to an h5copy I did on the same machine (our SGI
Altix) that ran at 600MB/s. The filesystem is GPFS. Any ideas why
h5dump is having so much trouble? Is there a conversion phase (to LE)
that is bogging things down? Thanks, Mark
