[petsc-users] VecView() comparison: BINARY vs HDF5

[Mohamad M. Nasr-Azadani]

Hi all,

I was using VecView() to write the data to file (a vector of total size
50*20*10 (3D DMDA)).
I compared the times for two cases: PETSc's binary and also HDF5.
I get an enormous difference between the times I get for these two cases
(this test is done using only one processor)

HDF5: 16.2 (sec)
Binary: 0.33 (sec).

I am using HDF5 VecView() as a magic black box writer to dump the field
quantities. And I am not an expert on it but this order of magnitude seems
a bit strange to me.

Any inputs are appreciated!
Best,
Mohamad
