[FLASH-USERS] H5Screate_simple(): zero sized dimension for non-unlimited dimension

[kunal rao]

Hi,

I am running FLASH 3.2 on my laptop on a virtual machine running Ubuntu
9.10. I have configured the code using:
$./setup Sedov -auto -makefile=gfortran

I am able to run the executable for a single process using $./flash3 . But
when I try to run it on 2 processes using

$mpirun -np 2 ./flash3

I get the following error:

Driver_abortC called
Error: negative return from memspace H5Screate_simple
Calling MPI_Abort for immediate shutdown
HDF5-DIAG: Error detected in HDF5 library version: 1.6.10 thread 0.  Back
trace follows.
  #000: H5S.c line 1595 in H5Screate_simple(): zero sized dimension for
non-unlimited dimension
    major(01): Function arguments
    minor(05): Bad value

This problem was addressed in one of the previous archived emails. The
response to that by Chris was that:

-------------------------------------------------

I think this is happening because there are zero blocks on at least
one processor. You can check whether this is the case by looking in
the flash log file from your run. Look for the last
amr_refine_derefine message of the form:

[GRID amr_refine_derefine] min blks 17 max blks 18 tot blks 69

I expect there is a min blks 0 in your message. A temporary
workaround is to run your application on fewer processors.

-------------------------

I checked in my sedov.log file and it is 0. This is what i see in the
sedov.log file:

----------------------------

WARNING : Adaptive Grid did not find any variable to refine
 [ 06-03-2010  11:55:51.588 ] [GRID amr_refine_derefine]: initiating refinement

 [GRID amr_refine_derefine] min blks 0    max blks 1    tot blks 1

 [ 06-03-2010  11:55:51.743 ] [GRID gr_expandDomain]: iteration=1,
create level=2

-----------------------------------------------------------

The temporary workaround was to use fewer processes. But I am not able
to run on even 2 processes.

Can you please tell me if there is a solution for this.

Thanks & Regards,
Kunal
