Scalapack/BLACS Typemismatch warning / blacs_* fails somet

Postby C_Clear » Fri Jan 18, 2013 7:05 am

Hello ,
I have a Problem with my Installation of ScaLapack.
I have successfully compiled with the ScaLapack Installer using gcc 4.6.2 (needed bei the ACML Blas).
But while compilation multiple of the following Warning occur .
Code: Select all
Warning: Type mismatch in argument 'erribuf' at (1); passed REAL(8) to INTEGER(4)

     $                               MEM(ERRIPTR), MEM(ERRDPTR), ISEED)

But my Scalapack Library is build at the end.

I use that Library then to link like
Code: Select all
mpic++ -o matrix -lgfortran matrix.o stage.o dSFMT.o ../acml_scalapack_lib/libscalapack.a ../acml_scalapack_lib/libacml.a

I have tried to run my code locally on my machine and i succeed.
At my workplace we use gridengine to submit jobs to our cluster.
As long as i specify less then about 50 nodes ,my program exits as predicted (created matrices/using pzgesv to solve).
When i use much more nodes (400) the job fails giving me the error messages from many nodes:
Code: Select all

[lxb855:13299] *** End of error message ***

I am unsure why this behaviour occurs but since it always hangs in some "blacs_*"
routine(like [lxb855:13299] [ 6] matrix(blacs_pinfo_+0xbd) [0x415cfd]) I think it might have something to do with my BLACS installment.

I dont really know how to handle this .
How can I fix this?
thanks in Advance
