I downloaded the classic scalapack example: example1.f, and compiled with:
- Code: Select all
$ mpif77 -o example example1.f /usr/lib/libscalapack.a /usr/lib/libblacsF77init.a /usr/lib/libblacs.a /usr/lib/libblacsF77init.a /usr/lib/atlas/libblas.a
some of that .a files are symbolic links to the specific archive. That compilation finish without any problem.
When i try to run it with:
- Code: Select all
$ mpirun -np 6 example
Then i get the following error message:
- Code: Select all
-----------------------------------------------------------------------------
One of the processes started by mpirun has exited with a nonzero exit
code. This typically indicates that the process finished in error.
If your process did not finish in error, be sure to include a "return
0" or "exit(0)" in your C code before exiting the application.
PID 18303 failed on node n0 (192.168.0.1) due to signal 11.
-----------------------------------------------------------------------------
As i can remember it is a segmentation fault .
I added some debuging output to see where it stops and the line responsable here is:
- Code: Select all
CALL SL_INIT( ICTXT, NPROW, NPCOL )
near line 47.
I have seen a similar problem when trying to use scalapack from R (RScaLAPACK), it always outputs an error message indicating that it can't spawn child proceses when trying to create some slaves
Running other mpi programs work fine. I really apreciate if someone can help on that problem.
