Re: Petsc Error



Hi,

I ran the same command again, running top, and got the result

Mem:   6220940k total,  5879056k used,   341884k free,   143992k buffers
Swap:  1951888k total,     2584k used,  1949304k free,  2363516k cached

just before it crashed. I have a 2 processor machine with total 6 GB of memory (2 times 3 gb?), so I don't think it should be out of memory. How can I verify this for sure?

Thanks,

Berend.

Hi,

On the command

  ierr = DACreateLocalVector(da,g); CHKERRQ(ierr);

I get the error


[0]PETSC ERROR: PetscMallocAlign() line 61 in src/sys/memory/mal.c Memory requested 6050600 [0]PETSC ERROR: PETSC: Attaching gdb to Debug/MultiFlow of pid 19087 on display :0.0 on machine tfdpc102


What does it mean exactly? Out of memory?

Yes. This is strange. The line above these two should read "Out of memory".

Thanks,
