[petsc-users] insufficient virtual memory?

[Park, Heeho via petsc-users]

Hi PETSc developers,

Have you seen this error message?

      forrtl: severe (41): insufficient virtual memory

We are running about 36 million degrees of freedom ( ~ 2.56 GB) and it is 
failing with the error message on our HPC systems.
Ironically, it runs on our laptop (super slow.)

      type: seqbaij
      rows=46251272, cols=46251272
      total: nonzeros=323046210, allocated nonzeros=323046210
      total number of mallocs used during MatSetValues calls=0
          block size is 1

Does anyone have experience encountering this problem?

Thanks,

Heeho Daniel Park
