[petsc-users] matload big matrix

[Wen Jiang]

Hi,

I am trying to load a big matrix(size 552147 by 552147) from a binary
file(around 2GB). But I found my code seems to get stuck at the loading
stage. I copied the last a few info output below

[0] PetscCommDuplicate(): Using internal PETSc communicator 1140850688
-2080374780
[0] PetscFileRetrieve(): Found file l2projphim.dat
[0] PetscFileRetrieve(): Found file l2projphim.dat.info
[0] PetscOptionsInsertFile(): Opened options file l2projphim.dat.info

Do you have any suggestions? Thanks.

Regards,
Wen
