[petsc-users] -log_summary output

[ilyas ilyas]

Hello,

Would you please help me to understand two attached -log_summary outputs.
Both are from same cfd-petsc code, taken at different times at the end of
first time-step.

Domain : 256^3, periodic (defined in DA's)
Ncores : 256

After a couple of hundered iterations, one or more cores killed/dumped and
my code exits.This is not an issue with a coarse resolution (say 32^3,64^3)
May this be related to my code? (Assuming enough memory available in the
system). What is wrong with MatXXX ?

Thanks a lot,

Ilyas.
