[petsc-users] reg: ex7.c takes large memory and gets killed

I am running "mpirun -np 64 -hostfile /cluster/hostnames ./ex7 -f1 A1 -f2
B1 -st_type sinvert -evecs outvec"

It works for small matrices, it uses noticeable memory for small matrices

However when I run with 39200x39200 complex matrices, it uses all the 480
GB ram and swap and gets killed.

Am I doing something wrong ? Is there a solution.

Pls let me know
