[petsc-users] KSPSolve takes more in each iteration

[Orxan Shibliyev]

I am solving a non-linear problem. Basically I do the following:

... Allocate A, x, b, ksp ...

for_loop
    ... call myFunction ...

where,

myFunction:
    ...
    startTime
    KSPSolve
    stopTime
    ....

I record time for KSPSolve. It takes more each time until it becomes
impossible to wait. I put the code on a cluster with (14 x 1) processors.
Any idea?
