[petsc-users] %T (percent time in this phase)

[Karthikeyan Chockalingam - STFC UKRI]

Hello,

I ran ex45 in the KPS tutorial, which is a 3D finite-difference Poisson problem. I noticed from the output from using the flag -log_summary that for various events their respective %T (percent time in this phase) do not add up to 100 but rather exceeds 100. So, I gather there is some overlap among these events. I am primarily looking at the events KSPSetUp, KSPSolve, PCSetUp and PCSolve. Is it possible to get a mutually exclusive %T or Time for these individual events? I have attached  the log_summary output file from my run for your reference.

Thanks!
Karthik.
