Re: [petsc-users] PetscLogView produces nan's instead of timing data when using GPUs

It prints Nan to indicate that the time for that event is not known accurately. But the times for the larger events that contain these events are known. So for example the time for KSPSolve is know but not the time for VecNorm. The other numbers in the events, like number of times called

[petsc-users] PetscLogView produces nan's instead of timing data when using GPUs

Hi PETSc-developers, I'm having trouble with getting performance logs from an application that uses PETSc. There are no issues when I run it on a CPU, but every time a GPU is used there is no timing data and almost all times are replaced by times that are just `nan` (on two different clusters). I
