Teuchos: timers seem to overflow somehow
Created by: aprokop
In a run, we got the following results in the final summarize()
call for Teuchos timers:
Belos: ICGS[2]: Ortho (Inner Product) -8613 (2.173e+04) 114.9 (2.173e+04) 617.8 (2.173e+04) 0.00529 (2.173e+04)
...
MueLu: Hierarchy: Setup (total) -6721 (600) 1532 (676.1) 2193 (992) 2.266 (676.1)
So, somehow, the times become negative. More investigation shows that for instance for the MueLu hierarchy setup timers, they accumulate till about 406 seconds, and go negative the next setup.
This sounds like an integer overflow problem though totally unclear how integers are involved.
The run was done on 1152 processors.
