Callpath Results

TAU was configured with:

-mpiinc=/usr/local/lam-mpi/include/ -mpilib=/usr/local/lam-mpi/lib -PROFILECALLPATH -useropt=-O3

Highlighted below in the mean profile callpath view are several key numbers. First the 2112.575 second overall runtime. Next, we see that 165.938 seconds are spent in the task ICE::advectAndAdvanceInTime.

Of that 165.938 seconds, 85.071 are spent in computation (runTask()), and 53.622 seconds are spent in MPI_Waitsome()
