Memory bound OpenMP applicaton with significant time spent on waiting memory requests from DRAM.

MPI application with significant time spent on MPI communication (collective operations).

Rank-to-rank communication time of MPI application.

What's new for 2019 Update 2:

Full-featured OpenMPI* support
Improved vectorization efficiency metrics
MPI Imbalance time is no longer calculated on the default stat level 1 to minimize collection overhead on that level
aps-report: added option to display statistics only for the selected set of MPI functions
MPI collector general optimizations
