Using HP Caliper
HP Caliper is a general-purpose performance analysis tool for
applications, processes, and systems.
HP Caliper allows you to understand the performance and execution of
an application, and identify ways to improve runtime performance.
NOTE When running HP-MPI applications under HP Caliper on Linux hosts, it
may be necessary to set the HPMPI_NOPROPAGATE_SUSP environment
variable to prevent application aborts.
% setenv HPMPI_NOPROPAGATE_SUSP 1
% export HPMPI_NOPROPAGATE_SUSP=1
