[SOLVED] How can I find hpcviewer in order to visualize trace data generated by hpcrun?

Issue

My question is about hpcviewer which is a tool to visualize trace data generated by hpcrun.

I succeeded to install hpctoolkit but I have a problem finding hpcviewer. To test the toolkit, I created a simple hello_world program in C (with OpenMP) and executed the following block of commands as shown in https://wiki.mpich.org/mpich/index.php/HPCToolkit_by_example:

gcc -O3 -fopenmp  hello_world.c -o hello_world -lm
hpcstruct ./hello_world
hpcrun -t ./hello_world
hpcprof -S hello_world.hpcstruct -I . hpctoolkit-hello_world-measurements
hpcviewer hpctoolkit-hello_world-database

Unfortunately, I get an error which is "hpcviewer: command not found". I installed hpcviewer yesterday using

spack install hpcviewer

Solution

The hpcviewer command is not found because the hpctoolkit has not been loaded.

You should execute the following command before asking for hpcviewer to visualize trace data generated by hpcrun:

spack load hpctoolkit 

Then you can execute

hpcviewer hpctoolkit-"name_of_exec"-database
