When eclipse first starts, it prompts for a workspace location. It's ok to accept the default of $HOME/workspace/ if you don't have a directory with that name, or you may select an alternate location.

You can begin exploring the wonderful world of eclipse resource managers from here. Use the Run Configurations under the Run menu if you have an application or job script ready to run on forge.

$ cd $HOME/vecadd $ tau_exec -T serial -XrunTAU-cupti-icpc -cuda ./vectorAdd $ # press return to exit the vectorAdd program $ paraprof & $ less /usr/apps/tools/tau/README.gpu # experiment with TAU_METRICS set in your environment |
Note for the bored: the dev/ directory contains trial1.cvp created by computeprof--the Nvidia-CUDA profiler that ships with CUDA. You can visualize it with the computeprof command on forge.
Paraprof setup on forge
- start paraprof from the ssh command line (not in Eclipse )
- File -> Database Configuration -> accept defaults , confirm new perfdmf database/schema and "Save Configuration"
- Exit paraprof (important because there can not be 2 paraprof processes trying to access your database at the same time...Eclipse will be starting one in the steps that follow)

You will need to fill out the Resources tab to describe the job you want to run. Select a queue (debug), Number of Nodes (1:ppn=4,flags=ADVRES:eclipse) , Mpirun command (mpirun_rsh), Number of cores (should be nodes*ppn or 4), and wall time (ten minutes = 00:10:00 ).
Finally, once the program runs, use TAU. Allow TAU to run in the background if the dialog box persists while the job is submitted.
