Keeneland

Guide for using TAU on Keeneland

Setting up environment

We'll have a module for TAU setup short but for now, setup your environment this way:

   %> export PATH=/nics/c/home/biersdor/tau2/x86_64/bin/:$PATH
   %> export LD_LIBRARY_PATH=/nics/c/home/biersdor/tau2/x86_64/lib/:$LD_LIBRARY_PATH

Running CUDA applications

Both CUDA and OpenCL are instrumented dynamically through library preloading, use the tau_exec script to run the CUDA application:

   %> tau_exec -T serial -cuda ./Stencil2D

The -T serial specifies with TAU configuration to use, you can omit this for MPI applications and run:

Trouble-shooting

• CPU side looks fine but o GPU profile/trace generated.
