Cray XK6/XK7

Cray XK6 machines

1. Configuring TAU:

module load cudatoolkit
./configure -arch=craycnl -cuda="$CRAY_CUDATOOLKIT_DIR" -cudalibrary="$CRAY_CUDATOOLKIT_POST_LINK_OPTS" -bfd=download

Setup your environment:

export PATH=<path to tau2>/craycnl/bin:$PATH
export LD_LIBRARY_PATH=<path to tau2>/craycnl/lib:$LD_LIBRARY_PATH

2. CUDA

Build as normally would, and modify your run command to be:

aprun -N 1 tau_exec -T serial,cupti -cupti ./matmult

3. OpenACC

Both PGI and Cray uses the CUDA driver API to interact with the GPU, so setup TAU to collect those calls:

export TAU_CUPTI_API=driver

Compile as normally would and run with tau_exec as well:

aprun -N 1 tau_exec -T serial,cupti -cupti ./matmult
