This script allows for generating nvprof output files based on the hostname of a Cray XK7 compute node.

nvprof.sh

#!/bin/bash
# USAGE: Add between aprun options and executable
# For Example: aprun -n 16 -N 1 ./foo arg1 arg2
# Becomes: aprun -n 16 -N 1 ./nvprof.sh ./foo arg1 arg2

# Give each *node* a separate file
LOG=profile_$(hostname).nvp

# Stripe each profile file by 1 to share the load on large runs
lfs setstripe -c 1 $LOG

# Execute the provided command.
exec nvprof -o $LOG $*
