Modules to load:
module load PGI CUDA-Toolkit
Command to compile:
pgcc -acc -ta=tesla:cc60 -o executable code.c
Command to run:

Alternatively use partition cfdg.p.
More info in the OpenACC Introduction.
Workshop
To copy data from the course directory:
cp -r /user/gilu2568/<dir> .
For profiling first get allocation:
salloc -p mpcg.p --gres=gpu:1
Create a script that runs an application, e.g. sincos.sh in the sincos example
#!/bin/bash module load hpc-uniol-env module load PGI module load CUDA-Toolkit ./sincos $@
Start the visual profiler in the background
nvvp &
Find out hostname for allocation
srun hostname
