Cray ATP does not work
This is caused by the way IFS creates its own signal handler. To enable Cray ATP set:
export DR_HOOK_IGNORE_SIGNALS=-1
in the job script to completely disable any signal trapping by the IFS signal handler code 'DrHook'.

CrayPAT does not work
This is a result of the way in which the OpenIFS is compiled. More information on this and the resolution is described here.
