This page has a list of known issues for the Cray compilers and compiler environment (all versions).

 

Cray ATP may not work


Older versions of Cray ATP did not work with OpenIFS.

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'.

Contact openifs-support@ecmwf.int for assistance.

 

 

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.
