  • Archer/cce8.3.7

    v21 v22  
     1''Monday June 29th'' 
     2* The default ARCHER Cray compiler is now cce8.3.7. NCAS-CMS have modified the UM infrastructure so that builds pick up compatible libraries and modules. Previous ''ad-hoc'' instructions for building need no longer be followed an indeed may cause confusion. 
     3* Models built with cce8.2.1 should run OK under the upgraded environment 
     4* Do not perform incremental builds mixing code built under cce8.2.1 with that built under cce8.3.7. This means that your first compilation job after the upgrade should be a complete rebuild; subsequent incremental builds will be OK.

    19As part the regular software upgrade cycle, ARCHER will remove the Cray cce8.2.1 compiler on June 24th. cce8.2.1 has been the UM compiler since ARCHER became operational and we have maintained its use to minimize possible disruption but it does appear to be a source of OOM errors in some long-running UM jobs. These OOM errors have not appeared in jobs running code compiled with later Cray compilers, so it is timely to upgrade to the current ARCHER default - cce8.3.7.
