Latest HECToR jobs are xdbuc (pathscale) and xdbud (PGI).
Only a couple of changes are required to go from a pathscale to PGI run. The differences between the jobs above are:
$FAMOUS_DIR/overrides/pgi_O2_Kieee_fastsse
Pathscale gives slightly better performance than PGI for FAMOUS and for the UM generally. See timings.
