Ticket #552 – Description
v3 v4 46 46 That is, we do a special exception for distribute-memory cases. This change is necessary in your customized versions of '''ana_grid.h''' and '''ana_psource.h'''. 47 47 48 * Notice that we no longer use the '''TILE''' (uppercase) as argument to the kernel routines. We use '''tile''' (lowercase) instead. This was important in previous versions of distributed-memory code where '''TILE''' was replaced with '''!MyRank''' during C-preprocessing. Be careful with this one...48 * Notice that we no longer use the '''TILE''' (uppercase) as argument to the kernel routines. We use '''tile''' (lowercase) instead.
