* Provide new overload function for CCTK_SyncGroupsByDirI().tradke2006-07-06
| | | | | | | | | | | Do not overload CCTK_SyncGroup() anymore by default. This patch requires the most recent changes in the flesh API to provide the new overloadable function CCTK_SyncGroupsByDirI(), as discussed in thread http://www.cactuscode.org/old/pipermail/developers/2006-June/004933.html. git-svn-id: http://svn.cactuscode.org/arrangements/CactusPUGH/PUGH/trunk@482 b61c5cb5-eaca-4651-9a7a-d64986f99364

* Changes from Dylan Stark to allow registration of topologygoodale2005-12-14
| | | | | | | | | | | | | | | | | | | | routines and introducing a physical to logical processor mapping. Now it is possible to register custom topology routines if you don't like the two ones we have at the moment (the traditional one and the new one from Frank Loeffler). You can also provide routines to optimise the placement of neighbouring processes on the processors by giving a custom mapping from the numbers PUGH uses for the processors to the actual MPI processor. Please treat this registration as semi-volatile for the moment and coordinate with Dylan if you fancy using it. git-svn-id: http://svn.cactuscode.org/arrangements/CactusPUGH/PUGH/trunk@475 b61c5cb5-eaca-4651-9a7a-d64986f99364

* Apply Frank Loeffler's patch to improve the processor distribution ofschnetter2005-09-26
| | | | | | | | | | | | | | | | | | | | | | | | PUGH: Up to now, PUGH does not take the actual grid size into account while setting the number of processors/domains in each direction. This gives problems, e.g. using boxes like 200x7x7 (with 3 ghostzones). It also does not really do a good job in situations with non near-cubic domains (like in bitant mode it devides first in the z-direction, which is usually the smallest). I inserted another decomposition algorithm which is looking for the longest direction and devides this if possible. Because it was done to be easy to understand, it can fail in certain situations, in which it is gracefully falling back to the old decomposition (e.g. a cubic box and 9 processors). To include this algorithm I added a keyword "automatic_old" to PUGH::processor_topology. The new behaviour is the default; this keyword re-enables the old behaviour. git-svn-id: http://svn.cactuscode.org/arrangements/CactusPUGH/PUGH/trunk@471 b61c5cb5-eaca-4651-9a7a-d64986f99364

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Contributed by Matei Ripeneau Here are his notes (hopefully there will soon be PUGH docs to add them to): 1. Purpose Allow manual (user specified) grid partitioning 2. Parameters I've added the following parameters to ./PUGH/param.ccl KEYWORD partition "Is the partition manual/automatic" { "automatic" :: "even implicit partition" "manual" :: "specified by partition_#d_XYZ .." } "automatic" STRING partition_1d_X "Tells how to partition on direction X" ... STRING partition_2d_X "Tells how to partition on direction X" ... STRING partition_2d_Y "Tells how to partition on direction Y" ... STRING partition_3d_X "Tells how to partition on direction X" ... STRING partition_3d_Y "Tells how to partition on direction Y" ... STRING partition_3d_Z "Tells how to partition on direction Z" ... (all these strings have default "") How to specify a manual partition? Simpler to explain using an example: partitioning a grid space with 30 x 30 x 30 points for a configuration with 8 processors can be specified as: PUGH::partition = "manual" PUGH::partition_1d_X = "" // uses default PUGH::partition_2d_X = "16:14" PUGH::partition_2d_Y = "7:9:5:9" PUGH::partition_3d_X = "16:14" PUGH::partition_3d_Y = "12:18" PUGH::partition_3d_Z = "17:13" Even if PUGH::partition = "manual" an empty string like PUGH::partition_1d_X = "" will lead to default (even) partition on that direction git-svn-id: http://svn.cactuscode.org/arrangements/CactusPUGH/PUGH/trunk@174 b61c5cb5-eaca-4651-9a7a-d64986f99364
