*	Apply Frank Loeffler's patch to improve the processor distribution of	schnetter	2005-09-26
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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

\| \| \| \| \| \| \| \|	Removed empty "Load Balancing" section (this documentation is provided by the "Processor Decomposition" section). git-svn-id: http://svn.cactuscode.org/arrangements/CactusPUGH/PUGH/trunk@372 b61c5cb5-eaca-4651-9a7a-d64986f99364

*	Filled out the maxskew variable which wasn't being set.	allen	2001-10-28
\| \| \| \| \| \| \| \| \| \| \| \|	Also added a private parameter "info", at the moment it can take the values none or load, if load is chosen it shows the actual load on each processor. I want to add more options for printing out the local domain etc on each processor. Documented the maxskew variable, and how to spot if you are using MPI or not. git-svn-id: http://svn.cactuscode.org/arrangements/CactusPUGH/PUGH/trunk@355 b61c5cb5-eaca-4651-9a7a-d64986f99364
*	Initial doc for PUGH.	allen	2001-07-10
	Still need to add details about processor decomposition, and the default load distribution wrt ghostzones, periodicity and that. git-svn-id: http://svn.cactuscode.org/arrangements/CactusPUGH/PUGH/trunk@339 b61c5cb5-eaca-4651-9a7a-d64986f99364
