Load balancing grid decomposition for PUGH.
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
