Gets freezeAndPtot fully working and successfully fuzzed on multi-GPU operation; Adds a 'cloned' partitioning type needed if a reduce occurs in the partitioning direction.
Aesthetic: use 'i' to loop over device indexes like other files.
Gets freezeAndPtot fully working and successfully fuzzed on multi-GPU operation; Adds a 'cloned' partitioning type needed if a reduce occurs in the partitioning direction.
Use only 8K threads for directional max find for smaller final reduce.
Makes unit test work with 1-d output arrays when freezeAndPtot is tested in 2d.
Sets minimum non-unit dimension for tests to 6; Otherwise risks causing partitioned tests to malfunction.
