Description

S3L_trans performs a generalized transposition of a parallel array. A generalized transposition is defined as a general permutation of the axes. The array axis_perm contains a description of the permutation to be performed.

The distribution characteristics of a and b must be compatible--that is, they must have the same rank and type and corresponding axes must be of the same length.

A faster algorithm is used in the 2D case when the array meets the following conditions:

• The first axis of the array is local.

• The second axis of the array is global.

• The size of each dimension is divisible by the number of processes.

• The blocksizes are equal to the result of the division.
