Abstract
A method and system for transposing a multi-dimensional array for a multi-processor system having a main memory for storing the multi-dimensional array and a local memory is provided. One implementation involves partitioning the multi-dimensional array into a number of equally sized portions in the local memory, in each processor performing a transpose function including a logical transpose on one of said portions and then a physical transpose of said portion, and combining the transposed portions and storing back in their original place in the main memory.
