Abstract:
Methods, apparatus, and products are disclosed for performing an all-to-all exchange on n number of data buffers using XOR swap operations. Each data buffer has n number of data elements. Performing an all-to-all exchange on n number of data buffers using XOR swap operations includes for each rank value of i and j where i is greater than j and where i is less than or equal to n: selecting data element i in data buffer j; selecting data element j in data buffer i; and exchanging contents of data element i in data buffer j with contents of data element j in data buffer i using an XOR swap operation.
