Consider the all-reduce operation in which each processor starts with an array of m words, and needs to get the global sum of the respective words in the array at each processor. This operation can be implemented on a ring using the following alternative: Single node accumulation of the elements of the array, followed by a one-to-all broadcast of the result array. For the above case, , compute the run time in terms of m, ts, and tw

Question
  1. Consider the all-reduce operation in which each processor starts with an array of m words, and needs to get the global sum of the respective words in the array at each processor. This operation can be implemented on a ring using the following alternative:
  • Single node accumulation of the elements of the array, followed by a one-to-all broadcast of the result array.

For the above case, , compute the run time in terms of m, ts, and tw.
