qimpy.mpi.globalreduce

Reduction of MPI-distributed tensors to scalars. The functions of this module correctly handle zero-sized pieces of distributed tensors on certain processes, whic is a frequently encountered and cumbersome corner case in such global reductions.

Functions

sum	Global sum of tensor v distributed over comm.
prod	Global product of tensor v distributed over comm.
min	Global minimum of tensor v distributed over comm.
max	Global maximum of tensor v distributed over comm.
all	Global minimum of tensor v distributed over comm.
any	Global maximum of tensor v distributed over comm.
