class Context[source]¶

Global context

rank¶: rank of the current process (0, 1, …, procs-1)

procs¶: number of MPI ranks

comm¶: MPI.COMM_WORLD

MPI¶: mpi4py’s MPI module

iterates(n, robin=False)[source]¶

Create a DFM from a sequence of numbers.

Parameters

n – The number of iterates
robin – If True, assignments are done round-robin, so rank 0 will have 0, procs, 2*procs, … rank 1 will have 1, procs+1, 2*procs+1, …

Returns

DFM holding numbers 0, 1, …, n-1
