DistributedContexts

DistributedContexts
is an option for various parallel computing functions that specifies which definitions for symbols appearing in an expression should be distributed to all parallel kernels.
MORE INFORMATION
  • Possible settings include:
"context`"all symbols in context
{"ctx1`","ctx2`",...}all symbols in the given contexts
Nonedo not distribute any definitions
Alldefinitions of all symbols
Automaticall contexts appearing in expr
$Contextall symbols in the current context
  • Definitions of symbols appearing in an expression set for parallel evaluation that match the given contexts are distributed automatically before the parallel evaluation, effectively using DistributeDefinitions.
  • Definitions for symbols on which other distributed definitions depend are also distributed, as long as they belong to one of the given contexts.

Basic Examples   (4)
By default, definitions in the current context are distributed automatically in a parallel computation:
Do not distribute definitions of functions defined:
Distribute definitions for all symbols in all contexts appearing in a parallel computation:
Distribute only definitions in the given contexts:
