$DistributedContexts

$DistributedContexts

is the default value of the DistributedContexts option of functions such as ParallelTable and ParallelMap.

Details

  • Before a parallel computation, definitions of symbols to be evaluated in a parallel kernel will automatically be distributed to all kernels, provided these symbols belong to a context given in the DistributedContexts option.
  • The initial value is $DistributedContexts:=$Context, which distributes definitions of all symbols in the current context, but does not distribute definitions of symbols from packages.
