$DistributedDefinitions
gives the list of all symbols whose definitions have been distributed to parallel kernels.
Details
- $DistributedDefinitions includes all symbols whose definitions have been distributed to parallel kernels either automatically or by using DistributeDefinitions.
- $DistributedDefinitions returns a list of symbols wrapped in HoldForm.

Automatically distribute the value of a symbol:
kid := $KernelIDParallelEvaluate[kid]$DistributedDefinitionsDistribute the definition of a function:
f[x_] := 2 * $KernelIDDistributeDefinitions[f]$DistributedDefinitionsParallelEvaluate[f[2]]Possible Issues (3)
By default, symbols in the current context are automatically distributed:
mat = RandomInteger[{0, 9}, {2, 2}]ParallelEvaluate[Inverse[mat]]$DistributedDefinitionsClearing the distributed definitions may seem to work:
ClearDistributedDefinitions[mat]$DistributedDefinitionsAs soon as mat is used again in a parallel computation, its definition will be distributed automatically again:
ParallelEvaluate[Inverse[mat]]$DistributedDefinitionsDisable automatic distribution of definitions if you wish to control distribution of definitions manually:
$DistributedContexts = None;a = 42;The definition of a has not been distributed to parallel subkernels:
ParallelEvaluate[Head[a]]$DistributedDefinitionsDistribute the definition of a manually:
DistributeDefinitions[a]ParallelEvaluate[Head[a]]$DistributedDefinitionsText
