ParallelSubmitAsync
Submits and expression for evaluation to any available parallel kernel and returns Promise with the result
ParallelSubmitAsync[expr_] _PromiseLaunch parallel Kernels beforehand using LaunchKernels[n_Integer]
Then[
ParallelSubmitAsync[URLRead["http://google.com"]],
Function[result, Beep[]; page = result]
]; The downloaded page will appear in a global symbol page. To share the definitions of any symbol from your main evaluation Kernel use DistributeDefinitions[sym_ | "ContextName"].
ParallelSubmitFunctionAsync
Similar to the previous one, but allows an inner expression make callback manually
ParallelSubmitFunctionAsync[f_, args__] _PromiseFor example
Then[
ParallelSubmitFunctionAsync[
Function[{url, cbk},
With[{data = URLRead["http://google.com"]},
cbk[data];
];
],
"http://google.com"
