Parallel

ParallelSubmitAsync

Submits and expression for evaluation to any available parallel kernel and returns Promise with the result

ParallelSubmitAsync[expr_] _Promise

tip

Please, launch 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__] _Promise

For example

Then[
	ParallelSubmitFunctionAsync[
		Function[{url, cbk}, 
			With[{data = URLRead["http://google.com"]},
				cbk[data];
			];
		],
		
		"http://google.com"
	],
	
	Function[result, Beep[]; page = result]	
];
