In future: Unified Parallel and Distributed Processing in R for Everyone

Request a core for multicore processing

Description

If no cores are available, the current process blocks until a core is available.

Usage

requestCore(await, workers = availableCores(), timeout, delta, alpha)

Arguments

await	A function used to try to "collect" finished multicore subprocesses.
workers	Total number of workers available.
timeout	Maximum waiting time (in seconds) allowed before a timeout error is generated.
delta	Then base interval (in seconds) to wait between each try.
alpha	A multiplicative factor used to increase the wait interval after each try.

Value

Invisible TRUE. If no cores are available after extensive waiting, then a timeout error is thrown.
