Description
If no cores are available, the current process blocks until a core is available.
Usage
requestCore(
await,
workers = availableCores(),
timeout = getOption("future.wait.timeout", 30 * 24 * 60 * 60),
delta = getOption("future.wait.interval", 0.01),
alpha = getOption("future.wait.alpha", 1.01)
)
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 |
