getHW3threads() returns the current thread count.
setHW3threads() sets it and returns the new value.
Usage
getHW3threads()
setHW3threads(threads = 0L)
Arguments
- threads
Integer. Number of threads to use. 0 resets to
the default (50 percent of cores).
Value
Integer: the current (or newly set) thread count.
Details
The default is 50 percent of available cores, which can be overridden by the
environment variable R_HEATWAVE3_NUM_THREADS. The per-function
n_threads parameter, when greater than zero, takes precedence
over the package-level setting for that call.
Examples
getHW3threads()
#> [1] 5
old <- setHW3threads(2)
getHW3threads()
#> [1] 2
setHW3threads(0) # reset to default
#> [1] 5
