WGCNA (version 1.43)

allowWGCNAThreads: Allow and disable multi-threading for certain WGCNA calculations

Description

These functions allow and disable multi-threading for WGCNA calculations that can optionally be multi-threaded, which includes all functions using cor or bicor functions.

Usage

allowWGCNAThreads(nThreads = NULL)
enableWGCNAThreads(nThreads = NULL)
disableWGCNAThreads()
WGCNAnThreads()

Arguments

nThreads

Number of threads to allow. If not given, the number of processors online (as reported by system configuration) will be used. There appear to be some cases where the automatically-determined number is wrong; please check the output to see that the number

Value

• allowWGCNAThreads, enableWGCNAThreads, and disableWGCNAThreads return the maximum number of threads WGCNA calculations will be allowed to use.

Details

allowWGCNAThreads enables parallel calculation within the compiled code in WGCNA, principally for calculation of correlations in the presence of missing data. This function is now deprecated; use enableWGCNAThreads instead.

enableWGCNAThreads enables parallel calculations within user-level R functions as well as within the compiled code, and registers an appropriate parallel calculation back-end for the operating system/platform.

disableWGCNAThreads disables parallel processing.

WGCNAnThreads returns the number of threads (parallel processes) that WGCNA is currently configured to run with.
