check4MKL {VCA}

Check for Availability of Intel's Math Kernel Library

Description

Majority of the code is borrowed from the Microsoft R Open Rprofile.site file. In case MKL can be detected this information will be stored in a separate envrionment, which other function know about. If so, an optimized version of function getGB will be used which used ordinary matrix-objects instead of matrices defined by the Matrix-package. This seems to accelerate computation time for large datasets by up to factor 30.

Usage

check4MKL()

Details

This function is for internal use only and therefore not exported.

Value

variable 'MKL' in envir "msgEnv" will be set to TRUE/FALSE
