R package that automatically uses several cores?

Question

I have noticed that R only uses one core while executing one of my programs which requires lots of calculations. I would like to take advantage of my multi-core processor to

Answer 1

Microsoft R Open includes multi-threaded math libraries to improve the performance of R.It works in Windows/Unix/Mac all OS type. It's open source and can be installed in a separate directory if you have any existing R(from CRAN) installation. You can use popular IDE Rstudio also with this.From its inception, R was designed to use only a single thread (processor) at a time. Even today, R works that way unless linked with multi-threaded BLAS/LAPACK libraries.

The multi-core machines of today offer parallel processing power. To take advantage of this, Microsoft R Open includes multi-threaded math libraries. These libraries make it possible for so many common R operations, such as matrix multiply/inverse, matrix decomposition, and some higher-level matrix operations, to compute in parallel and use all of the processing power available to reduce computation times.
