[R-pkg-devel] multithreading in packages

[Vladimir Dergachev]

  I am considering adding multithreading support in my package, and would 
appreciate any suggestions/comments/opinions on what is the right way to 
do this.

   * My understanding from reading documentation and source code is that 
there is no dedicated support in R yet, but there are packages that use 
multithreading. Are there any plans for multithreading support in future R 
versions ?

   * pthread or openmp ? I am particularly concerned about interaction with 
other packages. I have seen that using pthread and openmp libraries 
simultaneously can result in incorrectly pinned threads.

   * control of maximum number of threads. One can default to openmp 
environment variable, but these might vary between openmp implementations.

thank you very much
