I am trying to parallelize part of a C function that is called from R (via .C) using OpenMP's "parallel for" pragma. I get mixed results: some runs finish with no problem, but some lead to R crashing after issuing a long error message involving memory violations.
I found this post, which describes how a .Call() function can be made to avoid crashing R by raising the stack limit: http://www.r-bloggers.com/using-openmp-ized-c-code-with-r/ However, trying this in my .C function doesn't help things. Any suggestions/tips on whether I can safely use OpenMP inside a .C function, and if yes how?
