[Rcpp-devel] OpenMP and Rinside

[David Ibarra Gómez]

I've got the whole thing working with MPI, after playing aroud the makefile and the include order (I'm using many different libraries RInside, Cassandra, Mongo, CBC...).

Thank you for the include MPI examples and the makefile.

I used Rcpp with OpenMP in one of my packages (the new version is not
on CRAN yet, only on github), so I can help with putting together an
example.  I'm at conferences this week and next week, though, so I'm a
bit constrained with time right now.
