Hi,
has anyone experience with compiling R (R-2.9.2) with mpicc?
Due to our hardware architecture (altix) we have to compile R with mpicc
and than include Rmpi. Compiling R with gcc and than including Rmpi is
not working with the altix.mpi version.
Unfortunately the R version compiled with mpicc is about 3-5 times
slower than the R version compiled with gcc! Any ideas for that?
Thanks
Markus Schmidberger
