Hello R users and developers, I would like to install Rmpi so that I may take advantage of all of the CPUs in my computer, but I cannot get it to install and I am not very good with linux so it is adding to the headache. I have looked through the help archive, but I have not been successful at getting Rmpi to work. I am not sure if I am even installing openMPI correctly in linux. I would really like to get Rmpi to work so that I can take advantage of libraries that use Rmpi and more importantly reduce my computation time from several days to maybe a day. I am using fedora 11 (64-bit) on a AMD phenom III (AM3) system and I am not an expert at linux so I run into trouble compiling and installing software out of inexperience. I would truly appreciated it if someone could please provide me with some instructions on how to get openMPI installed correctly on Fedora11 and Rmpi to work? I have included the processes I attempted below. Thank you, Alan Smith
