Hi all! I have a quad core computer and I'd like to run some Rmpi code. However, I would like to be able to demonstrate that all 4 cores are running. Is there a way to do that, please? Also, would it be better to run snow for such a demo, please? thanks, Erin -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences University of Houston - Downtown mailto:

I'm fairly astute at C and R but new to parallelization. Would someone be willing to provide help in the form of a simple example that parallelizes an R function from the inside of a C routine? If so, write me back at izmirlig at mail.nih.gov Thanks!

Hi list, It appears there is a problem with the OpenMPI I/O library on CentOS 6.2 & 6.3 (package openmpi-1.5.4-1.el6.x86_64). When I compile the attached program it ends up in the error path since MPI_File_open returns 16. The corresponding (unhelpful) message is: MPI_ERR_OTHER: known error not in list I couldn't find any pointers on the net and the same program works with OpenMPI
