help with random numbers and Rmpi
...ng() rand = sprng(); free.sprng() randarray = (double *)malloc(sizeof(double)*size); /*Gather random numbers from all C slave processes*/ /* Using randarray doesn't make sense since this should correspond to the rdata vector in the R master process */ MPI_GAther(&rand, 1, 1, MPI_DOUBLE, randarray, 1, MPI_DOUBLE, 0, all_processes); /*All done*/ MPI_Comm_free(&all_processes); MPI_Finalize(); exit(0); }

can someone help me understand LAM/MPI and Rmpi for use on a cluster
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!
