Little program to compute the mean and the standard deviation of an array of size n filled with random integers between 0 and 50 with Open MPI Program developed for an assignment during my fourth year in the Griffith College (Dublin)
This program needs Open MPI to work. Open MPI is a library for distributed system in C++.
Try to follow this steps to install open MPI on your system :
- Windows: Sorry, cannot help you on this one :(
- Mac OS: Instructions
- Linux: Instructions
Feel free to upgrade it to give data through .txt or .dat file.
mpic++ name_searcher.cpp -o <executable-name>
mpiexec -n <number-of-nodes> <executable-name>
example: mpiexec -n 4 ./a.out
mpiexec -n <number-of-nodes> <executable-name> <random-array-size>
example: mpiexec -n 4 ./a.out 100000
