Primen
Primen is an educational software that implements prime factorization (using trial division) with distributed computing (using MPI.NET) and parallel computing (using System.Threading.Tasks).
For instance Primen can factorize a product of two prime numbers in order to obtain an RSA private key from a public key.
How to use it
Before using it, you need to install:
- Windows HPC Server 2008.
- MPI.NET Runtime in production or MPI.NET SDK for development.
Then download the latest Primen release from https://github.com/Davide95/Primen/releases, unzip it and start smpd on each machine typing
smpd -dAfterwards run
mpiexec -hosts N machine1 machine2 machineN 'C:\directory\where\it\was\unzipped\Primen.exe'on one of the machines.
For example, if you have 2 hosts called mOne and mTwo and the directory where you unzipped Primen is "C:\Primen", you have to type
mpiexec -hosts 2 mOne mTwo C:\Primen\Primen.exeHow to test it
Open a PowerShell window, go to the bin/Debug folder in Primen's project and run
.\Scripts\debug.ps1Benchmark
I ran this software on 24 PCs connected to eatch other through a switch in a classic LAN. They factorized 4951760154835678088235319297 (94 bits) in about 5 minutes.
