# simpleIPC - simpleIPC

## Description

This CUDA Runtime API sample is a very basic sample that demonstrates Inter Process Communication with one process per GPU for computation.  Requires Compute Capability 3.0 or higher and a Linux Operating System, or a Windows Operating System.

## Key Concepts

CUDA Systems Integration, Peer to Peer, InterProcess Communication
