# p2pBandwidthLatencyTest - Peer-to-Peer Bandwidth Latency Test with Multi-GPUs
|
|
|
|
## Description
|
|
|
|
This application demonstrates the CUDA Peer-To-Peer (P2P) data transfers between pairs of GPUs and computes latency and bandwidth. Tests on GPU pairs using P2P and without P2P are tested.
|
|
|
|
## Key Concepts
|
|
|
|
Performance Strategies, Asynchronous Data Transfers, Unified Virtual Address Space, Peer to Peer Data Transfers, Multi-GPU
|
|
|
|
