Validator Hardware Requirements

Since the testnet is not intended for stress testing of max transaction throughput, a higher-end machine with a GPU is not necessary to participate.

However ensure the machine used is not behind a residential NAT to avoid NAT traversal issues. A cloud-hosted machine works best. Ensure that IP ports 8000 through 10000 are not blocked for Internet inbound and outbound traffic.

Prebuilt binaries are available for Linux x86_64 (Ubuntu 18.04 recommended). MacOS or WSL users may build from source.

Recommended Setups

For a performance testnet with many transactions we have some preliminary recommended setups:

GPU Requirements

CUDA is required to make use of the GPU on your system. The provided Solana release binaries are built on Ubuntu 18.04 with CUDA Toolkit 10.1 update 1". If your machine is using a different CUDA version then you will need to rebuild from source.
