Here are the BRPS apps with corresponding server names:

Binary Radio Pulsar Search (Arecibo) BRP4
Binary Radio Pulsar Search (Arecibo, GPU) BRP4G
Binary Radio Pulsar Search (Perseus Arm Survey) BRP5

I'm currently crunching Binary Radio Pulsar Search (Arecibo) on an Intel GPU. As far as I know, there are no BRPS CPU apps.
