There are a few things to make a cluster using multiple machines.
- You need to install MDCS (MATLAB Distributed Computing Server) on each machine. This is a different license than Parallel Computing Toolbox. There is a more detailed installation guide here.
- A cluster needs a correctly configured network to be able to run. Name resolution of cluster hosts, the correct open ports, etc. We ship a tool called Admin Center which can help you set up and run a cluster, and it includes diagnostic tools to check that hosts are configured correctly.
- Installation help and support is available for MDCS. Contact support directly, they are there to help.
In order to use the GPU, it depends on your operating system and nVidia driver.
- On Linux you can install the driver and the workers will be able to utilize the GPU.
- On Windows the driver needs to be able to be put into TCC mode for workers to access the GPU. There are some restrictions on which cards can be put into this mode -- some are put in place by the driver, and if you are driving a display with the GPU it will not be accessible.
- The documentation for nvidia-smi can be found on nVidia's website or within the utility itself (--help).
- On Linux, it's generally on the path, and on Windows it's in C:\Program Files\Nvidia Corporation\NVSMI\nvidia-smi.exe.
