Can't find GPU in LAN

I have some GPUs mounted on a machine which is part of a cluster, in a Local Area Network. However, after opening a matlabpool involving the machine the GPUs are mounted on, MATLAB (v 2013a) doesn't see them.
In fact gpuDevice returns an error saying
"The CUDA driver could non be loaded [...]". But I can't install the CUDA driver on the machine I'm running MATLAB from, because the installation fails, as there is no GPU in this machine, they are in the LAN.
Any help? Luca

You need to install the CUDA driver on the worker machines. Once this is done, you should be able to use gpuArray and gpuDevice within PARFOR loops and SPMD blocks - but you will not be able to return gpuArray data back to the host, you must GATHER it before it returns.
