Hi, I have two computers with cuda enable gpus when I run "gpuArray" locally, it workes well but when I run it in SPMD statement on 2 computers it shows this error: " No device supporting CUDA was found." if I want to have a cluster of GPUs what can I do? Thanks

OS:64 bit Win7
GPU:GeForce GT 430
Driver:285.62-desktop-win7-64bit
scheduler:Jobmanager
Is it possible to use a GPU command in spmd on cluster?

This should work, since it looks like that card supports TCC mode.
You can check (and change) this with the nvidia-smi utility, which should be in with the files that came with the driver in a directory called "NVSMI"

Yes, that looks to be the case with this card on Windows:

Hi,
the doc says the following:
Access from a MATLAB worker running on a Microsoft Windows operating system with a job manager as the scheduler, requires an NVIDIA Tesla Compute Cluster (TCC) driver with an NVIDIA Tesla card.
