You can explore GPU computing through Matlab if you think your program can benefit from massively parallel computations:
MATLAB GPU Computing Support for NVIDIA CUDA-Enabled GPUs
Finally, parallel computing features like parfor and spmd can be used by launching a pool of workers on a node.
Note that the Parallel Computing Toolbox by itself cannot span across multiple nodes, so make sure you request only 1 node to avoid wasting resources.
