XSEDE is a set of national computing resources that researcher can apply for. It is one in a set of national resources that powers a large share of national resources including DOE, Blue Waters, and others.
Currently it is very difficult to combine the two sets of resources. MATLAB is commercial and getting access to a license that you can use on XSEDE can be problematic due to license cost and technical complexity.
MCC - The MATLAB Compiler
MCC (Flux Docs) is a toolbox/add-on to MATLAB that allows the wrapping of mcode into a standalone executable. Features of this executable is that it can be ran anywhere using any functionality that was available at the site it was compiled at. Thus MATLAB programs can be moved to a resource such as XSEDE within your license terms.
The downsides are you cannot modify your mcode on the XSEDE resource. You have to make any design changes where you have your MATLAB license and MCC license. This limitation can be mitigated by the fact that MCC can compile functions and arguments can be passed on the command line. Of course MCC compiled code can also read from files that regular MATLAB can. So if your code is stable but you are running different inputs that is no problem.
This is will be in two parts. What needs to be done on Flux or other machine with MATLAB and MCC installed, and what needs to be done to run the result on the XSEDE resource. In this example I am going to use Stampede at TACC.
The example code is implicitthreads.m which solves a system of equations using the \ operator in MATLAB. It is implemented as a function, taking the number of unknowns.
