| | 2 | With this method, you can submit MATLAB jobs from MATLAB running on an interactive session. See how to run MATLAB interactively [https://wiki.hpc.tulane.edu/trac/wiki/cypress/Matlab#RunningMATLABinteractively here]. |

| | 6 | === Configuration === |
| | 7 | Login to Cypress and start an interactive session and then start MATLAB (see [https://wiki.hpc.tulane.edu/trac/wiki/cypress/Matlab#RunningMATLABinteractively here]) |
| | 8 | Configure MATLAB to run parallel jobs on your cluster by calling '''configCluster''', which only needs to be called once per version of MATLAB. |
| | 9 | Please be aware that running '''configCluster''' more than once per version will reset your cluster profile back to default settings and erase any saved modifications to the profile. |
| | 10 | |
| | 11 | {{{ |
| | 12 | >> configCluster |
| | 13 | }}} |
| | 14 | |
| | 15 | Jobs will now default to the cluster rather than submit to the current node. |
| | 16 | |
| | 17 | When you encounter an error ''Unrecognized function or variable 'configCluster'. '', try |
| | 18 | |
| | 19 | {{{ |
| | 20 | >> rehash toolboxcache |
| | 21 | }}} |

| | 25 | == INTERACTIVE JOBS - MATLAB client on Cypress == |
| | 26 | Note this is for '''MATLAB client on Cypress'''. |
| | 27 | |
| | 28 | To run an interactive pool job on the cluster, continue to use parpool as you’ve done before. |
| | 29 | {{{ |
| | 30 | >> % Get a handle to the cluster |
| | 31 | >> c = parcluster; |
| | 32 | }}} |
| | 33 | {{{ |
| | 34 | >> % Open a pool of 4 workers on the cluster (works up to 12?) |
| | 35 | >> p = c.parpool(4); |
| | 36 | }}} |
| | 37 | Rather than running local on the local machine, the pool can now run across multiple nodes on the cluster. |
| | 38 | {{{ |
| | 39 | >> % Run a parfor over 1000 iterations |
| | 40 | >> parfor idx = 1:1000 |
| | 41 | a(idx) = idx |
| | 42 | end |
| | 43 | }}} |
| | 44 | Once we’re done with the pool, delete it. |
| | 45 | {{{ |
| | 46 | >> % Delete the pool |
| | 47 | >> p.delete |
| | 48 | }}} |
