 Parallel Computing with MATLAB – 3/25/2021 at 10 AM

Using the Parallel Computing capabilities in MATLAB allows users to take advantage of additional hardware resources that may be available either locally on their desktop or on clusters, clouds, and grids. By using more hardware, you can reduce the cycle time for your workflow and solve computationally and data-intensive problems faster.  This webinar discussed a range of workflows available to scale MATLAB applications with minimal changes to your MATLAB code and without needing to learn low-level programming. Below are some of the highlights discussed:

• Leveraging multiple cores or CPUs
• Working with high-level constructs—parallel for-loops, special array types, and parallelized numerical algorithms.
• Scaling up to utilize clusters, grids, and clouds
• Utilizing tall and distributed arrays to work with large data sets
• Using MATLAB for GPU computing

 NOTE: MATLAB is accessible on WUIT’s RIS compute cluster. You can request access to RIS compute and storage to leverage MATLAB, to do so, use your WUSTL key to log in here (All WashU Faculty have access to 5TB of free storage available to them). Please visit the RIS website to learn more.
