Task Parallel Application - The same application that runs independently on several nodes, possibly with different input parameters. There is no communication, shared data, or synchronization points between the nodes.
Data Parallel Application - The same application that runs on several labs simultaneously, with communication, shared data, or synchronization points between the labs.
Lab - A MATLAB worker in a multicore (Data Parallel) job. One lab is assigned to one worker (core). Thus, a job with eight labs has eight processor cores allocated to it and will have eight workers each working together as peers.
MDCS - MATLAB Distributed Compute Server. This is a component of MATLAB that allows our clusters to run MATLAB jobs that exceed the size of a single compute node (multinode parallel jobs). It also allows jobs to run even if there are not enough toolbox licenses available for a particular toolbox, so long as the university owns at least one license for the particular toolbox.
PCT - Parallel Computing Toolbox.
MATLAB Task - One segment of a job to be evaluated by a worker.
MATLAB Job - The complete large-scale operation to perform in MATLAB, composed of a set of tasks.
MATLAB Worker - The MATLAB session that performs the task computations. If a job needs eight processor cores, then it must have eight workers.
Job - Job submitted via the SLURM job scheduler (also called SLURM Job).
