Central processing units (CPU) and cores: A core is the basic computation unit of the CPU. At the hardware level, a CPU consists of one or more cores where each core is a processing unit. Increasing cores enables more jobs to run simultaneously and significantly increases work completed. At the software level, there is no distinction between CPUs and cores, therefore, the total number of cores is reported as the number of CPUs. This is the case with Partek Flow as all references to CPU counts are the total number of CPU cores in the computer.

Gene Specific Analysis (GSA): Partek developed method to identify the statistical model that is best for a specific gene among all the selected models, then using that model to calculate pvalue and fold change.

Head node: The controlling computer in a compute cluster. The job scheduler and Partek Flow server are both installed on the head node and accessible to users. In most cases, jobs are not processed on the head node, but on the compute nodes.
