Batch Limit Rules

Pitzer includes two types of processors, Intel® Xeon® 'Skylake' processor and Intel® Xeon® 'Cascade Lake' processor. This document provides you information on how to request resources based on the requirements of # of cores, memory, etc despite the heterogeneous nature of the Pitzer cluster. Therefore, in some cases, your job can land on either type of processor. Please check guidance on requesting resources on pitzer for your job to obtain a certain type of processor on Pitzer.
