Quick Instructions for Hopper users

Please run jobs as the same way you do on Hopper, just keeping in mind that Edison compute nodes have 16 cores per node (vs Hopper's 24). In addition, you have an option to run 2 threads or 2 tasks per physical core through the Intel's Hyper-threading (HT) technology, which makes each physical core apear as two logical cores. Using HT, Edison has 32 cores per node. To use HT, you need to use the "-j 2" option for the aprun command. Please see more details in the following sections.
