Overview
The main point of using lonestar6 is that it is a massive computer cluster. If we run a command when logged into lonestar6, we are running it on one of the three low memory, low power "head" or "login" nodes on TACC. When we do serious computations that are going to take more than a few minutes or use a lot of RAM, we need to submit them to one of the other 560 computer nodes and 71, 680 processor cores on lonestar6.

Wayness sets how many commands/tasks are run on each compute node. By default, wayness will be 128 64 (equal to the number of physical cores per node on stampede2lonestar6). Each task will then get 1/64th of the memory available for one node (256 GB of memory) = 4 GB per task. Often, that is not enough memory per task or you may not even have 64 tasks in your commands file. Setting wayness to a number smaller than the default will allocate more memory per task.
