Use this area to enter command-line arguments that your program will use when it begins executing. Type the arguments as one line within this control.
If you type arguments after your program has begun executing, these arguments are ignored until you restart it.
Enter environment variables to be used when you restart your program. Enter them one to a line and use the following format: variable=value.
If you type arguments after your program has begun executing, these arguments are ignored until you restart it.
Notice the LD_PRELOAD variable. This variable is set by MemoryScape and is what enables memory debugging. If you alter this command, you will not be able to perform memory debugging activities when you restart your program.

Enter the number of tasks or ranks that your program will use. This is the equivalent of the –np (number of processes) argument contained within many MPI systems.
Some MPI systems let you specify the number of nodes upon which your tasks will execute. For example, suppose your program will use sixteen tasks. If you specify four nodes, four tasks would execute on each node.
If you need to send other arguments to the MPI launcher, enter them here. These arguments are specific to the kind of MPI launcher you are using.
