Maximum virtual image size, in kilobytes, to which your program will grow during execution. LoadLeveler tries to execute your job steps on a machine that has enough resources to support executing and checkpointing your job step. If your job command file has multiple job steps, the job steps will not necessarily run on the same machine, unless you explicitly request that they do.
If you do not specify the image size of your job command file, the image size is that of the executable. If you underestimate the image size of your job step, your job step may crash due to the inability to acquire more address space. If you overestimate the image size, LoadLeveler may have difficulty finding machines that have the required resources.
The syntax is:
image_size = number
Where number must be a positive integer. For example, to set an image size of 11 KB, the keyword statement would be:
image_size = 11
