I'm wondering if its possible to somehow present the user with a param that lets him
or her specify number of cores, nodes, memory, and wall time from within the workflow for
a specific tool.
Other than coming up with a predictive algorithm for each tool's resource needs
(memory especially) how is one supposed to efficiently use Galaxy and PBS other than
somehow letting the user specify needed resources? Think in cases like assembly, for
example with Velvet depending on the input files, resource requirements can be vastly
different job to job.
