-<p>We use shark to connect COR@L Lab outside of campus. Only two servers in COR@L Lab can be reached outside of campus, coral and shark. Working on shark is not recommended, it lacks the basic software available on other servers (compilers, mathematical and optimization software, etc.).</p>+<p>Shark server manages various software licenses including AMPL license.</p>

 <p>Polyps is COR@L Lab’s cluster composed of 16 nodes (polyp1-polyp15, polyp30). It is our heavy duty cluster. Polyps has <a href="http://www.adaptivecomputing.com/products/torque" target="_parent">Torque</a> installed as a job scheduler. Torque aims to maximize resource utilization and high throughput by scheduling jobs submitted by users and allocating resources (CPU, memory) of Polyps to them. For a brief introudction to Torque see Software section. Long lasting experiments should be submitted to polyps through Torque. You can also check the load of Polyp nodes from <a href="http://polyps.ie.lehigh.edu/ganglia" target="_parent">ganglia</a> web interface.</p> <p>Polyps is COR@L Lab’s cluster composed of 16 nodes (polyp1-polyp15, polyp30).

 <li>There are two restrictions on processes in polyp1. First restriction is that a process is allowed to run only for 300 CPU time minutes. The second one is a process can use at most 10 Gb of memory. All long lasting experiments should be conducted through condor. You can see some guiding examples at directory “/scratch/coral_introduction” in polyp1. There are no restrictions in polyp2-12, they are only bounded by the hardware installed.</li> <li>There are two restrictions on processes in polyp1.
