The Center for Research Computing (CRC) supports leading-edge research with free access to advanced computing hardware and software for fields across the entire research community, along with training and consultation by CRC research faculty. CRC offers the following services:

For the most up-to-date overview of the available compute hardware, see our Cluster Hardware Overview page.

The CRC compute resources can be split into the following categories:

clusters

Below is a schematic of all the key parts of the advanced computing infrastructure.

These systems are typically composed of one or more communal "log-in" servers that enable access to large "clusters" of computers with specialized hardware equipped for throughput/compute intensive data processing tasks.

User Clients

Starting on the left, a connection starts with the users' computer. This is the "local" client/machine. You start here, but the processing you want to run would quickly exhaust your individual systems resources, even if you've equipped it with high-end components. To deal with this, you'll connect to the CRC's clusters.

Firewalled Connection

Regardless of whether you're on campus, the next step is establishing a secure connection is required. If you're on a university administered workstation, this may be covered by your log-in and a physical connection to PittNet via an ethernet cable. If not, you will need to connect via Pitt's VPN.

Login Nodes

The next step is a remote login server. The CRC's main login servers are

Management Nodes

Once on the login node, the only thing between you and access to a compute-node is the job management system. This system attempts to queue jobs submitted by the many users sharing the login nodes in a fashion that is efficient and also fair.

Compute Nodes

These machines are where your job actually runs

The best way to get help on a specific issue is to submit a help ticket. You should log in to the CRC website using your Pitt credentials first.
