Ascend, Cardinal, Pitzer
MPI is a standard library for performing parallel processing using a distributed memory model. The Pitzer, Ascend, and Cardinal clusters at OSC can use the OpenMPI implementation of the Message Passing Interface (MPI).
Cardinal
ANSYS Workbench platform is the backbone for delivering a comprehensive and integrated simulation system to users. See ANSYS Workbench platform for more information.
Cardinal
ANSYS Mechanical is a finite element analysis (FEA) tool that enables you to analyze complex product architectures and solve difficult mechanical problems. You can use ANSYS Mechanical to simulate real world behavior of components and sub-systems, and customize it to test design variations quickly and accurately.

Connections to OSC
In order for users to access OSC resources through the web your firewall rules should allow for connections to the following publicly-facing IP ranges. Otherwise, users may be blocked or denied access to our services.
- 192.148.248.0/24
- 192.148.247.0/24
- 192.157.5.0/25
The followingg TCP ports should be opened:
OSC is refreshing the software stack on Ruby on September 15, 2015 (during the scheduled downtime). During the software refresh, some default versions are updated to be more up-to-date. Information about the old and new default versions, as well as all available versions of each software package will be included on the corresponding OSC software webpage. See https://www.osc.edu/supercomputing/software-list.
OSC is refreshing the software stack on Oakley on September 15, 2015 (during the scheduled downtime); something we have not done since Oakley entered service in 2012. During the software refresh, some default versions are updated to be more up-to-date and some older versions are removed. Information about the old and new default versions, as well as all available versions of each software package will be included on the corresponding OSC software webpage.
Memory Limit:
It is strongly suggested to consider the memory use to the available per-core memory when users request OSC resources for their jobs. On Oakley, it equates to 4GB/core and 48GB/node.
Memory Limit:
It is strongly suggested to consider the memory use to the available per-core memory when users request OSC resources for their jobs. On Glenn, it equates to 3GB/core and 24GB/node.
There are many instances where it is necessary to run the same serial program many times with slightly different input. Parametric runs such as these either end up running in a sequential fashion in a single batch job, or a batch job is submitted for each parameter that is varied (or somewhere in between.) One alternative to this is to allocate a number of nodes/processors to running a large number of serial processes for some period of time.
