The Ohio Supercomputer Center (OSC) is experiencing an email delivery problem with several types of messages from MyOSC. 

 OSC is preparing to update Slurm on its production systems to version 23.11.4 on March, 27.

OSC has recently switched schedulers from PBS to Slurm.
Please see the slurm migration pages for information about how to convert commands.

Batch processing

Efficiently using computing resources at OSC requires using the batch processing system. Batch processing refers to submitting requests to the system to use computing resources.

HDF5 is a general purpose library and file format for storing scientific data. HDF5 can store two primary objects: datasets and groups. A dataset is essentially a multidimensional array of data elements, and a group is a structure for organizing objects in an HDF5 file. Using these two basic objects, one can create and store almost any kind of scientific data structure, such as images, arrays of vectors, and structured and unstructured grids.

GROMACS is a versatile package of molecular dynamics simulation programs. It is primarily designed for biochemical molecules, but it has also been used on non-biological systems.  GROMACS generally scales well on OSC platforms. Starting with version 4.6 GROMACS includes GPU acceleration.

The only access to significant resources on the HPC machines is through the batch process.

TIP: Remember to check the menu to the right of the page for related pages with more information about Oakley's specifics.
OSC plans to decommission Oakley by the end of 2018. Nodes on Oakley in bad service states are being removed from service, resulting in a slightly reduced capacity.

Oakley is an HP-built, Intel® Xeon® processor-based supercomputer, featuring more cores (8,328) on half as many nodes (694) as the center’s former flagship system, the IBM Opteron 1350 Glenn Cluster. The Oakley Cluster can achieve 88 teraflops, tech-speak for performing 88 trillion floating point operations per second, or, with acceleration from 128 NVIDIA® Tesla graphic processing units (GPUs), a total peak performance of just over 154 teraflops.

The Ohio Supercomputer Center's IBM Cluster 1350, named "Glenn", features AMD Opteron multi-core technologies. The system offers a peak performance of more than 54 trillion floating point operations per second and a variety of memory and processor configurations. The current Glenn Phase II components were installed and deployed in 2009, while the earlier phase of Glenn – now decommissioned – had been installed and deployed in 2007.

We currently operate three major systems:

License problems

If you get a license error when you try to run a third-party software application, it means either the licenses are all in use or you’re not on the access list for the license. Very rarely there could be a problem with the license server. You should read the software page for the application you’re trying to use and make sure you’ve complied with all the procedures and are correctly requesting the license. Contact OSC Help with any questions.
