Owens Information Transition

Owens cluster will be decommissioned on February 3, 2025. Some pages may still reference Owens after Owens is decommissioned , and we are in the process of gradually updating the content. Thank you for your patience during this transition

Ascend

SAMtools

SAM format is a generic format for storing large nucleotide sequence alignments. SAMtools provide various utilities for manipulating alignments in the SAM format, including sorting, merging, indexing and generating alignments in a per-position format.

Availability and Restrictions

The following versions of SAMtools are available on OSC clusters:

OpenMPI

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).

Software Refresh

OSC timely installs new software versions on OSC systems, and periodically do coordinated software refresh (update the default versions to be more up-to-date and remove some versions that are quite out of date) on OSC systems. While we encourage everyone to use up-to-date software, the old defaults will still be available till the next software refresh, in case some users prefer to use the old defaults. The software refresh is usually made during the scheduled downtime, while we will send out notifications to all users ahead of time for any questions/suggestions/concerns.

GNU Compilers

Fortran, C and C++ compilers produced by the GNU Project. 

Availability and Restrictions

Versions

The GNU Compiler Collection (GCC) are available on all our clusters. These are the versions currently available:

Boost

Boost is a set of C++ libraries that provide helpful data structures and numerous support functions in a wide range of aspects of programming, such as, image processing, gpu programming, concurrent programming, along with many algorithms.  Boost is portable and performs well on a wide variety of platforms.

HOWTO: Use ulimit command to set soft limits

This document shows you how to set soft limits using the ulimit command.

The ulimit command sets or reports user process resource limits. The default limits are defined and applied when a new user is added to the system. Limits are categorized as either soft or hard. With the ulimit command, you can change your soft limits for the current shell environment, up to the maximum set by the hard limits. You must have root user authority to change resource hard limits.

Training

OSC offers online and in-person training for new and advanced users on a variety of high performance supercomputing topics.

New! Online Training Courses

OSC has partnered with The Ohio State University to offer online training courses that clients can complete at their own pace at any time on the ScarletCanvas platform, Ohio State's public learning management system.

The first two available courses are:

Python

Python is a high-level, multi-paradigm programming language that is both easy to learn and useful in a wide variety of applications.  Python has a large standard library as well as a large number of third-party extensions, most of which are completely free and open source.
