OpenACC is a standard for parallel programming on accelerators, such as Nvidia GPUs and Intel Phi. It consists primarily of a set of compiler directives for executing code on the accelerator, in C and Fortran. OpenACC is currently only supported by the PGI compilers installed on OSC systems.
OpenMP is a standard for parallel programming on shared-memory systems, including multicore systems. It consists primarily of a set of compiler directives for sharing work among multiple threads. OpenMP is supported by all the Fortran, C, and C++ compilers installed on OSC systems.
OnDemand provides two related job managment tools: one allows you to create and submit jobs via your web browser, and the other allows you to monitor queued and running jobs.
Here is a tutorial video that gives an overview of OnDemand's Job client's capabilities and how to utilize them.
OnDemand provides a web-based File Explorer that can be used to upload and download files to your OSC home directory or project directory, and copy, delete, rename, and edit files.
There is a size limit for moving data of 10GB using ondemand file explorer, including transferring data between OSC and local storage, or moving the data from one OSC storage to another. It is recommended to use an sftp client, globus, or command line tool such as rsync for larger data transfers. Contact oschelp@osc.edu for questions and guidance.
Here is a tutorial video that gives a overview of OnDemand's file management client's capabilities and how to utilize them.
OnDemand is our "one-stop shop" for access to our High Performance Computing resources. With OnDemand, you can upload and download files; create, edit, submit, and monitor jobs; run GUI applications; and connect via SSH, all via a web broswer, with no client software to install and configure.
We've created a brief video explaining OnDemand's capabilities so users can better gauge if it is the right fit for them. Getting connected to OnDemand is also covered in this video. In addition, we've developed tutorial videos for OnDemand's job client and file management client.
Our HOWTO collection contains short tutorials that help you step through some of the common (but potentially confusing) tasks users may need to accomplish, that do not quite rise to the level of requiring more structured training materials. Items here may explain a procedure to follow, or present a "best practices" formula that we think may be helpful.

Gnuplot is a portable command-line driven data and function plotting utility. It was originally intended to allow scientists and students to visualize mathematical functions and data.
The Ohio Supercomputer Center provides services to clients from a variety of types of organizations. The methods for gaining access to the systems are different between Ohio academic institutions and everyone else.
