Overview

Slurm, which stands for Simple Linux Utility for Resource Management, is a widely used open-source HPC resource management and scheduling system that originated at Lawrence Livermore National Laboratory.

Ohio academics should visit the fee structure page for pricing information.
All others should contact OSC Sales for pricing information.
If there are questions/concerns on charging at OSC, please contact OSC Help.

Job charging based on usage

OSC offers the use of budgets to limit the amount of charges incurred on projects.

Active budget

Once a budget has been approved, it (and the project it was requested from) becomes active. Having an active project allows users on that project to submit batch jobs to use OSC resources.

PETSc is a suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations. It supports MPI, and GPUs through CUDA or OpenCL, as well as hybrid MPI-GPU parallelism.

It is useful to take a look at usage over periods of time and calculate overall usage at osc. This page explains how to do this using the HPC Job Activity tool in my.osc.edu

After logging into the client portal, navigate to Individual -> HPC Job Activity.

Enter the appropriate dates:

min date: 01 July 2020
max date: current date (or other end date)

There are different requirements for being able to charge OSC usage towards a grant. This page aims to provide general guidelines, but actual requirements may be different. Contact OSC help if there are specific questions/needs.

Address Sanitizer is a tool developed by Google detect memory access error such as use-after-free and memory leaks. It is built into GCC versions >= 4.8 and can be used on both C and C++ codes. Address Sanitizer uses runtime instrumentation to track memory allocations, which mean you must build your code with Address Sanitizer to take advantage of it's features.

It is possible to utilize Cron and the OSCusage command to send regular usage reports via email

Cron

It is easy to create Cron jobs on the Owens and Pitzer clusters at OSC. Cron is a Linux utility which allows the user to schedule a command or script to run automatically at a specific date and time. A cron job is the task that is scheduled.
