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 2019
max date: current date (or other end date)
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
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.
OSC will be refreshing the software stack for Owens and Pitzer on May 19, 2020. This will be done in a system-wide downtime. During the software refresh, some default versions will be changed to be more up-to-date. Information about the new default versions, as well as all available versions of each software package will be included on the corresponding OSC software webpage.
An ACL (access control list) is a list of permissions associated with a file or directory. These permissions allow you to restrict access to a certain file or directory by user or group.
NetCDF (Network Common Data Form) is an interface for array-oriented data access and a library that provides an implementation of the interface. The netcdf library also defines a machine-independent format for representing scientific data. Together, the interface, library, and format support the creation, access, and sharing of scientific data.
For mpi-dependent codes, use the non-serial NetCDF module.
This document shows you how to use the POSIX ACL permissions system. An ACL (access control list) is a list of permissions associated with a file or directory. These permissions allow you to restrict access to a certian file or directory by user or group.
Understanding POSIX ACL
An example of a basic POSIX ACL would look like this:
Profile information can be changed by logging in with valid osc credentials to the OSC client portal and navigating to the profile page by clicking the display name in the upper right corner of the page and selecting Edit my profile.
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.
For mpi-dependent codes, use the non-serial HDF5 module.
