An early bird registration rate is available until March 2 for participants who register to attend the Linux Clusters Institute (LCI) Intermediate Workshop in Boulder March 23-27. The workshop will be held in the main auditorium at the Center Green campus (CG1). It is intended for those who have some experience in HPC system administration and want to expand their skills.

Participants in the five-day workshop will:

  • Strengthen their overall knowledge of HPC system administration

  • Focus in depth on file systems and storage, HPC networks, job schedulers, and Ceph

  • Get hands-on training and discuss real-life stories with experienced HPC administrators

Those who have attended an Introductory LCI workshop in the past are especially encouraged to attend. Visit the LCI web page for more information and a registration link. (Introductory and advanced LCI workshops will be held later in the year in Delaware and Washington, D.C.)

MathWorks is offering a free, one-hour training session at 11 a.m. MDT on Tuesday, March 10, to introduce the latest MATLAB interactive apps and tools for analyzing, visualizing, and exploring scientific data. Attendees will learn how to import data, define variables, and visualize data using prebuilt plots and visualization tools. The session will also explore documentation to find built-in functions, guidance on syntax, and code examples that demonstrate how to use the functions.

Highlights will include:

  • Import data and images from files, spreadsheets and other sources

  • Explore and visualize data using prebuilt plots and customize the visualizations

  • Create variables, customized algorithms and applications

Video and slides from the February 20 Globus tutorial are now available here in the CISL training library. The presentation by Brian Vanderwende of the CISL Consulting Services Group shows how to use the Globus service to transfer data quickly and reliably for storing files and sharing them with colleagues. 

Topics covered include:

  • Using the NCAR endpoints to move data between NCAR systems, external HPC platforms, and personal workstations

  • Introduction to the Globus web and command-line interfaces

  • Integrating Globus into users’ workflows using long-lived certificates and our gci utility

  • Sharing data with external collaborators via the NCAR Data Sharing Service

CISL’s User Services Section and Visualization & Analysis Systems Technologies group will host an OpenACC GPU programming workshop presented by XSEDE and the Pittsburgh Supercomputing Center on Tuesday, March 3, at the NCAR Mesa Lab’s Visualization Lab in Boulder. The workshop will begin at 9 a.m. MST and is scheduled to end at 3 p.m. The tentative agenda is provided below.

OpenACC is a directive-based standard for developing GPU-capable codes with standard languages and compilers in order to accelerate applications within short development periods. The workshop assumes participants have a working knowledge of either the C or Fortran programming languages. A hands-on component will use the Bridges computing platform at the Pittsburgh Supercomputing Center.

To attend, register by Friday, February 28, through the XSEDE User Portal. Space is limited.

The Cheyenne cluster will be unavailable beginning at 6 a.m. MST on Tuesday, February 25, to allow CISL staff and HPE engineers to perform critical infrastructure maintenance, repairs, and system software updates. The system is expected to be returned to service no later than Saturday evening, February 29. This will be Cheyenne’s last scheduled outage until the third quarter of this year.

A system reservation will prevent most batch jobs from executing after 6 a.m. Tuesday. Jobs and login sessions that are still running when the maintenance period begins will be killed. Cron also will not be available during the maintenance window.

The Casper cluster, GLADE and Campaign Storage file systems, data-access nodes, and HPSS will remain available throughout the week except for approximately four hours beginning at 8 p.m. MST on February 25 while a key network infrastructure component is rebooted. Users will be kept apprised of the effort throughout the week with updates in the CISL Daily Bulletin.

Researchers who need help visualizing data to demonstrate the results of their scientific computing can request expert assistance and collaboration from CISL. This service is available to researchers who want help using specialized applications on data analysis and visualization resources that CISL manages.

CISL visualization staff have particular expertise in CISL-developed software such as VAPOR and NCL but are open to assisting with other applications. They have helped science teams produce numerous visualizations for conferences, publications, and scientific journals as well as science and broadcast news programs.

See Advanced visualization support to learn how to submit a request, what criteria must be met, and other details.
