The CISL Consulting Services Group will offer its four-day High Performance Computing (HPC) workshops on May 22 to 25, 2012, to help our users learn essential knowledge and skills to work with supercomputers. Topics include CISL Facilities and Support Overview, UNIX, Fortran, Programmer’s Tools, Parallel Programming with MPI/OpenMP, NCL/IDL/Matlab, and others.

You can enroll in the workshop either on-site or online. Please visit the following link for more details and registration.

While CISL is preparing for the arrival of the first Yellowstone hardware shipments, we wanted to provide users with some information about what you can expect from Bluefire in the coming months.

Most important, CISL has extended the maintenance agreement for Bluefire through September 30, 2012, and we will continue to operate Bluefire as a production resource until that date. If you encounter any issues, please contact cislhelp@ucar.edu as you do now.

Keep the September 30 deadline in mind, however. On or shortly after that date, Bluefire will be shut down for good. We will not be able to keep Bluefire around for "one last run." All users and projects should plan to complete critical work or reach meaningful stopping points before that date.

Furthermore, keep in mind that Bluefire is likely to become more active near the deadline, not less busy, as users try to complete their projects. All users are asked to plan accordingly and avoid the last-minute rush.

For planning purposes, assume that the September 30, 2012, is fixed. However, CISL is closely watching the Yellowstone deployment schedule for any changes that would recommend an extension to Bluefire's operation. We will inform users as quickly as possible if we change the date.

Making sure that we can reach you when necessary can help you avoid being locked out of the system. Say a job that you’re running on Bluefire is causing problems and we can’t contact you because your phone number or email address has changed. As explained on our User responsibilities page, that job may be killed and you will find yourself locked out. If your name, phone number, email address, or other information changes, please promptly notify the CISL Help Desk by email.

Location: VisLab at the NCAR Mesa Lab, 1850 Table Mesa Drive, Boulder, CO

Globus Online is a convenient interface for transferring files between two endpoints – for example, between NCAR resources and XSEDE facilities or other sites. Globus Online also offers a feature called Globus Connect, which enables you to move files easily to and from your laptop or desktop computer and other endpoints.

The CISL Consulting Services Group will conduct an hour-long workshop on Wednesday, April 25, to help you set up and work with Globus Online. You are encouraged to bring your own laptop for practice. The workshop will also be available online through the following link for those who can't attend in person.

Please contact cislhelp@ucar.edu if you have any questions or concerns.

On Saturday, April 14 2012, the NCAR/CISL Data Center will be shut down for preventative maintenance on select infrastructure support systems. This is the normal Spring season down time for this purpose. Please note this activity is a complete shutdown with some minor exceptions listed below, scheduled for 6 a.m. to 6 p.m. Mountain Time.

The supercomputer systems will begin their shut down at 12:01 a.m. Mountain Time, and some computing systems, depending on their function, will begin their shutdown Friday afternoon/evening. Please make arrangements accordingly.

Once all maintenance work is completed, the systems will be brought back up in their order of dependency. CISL and Facilities Management and Sustainability maintain the twelve hour window to accomplish all tasks at hand.

Basic networking for phone service will be available for the Mesa Lab during most of this maintenance window, however, intermittent outages may occur.

For more information, contact CISL Help Desk at cislhelp@ucar.edu or 303-497-2400.

Best Practice: Periodically examine your HPSS holdings and remove unwanted, unneeded files. This reduces your GAU charges and makes the HPSS system more efficient for everyone.
For more on how to make the most of your computing and storage allocations, please see CISL best practices.

April 12, 2012

Check your GAU usage frequently to help ensure that you are using NCAR resources as efficiently as possible. Understand how your choice of queues affects charges against your allocation, and be aware of other allocation-related policies. See Allocation management.

CISL now supports file transfers using the Globus Online interface, which simplifies and speeds the movement of data between CISL-managed resources and XSEDE facilities or other sites. The service also provides a feature called Globus Connect for easy transfers to and from laptop or desktop computers and other endpoints. For details, see our Globus Online documentation.
