Fiscal Year 2021 Quarterly Allocation Reductions

March 3, 2021

You may have noticed that NREL did not make any reductions to allocations that were under-using their AUs during Q1.   This is for two reasons.   First, we were in the process of putting together a new, more transparent, fairer allocation reduction policy.  Second, we are aware that many users were inconvenienced by the fact that allocation decisions were issued on October 1.
 
We realize allocation reductions for low use are not popular with our users.  However, they are physically necessary.   AUs are an “expiring resource.”   If an AU is not used in Q1, it cannot be stored and saved for use in Q4.   Because of this, we have to remove some percentage of the unused AUs every quarter.  Otherwise we can hit a situation where we have many more AUs available to users than the machine can physically provide as the year progresses.   This creates long queue times that make Eagle physically unusable.
 
Our new allocation policy is given below.   We had an informal discussion with users across multiple centers before designing this policy.  Users emphasized the need for a policy to be clear enough so they could see what they might lose at the end of the quarter.   Users have also increasingly requested allocations that had different usages in different quarters to deal with their project needs, and we wanted a policy that treated these fairly.

Elevate your work with new tracking for Advanced Computing in the NREL Publishing Tracker

March 3, 2021

There is a new question on the User Facilities & Program Areas page when you enter a publication into the Pub Tracker – “The High Performance Computing Facility was used to produce results or data used in this publication.” Please be sure to check Yes on this question for your work that made use of the HPC User Facility or other systems in the ESIF HPC Data Center. In addition, there are three new Program Areas to use to tag your publication under the Advanced Computing heading: Cloud, HPC and Visualization & Insight Center. Making use of these metadata will enable us to elevate your work through communications highlights, feature stories, and reporting to EERE.

More information about the NREL Publishing Tracker can be found by visiting the Access and Use the NREL Publishing Tracker page on the Source.

Eagle Outage March 2nd

Feb. 1, 2021

Eagle will be taking an outage on March 2nd. We will be making time critical hardware repairs to the Lustre file system and doing some security patching. Small tweaks are being made to slurm to reduce the amount of advertised memory and reduce the number of E-cells jobs run on. Both should make nodes and jobs more reliable and increase performance for larger jobs. Continue reading

Jupyterhub Documentation

Feb. 1, 2021

We have written up a how-to guide for using the Europa Jupyterhub server, including setting up custom Python, Julia, and R kernels and interacting with Eagle. See https://www.nrel.gov/hpc/jupyterhub.html for more. Continue reading

Application Updates

Feb. 1, 2021

  • Q-Chem has been upgraded to version 5.3.2. See changes here.
  • Star-CCM version 15.06.008 is available on Eagle.
  • ARM Forge version 20.2 is available on Eagle.
  • We are working on acquiring a Maintenance license for VASP 6. Once we have this in place, users will need to have an upgraded VASP 6 Research workgroup license in order to use our VASP 6 builds on Eagle.

Lustre Quotas

Nov. 3, 2020

Effective with the new Fiscal Year 2021 Project allocations for Eagle, quotas for approved storage allocations' capacities have been implemented on /projects and MSS on Eagle. This was to encourage users to manage their /projects data usage and usage of /scratch for jobs. HPC Operations is developing reporting capabilities of usage, but in the mean time, users may request help from the HPC Help Desk, or utilize these procedures from an Eagle Login node: Continue reading
