The SCC is a fantastic pathway for undergraduates to prepare for a career in HPC as teams of students design, build and operate a small HPC cluster in a 48-hour competition at the annual Supercomputing conference. The IndySCC is its education-focused counterpart, in which teams learn to run scientific applications on provided HPC hardware, during the months leading up to SC24. Applications are due May 15, 2024. ### IDEAS HPC Best Practices Webinar on System Testing of Scientific Software on May 15 <a name="hpcbpwebinar"/></a> The IDEAS Productivity project is hosting an upcoming webinar in their HPC Best Practices Series, entitled "Getting it Right: System Testing of Scientific Software" on May 15, from 10-11 am (Pacific Time). Abstract: Testing software to ensure its correctness is a challenging yet critical task that can consume more than 50% of the software lifecycle. Over the past decade, we have built software testing practices into our development frameworks and are embracing the use of unit tests and continuous integration–testing as we code. However, these types of tests focus heavily on covering individual code elements and may miss important system-level requirements. In scientific software, we often model complex behaviors, and our applications are heavily data-driven and configurable. In addition, we have added machine learning components into this mix. Together, this situation can leave our systems vulnerable to subtle, incorrect behaviors, which can impact our scientific results. In this talk, I will discuss system testing for scientific software, present some challenges, such as configurability, and present some techniques we can use to help improve the testing process. Presenter: Myra Cohen (Iowa State University) Participation is free, but registration is required. For more information and to register, please see the [event webpage](https://ideas-productivity.org/events/hpcbp-083-gettingitright). ([back to top](#top)) --- ## Perlmutter <a name="section3"/></a> ## ### Perlmutter Machine Status <a name="perlmutter"/></a> Perlmutter is available to all users with an active NERSC account. Some helpful NERSC pages for Perlmutter users: * [Perlmutter queue information](https://docs.nersc.gov/jobs/policy/#qos-limits-and-charge) * [Timeline of major changes](https://docs.nersc.gov/systems/perlmutter/timeline/) * [Current known issues](https://docs.nersc.gov/current/#perlmutter) This section of the newsletter will be updated regularly with the latest Perlmutter status. ### Remote Possibility of File System Data Corruption Due to Slingshot Network Driver Bug <a name="datacorruption"/></a> NERSC was made aware of possible data corruption due to a bug in an underlying slinghot network driver that would cause corruption in files transmitted across the Perlmutter network to be written onto file systems. The bug was originally believed to only impact Perlmutter scratch, but we recently learned that it also affects file systems served by DVS (which is the way that the global homes, global common, and community file systems are interfaced with Perlmutter compute nodes). Data access via the Perlmutter login nodes or the DTNs is not affected as these do not use DVS. To guard against the bug, we enabled checksums on Perlmutter scratch in mid-November last year. During last week's maintenance, we migrated our DVS servers to use an alternative network protocol. Both these changes come with a performance penalty; for the Perlmutter scratch file system we saw a 17% penalty for large-scale I/O. We do not yet have a definitive number for the DVS-served file systems, but performance has definitely experienced an adverse impact, which we hope to partially mitigate with improvements to tuning. The corruption error appears to be quite rare; in the five months since checksums were enabled on Perlmutter scratch, there have been only two instances where data retransmissions occurred because of checksum mismatches. If you have any concerns about the integrity of your data, you would want to perform an md5sum data check against a good known copy of any file that was written to the following file systems within the following dates: - Perlmutter scratch: July 11, 2022 - November 16, 2023 - Global Homes, Global Common, CFS, DNA: July 11, 2022 - April 17, 2024 Please feel free to send in any questions via the [NERSC Help Desk](https://help.nersc.gov/). ([back to top](#top)) --- ## NERSC@50 <a name="section4"/></a> ## ### Save the Date: Celebrate 50 Years of NERSC with Us October 22-24 <a name="nug50"/></a> In honor of NERSC's fiftieth anniversary, we are planning an exciting program of anniversary-related events culminating with the annual NERSC User Group meeting, to be held October 22-24, 2024. Please join us to enjoy blasts from the past as well as fun in the future during this one-of-a-kind event! ### Read about NERSC History <a name="nerscfirsts"/></a> NERSC history experts are publishing articles and timelines in celebration of NERSC's golden anniversary.

The [next presentation](https://www.nersc.gov/news-publications/nersc-news/nersc50/nersc50-seminar-welcomes-manos-mavrikakis-may-20/) will take place next Monday, May 20 at 1:30 pm (Pacific time), and will feature Manos Mavrikakis, the Ernest Micek Distinguished Chair, James A. Dumesic Professor, and Vilas Distinguished Achievement Professor at the University of Wisconsin-Madison (and NERSC user for more than 24 years). Title: Reaction-driven formation of novel active sites on catalytic surfaces Abstract: Adsorption of reactants and reaction intermediates on solid catalytic surfaces can lead to significant changes of the surface structure, including, as shown in high-pressure Scanning Tunneling Microscopy (STM) experiments, ejection of metal atoms and formation of metal clusters while the reaction is taking place. Depending on the specific system, these clusters provide new, more favorable reaction paths than the typically considered active sites. First-principles computations coupled with kinetic Monte Carlo simulations, all performed at large scale on NERSC resources, enable a more realistic picture of the catalyst’s surface and its active sites as a function of reaction conditions and the identity of reactants and that of key intermediates. Insights derived from our analysis can inform the design of new catalysts with improved activity, selectivity, and stability characteristics. Additional talks will be posted on the [seminar series webpage](https://www.nersc.gov/events/nersc50-seminars) as speakers are confirmed. For more information on the series (including connection info), please see <https://www.nersc.gov/events/nersc50-seminars>. ([back to top](#top)) --- ## NERSC Updates <a name="section5"/></a> ## ### File Upload Service Retiring June 30 <a name="fileupload"/></a> Receiving a file from a collaborator who is not a NERSC user can occasionally present a challenge, though new tools have arisen to address this issue in recent years. NERSC has historically provided an FTP-based file upload service, but we are planning to retire that service as of June 30. We are considering options to replace it, but current constraints on staff effort mean that users may need to coordinate file transfers with non-user collaborators on their own. Following are some approaches that may be helpful in coordinating a data transfer, based on how large the files are. For smallish files (<100s of GBs), your collaborator can - Send as an email attachment - Transfer via a common server for which they and you have logins using scp, sftp, or rsync - Share via a cloud storage provider that you both use, such as Box, DropBox, Google Drive, Apple iCloud, or Microsoft OneDrive - Share via file transfer service such as WeTransfer or DropSend - Post world-readable on a web server somewhere and send you the URL - Send you a physical USB thumb drive or CD/DVD - Sign up for a NERSC account and get added to your project - Use a file sharing service at their or your home institution For largish files (100s of GBs or more), your collaborator can - Transfer via a common server for which they and you have logins, using bbcp or gridftp - Share via a cloud storage provider that you both use such as Amazon S3 bucket, Google Cloud Platform, or Microsoft Azure Blob - Share via paid-plan file transfer service such as WeTransfer, FileMail, or MyAirBridge - Post in a world-readable Globus collection and send you the collection identifier - Sign up for a NERSC account and get added to your project - Use a file sharing service at their or your home institution ### New Form for Requesting an Increase in Computing Time <a name="allocreq"/></a> Increases in a project's compute time require the approval of the appropriate DOE allocation manager(s), and there have been cases where due to mistakes in the process, a request was unnecessarily delayed or not awarded. To streamline the process, NERSC has created a new online form, the [Computing Time Increase Request form](https://nersc.servicenowservices.com/nav_to.do?uri=%2Fcom.glideapp.servicecatalog_cat_item_view.do%3Fv%3D1%26sysparm_id%3D9fe625d18768ca10519b0e950cbb35a3%26sysparm_link_parent%3De15706fc0a0a0aa7007fc21e1ab70c2f%26sysparm_catalog%3De0d08b13c3330100c8b837659bba8fb4%26sysparm_catalog_view%3Dcatalog_default%26sysparm_view%3Dtext_search) (login required), which standardizes the information requested and automatically generates a request that goes to the appropriate allocation manager(s). If your project runs low on time, the project PI, or one of their proxies, may request additional time by submitting the [Computing Time Increase Request form](https://nersc.servicenowservices.com/nav_to.do?uri=%2Fcom.glideapp.servicecatalog_cat_item_view.do%3Fv%3D1%26sysparm_id%3D9fe625d18768ca10519b0e950cbb35a3%26sysparm_link_parent%3De15706fc0a0a0aa7007fc21e1ab70c2f%26sysparm_catalog%3De0d08b13c3330100c8b837659bba8fb4%26sysparm_catalog_view%3Dcatalog_default%26sysparm_view%3Dtext_search). To access the form, log into the NERSC Help Desk at <https://help.nersc.gov>, and click the "Open Request" icon, then select the Computing Time Increase Request from the Request Forms menu. Fill in the form with the project, type of node hours requested (CPU or GPU), number of node hours, and a justification for the additional time being requested. WHen you submit the form, it will be assigned to the appropriate DOE allocation manager to review and provide the additional time.

In this workshop, Dr. Richard will lead discussions around multiproject CI/CD. As software organizations develop more CI/CD workflows, the effort required to maintain them grows. With the increase in modular software, it is anticipated that organizations will find themselves managing CI/CD for an ever growing number of projects. Since these projects are developed by the same organization, these workflows tend to have common needs that can be addressed by common solutions. The purpose of this workshop is to bring together CI/CD maintainers in order to identify challenges and share potential solutions for multiproject CI/CD. Submissions: The organizers welcome contributions in two forms: Contributed presentation, or Request for Information. Participants are welcome to contribute both a presentation and to answer the request for information. If you are interested in contributing a presentation, simply provide an abstract when registering. Depending on the number of abstracts received the organizers may need to down select. **Submissions are due May 29, 2024**. Participants whose abstracts are selected for presentations will be notified by May 30, 2024.

Presentations, emphasizing achievements and opportunities in HPC, are intended for the broad international community, especially students and newcomers to the field. The next webinar in the series, to be held on Wednesday, May 22 at 8 am (Pacific time) is presented by Lori Diachin (Lawrence Livermore National Laboratory) on the topic of the successes of the Exascale Computing Project. Abstract: The duration and scale of the exascale computing project (ECP) provided a unique opportunity to advance computational science in a wide variety of application areas. The project lasted seven years and funded over one thousand researchers to develop 24 applications, over 70 software products, and deploy them on the exascale computers when they were first deployed at the DOE facilities. This results in many notable outcomes including: the first integrated HPC software stack comprising over 100 libraries, performance portable applications refactored for accelerator-based computing architectures, and a new generation of computational scientists exposed to state-of-the-art techniques. In this talk we will give an overview of the exascale computing project and highlight key legacy outcomes that will impact the computational science community for years to come. We will also discuss the major outcomes and lessons learned in creating the exascale ecosystem; particularly in algorithm design and implementation for accelerator-based compute nodes, performance portability across a range of platforms, fostering strong collaborations across multidisciplinary teams, and managing and measuring the success of a computational science project of this scale. ### Join NERSC for May-October OpenMP Training Series <a name="omptraining"/></a> The OpenMP API is the de facto standard for writing parallel applications for shared memory computers supported by multiple scientific compilers on CPU and GPU architectures.
