This year, the hackathon will be virtual and selected code teams will be able to test and develop on [Perlmutter](https://www.nersc.gov/systems/perlmutter/), and there is also the option to use an ARM system. Hackathons combine teams of developers with mentors to either prepare their own application(s) to run on GPUs or optimize their application(s) that currently run on GPUs. This virtual event consists of a kick-off day, where hackers and mentors video-conference to meet and develop their list of hackathon goals, as well as get set up on the relevant systems. This is followed by a one week preparation period before the 3-day intensive primary event. **Please note the deadline to submit a proposal is 11:59 PM Pacific, May 8th 2024.** So [apply](https://www.openhackathons.org/s/siteevent/a0C5e000008dWi2EAE/se000287) now! Teams should consist of at least three developers who are intimately familiar with (some part of) their application, and they will work alongside two mentors with GPU programming expertise. If you want/need to get your code running/optimized on a GPU-accelerated system, these hackathons offer a unique opportunity to set aside 4 days, surround yourself with experts in the field, and push toward your development goals. During the event, teams will have access to compute resources provided by NERSC, and OLCF. For more information, or to submit a short proposal form, please visit the [Open Hackathon’s event page](https://www.openhackathons.org/s/siteevent/a0C5e000008dWi2EAE/se000287) or NERSC's [event page](https://sites.google.com/lbl.gov/august-2024-gpu-hackathon/home). Please contact Hannah Ross (<HRoss@lbl.gov>) with any questions. ### Debugging Challenging Memory and GPU Problems with TotalView, May 13, 2024 <a name="tvtraining"/></a> NERSC is hosting a training event on effectively using TotalView to debug challenging memory and NVIDIA GPU problems. TotalView from Perforce Software is a parallel debugger for complex C, C++, and Fortran applications. Using live demonstrations running on Perlmutter, you'll learn how to leverage TotalView's powerful memory debugging technology to find memory errors in parallel codes, and to debug CUDA, OpenMP, and OpenACC code running on NVIDIA GPUs. For more information and to register, please see the [event page](https://www.nersc.gov/users/training/events/2024/debugging-challenging-memory-and-gpu-problems-with-totalview-may-13-2024/). ([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 most recent addition to the list is an article in the "In Their Own Words" series, on NERSC veteran [Jackie Scoggins](https://www.nersc.gov/news-publications/nersc-news/nersc50/page-9904/). For more on the NERSC 50th anniversary, please see the [NERSC 50th Anniversary](https://www.nersc.gov/news-publications/nersc-news/nersc50/) page. ### Seeking Volunteers for NUG Annual Meeting Planning Committee <a name="nugmtgvol"/></a> Calling all NERSC enthusiasts! We are seeking undergraduate, graduate student, and postdoc volunteers to help us plan the 2024 NUG Annual Meeting celebrating the 50 Years of NERSC! Bring your creativity, enthusiasm, and organizing skills to the monthly one-hour meetings to help create an amazing and memorable meeting.

The series began on Monday, April 15. The first presentation, by Alan Poon (Lawrence Berkeley National Laboratory) was entitled "What We have Learned about the Universe from Low-Energy Neutrino Physics Experiments and NERSC's Role in the Discoveries". A recording of the presentation [is available](https://vimeo.com/939758674) (captioning is still in progress). 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> ## ### Attention Students: NERSC Summer Internships Available! <a name="nerscinterns"/></a> Are you an undergraduate or graduate student who will be enrolled as a student in the fall? Are you interested in working with NERSC staff on interesting technical projects? NERSC is looking for motivated students to join us for the summer in a paid internship role. Qualifications vary depending on the project, and pay is based on years of education completed. We have created a [list of summer internship projects on our website](https://www.nersc.gov/about/work-at-nersc/internships/nersc-summer-internship-projects/). Projects are still being added to the list so please check back for further additions. ### 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.

The theme of the conference is "Yesterday, Today, Tomorrow: A celebration of all that RSEs have done for computing in the past, in the present, and in the future." Topics of interest include but are not limited to: - History of the RSE movement - RSE impact - Efforts to expand the RSE movement - Research data management - Software engineering approaches supporting research - Diversity, Equity, and Inclusion for RSEs and in RSEng - Training and workforce development - Maturing and expanding the RSE profession For more information, including how to submit, please see <https://us-rse.org/usrse24/participate/>. Paper and notebook submissions are due Monday, May 20, and submissions for posters and talks are due Monday, June 3. ### (NEW/UPDATED) Call for Participation – Virtual Workshop: Multiproject CI/CD <a name="cicdworkshop"/></a> Please join 2024 Better Scientific Software Fellow Dr. Ryan Richard (Ames National Laboratory/Iowa State University) for a virtual workshop on multiproject continuous integration/continuous deployment (CI/CD), to be held via Google Meet on June 14, 2024 from 11:00 am-1:00 pm (Pacific 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. For more information please see: <https://multiprojectdevops.github.io/workshop_reports/virtual_workshop1/> ([back to top](#top)) --- ## Upcoming Training Events <a name="section8"/></a> ## ### 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). ### 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. MPI+OpenMP for CPUs and OpenMP device offload for GPUs are recommended portable programming models on Perlmutter. Whether you're new to parallel programming, new to OpenMP or OpenMP device offload, or want a refresher on the basics or explore advanced features, our [OpenMP monthly training series](https://www.nersc.gov/openmp-training-series-may-oct-2024/) is for you.
