([back to top](#top)) --- ## NERSC Updates <a name="section5"/></a> ## ### (NEW/UPDATED) NERSC Documentation (docs.nersc.gov) Navigation Bar Improvements to Usability <a name="docsreorg"/></a> Based on user testing and feedback, we will be introducing changes to the navigation bar at [docs.nersc.gov](https://docs.nersc.gov) for improved usability. These changes will go live later this week, so please be on the lookout for updates to the navigation sidebar. As always, please submit any questions or feedback to us at the [NERSC helpdesk](https://help.nersc.gov). ### 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. ### HPSS Archive Unavailable July 14-19 for Major Upgrade <a name="hpssoutage"/></a> NERSC’s HPSS Archive system will undergo a major upgrade from version 7.4.3 to version 9.3, improving its performance, capabilities, and ease of use, and simplifying the process of performing further upgrades in the future. The upgrade process requires that we take the **HPSS Archive system down beginning at 7 pm (Pacific Time) on July 14 and ending at 5 pm on July 19, 2024**, while we update the software and hardware of the system. User data will remain safely stored on the archive, but it will be inaccessible during the downtime period, so please plan accordingly.

With supercomputers such as Aurora, Polaris, Perlmutter, and Frontier deployed across DOE national laboratories, there is now a range of GPU-based architectures for researchers to use from different vendors. The good news is that it is possible to write code using a single programming model and language deployable across all these supercomputers and other systems. Register now for a webinar that will show you how to achieve portable code using the oneMKL library. oneMKL is based on the oneAPI specification and can be used to target multi-vendor and multi-architecture accelerators from a single code base. It is also now governed by the Unified Acceleration Foundation (UXL), an open governance body that is part of the Linux Foundation. We will also talk about the GROMACS and NWChem projects that are benefitting from using the oneMKL library to target Intel, Nvidia, and AMD GPUs, with discrete Fourier transforms as an example. The oneMKL interface library makes this possible with minimal overhead using SYCL backend interoperability.

This training is geared towards novice parallel programmers with prior programming experience in a compiled programming language. In this course, students will learn to write parallel programs that can be run on a supercomputer. We begin by discussing the concepts of parallelization before introducing MPI and OpenMP, the two leading parallel programming libraries. Finally, the students will put together all the concepts from the class by programming, compiling, and running a parallel code on one of the NERSC supercomputers. Training accounts will be provided for students who have not yet set up a NERSC account.
