9th WACCPD Workshop @ SC22 Call For PapersThe Call for Papers for the 9th Workshop on Accelerator Programming Using Directives is now open! The workshop aims to showcase all aspects of accelerator programming for heterogeneous systems such as innovative high-level language or library approaches, lessons learned while using directives or other portable approaches to migrate scientific legacy code to modern systems, and compilation and runtime scheduling techniques. The paper submission deadline is August 5, 2022 AOE. For more information, see https://www.waccpd.org/.

2022 P3HPC Workshop @ SC22 Call for Papers

The 2022 International Workshop on Performance, Portability & Productivity in HPC (P3HPC) call for papers is now open! P3HPC provides a forum for researchers and developers to discuss their successes and failures in tackling the compelling problems that lie at the intersection of performance, portability and productivity (P3) and High-Performance Computing (HPC). The topic of P3 touches on many aspects of HPC software development and the workshop program is expected to reflect a wide range of experiences and perspectives, including those of compiler, language and runtime experts; applications developers, performance engineers; and domain scientists. The abstract submissions deadline is August 8, 2022 AOE and the full paper submission deadline is August 12, 2022 AOE. For more information, please see: https://p3hpc.org/workshop/2022/

17th Workshop on Workflows in Support of Large-Scale Science @ SC22 Call for PapersThe Call for Papers for the 17th Workshop on Workflows in Support of Large-Scale Science is now open! The workshop focuses on the many facets of scientific workflow management systems, ranging from actual execution to service management and the coordination and optimization of data, service, and job dependencies. The workshop covers a broad range of issues in the scientific workflow lifecycle that include: scientific workflows representation and enactment; workflow scheduling techniques to optimize the execution on heterogeneous infrastructures; workflow enactment engines that deal with failures in the application and infrastructure; and a number of computer science problems related to scientific workflows such as semantic technologies, compiler methods, fault tolerance, etc. The paper submission deadline is August 15, 2022 AOE.

Meetings & Workshops

Training on HDF5 for HPC Data Models, Analysis, & Performance

On July 27, ALCF will host a one-hour webinar entitled “Introduction to HDF5 for HPC Data Models, Analysis, and Performance.” This webinar is open to NERSC and OLCF users.

The webinar is a comprehensive overview of HDF5 for anyone who works with big data in an HPC environment. The talk consists of two parts. Part I introduces the HDF5 data model and APIs for organizing data and performing I/O. Part II focuses on HDF5 advanced features such as parallel I/O and will give an overview of various parallel HDF5 tuning techniques such as collective metadata I/O, data aggregation, async, parallel compression, and other new HDF5 features that help to utilize HPC storage to its fullest potential.

Please find more information on the ALCF event page at https://www.alcf.anl.gov/events/introduction-hdf5-hpc-data-models-analysis-and-performance

AI for Science Bootcamp
August 25-26
NERSC, in collaboration with NVIDIA, will present a 2-day bootcamp designed to teach users fundamental concepts and practices in deep learning, and how to effectively apply them to scientific problems. Participants will learn how to implement the primary components of deep learning workflows, including hands-on exercises training and evaluating custom deep-learning models on scientific datasets.

For more information and to register, please see https://www.nersc.gov/users/training/events/nersc-ai-for-science-bootcamp-august-25-26-2022/. Space is limited, and active NERSC/ALCF/OLCF users will be prioritized during the registration process.

July 2022 OLCF User Conference call 
July 27, 2022

The July OLCF User Conference Call will be held from noon until 1:00 PM Eastern Time on Wednesday, July 27. During this call, OLCF’s Benjamín Hernández will present “Remote Visualization with VNC”, which will cover how to remotely connect to Andes using VNC and how to interact with graphical applications. For more information, see the event page at https://www.olcf.ornl.gov/calendar/userconcall-jul2022/

Introduction to OpenMP Offload
August 11, 1:00-3:30 pm EDT,Part 1: OpenMP Basics of Offload
September 1, 1:00-3:30 pm EDT,Part 2: OpenMP Optimization and Data Movement
Virtual via Zoom
These sessions, offered by OLCF and NERSC, are part of the OLCF’s Preparing for Frontier training series. Please click this link to visit the main page to see other sessions in the series. These OpenMP Offload trainings twill enable application teams and developers to accelerate their code with the use of GPUs, as well as exploiting the latest OpenMP functionality to program multi-core platforms like Summit, and Perlmutter. Both Part 1 and Part 2 of this training will have focused discussion about what you need to prepare for using OpenMP on Frontier.

Register for Part2, OpenMP Optimization and Data Movement at: hxxps://www.olcf.ornl.gov/calendar/introduction-to-openmp-offload-part-2/

Using R on HPC Clusters Webinar
August 17,19 1:00- 4:00 pm EDT
Virtual via Zoom
This OLCF hosted tutorial Webinar helps users learn a basic workflow for how to use R on an HPC cluster. The tutorial will focus on parallel computing as a means to speed up R scripts on a cluster computer. Many packages in R offer some form of parallel computing yet they rely on a much smaller set of underlying approaches: multithreading in compiled code, the unix fork, and MPI. The tutorial will take a narrow path to focus on packages that directly engage the underlying approaches, yet are easy to use at a high-level. This workshop is targeted for users of OLCF, CADES, ALCF and NERSC. Users who do not already have accounts on those system are welcome to attend the lectures but will not be able to participate in all of the hands-on activities.

Data Visualization & Analytics Series: ParaView at OLCF
September 15, 2022 1:00pm – 3:00pm EDT

ParaView is an open-source data analysis and visualization application that allows users to quickly build visualizations to analyze their data. Available in both a GUI mode and a batch mode, ParaView is able to analyze extremely large datasets using distributed memory computing resources. This beginner friendly event will provide an overview of how to access ParaView at OLCF and a tutorial of how to use ParaView to visualize different datasets.

The hands-on component of this training is limited to users with moderate security enclave projects (i.e. able to access Summit/Andes), although others are welcome to sign up and attend the presentations. Additionally, hands-on examples will be available after the event for Moderate users to access and work with on their own. For more information or to register, see https://www.olcf.ornl.gov/calendar/paraview-at-olcf/

File System Purge Policy

In order to ensure available space for all active workloads, the temporary scratch filesystems are purged daily removing files that have not been accessed or modified in the last 90 days (specifically, the file’s atime and mtime attributes). Operations such as reading or writing to a file update these timestamps, other operations such as “ls” do not. You can check a file’s atime and mtime with the “stat” command. Since the temporary scratch filesystems are not automatically backed up, it is good practice to back up needed files to the center’s HPSS and/or to off-site archives.
