NERSC is hosting a Kokkos training event organized by the Exascale Computing Project (ECP) on March 26-29, 2019 in Oakland. The training will cover the minimum required topics to get your application started on using Kokkos. Kokkos experts will be on hand to help beginning and more advanced users.
Kokkos is a programming model and library for writing peformance-portable code in C++. The abstractions for on-node parallel execution and data layout in Kokkos are mapped at compile time to fit a device architecture for best performance. Kokkos could be a valuable tool for creating codes that will run efficiently on Perlmutter and other architectures.

The call for applications for the Argonne Training Program on Extreme-Scale Computing (ATPESC) is now open. The deadline to apply is March 4, 2019. This year’s program will be held July 28-August 9, 2019. Doctoral students, postdocs, and scientists interested in conducting computational science and engineering research on large-scale computers are encouraged to apply. Application instructions can be found at: http://extremecomputingtraining.anl.gov/application
Registration for the NERSC New User Training that will be held on January 25, 2019 is now open.
The purpose of the training is to provide users new to NERSC with the basics on our computational systems; accounts and allocations; programming environment, tools, and best practices; and data ecosystem.
The training will be presented online using Zoom technology and in person at LBL’s Shyh Wang Hall (Building 59, CRT) in Room 4102.

On February 11-13, 2019, the Oak Ridge Leadership Computing Facility (OLCF) will host a Summit Training Workshop on-site at ORNL. This event is meant to help new Summit users (or those intending to use Summit) get up and running on the system. Each day will consist of presentations in the morning followed by hands-on sessions in the afternoons. The presentations are meant to deliver relevant information about the system, while the hands-on sessions are intended to help participants get their own codes running on Summit.
OLCF staff and our vendor partners will be available to help during the hands-on sessions. If you would like more information, or to register, please visit the event page at
The 2018 Smoky Mountains Computational Sciences and Engineering Conference (SMC18) is currently accepting teams to participate in its 2nd Annual Data Challenge. This contest is open to
students, faculty, and industry professionals who are interested in performing novel analysis on real scientific data sets. Teams of one to four people may participate.
ORNL data sponsors will provide teams with actual scientific data sets to explore 3 to 5 related challenge questions. The challenge questions for each data set will cover multiple difficulty levels, with the first question in each challenge being suitable for a novice, and each question thereafter increasing in difficultly,
with the series of questions ending with an advanced/expert level challenge question. The top teams will be invited to attend SMC18 in Gatlinburg, TN, where they will present their work and the winner will be crowned. Registration is open until June 22 and the competition ends July 31 (submissions are due by 5:00 PM Eastern on July 31).
The Data Challenge is intended to draw scientists and researchers who may be at the beginning stages of incorporating data analytics into their workflow, to data analytics experts who are interested in applying novel techniques to data sets of national importance.

Applications Open for GPU Hackathon at Brookhaven National Laboratory, September 17-21, 2018
Brookhaven National Laboratory will host its 2nd GPU Hackathon on September 17-21, 2018. The Hackathon will bring together domain scientists, computational scientists, tools developers and hardware vendors to accelerate scientific codes on GPUs through the 5-day intense hands-on training. Team applications are being accepted until June 30, 2018. For more details, go tohttps://www.bnl.gov/gpuhackathon2018
INTRO TO HPC TRAINING (JUN 26-28)
The OLCF will host an Introduction to High Performance Computing (HPC) workshop on June 26-28, 2018. This training will start by covering basic skills, such as UNIX, vim text editor, and c/Fortran programming, which will be necessary for the topics to follow. We will then move on to cover basic parallel programming (using MPI and OpenMP) and GPU computing (CUDA and OpenACC). Hands-on sessions will be included with many of the topics to give participants the opportunity to practice new skills. For more information about this event or to register,
The OLCF will present an Introduction to Summit webinar from
1:00 PM until 4:30 PM (Eastern Time) on Friday, June 1. In this
webinar, we will cover the basic topics new users will need to
get up and running on Summit. We will give a broad overview of
available features and the details necessary to submit and run
jobs. For more information, please see the event page at
The HEP-CCE announces the Scalable IO Workshop at Argonne National Laboratory
23-24 August 2018
High Energy Physics experiments continue to become more data and simulation intensive. There is an expected factor of ten (or more) gap between projected computing needs for HL-LHC experiments and projected growth of current HEP resources. In the US, High Performance Computing resources are going to be growing by more than an order of magnitude by 2021/2022 with the deployment of the US DOE’s first exascale supercomputers. These resources are already becoming an important piece of the HEP computing landscape and will continue to become more important.
One challenge of using leadership computing resources is reading and writing data in scalable ways that does not lead to bottlenecks or performance penalties on the shared filesystems. This Workshop aims to bring together leading IO experts in the HEP field with experts from DOE ASCR Facilities to discuss how to move forward in the next years to make HEP software more friendly to millions of parallel threads accessing files on shared disks.
On February 26-March 2, 2018, Brookhaven National Laboratory (BNL) hosted a hackathon targeting the Intel Xeon Phi (formerly code-named Knights Landing, or KNL) processors for scientists to come together to optimize their application code performance on the KNL-based supercomputers. Out of the five teams who participated, two teams came from the high energy physics community:
- APES (Accelerator Particle Energy Simulator): A code for tracking particle-device and particle-particle interactions that has the potential to be used as the design platform for future particle accelerators. Team members all came from BNL.
- ART: a code for simulating the formation of structures in the universe, particularly galaxy clusters. Team members came from Yale University and University of Miami.
Each team was paired with a mentor with similar scientific background. They also had access to four floating mentors from Intel who brought expertise in OpenMP, Intel hardware architectures, compilers and performance profiling tools. The teams worked with their mentors for five days in a hands-on setting. By the end of the week, all teams achieved significant performance improvements for their codes, with ART and APES achieving >2X and >5X speedup, respectively.
