Scalable IO Workshop at Argonne National Laboratory

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.

Knights Landing Hackathon at Brookhaven

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.

HEP-CCE Announces 2018 GRADUATE STUDENT SUMMER INTERNSHIP PROGRAM

The HEP-CCE is happy to announce a call for applications to its 2018 GRADUATE STUDENT SUMMER INTERNSHIP PROGRAM. This program gives graduate students in HEP with a strong interest in computing a chance to work with teams at DOE laboratories on challenging problems currently facing HEP.

Applications to the program should include a CV, a statement of current research, and a short statement on how participation in the program will benefit the student’s current work and future career. A letter of recommendation from the student’s research adviser is also required.

Deadline: March 2, 2018
