Evolution of successful Forum for Computational Excellence (FCE) Pilot project – raising awareness for HEP response to rapid evolution of the computational landscape Transitioning from FCE to CCE: Center for Computational Excellence –More interactive and task-oriented with “laser focus” on emerging architectures in exascale and “Post Moore” computing environments. Focus area’s include Exascale systems – optimal configuration issues for HEP apps Intelligent networking Exascale infrastructure fabric (cyber, caching, data movement) Machine learning and other data-intensive analysis tools –Center would be co-located at ANL, LBNL, and FNAL Over the next year –Establish technical leads and initial projects, provide collaboration infrastructure and initiate summer programs –Incubate new technical projects Center for Computational Excellence (CCE) 1

FCE Highlights Over Last Year FCE Kickoff meeting at ANL last September to get organized Led an ASCR/HEP exascale computing review Published our 3 working group reports arXiv: Led the HEP portion of an ASCR workshop entitled Data Management, Visualization, and Analysis of Experimental and Observational Data (EOD) Workshop Established a web presence – Coordinated submission of 5 white papers for ASCR Exascale application call. Submitted a co-design center white paper Executed on 3 target areas –Mini-apps –Data Transfer Project –Software containers (and related work)

Mini Apps Mini-apps (Heroux/Barrett): Compact, self-contained proxies that adequately portray the computational loads and dataflow, but are not meant to be scientifically realistic HEP mini-app collection (thousands of lines of code each) will be a good way to develop a design suite for next-generation architectures and insure that the exascale landscape can handle our workflows Mini Apps developed for –Computational Cosmology (ANL Lead) –Lattice QCD (FNAL Lead) –CMS Workflow (FNAL Lead) –Geant4 (FNAL Lead) –Neutrinos (LArSoft) (FNAL Lead)

Software Containers Data Intensive Computing often require complex software stacks. Efficiently supporting “big Software” in an HPC environment offers many challenges Shifter – developed using Docker Technology” to support user-defined and user-provided application images for todays HPC machines Recently featured in HPC Wire and other media outlets Microboone now successfully piloting “shifter” technology to utilize HPC for part of its computing repertoire ESNET in conjunction with the big computing facilities have been working to improve data movement between facilities. Factor of 2 improvement already from what had existed Establishing protocols and tools to make petabyte/day transfers straight forward Networks

For HEP to execute its ambitious science program of the next decade, we needs exascale computing We are motivated to partner with ASCR to ensure success of our exascale program We need guidance on how to build the proper partnerships Final Thoughts 10/5/155
