Snowmass Computational Frontier Workshop

US/Central
Benjamin Nachman (LBNL) , Oliver Gutsche (Fermi National Accelerator Laboratory) , Steven Gottlieb (Indiana Univ.)
Description

Every half-decade or so the US high energy physics community engages in a planning process that looks ahead five to ten years to prioritize possible future directions and projects.  There used to be a meeting lasting several weeks in Snowmass, Colorado for this exercise.  Although we no longer have a long meeting there, the name Snowmass has stuck.  The previous plan was called Snowmass 2013, and we are now working on Snowmass 2021, which will culminate with a large meeting July 11-20 in Seattle and a report later that Fall.  Details can be found at the wiki snowmass21.org

The planning is organized by "Frontiers," and we would like to introduce the Computational Frontier.  It is important that experiments and groups doing large scale computations be well represented in the Computational Frontier.  The main page in the wiki for this frontier is here:

 https://snowmass21.org/computational/start

The work within this frontier is organized into seven topical groups:

CompF1: Experimental Algorithm Parallelization

CompF2: Theoretical Calculations and Simulation

CompF3: Machine Learning

CompF4: Storage and processing resource access (Facility and Infrastructure R&D)

CompF5: End user analysis

CompF6: Quantum computing

CompF7: Reinterpretation and long-term preservation of data and code

Each topical group has its own mailing list and slack channel.  Details can be found at the link above for the Computational Frontier, where you will also find links to pages with details about each topical group.

In August 2020, we are pleased to invite the community to our kick-off Computational Frontier meeting. The meeting will take place (virtually) on August 10 and 11.  This site serves as the website for this workshop.  At the meeting, each topical group will present its charge and plans for gathering input from the community. We hope you will attend.

The ZOOM connection details for the plenary sessions and the parallel sessions have been pinned in the #comp_frontier_topics channel on the Snowmass2021 slack (instruction to join at bottom of https://snowmass21.org)

        Network Requirements and Computing Model R&D for the HL-LHC Era 8m

        Summary: Recent estimates of network capacity requirements for the HL-LHC era indicate that these cannot be met through technology evolution and price/performance improvements alone within a constant budget. An in-depth consideration of HL-LHC Computing Model is thus needed, and an R&D program to formulate, design and prototyping of the new Model is recommended. This program could take advantage of current development projects that provide the capability to set up, allocate and end-to-end network paths with bandwidth guarantees, and to coordinate the use of network resources with computing and storage resources.
        2020 Update in the Outlook for Network Requirements:
        In January, at the 43rd LHCOPN/LHCONE meeting at CERN , the LHC experiments expressed the need for Terabit/sec links by the start of HL-LHC operations in 2027-28, preceded by the usual Computing and Storage (and Network) challenges starting during LHC Run3 (2021-4). This was reinforced by the requirements presented by the DOMA project which “foresees requiring 1 Tbps links by HL-LHC (ballpark) to support WLCG needs. This is for the network backbones and larger sites…”
        The quoted network capacity requirements are an order of magnitude greater than what is available now through the present national and transoceanic networks based on 100GE links. As discussed at the LHCONE meeting, in the GNA-G Leadership group meeting that followed, and in the HEPIX Techwatch technology tracking group, these requirements cannot be accommodated solely through the exploitation of technology evolution within a constant budget. As a result, the further development of managed end-to-end services for the LHC and other science programs and the associated plans presented in this note, could be of pivotal importance. Work in this direction should also be guided by DOMA statements that “caching/latency hiding will be important. DOMA is exploring XCache as a mechanism, which provides latency hiding and support for diskless sites (with regional data lakes). Production of AODs (using RAW) will be a network driver, especially regionally. Effectively the ‘site’ is expanded to encompass a ‘region’.”
        • It was agreed in subsequent discussions that the HEPIX Technology Watch WG and/or the Global Network Advancement (GNA-G) leadership group that was formed in the fall of 2019 , can help define how much of it can be satisfied through technology evolution by 2027, and by 2024 in the preparatory phase.
        • The rest will involve a change in paradigm including the end-to-end services involving sites and networks, and orchestration, as is being developed in projects such as SENSE, SANDIE and NOTED (described below). Ongoing discussions should continue to conceptualize and define what the new class(es) of service required entail.
        • An important part of this is the persistent testbed being deployed by SENSE in collaboration with AutoGOLE and other collaborating projects. This is proceeding starting with the current SENSE testbed sites, plus extensions to UCSD, CERN, Starlight in Chicago, and a few other sites in the US and overseas.

        High-performance computing for global fits of parton distributions 8m

        I summarize computational needs for determination of parton distribution functions at (N)NNLO accuracy. Our experience with the latest CT18 global analysis of NNLO PDFs indicates the need for the benchmarked infrastructure for accurate and fast determination of PDFs from QCD data. Reduction of the current PDF uncertainties to meet the targets of the HL-LHC EW precision program and BSM searches will require substantial computing resources and coordination within community. I will discuss some ideas along these lines discussed within the EF06 topical group.

        Measuring Python adoption by CMS physicists using GitHub API 8m

        In the pipeline from detector to published physics results, the last step, "end-user analysis," is the most diverse. It can even be hard to discover what tools are being used, since the work is highly decentralized among students and postdocs, many of whom are working from their home institutes (or their homes).

        However, GitHub offers a window into CMS physicists' analysis tool preferences. For the past 7 years, CMSSW has been hosted on GitHub, and GitHub's API allows us to query the public repositories of users who have forked CMSSW, a sample dominated by CMS physicists and consisting of 19,400 user-created (non-fork) repositories.

        In these 7 years, we see a clear reduction in the use of C++ and increase in the use of Python and Jupyter notebooks. 2019 marks the first year in which CMS physicists have created more Python repositories (excluding Jupyter) than C or C++. Finally, we can also search the code in these repositories for substrings that quantify the adoption of specific physics, plotting, and machine learning packages.

        Understanding how physicists do their work can help us make more informed decisions about software development, maintenance, and training.

        Information Technologies for the HL-LHC in 2030 and Beyond 8m

        The computing, storage and communications challenges of the HL LHC era will extensively use emerging technologies which are currently in various stages of conception and pre-specification, so they are not yet on the computing and more broadly, the experimental roadmap. I will briefly introduce the physics and technology barriers in terms of computational and storage nanoscale feature sizes, the energy required for signaling much beyond 1 Tbps, the application pulls from the Internet of Things to exascale computing to the developing 6G wireless standard expected to emerge circa 2030 with 1 Tbps links. I will point to current authoritative information sources such as the IEEE International Roadmap for Devices and Systems (IRDS) discussing the challenges and visionary approaches being taken to meet the challenges make the transition to the Beyond CMOS era of 2030-2040.

        The Great Beyond at the Exascale: Dynamical Simulations of the Frezzotti-Rossi model 8m

        We give a very short outlook on the computational aspects of dynamical simulations for the study of the Frezzotti-Rossi model of elementary particle mass generation. Having recently demonstrated via lattice simulations that the non-perturbative mechanism exists, we now plan to investigate the compelling theoretical case that within this framework, we will be able to relate all elementary particle masses to a unique energy scale. More concretely, we hope to relate the Higgs mass to the W and/or top quark masses and further, to predict with 20-30% accuracy the scale of new physics to guide future experimental efforts, all without the shortcomings of technicolor and other composite Higgs models.

        We expect that the simulations required to achieve these goals will be about an order of magnitude more complex and expensive than current state of the art lattice QCD simulations, but we have a roadmap involving quenched and partially quenched setups to proceed via several milestones to our final set of dynamical ensembles, which will certainly require Exascale supercomputing resources and a plethora of algorithmic innovations.

        If we succeed, this will be the first time since Wilson that lattice field theory would be a tool driving discovery and not "merely" a computational approach for non-perturbative aspects of the Standard Model.

        BSM Global Fits and GAMBIT 8m

I will also briefly discuss the fits that have been undertaken with the code and computational challenges that we have encountered in those efforts.

        Graph Data Structures and Graph Neural Networks in High Energy Physics with the ExaTrkX Project 8m

        We present a set of techniques studied by the ExaTrkX collaboration for classification and regression of large scale high energy physics data. Using graph structures and geometric machine learning, we observe excellent performance with particle tracking algorithms on silicon trackers and high-granularity calorimeters for HL-LHC, as well as LArTPCs for neutrino experiments. Promising future research directions include jet reconstruction, particle identification, and particle flow algorithms. We argue that these techniques are viable solutions to the scaling problem of traditional track finding algorithms in the era of experiments such as the HL-LHC, and present results of performance scaling against collision event size. We also argue for the use of heterogeneous solutions, such as distributing training and inference across CPUs, GPUs and TPUs.

        Particle Physics and Machine Learning in Education 8m

        The strong and growing role of machine learning (ML) in particle physics is well established and appropriate given the complex detectors and large data sets at the foundational layer of our science. Increasingly, Physics departments are offering curricula to their undergraduate and graduate students that focus on the intersection of data science, machine learning and physics. In this talk, we provide some perspective on the potential role of particle physics in ML education and present some of the opportunities and challenges in the form of open questions for our community to explore.

        we are planning a panel discussion with the topical groups of the Computational Frontier and the audience about the next steps in the Snowmass process for software and computing.

        We want to ask the panelists and the audience questions about what they learned in the sessions so far about topics that span several topical groups or even frontiers. We want to discuss which topics need follow up, for example in the form of smaller workshops or dedicated discussion meetings.

        We hope this helps us to plan the further steps on the way to our Snowmass report.
