", "abstract": "Numerical codes that require arbitrary precision floating point (APFP) numbers for their core computation are dominated by elementary arithmetic operations due to the super-linear complexity of multiplication in the number of mantissa bits. APFP computations on conventional software-based architectures are made exceedingly expensive by the lack of native hardware support, requiring elementary operations to be emulated using instructions operating on machine-word-sized blocks. In this work, we show how APFP multiplication on compile-time fixed-precision operands can be implemented as deep FPGA pipelines with a recursively defined Karatsuba decomposition on top of native DSP multiplication. When comparing our design implemented on an Alveo U250 accelerator to a dual-socket 36-core Xeon node running the GNU Multiple Precision Floating-Point Reliable (MPFR) library, we achieve a 9.8\u00d7 speedup at 4.8 GOp/s for 512-bit multiplication, and a 5.3\u00d7 speedup at 1.2 GOp/s for 1024-bit multiplication, corresponding to the throughput of more than 351\u00d7 and 191\u00d7 CPU cores, respectively. We apply this architecture to general matrix-matrix multiplication, yielding a 10\u00d7 speedup at 2.0 GOp/s over the Xeon node, equivalent to more than 375\u00d7 CPU cores, effectively allowing a single FPGA to replace a small CPU cluster. Due to the significant dependence of some numerical codes on APFP, such as semidefinite program solvers, we expect these gains to translate into real-world speedups.

", "abstract": "To the best of our current understanding, quantum mechanics is part of the most fundamental picture of the universe. It is natural to ask how pure and minimal this fundamental quantum description can be. The simplest quantum ontology is that of the Everett or Many-Worlds interpretation, based on a vector in Hilbert space and a Hamiltonian. Typically one also relies on some classical structure, such as space and local configuration variables within it, which then gets promoted to an algebra of preferred observables. We argue that even such an algebra is unnecessary, and the most basic description of the world is given by the spectrum of the Hamiltonian (a list of energy eigenvalues) and the components of some particular vector in Hilbert space. Everything else\u2014including space and fields propagating on it\u2014is emergent from these minimal elements.", "date": "2019-03-22", "date_type": "published", "publisher": "Springer", "place_of_pub": "Cham", "pagerange": "95-104", "id_number": "CaltechAUTHORS:20180228-094539014", "isbn": "978-3-030-11300-1", "book_title": "What is Fundamental?", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180228-094539014", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Department of Energy (DOE)", "grant_number": "DE-SC0011632" }, { "agency": "Walter Burke Institute for Theoretical Physics, Caltech" } ] }, "other_numbering_system": { "items": [ { "id": "2018-006", "name": "CALT-TH" } ] }, "local_group": { "items": [ { "id": "Walter-Burke-Institute-for-Theoretical-Physics" } ] }, "contributors": { "items": [ { "id": "Aguirre-A", "name": { "family": "Aguirre", "given": "Anthony" } }, { "id": "Foster-B", "name": { "family": "Foster", "given": "Brendan" } }, { "id": "Merali-Z", "name": { "family": "Merali", "given": "Zeeya" } } ] }, "doi": "10.1007/978-3-030-11301-8_10", "primary_object": { "basename": "1801.08132.pdf", "url": "https://authors.library.caltech.edu/records/5f5w2-x7g75/files/1801.08132.pdf" }, "pub_year": "2019", "author_list": "Carroll, Sean M. and Singh, Ashmeet" }, { "id": "https://authors.library.caltech.edu/records/3qmfh-ft455", "eprint_id": 92397, "eprint_status": "archive", "datestamp": "2023-08-19 12:49:17", "lastmod": "2024-01-14 21:28:26", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Preskill-J", "name": { "family": "Preskill", "given": "John" } } ] }, "title": "Simulating quantum field theory with a quantum computer", "ispublished": "unpub", "full_text_status": "public", "note": "\u00a9 owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0). \n\nMy remarks here have been influenced by many colleagues, most of all my collaborators Stephen Jordan, Hari Kvoi, and Keith Lee.

In particular, Euclidean Monte Carlo methods are not well suited for studying real-time evolution in hadronic collisions, or the properties of hadronic matter at nonzero temperature and chemical potential. Digital computers may never be able to achieve accurate simulations of such phenomena in QCD and other strongly-coupled field theories; quantum computers will do so eventually, though I'm not sure when. Progress toward quantum simulation of quantum field theory will require the collaborative efforts of quantumists and field theorists, and though the physics payoff may still be far away, it's worthwhile to get started now.

", "abstract": "There has been a long-standing debate if the chiral phase transition in two-flavor massless QCD is first order or second order. The previous arguments based on epsilon expansions, large N expansions, functional renormalization group, and Monte-Carlo simulations had been all inconclusive with shortcomings. If it were the second order phase transition, there should exist a corresponding three-dimensional conformal field theory which describes the critical phenomenon. The recent development in conformal bootstrap enables us to directly study the (non-)existence of conformal fixed points in a non-perturbative manner. In this proceeding, I review the conformal bootstrap method and its application to this problem. Our conclusion is that the corresponding conformal fixed point should exist and the phase transition will be the second order if the U(1) chiral anomaly is effectively restored. This means that the original 1-loop prediction by Pisarski and Wilczek would be incorrect. We further provide the most precise prediction of the critical exponent there. We believe future numerical simulations will confirm our prediction.", "date": "2015-07", "date_type": "published", "publisher": "SISSA", "id_number": "CaltechAUTHORS:20180828-122924484", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180828-122924484", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "local_group": { "items": [ { "id": "Walter-Burke-Institute-for-Theoretical-Physics" } ] }, "doi": "10.22323/1.251.0002", "primary_object": { "basename": "LATTICE_2015_002.pdf", "url": "https://authors.library.caltech.edu/records/t3e52-6nn38/files/LATTICE_2015_002.pdf" }, "pub_year": "2015", "author_list": "Nakayama, Yu" }, { "id": "https://authors.library.caltech.edu/records/ra4p9-fen57", "eprint_id": 89227, "eprint_status": "archive", "datestamp": "2023-08-20 07:10:16", "lastmod": "2024-01-14 20:42:50", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Nakayama-Yu", "name": { "family": "Nakayama", "given": "Yu" }, "orcid": "0000-0002-1747-5147" } ] }, "title": "IR fixed points and conformal window in SU(3) gauge Theories", "ispublished": "unpub", "full_text_status": "public", "note": "Copyright owned by the author(s) under the term of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License. \n\nThe talk was given on behalf of Prof. Y.

The reduced de-phasing and the faster convergence rate allow us to estimate the phase evolution of the gravitational waves emitted, as well as the magnitude of finite-resolution effects, without the need of phase- or time-alignments or rescalings of the waves, as sometimes done in other works.
