Synopsis
The International Symposium on Supercomputing - New Horizon of Computational Science was held on September 1-3, 1997 at the Science MuseuminTokyo,tocelebrate60-yearbirthdayofProfessorDaiichiroSug imoto,who hasbeenleadingtheoreticalandnumericalastrophysicsfor 30 years. The conference coveredexceptionally wide range ofsubjects, to follow Sugimoto'saccomplishmentsinmanyfields.Onthefirstdaywehadthree talksonstellarevolutionandsixtalksonstellardynamics. Onthesecond day, six talks on special-purpose computingand four talks on large-scale computing in MolecularDynamicswere given. Onthethirdandthelast day,threetalks on dedicatedcomputerson LatticeQCDcalculationsand sixtalksonpresentandfutureofgeneral-purposeHPCsystemsweregiven. Inaddition,some30posterswerepresentedonvarioussubjectsincompu tationalscience. Instellarevolution, D.Arnett (Univ. ofArizona) gaveanexcellenttalk on the recent development in three-dimensionalsimulation ofSupernova, inparticularonquantitativecomparisonbetweendifferenttechniquessuch asgrid-basedmethodsandSPH (SmoothedParticleHydrodynamics). Y. Kondo (NASA) discussedresentadvanceinthemodelingoftheevolution ofbinarystars,and1.Hachisu(Univ. ofTokyo)discussedRayleigh-Taylor instabilitiesinsupernovae(contributionnotincluded). Instellardynamics, P.Hut(lAS)gaveasuperbreviewonthelong-term evolution ofstellarsystem, J. Makino (Univ. ofTokyo) described briefly theresultsobtainedonGRAPE-4special-purposecomputerandthefollow up project,GRAPE-6,whichisapprovedas ofJune 1997. GRAPE-6will be completed by year 2001 with the peak speed around 200 Tflops. R. Spurzem (Rechen-Inst.) and D. Heggie (Univ. of Edinburgh) talked on recentadvanceinthestudyofstarclusters,andE.Athanassoula(Marseille Observatory) describedthe work doneusingtheirGRAPE-3 systems. S. Ida (TokyoInst. ofTechnology) describedthe result ofthe simulationof theformationofMoon. Thefirst talkoftheseconddaywas given by F-H. Hsu oftheIBMT.J. Watson Research center, on "Deep Blue", the special-purpose computer for Chess,which, forthefirst timeinthehistory, wonthematchwiththe besthumanplayer,Mr. GaryKasparov(unfortunately,Hsu'scontribution isnot included in this volume). Then A. Bakker of Delft Inst. of Tech nology looked back his 20 years ofdevelopingspecial-purpose computers formoleculardynamicsandsimulationofspinsystems. J.Arnoldgavean overviewoftheemergingnewfieldofreconfigurablecomputing,whichfalls inbetweentraditionalgeneral-purposecomputersandspecial-purposecom puters. S.Okumura(NAO)describedthehistoryofultra-high-performance digital signalprocessors for radio astronomy. They havebuilt a machine with 20GaPS performance in early 80s, and keep improvingthe speed. M. Taiji (ISM) told on general aspects of GRAPE-type systems, and T. Narumi (Univ. of Tokyo) the 100-Tflops GRAPE-type machine for MD calculations,whichwillbefinished by 1999.
Synopsis
This conference proceedings covers an exceptionally wide range of subjects in computational science, from astrophysics to molecular science and from general-purpose high-performance computers to special-purpose computing devices. The unique nature of this book is that the main topic is the interaction between the requirement from application and the design of high-performance computers. In particular, special-purpose computers for molecular dynamics, Lattice QCD, and astrophysics are discussed. This book will be of interest to astrophysicists, physicists and chemists who are involved in computer simulation. It will also be of interest to computer scientists with interest in hardware architecture of high-performance computers.
