Example of recentresults on CURIE Understandingthe evolution of the Universe (1/2) Franco-British Workshop on Big Data in Science • Grand challenge conducted by Observatoire de Paris and the DEUS Consortium (http://www.deus-consortium.org) • Goal : perform 3 FULL Universe simulations, fromBig Bang to nowdaysusing 3 differentdarkenergy distributions • Influence of the darkmatterwrtevolution of the Universe • Direclylinkedwith the 2011 Physics Nobel Prize • Data willbeused to feednext EU EUCLID telescope • Unprecedented HPC requirements • >550 billions particles, 81923mesh in a 21 h-1Gpc box • RAMSES code (CEA) and a dedicatedworkflowtoolchain • 76k cores, >300 TB of main memory • Specificmemory, MPI and parallel I/O optimisations
Example of recentresults on CURIE Understandingthe evolution of the Universe(2/2) Franco-British Workshop on Big Data in Science • WORLWIDE record finished 2 monthsago • First FULL UniverseΛCDM, LCDM and RPCDM simulations performed on Curie thinnodes • 3runs for a total of 92 hourselapsedon 76 032 cores, last runlasted 29 hourswithoutanyfailure WWOOUUAAHHH CURIE isvery stable ! • A strongneed of substained I/O rate on the Lustre scratch fs • We have herea BigDataproblem • A total of 10 PB of full data (scratch and rough data) generated • 4 PB of rough resultsafter simulation • 1.2 PB of refined data after post processing for the 3 darkenergy simulations need to be made available to worldwidescientists !
Explosion of computational dataAn anotherexamplefromclimatology Franco-British Workshop on Big Data in Science • Evolution of the global climate • 5th IPCC campaign , French production on a dedicated NEC SX9 : > 1TB/day • Strong issues with storage, post processing and archive of data • And the future is :
One conclusion Data isexploding Franco-British Workshop on Big Data in Science • Observational/experimental data • Particle accelerators and detectors (LHC@CERN) • Genome sequencer and personalized medecine • Next gen satellites and (radio)telescopes • Captors/sensors in weather forecast/climatology or oil & gas • Finance, insurance, … • Computational data • Increase on HPC resources (PRACE = 15 PF in 2012) • Increase of space and time resolution of models • Multi-physics and multi scale simulations • Rise of uncertainties quantification, ensemble simulations, … • With problems relative to • Size of data (number and size of files), (un)structured data, format, ..) • Uncertainties of data and fault tolerance • Metadata issue • Post processing (20% of time) • Dissemination of refined data to worldwide communities during decades That means : To deploy PERENE and SUBSTAINABLE Research Infrastructures
Another conclusion People isaware about that ! Franco-British Workshop on Big Data in Science • On the hardware and system software side • Multi level storage with new I/O devices : mix of flash based memory (SSD, PCM, …) with hard drives • Asynchronous I/O and Active I/O (servers embedded into I/O controllers) • Next generation of parallel file system (Lustre, GPFS, Xyratec, …) • Flops will be “almost free” -> post processing at the same time as computation • A lot of European projects and R&D initiative • PRACE implementation projects : data management, remote viz, portals, … • EUDAT : data services between computing/data centers and end users communities • EESI2 : cartography about Exascale R&D efforts • French INRIA Blobseer R&D project, … • But a lot of applications will need to be rewritten/adapted • The complete I/O strategy need to be re thinked • New methods for data analysis/exploration are needed (MapReduce, Hadoop, NOSQL, …?) • Rough data will stay in computing/data center and ONLY refined data will go out • Networks bandwidth will need to increase • Use of remote visualisation
HPC : en route to international synergies • Global European HPC ecosystem integration Franco-British Workshop on Big Data in Science HPC enables scientific discoveries and innovation for both research and industry Wemustn’tfollow the trends. We must anticipate them ! • To face future societal or industrial challenges • To prepare users for future parallel architectures and applications • To increase involvement of scientists or engineers in these techniques
