    1. 1. Reservoir engineering in a HPC (zettaflops) world:a ‘disruptive’ presentation(and, how long would it take to run the BOSIM Brent FFM on ‘todays’ HPC) Hans Haringa GameChanger & Reservoir Engineer (‘in rest’) IRD - Emerging Technologies Shell Global Solutions International B.V 1

    4. 4. Supercomputing is the biggest, fastest computing right this minuteLikewise, a supercomputer is one of the biggest, fastest computersright this minute So, the ‘definition’ of supercomputing is constantly changingWhatever happens in supercomputing today will be on your desktopin about 1/3 to 1/2 of a typical length of a ‘regular Shell career’So, if you have experience with supercomputing ‘now’, you’ll beahead of the curve when things get to the desktopJargon: supercomputing is also called High Performance Computing(HPC) 4
    5. 5. Size: many problems that are interesting to scientistsand engineers can’t fit on a PC – usually because theyneed more than a few GB of RAM, or more than a few TBof diskSpeed: many problems that are interesting to scientistsand engineers would take a very very long time to runon a (GID) PC: months or even years.Why bother: HPC gives the ability to do bigger, better,more exciting science. If your code can run faster, thatmeans that you can tackle much bigger problems inthe same amount of time that you used to need forsmaller problems 5

    7. 7. The CDC 7600 breaks the Megaflop/s barrierwith 1.24 Megaflop/s in 1971The Cray 2 (boasting 2 GB) of memoryexceeds the Gigaflop/s barrier in 1986Intel’s ASCI Red broke the Teraflop/s barrierin 1997IBM Roadrunner (3 Megawatt, $133Million) shattered the Petaflop/s barrier in2008flop/s: floating point operations execution rate refers to 64-bit floating-point operations ofeither addition or multiplication (Linpack measure) 7
