With a power of 2.3 petaflops, i.e. 2.3 million billion operations per second, the supercomputer Pangea was the most powerful supercomputer in the world operated by a private company. It is the Total french who offered this exceptional machine for its calculation of Pau. An exceptional machine who, 2 years only after its start-up, will know a serious booster shot. 2.3 petaflops, its power will pass to 6.7 petaflops.
The geophysical simulation, a computing power-hungry activity
Modeling of the basement is a numerical simulation activity that requires a lot of computing power. Lot of power actually. Large tankers are fighting petaflops suddenly because these gigantic machines need analysis data during the campaigns of seismic prospecting led exploration teams, whether at sea or in the most inhospitable regions of the globe. More than the available computing power is high, more analysis can be fine and fast.
In its strategy compute-intensive, Total is a longtime IMS client. For 15 years, the french group bought a supercomputer at the prestigious American constructor. Its latest acquisition, Pangea, a calculator type SGI ICE X consisted of 6912 modules each including 2 Intel Xeon E5-2670 v3, and octo-core microprocessors water-cooled. An extremely powerful machine and which represented total an investment of 60 million euros over four years.
Total remains faithful to SGI and 100% x86
Yet the engineers of Total power requirement was far from be fulfilled. It took several days of calculation this Pangea v1 to analyze seismic data collected during a search on the ground. Pangea, in its current version had slipped from ninth to 20th place in the global ranking of supercomputers. A ranking of course dominated by public research institutes, but in which the Italian oil Eni had ravished total its place as the fastest private machine, with its 4.6 petaflops HPC2. Total remains faithful to SGI and chose to extend Pangea with new ICE X, a 100% solution modules x 86 so that several manufacturers are now moving towards hybrid architectures (x 86 + GPU graphics chips). Total thus privileged software compatibility to the electric power consumption report.
The initial version of Pangea offered 110.592 hearts of calculation, 442 TB of RAM and 18.4 inches of storage. With this update, IMS adds 110.592 hearts worksheet, 589 To of RAM additional. The total power will pass to 6.7 teraflops, power consumption in… 4.5 MW.
