This technique is called ‘swapping’ and is a method also employed by regular PCs, for example with Windows or Mac.The value of Pi is usually figured out to four or five digits. To work around this limitation, the Pi calculation program stores a large portion of its memory on hard disk drives. 34 of these disks are used for swap space and 4 disks will hold the final Pi digitsĢ SSDs in a RAID configuration for storing the operating systemĪlthough our installed RAM is very large compared to a regular desktop PC, it would only be enough to calculate Pi to a few 100 billion decimal places. For this type of computation processor performance is of secondary importance.ģ8 hard disk drives running at 7,200 rpm and with 16 TB each. Prospective students will benefit from access to powerful hardware and will be able to practice newly acquired theoretical knowledge using state-of-the-art hardware and software.Ĭalculating Pi to the trillion digit range demands extreme amounts of RAM and swap space as well as high memory bandwidth. This also includes implementing a new degree programme in the field of 'Computational and Data Science'. Dr Heiko Rölke.ĭAViS as part of the University of Applied Sciences of the Grisons is consolidating expertise in the area of high-performance computing (HPC) and HPC infrastructure for a mandate of the canton of Grisons. The challenge for this record attempt is taken up by project leader Thomas Keller and by the head of DAViS, Prof. Furthermore, we would like to test our ability to reliably manage a several-months-long running computation.

Such an endeavour not only requires the selection of the appropriate hardware but also needs expertise in assembling, configuring and tuning hardware and software for maximum performance. Although there is no practical application in knowing trillions of decimal places of a transcendental number, this is however, a useful test of our abilities to run extremely resource-demanding computations.
