YouвЂ™d want that much RAM times 4 for the computation (so 16 TB RAM) and 8 times as much disk for the DTZ (distance to conversions) values, so 32 TB disk, but 100 TB disk is a bit easier). For one such pawnless endgame, an uncompressed bit image is 2 45 bits or 2 42 bytes or 4 TB, figuring about a factor of 8 for symmetry. Ten thousand times a second.Дepends entirely on the hardware of course since itвЂ™s highly parallelizable. This gives us about 10 95 operations per second, enough to solve chess. The top supercomputers do about 10 15 operations per second and we estimate there to be about 10 80 electrons in the universe (with these numbers it doesn't matter at all if we consider the protons or not). Let's also look at the estimate by /u/SpaceRook into account (We couldn't do it even if every electron, proton and neutron was a supercomputer): Some mathematicians argue that this number is too high, but don't give a better estimate.ДЄccording to two researchers at Ars Technica the total computational power of mankind is close to 10 19 operations per second, that is equivalent to 10 13 1-MHz processors, bringing down the estimated upper limit to 10 77 years.ДЇor comparison, the estimated time for all nucleons in the observable universe to decay is 10 38 years, so we need to improve our current processing power by a factor of about 10 30. Information theorist Claude Shannon estimates that creating a 32 man table base would take 10 90 years on a 1 MHz processor. Practically speaking, it's probably significantly less actual calculation time, but also unlikely to run on that machine. If we assume the time spent would increase linearly with the size of the database, and decrease by computing power, we could estimate the time to calculate an 8-man tablebase on the current fastest super computer ( 125Pflops) as:Д¦ months * 100 * (1.7 / 125) = 8.16 months on the world's fastest super computer.

What is unclear is whether the lomonosov computer worked on this problem exclusively for 6 months, or if the above article just meant the team SPENT 6 months and the super computer actually only worked on it for some fraction of that time (which is almost certainly the case - but I couldn't find any information about how long the actual calculation took). This article from the Lomonosov tablebase page estimates that the size of an 8-man tablebase will be ~100x larger than a 7-man table base and will take a minimum of 10,000 TB of disk space and 50 TB of RAM, limiting its completion to a top-10 super computer (though I do wonder about the options available in the form of AWS compute cloud lol). This computer was equipped with 52,168 x86-64 cores, 954,840 GPU cores, and 92 TiB of RAM for a peak performance of 1.7PFlops, which is the approximate equivalent of ~150 1080 ti GTX cards in parallel (at 11.3 tflops each). Please continue to give us your feedback and suggestions on how we can help make /r/chess better for everyone.ДЄccording to this page, the 7-man tablebase was calculated in 6 months by the Lomonosov super computer in 2012.
