But at this point in time that is a ridiculously high number of cores. It is hard to give a suggestion for real-world limits as indexes vary a lot and the rules of thumb tend to be quite poor when scaling up. http://lucidworks.com/blog/2012/07/23/sizing-hardware-in-the-abstract-why-we-dont-have-a-definitive-answer/ People generally seems to run into problems with more than 1000 not-too-large cores. If the cores are large, there will probably be performance problems long before that. You will have to build a prototype and test. - Toke Eskildsen, State and University Library, Denmark
