More Digits friendly Competition


A friendly competition of exact real arithmetic software will be held in Nancy during the RNC7 conference. The goal is to measure the performance of various numerical computing packages on a set of challenging problems, with a strong emphasis on accuracy.

All packages with arbitrary precision capabilities are welcome to compete, with no restriction on the programming language of implementation, as long as you can run it on our competition machine (a 32-bit Pentium-4 3GHz processor running GNU/Linux). If you develop, maintain, or just use such a software, don't hesitate to take part in the friendly competition, telling us which software you intend to use.

The competition will consist of 16 problems. The main emphasis will be on the correctness of the results, not the timings. Nevertheless, during the competition there will be just one hour of time for each participant to solve all the problems together.

The 16 problems are grouped as follows:

As organizers, the MPFR and iRRAM teams did not compete.


You can download the current version of the set of problems as a PDF file. The parameters file used for the competition is now available.
