This looks cute. --Rich ----- Subject: [CCA] "Many Digits" Friendly Competition 2005 : Call for Participation From: Milad Niqui <milad@cs.ru.nl> Reply-To: manydigits@cs.ru.nl Date: Fri, 15 Jul 2005 20:57:26 +0200 Sender: owner-cca-list@fernuni-hagen.de [Apologies for multiple copies] THE "MANY DIGITS" FRIENDLY COMPETITION 2005 4 October 2005 Radboud University, Nijmegen, The Netherlands Call For Participation <http://www.cs.ru.nl/~milad/manydigits> In the Institute for Computing and Information Sciences at Radboud University Nijmegen we will organise a friendly competition/benchmark session for investigating the state of the art in the various implementations of exact real arithmetic. The event will be held on October 4th 2005, in conjunction with the Small TYPES workshop on Constructive analysis, types and exact real numbers <http://www.cs.ru.nl/fnds/typesreal/>. The event will be akin to those held in CCA00 <http://www.cs.swan.ac.uk/~csjens/pdf/resart.pdf> and CCA2002 <http://www.informatik.uni-trier.de/~mueller/cca2002/>. All the interactive software packages capable of handling arbitrary precision arithmetic on elementary functions are invited to participate. Moreover all libraries for handling arbitrary precision arithmetic in any programming language are welcome to participate provided that the participant writes a suitable interface/program. The participants can choose to attend the event at Nijmegen, or they can choose to participate remotely via Internet. Friendly Competition The friendly competition consists of giving a solution to a set of problems that are posed by the organisers shortly (few hours) before the event. The problems cover the minimum abilities of a system capable of handling the elementary real functions and are expected to ask for a large (>=10,000) number of digits. An example of a problem that might be in this set is to calculate the first 10,000 digits of sin(sin(1)). A set of `practice problems' can be found on the website of the competition <http://www.cs.ru.nl/~milad/manydigits/sample_questions.php>. The solutions consist of the input needed to generate the answers to the problems plus the answers themselves. The competition criteria will be the accuracy (correctness) of the solution and the time needed for producing the solution. Apart from this, we will also compare the other aspects of the solutions (such as memory usage and readability and length of the input code) to give a better comparison. On the day of the competition the solutions will be executed by participants on one specific machine at the event site, under either Debian/GNU Linux or Windows XP. A more detailed description of the setup and format of the competition can be found on the website of the competition <http://www.cs.ru.nl/~milad/manydigits/rules.php>. The outcome of this friendly competition is expected to give a comparison in performance of the systems that chose to participate for the selected problems. Remote Participation In case of remote participation, the participants will receive the set of problems by email. Then they will be given the opportunity to log into our local machine and perform their solution. Systems, Packages and Libraries Those who wish to participate in the Friendly Competition are expected to provide the software necessary for their solutions, so it can be run on the machine used for the competition. Schedule * August 26th deadline for registering for the competition * August 29th final list of registered participants on the web * September 23rd timings of the practice problems for the registered participants posted on the web * October 4th competition Registration If you are interested in participating in the event we will be happy to hear from you: 1.Team name, name and email of contact person(s) and the platform your system needs to run (GNU Linux or Windows XP). 2.Whether you plan to come to the meeting or whether you would like to participate remotely. We would prefer that participants (especially those whose system requires Windows) to send their intention to participate before August 26th, 2005. Please register by sending mail to <manydigits@cs.ru.nl>. Best Regards, Local Organisers: Milad Niqui and Freek Wiedijk
