What is RakeSearch?

The enormous size of the diagonal Latin squares space makes it unfeasible to enumerate all its objects straightforwardly in reasonable time. So, in order to discover the structure of this space, sophisticated search methods are needed. In RakeSearch project, we implement an application that picks up separate pairs of mutually orthogonal DLSs, which allows to reconstruct full graphs of their orthogonality. You can contribute to our research by running a free program on your computer.

Peacock butterfly and first half of August 2018
Dear folks!

The August Sun falls faster and faster over the horizon and like a butterfly, summer prepares to fly up and hide into Karelian lakes, forests and rivers. Peacock butterfly will be a symbol of this month! Since the beginning of the months 1434 results with "permutational" ODLS pairs were found by 156 participants and we congratulate:

Happy birthday to RakeSearch project!
Dear crunchers!

Today, on August 11, we proudly celebrate the first birthday of RakeSearch project.

It is a joy for us to have managed such project for already a year. This is 1316 years of CPU time - which means that on average, 1316 cores perform computations.

By now, we have processed 27.5% of all possible workunits. This resulted in 90 found graphs of ODLSs.

On the peak load the project reached 60.6 Teraflops.

Many thanks for the participation and good wishes to all of you!

With best wishes, RakeSearch team:
hoarfrost and Natalia.

July 2018 totals
Dear participants!

A fascinating July is over! We watched a World Cup Final, Red Bull victory on home Spielberg track and "guest victories" of Vettel on Silverstone and Hamilton on Hockenheimring with the subsequent in Hungary. Many people could see a large-scale celestial mechanics show, when one night of 27th July Moon walks through Earth shadow near bright Mars, which approach at this night on minimal distance to our home world.

With your help RakeSearch project is also sufficiently speed-up during Formula BOINC race and received a many results with ODLS pairs! In second half of July 3384 results (in first - 1286, total by month - 4670) have been found by 200 participants and we congratulate:

Formula BOINC RakeSearch GP race report and medal ceremony
The weekend from 27th to 29th of July was hot and fruitful! The most active teams, at these days, were racing on RakeSearch track for taking a leadership in leagues, points, and science, of course.

But the noise of engines was firstly heard before - when on Wednesday and Thursday teams began to open pit-late and deploy big harvesters on the project track and bunkering tasks harversted by them, into huge crunch tanks. The battle for the pole-position bettween XtremeSystems, [H]ard|OCP, SETI.USA and Team AnandTech was intense but hidden, and the usage of tasks harvests became a strategic secret.

From the start XtremeSystems went ahead, SETI.USA, [H]ard|OCP and Team AnandTech fought for 2-4 places, other teams formed an active, but backwarding peloton. Powerful buzzing monsters flying over project track, computed tasks, flew in pit-lane, pouring-out results, filled the fuel tanks by new tasks and raced again!
In the middle of the race, the set of computed results became so big, that it began to fall on the track and the race directorate deployed a validators safety car. After several minutes of restart, the race resumed and teams rushed to a finish gate! The fate of most places decided on finish line - Rechenkraft.net won 7th place against Russia Team, Crunching@EVGA overtook Czech National Team for 5th place. [H]ard|OCP had more bunkered tasks and made a great pursuit from 4 position passing by TeAm AnandTech and SETI.USA but XstremeSystems kept a large gap, managed a leadership to finish and won the race!

And it is time for the medal ceremony! Each team that won a medal can download it and and place on their website!

1st place - XtremeSystems

2nd place - [H]ard|OCP

3rd place - SETI.USA

4th place - TeAm AnandTech

5th place - Crunching@EVGA

6th place - Czech National Team

7th place - Rechenkraft.net
