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.

For account creation please use a Crunch_4Science invitation code.

Results of the first half of the September 2019!
Dear folks!

Warm and sunny days are replaced by rains. September has come and deciduous trees take stock of summer. It's time for berries and nuts. But not only people need them! Numerous inhabitants of the forest will eat them during long and cold winter! Acorn will be a symbol of September!

Computers CPU comparison page
Dear folks!

Many computers with different CPUs perform calculations in each volunteer computing project, and a pair of results for each workunit gives information about the relative computing power of two "processor threads". Consequently, any project with data about successfully processed and verified results is a deep lake of information about CPUs. We tried to make a tool that turns this data into a more usable form and added a page with a comparison of CPU of an indicated computer with CPUs of computers that it faced during results validation.

We placed a "Compare" link in tables with a list of computers and onto the page with computer detailed description.
Comparison page contains two tables: the first table with data about the performance of a single thread and the second table with that converted into data about the overall performance of a computer considering the number of threads of computer CPU(s). Notice that most of the servers have two or more CPUs and, correspondingly, the number of threads reported by BOINC client and displayed into the table is larger than a number of threads of a single CPU in the appropriate number of times.
And, of course, this comparison is based on computing of RakeSearch application, with small consumption of RAM and usage of integer variables exclusively. But many other business workloads operate mostly with integers as well.

We hope that this data can be of help in some cases or can be interesting.

Thank you for attention to the project and participation!
