For those interested in the details of the judging platforms, below are some of the specifications for the target processors and the compiler software taken from some of the common query commands.  (Be aware that these specs may change without warning as the hardware or software is upgraded.)

The 32-bit version of (at least) the Intel compilers are available, too.  The version of Intel TBB installed is the latest 2.0 version.

If you have any special instructions on what compiler to be used for your submissions, be sure to make note of that in your build instructions.  The judges will make every effort to accomodate your request.

I noticed that no other intel libraries are mentioned.  If we use some other intel product, is it enough to tell you what we're using?  Somehow I don't think you want us to include all 200+ mb of IPP or some other product in our submission, but I just wanted to make sure.

PS. This is what part of the alphabet would look like if Q and R were eliminated.

Yes, we are able to get any Intel product (compiler, libraries, threading tools, etc.) loaded onto the machines.  It's always a good idea to note the use of something like this in your build instructions or a readme.txt file with your submission.  If we don't know that it's needed and it's not loaded on the machines, your entry may fail due to compiler/linker issues.

If you have some other library requirement, you should include the relevant files to support your app.  If it is free and dowloadable, let us know where to find it and we can attempt to install it ourselves. 

Think of your application being compiled and run by intelligent monkeys.  They can and will follow instructions for building and running contest entries.  But, if there are no directions, they will make simple assumptions (build and run default solution, type 'make', etc.) to get the codes built.  Anything beyond that and the monkeys get distracted by other low hanging fruit leaving your entry floundering.

Let we have a solution compatible with the both OS: MS Windows and Linux. Is it right that the program under Windows spends the same time as under Linux?

This is a question that the judges have asked themselves.  In the first problem and reports of runtimes in the second, the fastest runs have had sub-second times.  Thus, we've not noticed any difference between Windows and Linux. 

We are aware of the possibility of OS execution time differences and, should there be any questions about one OS yielding grossly different execution times, we will consider possible measures that might be needed to ensure fair judging.

The above /proc/cpuinfo doesn't seem to have ssse3 extensions... is that right? We aren't using Core 2 for this project?

I want to know the cores of the CPUs, because the number of threads should equal the number of the cores. Are there 8 cores? It seems like this.

You know when number of threads is larger than number of cores,although some work must be done to deal with the task assignment ,but the sametime more resourses are also be used.

So sometimes it seems that speed accelerates.

Excellent info, thank you!
