Please Benchmark the Multi-threaded version of Freecell Solver

[Shlomi Fish]

Hi all!

I recently created a thread-enabled version of Freecell Solver, that uses 
several solver instances in separate threads. I'd like to get some indication 
of the performance of the solver with different number of threads on different 
machines. The instructions can be found below.

On my Pentium 2.4 GHz with 2.5 GB of RAM and 1 GB of swap, I'm getting the 
following results: (in seconds - lower is better)

{{{{{{{{{{{{
DUMPS/dump001:139.560144901276
DUMPS/dump002:115.644785881042
DUMPS/dump003:114.645025968552
DUMPS/dump004:118.50590801239
DUMPS/dump005:117.550628900528
DUMPS/dump006:119.174820899963
}}}}}}}}}}}}

So the optimum is 3 threads.

Anyway here are the instructions:

{{{{{{{{{{{
Requirements: perl-5.8.x or above, CMake 2.6.3, gcc, and a working pthreads-
devel library.

1. Download freecell-solver-2.27.2 from:

http://www.shlomifish.org/Files/files/code/fcs/

2. Unpack and cd to the freecell-solver-* directory.

3. Run "./configure -l tt".

4. Type "make" to build everything.

5. Run "bash scripts/time-threads-num.bash $MAX_NUM_THREADS" . The default
for $MAX_NUM_THREADS is "6", where 7 completely hogs my system. If you have
many CPUs and/or cores and are confident that raising it will not overload 
your
system, you can raise it.

This stage better be done when the computer is not loaded.

6. Wait.

7. Type "perl scripts/time-fcs.pl DUMPS/*" and copy-and-paste the results to
me with specifications of your comptuer that are as detailed as possible.
}}}}}}}}}}}}}

Any help would be appreciated.
