raspberry pi cluster versus fairymax

[flok]

Hi,

For fun and kicks I added "puppet master" functionality to my chess program. This allows it to connect via TCP to a chess program talking the UCI program (any will do: I connect it to a socket using "netcat").

This works pretty good!

For example: stockfish, toga2, fruit and glaurung all running on raspberry pies (700MHz ARM processors) versus fairymax running by itself on a Core I7 3930K processor (3.2GHz):

If anyone wants to play against it: it is now playing on H.G. Muller's website under the name "PuppetMaster".

Currently it has the following drones:

Code: Select all

# 192.168.62.254:55223 # stockfish on incontrol
# 192.168.39.2:55223 # toga2 on fork
# 192.168.62.129:55223 # fruit on weerpi
# 192.168.64.168:55223 # glaurung on detijd
# 192.168.64.18:55223 # minkochess on hetlicht
# 192.168.62.136:55223 # bikjump on slaapkamer

These are all raspberry pi's model b. "slaapkamer" is not literally in my bed room. It was supposed to be but I got complaints so now it is in the living room.

As you see only UCI capable engines although in theory xboard should work as well. Well more or less: the engine needs to support "setboard". And also gnuchess has this strange 5 second delay at start which goofs up time management.

Hello Folkert,

For some time I think riding a cluster, as a way to parallelize the my chess engine, but I have no financial resources "to spend only a hobby."

After reading this thread I started to have some hope, because with Raspberry Pis, the cost per node would drop considerably.

But first of all I need to know a few things:
- What operating system are you using?
- What is the mode you use to parallelize the application? MPI, OpenSSI, OpenMosix or another, what?
- How has your cluster nodes? I can only get a few, but I know I can go slowly adding nodes, while I develop the project ...

Another thing, how do you integrate the cluster to another network? (Obviusly I use a router, but the question is:) Do you run the engine in console mode in the cluster, with a GUI on another machine on another network?

I'm anxiously awaiting the arrival of the first Raspberry Pi , by postal mail , ordered this week . This will be the first own case , keyboard, mouse , TV and everything, the others are stacked in towers of Raspberry Pi.

best
Lourenço.

Hi,

My RPIs run Debian Linux but that should not matter too much.
What I do is: my DBP has a "puppet master" mode where it does not do any calculations itself but connects using tcp to an xboard or uci engine which is listening on such a tcp socket. Then it is the usual uci/xboard communication.
Further more: my cluster consists of all kinds of chess engines combined. Each is asked a certain position and then the most chosen (or a random one) is used.
So it is not DBP spreading its calculations over multiple nodes.
