| Post subject: | cfrm cloud computing |
Hi guys congratulations for the forum and thanks to spears, some of my classes are based on his code. I'm not an expert of computer science but i've developed a version of cfrm applied to poker in java, that seems work but i can't run it on my limited machine so i need some advices. I need to use an array were i can put the result of every hand confront given the flop, dimension are 1326x663x52x25 where i need to save three possible states (win, loss, tie). On java with the less expensive primitive type (byte) it costs 1,15gb , in alternative i can use bitfields of 2 bit for 286mb total. Then i need to use another 450mb for the Paul Senzee perfect hash table to build this table and another 300mb for the objects of my programs. Then my programs is completely a recursive tail call to itself (one for every brunch of the abstract game three) so i can take full advantage of multiprocessors architectures. If i want rent computing power in cloud whats kind of specifics i need to check? Have you any site that you would recommend? |

I'm impressed that you get the problem to fit in so little memory. Hardly seems worth worrying about putting a 1GB app in the cloud. The answer really depends a lot on how long you expect your app to run for. I also have reduced the memory to something quite small, but I've come to the conclusion it is cheaper and easier to buy a couple of used games pcs, than to use amazon ec2 |

I agree with spears regarding using EC2 instances. You will be better off buying used servers. You can get a dual quad core Xeon with 32 gigs or more for less than $150. If you are insistent on using the cloud I would start with the typical companies: amazon or google. I believe both offer free versions with limited resources or time. |

When I was working on cfrm, I bought a server off of ebay with 72GB RAM (HP DL380 G5, 2x Xeon L5520) and adapted my abstraction to fit into that memory footprint. But that would set you back about $1k. Made my code in C to optimize memory and performance. Code and server is collecting dust now, but provided a very profitable ROI. |

Thanks for the answers. Anyway my app need of 1gb of RAM but during the excecution it need to save houndreds of gb on the memory. I took a look at the free version of amazon web server. For now i've decided to do the first version of my bot using sampling to estimate the parameters that i need if it'll have some potential at the table i'll invest more on it. |
