Hadn't any problems installing it on my laptop and PC too.

AFAIK, they are supporting Windows only.

To me, the current rental scheme is quite limited...to users with large wallets. Whilst it's fine to have a high-end pricing structure like this for "professionals", it seems bizarre to me not to launch with a low-end pricing structure at the same time (and not many months later).

Personally, I think it's pretty obvious that people should be able to rent the cluster on a "CPU hours" basis, perhaps with a minimum purchase level to stop "jokers" buying just one hour (e.g. 50 CPU hours for 50 Euros or something like that). CPU usage would only be used up when the Rybka cluster was actually evaluating a position (including ponder mode) and should probably be monitored to 1/100th of sec of CPU time (the amount of CPU left should be visible in the cluster interface at all times) - all other use of the Web interface should not incur a reduction in the CPU hours left.

Obviously, 2 cores of the Rybka cluster would use up approximately double the CPU time (though each CPU core should have its own usage exactly calculated and the total usage deducted from the CPU hours left - e.g. 2 cores may use 1.95 * the CPU of a single core).

Discounts should be offered for larger blocks of CPU hours purchased of course, but this scheme allows any "normal" person to join in and use it occasionally for analysis or even to play some games against it or against other engines and with prudent use, the 50 Euros could last a full year. Oh and "top-ups" after the initial purchase should allow as little as 10 hours for 10 Euros, since you might only want to extend the CPU usage a bit.

I also think that there should be free restricted accounts available (e.g. one minute of CPU on a single core for a free registered user - once it's used up, they'd have to register a new account), so that the user can see what they'd be getting for their 50 Euros. I mean, has anyone even managed to review the user interface for Rybka Cluster, complete with screenshots and a list of issues that need fixing? The restricted accounts would let mere mortals "try before they buy".

Could someone from the Rybka team please give us an update on where cloud Rybka for the masses is up to and specifically when we will be able to purchase by the hour?

Also Lukas's comment re the software beating R4.1 and others on 4 cores was helpful but quantified results would be welcomed.

i can probably offer much cheaper than this and i use houdini :-)))

Hello, I live in Brazil and I have a Macbook and would like to know if I can install Rybka 4 in 12 Shredder Classic.

Hi,

will Rybka Cluster be available in the "engine-cloud.com" ?

ya know you can pick up your own 64 core machine these days for under $8000 and analyze  till the cows come home  . would pay for its self in less then a month at those prices mentioned above
