question about clusters in general but really the Tyan T-650

ok this computer is a cluster of 5 mobos will 8 cores on each (2x quad core) so a total of 40 cores in the system.

My question is does the OS see all 40 cores or does there have to me some kind of interface application which does this or does the application have to know it is running a cluster and not multiple cores?

The reason i ask as i never worked with clusters before and if i have a multi-threaded application and will it run all forty cores, if the applications multi-threaded code is independent of the number of cores the more the better.

To me sounds like a good deal 20k for 40 cores. i build a 5k 4 core opteron machine a year or two ago for my boss so this is great prices

Each motherboard requires it's own OS, RAM, HD, and video capability, no matter how you setup your cluster. With Linux, they're called Beowulf clusters: link. I know nothing about whether it's even possible to do with any version of Windows, or how it would be accomplished.

thats was my orginal thought but seeing that there is a "head" node and 4 other nodes and only VGA and I/O ports are for the head node it makes me think it works like a 40 core system... but again i have no experience in this
