AMEN, BROTHER! I have been ctrl-F'ing through 8 pages of nested/. comments, to see if there would be one reader to point this out. This guy is talking about web services, only taking out the distributed part;-)
Heya,
I recently released the first stable release of a GPL'd tool to detect DoS attacks coming through a router. It is called Panoptis, it can be found here, and it's using Cisco NetFlow accounting data provided by (most) routers. If you want, give it a try -- any feedback at all will be useful.
First of all, forgive my not-so-good english but it is not my mother language (I live outside the US & UK). So: It is true that I am not going to make any decision. I am a computer administrator, no darn executive. What I _CAN_ do though, is present my superiors with facts. This is what I am trying to find and why I asked slashdot users on the first place. As for what I know, yes I do know Linux is better than NT. I have a long background of Unix (or Unix-like, for that matter) based computers administration, and I consider it critical that this University's users have access to a high availability super computer. If this makes me a poster child, I accept this attribution. What I also accept is that my question was not clear as to the needs. What we need is a fail-proof number-cruncher. We need a system that can carry long computations (which could mean a beowulf cluster) and also be highly available (which I am not yet sure what it means). We have already setup a high-availability SUN cluster with 2 SUN250, but that will act as a web & mail server only, plus its cost is somewhat big. What I want is to built a system for the users to log in, and run their simulations & stuff. This should definitely be up on a 24x7 basis. Now as to PVM, with which I do have experience, I must let you know that it cannot be considered a cluster solution as it is not an integrated solution. PVM is just a parallel programming API, just like MPI etc. PVM can be used with most cluster systems (Beowulf for example), but that's all. What we need is more than parallel computing, period.

Would be a nice match, but Samsung now has Bada.
So is Bush. Sort of torpedoes your point.
Sure. While Guantanamo bay is full of people pressed with specific and established charges.
Get you facts right.

Readers may want to have a look at a GPL'd DoS/DDoS detection tool under development at the moment, found here.

Actually... ``Stuff that matters''. I mean it.
