Clusters?

[BRANKKO]

Can enyone explain to me and to others, something about Clusters?

What's the Clusters types?

How it works?

and eg.

-----------
I'm interesting for Cluster for SETI@home:
but no BeoWolf cluster, I need cluster when I can use all computers as one fast maschine (not meny 'slow's). I need onemaschine with power of all...

If you understand?

Do you mean a farm of PCs linked in a network or do you mean multi-CPU machines?

[BRANKKO]

I know how to build a SETI Farm, and BeoWolf (Linux) Cluster (a farm of PCs linked

in a network).

For this you need few PC's (Clients) as NODes, and one HEADnode (Server).
Every NODE running SETI Client separately:
eg. If you have 5 PC's with AMD AthlonXP CPU's and every of them need 2,5h for WU.
For 2,5 hours of computeing you will have compleated 5 WU's.

This is SETI Farm (build as BeoWolf Cluster).
---------------
And "multi-CPU machines" are something diferent... (Multi CPU OPTERONS... or Athlon MP...)
---------------
Cluster is a collection of interconnected computers working together as a single system.

I need some like HPVM (NT Clusters).

I want to connect few PC's to (G)LAN (Gigabyte LocalAreaNetwork).

When I run some application on HEAD_NODE it supouse to share CPU/Memory to NODES...
...so if I run SETI (for eg.) on HEAD_NODE it will compute one WU for short time:
Time to compute WU on HEAD_NODE = Time for compute WU on one NODE / Number of NODEs.

so if you have 5 HODEs time for one WU would be about 0.5h (30min) (becouse 2,5h/5nodes = 0.5 h)

Understood?

I need some cluster who will use NODES as one (Single) Computer.

Is this possible?
What cluster type I can use for this?
What OS need to be running on NODES/HEAD_NODE? Windows/Linux (FreeBSD/NetBSD)?

I'm not an expert, not at all, but i guess using Linux and with the right configuration you could do something like that, assigning a folder to each computer and then assign cooperative work, all the cpu's woking on the same WU, insted of one WU for each cpu. We usted to have a member here that could help you, and if i'm not wrong he had posted some info here in our forum about that matter, just try to seach a bit here, it may have some time by now...

Interesting...

[BRANKKO]

OK

All this amazing Computers, are 'just' SETI FARM's (SETI STACKS).

Enyone have some information about some other Clusters?
Not 'just' SETI...
