Load Sharing Software


I'm looking for a simple solution to load sharing software that can be run on multiple servers. My situation is that we have 3 new servers running(core i7, 12gb ram) and I've been asked to look into load sharing so that the 3 servers can work together.
At any time we have anywhere from 5-10 people connected to any of the 3 servers running compiles and other jobs so having the jobs shared across all servers will speed up the processes.
I've looked at Grid Engine 6 for about a week now and have had very little success getting it running(their manuals must have been written by Nortel). I've looked at some others as well here: http://lcic.org/load_balancing.html but it is a bit intimidating looking into a type of software I've never used before.
If you have any software suggestions or maybe a simple guide to working Grid the help would be appreciated.

Grid can be intimidating, but it does work well. Ultramonkey is another solution too, but do be aware that your application(s) need to be tailored and written to make use of a grid, and submitted through the grid 'controller'. If that's not an issue, you will definitely see benefits to it.

Depending on what you want to do, you may want to look at something like Radware, which can present one IP address to the world, but send different sessions to different boxes, based on rules. First user goes to box-a, second to box-b, etc., and it'll watch to see when folks drop off, to open up a new session. What kind of service/app are you using?

If you find anything useful for load sharing compiles, please update your thread to help others.

I haven't found time to work on it, but I also want something for load sharing compiles. I wrote a thread with more details about what I hoped to do:
http://www.linuxquestions.org/questi...please-724215/

I expect you'll need to discover the answers to some of those same issues. If you do, I'd appreciate your sharing them.

As far as I know cadence tools, quartus and xilinx are the main things used. I'm not sure if any of those programs are built to be used with Grid and if it's possible to do it myself I wouldn't know where to begin.

Sounds like I misunderstood what you mean by "compiles".

I've got a list of the programs that are needed to be run with load sharing, I am unsure where to find out if they are supported or not, maybe you guys know or can point me in the right direction.
Here are the programs:
Quartus and ISE (xilinx), NCsimulation, VCS, Modelsim.

I also wanted to point out that the 3 main servers mentioned in the OP are running Intel i7's with 12GB of ram while most of the workstations are on Xeon cpu's with 2GB-4GB of ram. Would using load sharing give a performance boost on the servers? On the workstations?
