2 instances of seti?

I was told to run 2 instances of seti, but not sure how to do it. I didn't find it on the help pages. Can anyone help me out? I tried just running it twice from the same directory but would get crashes. I assume what happens is that both instances are trying to work on the same unit.

Do you have a dual-cpu machine? If so, get SetiDriver and configure it to use 2 processes (and processor affinity).

Otherwise, running two instances of SETI on a single-cpu machine will do no good at all and may in fact slow it down overall.

Actually running 2 processes is the thing to do IF you r processor is a P4 with Hyperthreading. the easy way to tell if your processor is capable of hyperthreading is assuming it is a P4 it to look at the seti process in task manager. If it is only using 50% of the cpu then you most likely have a HT capable processor and should run 2 processes to fully utilize the processor. The easiest way to do it is to Use SETI Driver as your seti client front end which hopefully you already are. At the very top of the SETIdriver window you will see a line called maximum processes the number there should be 2 to run 2 processes. make that 2 and click the save config button and you should be all set.

Follow the directions in my sigline, that is the easiest way to set it up.

That's the best way to set it up using setidriver, though if you have a dual processor system and/or a p4c/xeon4c system then you should run 1 instance per real/virtual processor.
1 p4c should have 2 instances running
1 xeon4c should have 2 instances running
2 xeon4c's should have 4 instances running
4 xeon4c's should have 8 instances running
1 AMD (anything) should have 1 instance running
2 AMD (anythings) shoud have 2 instances running.

to run more instances of the client just change the maximum processes on the top left box in seti driver, you don't need/want to have mulitlple instances of setidriver, just the client.
 
Just to update you all...Yes I am running a P4 running at 3.2ghz. I have HT enabled and yes it was using 50% of the cpu. I changed it to 2 and now it's using 100 percent and crunching away. Thanks!
