Linux Dual Proc Help Please.

[HayHauler]

I have a PIII 933 mhz dual processor machine running RedHat8.0. I am currently running 2 instances of S@H in 2 different tty's, in 2 different directories. My question is this: How can I tell if the processors are balanced between the 2 S@H's? AND How can I configure the S@H's to run on separate processors? I am new to Linux and know just enough to be dangerous. The only other Linux box I have is running a 2 way interface from the internet to a Ham Radio AX25 packet cluster(running DXSpider) and a BBS. (which took me about a month to get configured and running).

do a 'top' command. what you should see is 2 instances of S@H, on the first 2 lines, each with 95%+ of your processor umphhh.

how did you get seti to run on rh8.0?!?, I've been trying for a month with no luck.

also wouldn't it have been easier to have one instance of seti and have it processing 2 WU's instead of 1? If I understood right, the processing is split between the two, and in smp, is split equally between the 2(or more) processors. The way you described having it set, would likely have both WU's being processed by your cpu0, and cpu1 doesn't get touched.

You can't with the standard kernel in RH 8.0. The ability to set affinity is introduced into the kernel somewhere in the 2.5 series. You may be able to patch the 2.4 kernel (I don't remember), but it would still require a kernel recompile.

Well, I have the standard kernel, 2.4.2 ? something that I updated 2 weeks ago, at RedHat's suggestion. I am running 1 S@H on tty0 and 1 S@H on tty1. They seem to be crunching pretty fast, but I cannot verify the load on the processors. I will try the 'top' command and see what I can find out. I will report the results back to the thread.

Thanks Mgpaulus, the top command shows that both CPU0 and CPU1 are fully utilized. Like 97 to 99% ! Cool, I guess that I am crunching as fast as possible.
Is there any way to make it faster?

As much as i hate to say that: INSTALL WINDOWS

The Win client is much faster!

I don't know if it still holds true or not, but actually running the Win CLI using WINE in Linux was actually the fastest. If she was around, Poof could tell you.
