Ubuntu clock weirdness.

Thanks guys.

I had a bit of a nap this afternoon and woke up feeling hungry - which is a good sign. Had a tin of soup and a couple of bread rolls. Stomach cramps appear to have eased although I'm still doing a fair bit of sitting down - if you catch my drift.

Hopefully, tomorrow, I'll feel up to installing Ubuntu on some of the dedicated Folding rigs (or at least, trying to).

How would I go about installing a second SMP client on my Ubuntu? Is there something within the finstall script that will make it install a second client, and not just overwrite the first one?

I am getting around 7minutes a frame so just under 12 hours. Even if the frame time doubles it is less than a day to crunch two WUs. My linux install doesn't do very much other than browsing and office tasks.

Create a CPU2 folder and copy the fah5 and mpiexec files from CPU1 into it.

Then
Code:
cd foldingathome/CPU2
./fah5

and it should start setting up a second core. Reboot and see if both cores start automatically.

do you need to do run with -configonly and set the machine ID to avoid downloading the same WU you already have on the 1st core?
 
I'm not sure. I don't think so.

After
Code:
./fah5
the usual console config starts. You set the machine ID as usual through it.
 
ah yes you're right - I thought you were saying to copy the folder over :o

yup if you just copy over those 2 files then it won't have a config and will ask you to answer the questions again :)
 
Yea they're the two original unpacked files from FAH_SMP_Linux.tgz.

You could also copy over client.cfg and edit it to machine ID 2 rather than having to go through the console config set-up again.
 
Ahh excellent, will give that a go in a moment.

Just wondering what kind of performance I can expect from running two SMP clients on one machine. I notice that roughly 75-80% of each core is used, so would I expect a 20% increase in output?

I went from 6 mins a frame with one client to 10 mins a frame with 2 clients running so at least 20% gain.

Downside is that near 100% cpu usage by SMP means pc becomes VERY slow doing anything else.

Which cpu?

Does F@H on VMWare not still run at idle? Or does the virtual machine mess that up?
