Love 6.30 SMP Client!

Postby Knipfty » Fri Aug 13, 2010 3:23 pm

I have now converted 3 machines over to the new client. My PPD has soared!

I went from about 1,400 PPD (all single CPU clients) to about 10,000 PPD. Yesterday I turned in a little over 15k points!

My best month ever was a respectable 94,000 points. As I write this, I have 71,587 points this month and am on track to hit about 250k points.

I am knocking on the door to 2 million points (it has taken me almost 3 years to get hear). I could be easily at 3 million before the end of the year.

My SMP machines breakdown like this:
Dual Core Laptop ~2,000 PPD
Dual Core with HT Laptop ~ 2,500 PPD
Quad Core Server ~ 5,000 PPD

I am also trying to upgrade an older dual core E4400 to a quad core q6600. May be another week before all is in place. So that may add another 2,000 PPD.

That's great! But why weren't you running the SMP client before now?

I dabbled with the older SMP clients. They almost always gave me trouble.

The server listed previous, was not a machine that I monitor on a regular basis. So I stuck with the single clients. I started thinking about SMP again when I got a new laptop (dual core HT). I just figured I give it a try. That was when I learned about the bonus points. So I figured, what the heck and threw the client on the other laptop. Both have been rock solid. So I threw it on the server Tuesday night. I will check on that server tomorrow, but judging from the points, it is working just fine.

For any multi-core machine that runs 24x7, the SMP client is recommended . . . except for those with the very slowest chips. We all suffered through the days when SMP really wasn't working very well and it appears that those days are now behind us.

I'm loving the SMP client too :D

I was running just 2 GPU clients on twin GeForce GTX 260 cards.
The longer the pc folded (it folds 24/7) the less PPD each GPU made. eg. WU 5765 for 353 points would give 6777PPD after a reboot, but would slow down to 5700 after a few days... so i'd have to reboot every 2 or 3 days. :? :?

With the addition of the SMP client, my 2 GPU clients have gotten more stable... :o :shock: :D

And it has been keeping up the same pace now for a week or so and i've not had to reboot to get the speed back up. :D :D

This is really strange. I started with Classic Client + GPU2 on Nvidia and never ran into this issue. I then used 2 Classic Clients + GPU2 Client on Nvidia and never had any issue. I then ran SMP2 (6.29) plus GPU2 on Nvidia and again no issue. Finally, with SMP2 (6.30) and GPU2/GPU3 Clients on Nvidia, no issue.

Can you please describe more about your setup so we can identify this unique issue (I did read it somewhere else in this Forum but can't remember who posted it)

Slowing GTX 260s is a well known issue, you need to force 3D clocks. Mine used to do this all the time.

Oh and yes I do like the hassle free SMP setup has allowed me to switch over another quad that was previously doing multi classics as I didn't have administrator password for.

Oh, if that's the case, then I consider my self very lucky as I have a GTX 260 and it never gave my any slowdowns or anything. Only <5 EUEs due to Windows Update and my high OC.

My GPU's didn't down clock to the 2D settings... the same work unit just got a bit less PPD after running continuously for a few days.

My current folding rig has a "Asus M3N HT Delux" motherboard with an "Athlon 64 x2 6400" CPU.
I'm running 2 GPU's folders on twin "GeForce GTX 260" cards.

I wasn't running a classic client with them, just the 2 GPU clients... I can let you have the full settings, if you need them, when i get home. :D

Sorry, this is the described downclocking behaviour, 1-3 days speeds reduces, which is fixed by a restart (identifying feature) and the same thing happens again. This is not noticed by those who frequently restart their systems.
If you want to stop this happening you can follow the guide I linked to.

I should have said that the clock speeds reported in GPU-Z didn't change to their lower 2D settings. :)

However, whatever the reason... using the SMP client alongside the 2 GPU clients has sorted the problem. :D

Sounds like something was going to sleep / standby, then adding a work load to the CPU or HD keeps things active and awake, then no slow down.

Any power saver settings on the PC?

It's always great for us to hear feedback like this. My hope is that the v7 client will (once several current issues are ironed out) will get a similar reaction, as our goal there is to make it easy for donors to run SMP, GPU, etc, but still allow donors to have lots of flexibility and options as well if they would like to tweak their set up.

Nope, i deliberately switched off any screen savers or powersave options in the OS and in the drivers for the two GTX260's to try and ensure no slow downs :D

If there is anything you'd like to know about my setup, please let me know. I'm just glad i can leave it alone even more than usual. :D

I have 17 systems running the Core A3 EL-WU's via SMP 6.30 and all are running just fine. My computer room is running HOT!!!!, about 95 degrees right now.
