Update

OK, going back to the older CUDA client seems to crash Second Life more so I've switched back to the x41g client. I have raised a bug issue with the Second Life viewer team and will see what gets resolved from that end.

Cheers

Mark


I prefer the phoenix viewer myself. Perhaps it, or one of the other 3rd party viewers, doesn't have this issue?


But does phoenix viewer have a linux version?

Both of their viewers do seem to support linux.
Here is the link to their site:
http://www.phoenixviewer.com/downloads.php

Over the years I found the 3rd party guys to have a lot more stable version of software and actually more willing to fix issues.

It may not fix any issues with running CUDA but I figured I would put it out there in the event it does.

Update

Hi team

Yes I am actually running the latest Firestorm Viewer.

The crux of the issue after some discussion is that the user selectable texture memory limit in the viewer does not account for how the SL viewer uses all the VRAM - the texture memory part is only a small part of the VRAM usage for the viewer.

So basically the SL viewer will use up as much VRAM as it wants regardless of the texture memory setting. So I have to consign myself to the fact that Second Life is going to hog the VRAM and contend with the CUDA client for resources.

Back to the experiment .... wondering what else will pop up :p

Cheers

Hi Team

Well my computer online time is going to be sporadic over the next several months so for the moment I am abandoning the experiment. I will be running 4 SETI processes on the cpu and 2 on the nvidia 580 graphics card. So for now i will just crunch on.

The server and data supply issues have also made getting any form of consistent baseline pretty much impossible - so not sure if those issues will get better over time or not.

Bottom line is however that this rig is way faster than anything I have used before. I have already crunched 15 times more work than I have in the preceding 11 years of doing seti - thats just crazily amazing :-)

Cheers

Mark.

Hi. May be a dumb question, but how do you consistently set 4 CPU and 2 GPU tasks. I would like to be able to better control my resource utilization (especially across projects) and can't figure that out. I am using Boinc Account Manager and it permits one to set resource share across projects but the sync with clients doesn't seem to work consistently and the granularity (i.e. able to specify 4 CPU and 2 GPU units) isn't available. Thanks in advance.

Hi Chris

Simply set the number of CPU's to use as 50%, that way it will run on 4 of the 8 cores.

As far as the GPU side of things I am using the optimised CUDA program from lunatics ( http://lunatics.kwsn.net/ )

In the configuration (app_info.xml ) file for that change the setting that says:

---------
<type>CUDA</type>
<count>1.0</count>
--------

to

-------
<type>CUDA</type>
<count>0.5</count>

---------

This will cause 2 seti instances to run on your gpu.

Hope this helps :)

Hi,

I'm running my six physical core i73930K + one NV560TI-448 with
1) hyperthreading on (12 logical CPUs)
2) use 50% of the processors (6 tasks for 6 physical FPUs, no context-switching)
3) a single NV560TI-448 with 3 work units at a time (count=0.33) (3 logical CPUs serving GPU memory needs + needed CPU logic for GPU tasks)
4) 3 logical CPUs left for OS, GUI, etc.

I'm satisfied with the 24/7 Seti RAC around/above 40000. (HOSTID 5643864)

I've just started with the lunatics APV6 so I can't tell where the RAC is going to level out. I also had a complete reinstall of the OS/Seti a few days ago due to a failed attempt to upgrade to fedora 16.

Here's mine running about 6 days on 4 cores, with 1/10 of a day of work setting.

Then the last 6 days begging for 10 days of work on 8 cores, just got it yesterday.

http://setiathome.berkeley.edu/show_host_detail.php?hostid=6593763

ie..without any tweeks.....yet. I'm banging. Compared to gett'in 3300 pts in 10 years....I got 42,000 today.

I'm really interested in how to get 40,000 a day out of my I7.

But don't have a clue how to get it.

Right now I'm second in RAC in my group, up against a guy with 34 computers, I have 4. And I'm out processing the other 98 active in the group.

Any suggestions would be welcome....If I have to put up another I7 2600K at the office I'll do it just to take the 34 computer dude out.

I'm sure he's on a network at work, and this is my home server HTPC network up against him. If you have any ideas make them simple, because I am stupid.

Any suggestions, I've been at this since 1999.....off...and...on.

What a marvellous and commendable attitude !!!!! :)

If you look at his computers, they are all i7 s,but the RACs are low on each machine,
because he doesn't have any graphics cards ( apart from 1 old one ).
Don't buy another i7 just to try and beat him,it won't work.
You have a few decent graphics cards shared between your computers,and that's
where the credits lie.
If you read the lunatics installer 0.40 thread by Richard Haselgrove, it may be the
best short term solution, but even then with your set up,you won't quite get there
and beat him.
Instead of buying another i7 computer, you would be better off spending that money
on 1 or 2 new ( or used ) graphics cards,and installing lunatics 0.40 .

I have a basic i7860 coupled with an EVGA 460 and my RAC goes up to about
22,000 when it has been running for a month or so using lunatics optomised apps
(I have been away so my RAC has fallen,but it is on its way up again).

Your 550 should get roughly the same( or slightly more) and your 560 should get
a bit more.

If you do buy new graphics cards check the power required to run them,compared
to the PSU in your computer.

Wait until a few more people have replied before you do anything,as they will be
more knowledgeable than me ,and may have different ideas.

The above is just the solution I would use. :)

Wawasoo,if you are letting Windows put your monitors to sleep using that nvidia driver version then you' are also putting the video cards to sleep.

Either disable Windows putting the monitor to sleep or go back to a pre 295.xx video driver. ;)

Cheers.

As mentioned already using the 3rd party optimized applications from the lunatics would be a good place to start if you are up for that kind of thing. The downloads page is here if you have trouble finding it.

One of the advantages it would offer is to run more than 1 task at a time on the GPU. Which may or may not be something you would want to do. Everyone has their own needs out of their computer(s).

The top guy in your group has a big mix of machines, which oddly looks a lot like my list, & are probably dedicated crunchers. So depending on your crunching duty cycle you may or may not be able to take them even with superior hardware.

It's a home network. A WHS with 30TB of storage Pumping Media arround the house on demand, using Windows Media Center, Media Browser, and Meta Browser 2.0. Uses about 2% of itself. So I can donate at lot of time to Seti.

Any good threads for Lunatics for idiots?

I put that lunatics software on my slowest machine. Left all the tick marks where they were.

Let it install.

Looked at a project....closed my eyes....blindly counted off 10 seconds.

A minute of task time elasped......then I watched it with my eyes open...

Happened again.

As they just did their v0.40 release recently there is the thread Lunatics Windows Installer v0.40 release notes.

One of the key parts to note is: "How to use the installer:"

With the opt apps the key is matching the app to the processor abilities. Which is most cases for multibeam (Seti@Home Enhanced) tasks on Intel hardware is SSE3 or SSSE3x.

If in doubt. Ask a silly question. More than likely you will get a silly, but helpful answer.

Stop SETI and close BOINC Manager. Go into your program data/BOINC/projects/setiathome. Find your app_info file and open it with notepad. scroll down through it until you find a line marked <count>1</count>. Change that to .5 for two work units at a time or .33 for three at a time. You should find the <count> entry six times if you are running a 64 bit system. Change all of them. If you are running 32bit it will only be three of them. Start BOINC Manager and you should be good to go.


EDIT: okay, Hal got me thinking. I thought you had it running okay and wanted to run more than one work unit on your GPU. As he said, it depends on the instruction set your system has. You can use CPU-Z http://www.cpuid.com/softwares/cpu-z.html to figure out which one you need. Your I7 will probably be able to use sse4.xx so you should have checked either that or ssse3. They will probably be pretty close to the same speed.

Honestly....I ain't touched shxt. I just cut the count from one <1> to .33.
