Welcome back, Mark!

I'm trying to get the full total from reading the thread. It's easier than figuring it out from the database since there's no way to separate these donations from others (Other than the $1000 donations). I think that it's $9000 including the donations of less than $1000. Can anyone check my math?

Where it ends up will set the amount of RAM that comes with it.

Thanks for all your donations!

Eric


Eric,

Your math looks good to me! $9K exactly.

I see Mark's original $1K offer + 6 extra $1K (62466, 62467, 62468, 62470, 62472, 62764) + soft^spirit cheque for $1K + $200 + $400 *2 (62603, 62695, 62698).

Also, just for fun, I have a gtx470 running on a XP/32 AMD 2.61 GHz duo at 1089 Gflops but my gtx470 running on a W7/64 i7 930 2.8 GHz only gets 726 Gflops. WTF?

Russ


Have you tried downlaoding something like EVGAPrecision or MSI Afterburner

They will show you how your GPU is performing and allow you to overclock/underclock control fan speeds etc.

I've had a few recurring random lock ups varying from a few mins to half a day over the last couple of weeks myself.

I havent 100% tracked down the causes but these were the fixes.

http://setiathome.berkeley.edu/show_host_detail.php?hostid=5516356
Randomly freezing after months of working OK but with the screen still displaying. Tried various things, swapped GPUs and tried variouds combinations of the memory, upgraded video driver but still did it. Went in to BIOS and fixed the memory speed to match the RAMs spec and hasnt locked up since. I think the Auto overclock was pushing the memory too far.

Swapped GPUs (GTX470), upgrtaded video drivers and still the same. Checked and the fan speed on the GPUS had reverted to AUTO - I normally have it set to 100%. Set to 100% and hasnt locked up since.


John.

[Edit] Forgot a third one that happened yesterday. One machine repeatedly locked up (clock stopped) but then unfroze after a few minutes - keyboard and mouse not active so couldn't find out what was happening. Rebooted and been OK since.

I suspect the gremlins are at work ...........

I am with you Todd, Pappa wake up.
I am the go to girl when it comes to Cash donation issues and pretty clueless about hardware needs. But I can tell you, that the wish list server is about $3,000 under the current donations.
I have secured a promise that pics are will be posted once the new hardware hits the Seti Lab. Maybe the folks will we kind enough to let us know, what else will be needed to totally make this a Seti Volunteer Cruncher/Server etc pp.


I hope this will help towards the goal of the extra needed RAM or whatever you guys see fit to use it for.

I've gone for an early renewal of my green star for the worthwhile cause of this fundraiser.

Thank you for your gift of $1000.00 for the SETI@home via Mastercard on 09/03/2010.

Your confirmation number is: 62764

I hope you manage to get exactly what you need.

I have it set to shut down when the cpu fan speed drops to save the hardware, I had stupidly left some cables tied up with a rubber band which of course dried oit perished and snapped. Totally my fault whoops!


I did exactly the same thing on an i7 ASRock MB. I couldn't work out why the RAC of the machine was low and tasks taking forever to complete.

I installed the ASROCK monitoring utility which showed the CPU speed was cycling from 0 to 2.67GHz and keeping the CPU temperature at a constant 90C. Then I looked closely at the CPU fan and it had a power lead jammed in it.

Removed the lead, CPU dropped to about 50C and the speed remained constant at 2.67GHz.

It had probably been like it for a couple of weeks......... oops!

Even tho the server status page shows that several thousand Astropulse WU's are available, I always get the message "no Astropulse or Astropulse 5 jobs available - sending alternate jobs" or something like that. So ... what does one need to do to get Astropulse WU's???


Your results only show

SETI@home Enhanced 6.09 (cuda23)

Do you have

Use CPU
Enforced by version 6.10+ no

as you only seem to be running GPU tasks?

AP are CPU tasks so if CPU is not selected you won't get any.

Other options should be

Run only the selected applications
SETI@home Enhanced: no
Astropulse: yes
Astropulse v5: yes
If no work for selected applications is available, accept work from other applications? yes

Edit : Oops, on reread I see JohnDK already said as much.

It is a Belkin G Router wireless one which I have had for a few years



Have you bought anything new lately? Like a cordless phone that might be on or near the same frequency?

No I have not brought anything lately and my ISP have got no ideas I only seem to have trouble in July/August like line dropping before I had this problem something to do with re-sync the line. Maybe they are doing something at night with the exchange would like to go cable etc still on the same copper lines that have been in this bungalow before I moved in 39 years ago.


I can sympathise but not help much. I had a similar problem suddenly started with a Netgear DG834V2. Tried swapping with another borrowed Netgear DG834 and exactly the same. I have a work ADSL as well as home and now have a 3COM and a Zyxel installed and have not had the problem since. (The modem seemed to be working Ok - and could be pinged remotely but just periodically/randomly stopped sending data in and out) A restart made it work for a while.

I assume some change was made at the exchange which the old modems couldnt cope with (and no newer firmware for this version) but the likelyhood of getting my ISP to admit/sort anything out was highly unlikely so I took the risk and tried new hardware.

My ADSL is pretty poor - lucky to get 2Mb/s as we are a long way from the exchange.

The times I cleared my ghosts was on Friday mornings just after the project comes back up. Just set no new tasks, run down what you have left and detach/attach and redo your app_info. By then most of my work was done and I don't lose too much. It also gives me plenty of time to refill.

As for getting back on topic, right after the outage I jumped up to an all time high for me of ~40,000+ pendings. By the next day I was back down to ~25,000. I am now back up to over 30,000 though. Oh,and Questor, I have a bunch of your ghosts I'm waiting on and I think I've seen a couple from Todd too! :-)



Sorry you are waiting on my ghosts. The recent DCF ups and downs have meant I've ended up with way to many WUs after initially having too few. I'm therefore stuck with either keeping the ghost users waiting or if I drop my OK WUs setting a lot of other users back to another long wait for a new wingman.

Mine has not been working since the first 3 day outage. I was wondering if I was the only one affected. :-S

I get the page header ok but there's nothing below it

T.A.


Exactly the same as you have here. No truncation of data on the page - just no data at all , only the page header. Been like this for over a week now and pending was around the 800K mark. I 'assumed' that the increase in pendings because of larger caches and ghost units was becoming too big a hit on the database so they put in some sort of restriction.

Also had a quick check on a couple of machines last night for ghosts for the first time.
1. Reschedule showed 857 tasks in progress - web site 2020
2. Reschedule showed 882 tasks in progress - web site 2380
3. Reschedule showed 2800 tasks in progress - web site 4420

I'm going to have to do something soon to fix this but am loathe to disconect/connect because of losing what WUs I have.

though no doubt the newer WDDM drivers still have some room to mature until they reach similar efficiency to the XP ones, and under heavy loading cache effects will come into play as well.

Hi Jason.
What version drivers are you referring too? I'm currently running 3 tasks on a GTX470 under XP-32 using 258.96 drivers and V32_30_14 dll's with the V6.10 CUDA app. They are taking between 20 and 40 mins per task depending on the AR of the unit.

Is this the most efficient combination for XP? If not, what combination do you recommend ?

T.A.


Have you been running 3 tasks with the downlaod quotas in place? Just wondered what that does to the number of tasks you can download and whether you run dry during the outage. As far as SETI/Boinc is concerned you only have one device but are effectively getting through up to 3 times as many tasks but the completion times are for a single task. That should nicely confuse things?

I could be wrong, but I thought multiple Cuda contexts on one GPU is only possible under the WDDM driver model (Vista / Win7) and maybe only with cuda 3.0 & 3.1 builds (even less certain of that)

Jason



Tried this out this weekend. I am currently running 3 tasks on a GTX470.

The machine is using the downloaded stock apps (CUDA3.0) and is running on Windows XP 64 bit.

Havent done any benchmarking yet - just testing that it runs OK.

This is on an i7 920 with 2 GPUS and I have set avg/max ncpus to 0.4 which leaves 2 out of 8 free threads to help feed the GPUs (probably overkill as no maxed out threads and load times of about 20 sec per task).

This is with drivers 19775 and 25721.

Guys, pardon this old non-Fermi character butting in but I think I might see a problem or two.

He is installing a new 470 card in place of "older" (probably non-Fremi) cards. He has an app_info with 6.09 but probably doesn't have an entry for 6.10 Fermi so of course it will trash all his 6.09s. Try reading up on what needs to be done here http://setiathome.berkeley.edu/forum_thread.php?id=60079


As long as the new fermi app is referenced in app_info.xml as 609 then it wont matter - the workunit details will match with existing 609 WUs. OTOH if he has put an entry as 610 for the fermi card in app_info and removed the 609 reference then all 609 WUs will be trashed because no apps match.

Possibly post app_info.xml? - it will be easier to analyze what the problem might be. (an example <workunit> and <result> section for CPU and GPU would help as well).

Also have to watch that platform entries match - especially between CPU and GPU for when rescheduling. You might need a couple of very similar looking entries in app_info to cope with the possble combinations especially during the transisiton between the cards.

You could try moving work over from the GPU to the CPU.
Start with a small number, this should get you GPU work as well.

Probably now new work because of the number of errors you are getting.

An application has exited prematurely (unexpectedly) more than 99 times without generating a checkpoint, so giving up on that task.

Whoa........I told you I don't understand this stuff....LOL.

Are they both picking up valid IP addresses? Where would I check that?
I do notice now that they seem to be handing off back and forth once in a while....
One is active for a while, and then the other. Not quickly, maybe when one can't make a connection soon enough, the OS tries the other and then continues with it.





Either bring up a command prompt and run 'ipconfig /all'

or from the Windows start menu go to settings, network connections and for each NIC click on Status and then Support and it will show a screen with the IP address on it.

My mobo has 2 LAN ports......
One is a Marvell and the other a Realtek.
I used to just have the Marvell enabled.
Just for an experiment, I enabled the Realtek and installed the drivers.
Now when the rig boots, I have both LAN ports enabled.

Windows 2K seems to use only the one that is first initialized upon booting, which now seems to be the Realtek. The Marvell is active, and shows a little bit of activity upon booting.

Can Win2k be setup to use both to share the load? Or use one for one program and the other for another? Or will it only setup one internet connection at a time?


Are they both picking up valid IP addresses for your network (DHCP or static assigned)? If a port can't assign an address it will default to a 169.254.x.y address which may not get through your router.

However, see this note about Windows 2008 from http://en.wikipedia.org/wiki/Link_aggregation

Use on network interface cards

Network interface cards (NICs) trunked together can also provide network links beyond the throughput of any one single NIC. For example, this allows a central file server to establish an aggregate 2-gigabit connection using two 1-gigabit NICs trunked together. Note the data signaling rate will still be 1Gb/s, which can be misleading depending on methodologies used to test throughput after link aggregation is employed.

Note that Microsoft Windows does not natively support link aggregation (at least up to Windows Server 2008).[7] However, some manufacturers provide software for aggregation on their multiport NICs at the device-driver layer. Intel, for example, has released a package for Windows called Advanced Networking Services (ANS) to bind Intel Fast Ethernet and Gigabit cards.[8] Nvidia also supports "teaming" with their Nvidia Network Access Manager/Firewall Tool.



Most PCs now have gigabit NICs (1000Gbit/s) whereas my broadband router is only 100Mbit/sec so one NIC is 10 times faster than needed anyway so it never gets overloaded.

Some software e.g. Bitorrent clients will allow you to define multiple NICs to use but I cant think of much else that does.
