1) Message boards : Number crunching : NVIDIA GTX 760 (maybe 2 with SLI ??) (Message 1435947)

Bill,

With 3 or 4 work units in the GPU, it was maxed out. What I've been watching is the thru-time. ie: How long does it take to complete a work unit. Net is that though they take longer, I seem to complete more work per hour most of the time.

I have one GTX760 installed and have configured it to run 9 GPU tasks at the same time. Seems to be doing just fine. It now consumes about 2500MB of the 4GB memory, uses 98% of GPU and 63% of Memory Controller. Temp stays in the low 60s C.

Does anyone have experience with a second duplicate NVIDIA board? Is there any advantage? Should they be connected with SLI and would that confer any advantage?

Thanks

3) Questions and Answers : Getting started : Administrator priviledge for BoincMgr (Message 1425610)
Posted 297 days ago by Profile Jim Wright
Hi BilBg and thanks for the suggestion. However, that did not prevent invocation with administrator authority.

Does anyone know how to kill the tag for required administrator authority appended to a link or other program invocation.

BOINC 7.0.64 (x86) is installed on W7.

Thanks,

Why does BoincMgr REQUIRE that it be started under Administrator privileges and how may I change that so that it will start smoothly and without operator intervention from the START menu (Win7).

6) Message boards : Number crunching : Communicating with BOIINC client. Please wait ... (I am STILL waiting ...) (Message 1377059)
Posted 422 days ago by Profile Jim Wright
It all started a several of weeks ago when BOINC persistently failed to communicate with the Seti systems. Something about an http error. I was running the then new BOINC_7.0.64_windows_x86_64. So I switched back to a prior version (BOINC_7.0.28_windows_x86_64) and the problem went away. OR did it? BOINC seemed to be O.K. and work flowed through both Seti and Milky-way. Since things settled down for a while, I left it alone and then got the bright idea to try 64 again. O.K. for a while, then the same failures reappeared for Seti. Milky-way continued merrily on. Switch back to 28, try 64 a few days later, back to 28, then 64 again. Now everything fails with the "Communicating with BOINC client. Please wait ..." message and nothing is happening.

I last uninstalled BOINC, went into the registry and removed anything BOINC, rebooted, reinstalled 64, failure, reinstalled 28, failure (a couple of times). I cannot get BOINC to function at all. There was also a complaint about the app_info.xml file not able to process Astropulse.

The system is AMD Phenom II X6 1055T, 8GB RAM, 64-bit OS, Windows 7 Ultimate with Service Pack 1 and all current updates. The GPU is NVIDIA GeForce GTX 465. TThrottle is installed and active to limit system heat. There is a long list of other programs installed and I use the system heavily.

HELP!!!

Thanks,

Thanks, you were spot-on. BOINC is now asking for CUDA tasks, unfortunately, there seem to be none available at the moment.

Posted 665 days ago by Profile Jim Wright
Hi,

Interesting, The JCW-OEM-11 machine has the Cuda processor and was the one processing only CUDA work until I uninstalled/reinstalled BOINC and rebooted.

The NVIDIA Control Panel tells me I have 352 CUDA Cores on the GeForce GTX 465 card with 4GB graphics memory and 1GB dedicated video memory. The Driver version is 306.23 and DirecX support is 11.1. The card continues to support twin displays (ViewSonic VX2450wmLED at 1920/1080. Stereoscopic 3D is not enabled.

What else would help you help me?

Thanks,
Jim Wright
9) Questions and Answers : GPU applications : CUDA tasks missing from my computer (Message 1291423)
Posted 666 days ago by Profile Jim Wright
Hi,

Well, I took the advice and lowered the "Maintain enough tasks ..." from 7 to 2, then 1, then 0 (a couple of days apart) and still received ONLY cuda tasks. Next, I drained my queue and uploaded all results, uninstalled BOINC, rebooted and reinstalled BOINC 7.0.28 (x64) with widgets 2.8.10.

NOW.....I am receiving ONLY non-cuda tasks. I did reinstall the copy of Lunatics (Lunatics_Win64v0.37_(SSE3+)_AP505r409_AKv8bx64_Cudax32f) that I had been previously using because a new one seems to be unavailable due to some licensing issue. Still no cuda tasks!

Any more suggestions would be appreciated.

Thanks,
Jim Wright

Hi, Actually, my problem is the opposite. I am receiving ONLY CUDA workunits and the six-core main processors are without any seti non-CUDA workunits.

My other machines (without CUDA) continue to receive seti non-CUDA workunits.

Suggestions?????

Thanks,
Jim
11) Questions and Answers : GPU applications : CUDA GPU workunits -- processing errors (Message 1228505)
Posted 817 days ago by Profile Jim Wright
I have updated the firmware to 296.xx and the errors continue.

Is there some way to turn off the process of sending CUDA workunits to my machine?

Seems it is just a waste of (a lot of stuff) to continue receiving them and then having them all fail.

Thanks,
Jim Wright
12) Questions and Answers : GPU applications : CUDA GPU workunits -- processing errors (Message 1226476)
Posted 821 days ago by Profile Jim Wright
I've noticed that quite a few of the CUDA workunits sent to me have unsuccessfull completion (computation error). Is it the code or my hardware?

The display(s) and Windows/7 are not complaining of any problems.

The unit is "NVIDIA GeForce GTX 465".

Thx, Jim Wright

I have a AMD Phenom(tm) II X6 1055T Processor plus NVIDIA GeForce GTX 465. The tasks page shows six tasks running simultaneously plus "0.67 CPUs+ 1.00 NVIDIA GPU". Check the Advanced/Preferences/Processor Usage tab and the percent to be used on multi processor systems. Set it to 100%. Also check your computing preferences at set@home.

I do have an observation that may need some fixing:

Workunit delivery on such a system seems to be severely constrained. I get only about as much work as can be processed in 24 hours rather than the three days I specified in my Computing Preferences. The amount of work delivered is insufficient to keep the machine busy over any extended (24 hours plus) outage.

It seems that a count of all workunits (both cuda and non-cuda) delivered and stored on my system is the constraining measure used whereas there should be separate totals maintained for non-cuda and cuda workunits. I'm seeing 7-8 hours each for non-cuda workunits and 15-20 MINUTES each for cuda workunits.

Therefore I would need 72 non-cuda workunits available to cover a 3 day outage. AND ALSO ... 288 cuda workunits to keep the cuda processors busy during the same 3 days.

When long Seti@home outages occur, I have to do work from other sites just to keep the machines busy. Luckily, Einstein@home is also of interest to me.

15) Questions and Answers : Windows : FORCED use of Internet Explorer (Message 907376)
Posted 1875 days ago by Profile Jim Wright
Why oh why do you now FORCE me to use IE when accessing information on my account. I use Firefox by preference and am very happy with it. Now, any access to the SETI@HOME sites ignores the already running Firefox window and opens one for IE. Tut-Tut, that is not a friendly behaviour.
16) Message boards : Number crunching : Astropulse, next workunit selection queue (Message 795760)
Posted 2182 days ago by Profile Jim Wright
Addition of astropulse workunits to work queues on machines having multiple processors has a small problem. Some adjustment in the order of selection on my local work queue would be nice.

ie:
Since astropulse (ap) workunits take significantly longer to process than Seti enhanced workunits, one of them (ap) should be shuffled to the head of the queue. This permits at least one ap workunit to be processed concurrently with the larger list of smaller/shorter Seti enhanced workunits.

The present method permits Seti enhanced workunits to be exhausted before ap workunits can be selected for processing. When multiple processors are available and workunit distribution ceases (frequently on weekends), the ap workunit soon becomes the ONLY workunit being processed and much of my available capability remains idle until regular distribution is restored (usually on Monday).

Thanks for listening,
Jim Wright
17) Message boards : Number crunching : Clone it (Message 660284)
Posted 2482 days ago by Profile Jim Wright
SETI@HOME has obviously grown so large as to be unmanageable in its present form. To fix this impasse, I offer the following suggestion:

--------------------

Clone the systems as follows:

1) Make an identical copy (or two or three) and independent installation(s) of SETI@HOME, each containing all the elements necessary for splitting, download and upload, etc. They could be named SETI@HOME_A, SETI@HOME_B, etc.

2) Each copy would process a chosen portion of the available data and then contribute the results to a common science/results database.

3) Any user would be eligible to subscribe to one or more of the sites at their choice.

4) Redistribution of the existing equipment may be possible thus avoiding acquisition of any more.

--------------------

The benefit is that if the two or more sites were indeed independent of one another, the likelihood of at least one being available at any one moment is near certain (except in the present (10/15/2007) situation when A/C is out or if there were a significant and lengthy area-wide power outage).

The user benefits by having a continuing stream of work units to process and avoids becoming frustrated due to many frequent and lengthy outages.

The project benefits by being able to take one site down for maintenance or upgrade without impacting a users ability to acquire and process work units from one or more of the others.


Please consider my suggestion in the hopes that this very important project may once again demonstrate its true potential for the furtherance of our scientific goals.

Thanks,
Jim Wright

Jeffrey,

Your response triggers a thought. What time format is the default on your system? Mine is "h:mm:ss.tt". Maybe that has something to do with it.

Hi, Interesting discovery ... when I set the first value to 19:00 (start time) and the second value to 14:00 (quit time), it did not take.

Then I tried other combinations, and none of them have worked.

I'm trying to suspend operations on one machine during the heat of the day, but proceed otherwise.

Using BOINC 5.10.13

Is this feature enabled???

Thanks,
Jim Wright
