In same club thank you!

I remember using a K6-III and recall using silver ink to add a trace to CPU so two of them could be used in server motherboard to run two SETI units. Was a lot cheaper than buying the multi-cpu capable K6!

Just copy the BOINC folder to some other media and put it back right where it was installed before on the new disk. For your Windows 7 machines that would be C:\ProgramData\BOINC as the default location that BOINC normally installs to unless you made a different choice during installation. After moving the directory, check that you have permissions to read and write to the directory and sub-directories just to be safe.


Are you sure you can still do that on a new installation? I recall classic SETI stopping people from transferring their project results to other users as some people were selling the results on ebay or trading between users.

Absolutely, everybody does it all the time around here. Unless you are running BOINC << 5.0 or something.


I guess when they let BitcoinUtopia provide humongous BOINC credits for bitcoin cash, that pretty much put an end to any credit trading morality.

I have used acronis true image in these exact circumstances to clone a disk. I think they have a trial version. As I recall Seagate (or maybe WD) provided a lame copy of Acronis that was good for cloning a disk in their retail version.

You must run a surface scan to repair any file problems before booting the acronis (or whatever) CD and starting the clone process. Be sure to remove the old disk before rebooting.

[EDIT]

Just realized you want to reinstall 7.

I highly recommend the following:

First, fix any file problems, then download and run that still free upgrade to windows 10. You can select "keep my settings and programs". I have converted all my 7 machines to 10 even really old ones and they work fine. Windows 10 has a "reset" feature that reinstalls itself to a "clean machine" and where you get a new serial number and Microsoft remembers it for you (if you have a Microsoft account). That free 1 year upgrade seems to be good for life or until Bill Gates decides otherwise.

Post:
I tried this on my surface pro 4, the one that does not have the fancy graphics chip, and it worked OK for those BOINC projects that use the Intel gpu. It constantly ran hot even with tthrottle, and I removed it. Boinctasks is the only boinc type app I used on it now. Quick sync can be enabled on some surface Pros' and DvdFab's bluray copy program can use that for video conversions. Unfortunately, you need to buy a bluray portable player but the difference is minutes instead of hours.

On another subject, I just discovered that my Dell 730 system is capable of 16gb of memory even with a core 2 duo. Seems like NVidia did something right with their 790i chipset. I wrote to an eBay dell distributor who had sold 8 of those 730 motherboards at $48 each and told him they come with a bios supporting free install of Vista and can handle 16gb using 4gb sticks. I bought one before I told him that.

Unaccountably, my boinc settings memory usage on one of my systems was set for only %15 available for boinc. I saw the message "gpugrid unable to run insufficient memory" or something like that and I went to settings and discovered the %15 and changed to 100. I checked a couple of other systems and found one that had at least 700 message from SETI about 30 second delay. That system had 4 gb of memory and I added two more sticks and never saw those again. YMMV.

HOWEVER, any SoG 8.20 tasks fail with "postponed 30 seconds" message in task log, and will never start.


I have seen this before - 100's of postponed 30 second messages and only a little work done.

You need to allocate more memory to the projects. Set boinc use %100 or, in my case, I had to also add more physical memory.

Thanks! This worked. I am setting up the win7 task scheduler to perform this function. Two tasks that were hung actually completed successfully after restarting. One was hung for 5 hours. I noticed that the run time reported by the project did NOT show 5 hours, only the normal 40 or so seconds. Apparently it did not exit properly after successfully completing.

Anyway, you are correct as the problem should be addressed by the project if they would get around to it.

I probabloy should have posted this at the boinc client forum.

There is a discussion here but I cannot make sense of it.

My Problem: I have tasks on my pair of 5850s that should take 20-40 seconds. Occasionally one hangs and almost 2 hours later that exit timeout error occurs and that GPU finally starts crunching again. I want to somehow set the expected time to about 2 minutes and it seems there possibly is a way to do it by estimating the flops usage but I don't understand claggys instructions.

There is a discussion here on how to set a timeout in the project job file but a client restart erases the XML file and I am back babysitting the project in either case.

I just noticed that a system that has gtx280 and gtx460 is being assigned CUDA_FERMI and both GPUs are getting work. I assume that is OK since I don't see any errors. As I recall, gtx280 is not a fermi.

13) Message boards : Number crunching : cuda23 never showed progress on BM (Message 1107449)
Posted 18 May 2011 by Profile BeemerBiker
Post:
Different system, dual opteron, same problem: no progress unless the task is restarted:



This system has two cards: gtx460 (d0) and a 9800gtx (d1) and is also running that 275.27 and 6.12.26

the above is from boinctasks otherwise the progress would have shown 0.0 %

[EDIT]
I suspect a driver problem. I just logged onto that system, vista 64, and had to dismiss two nvidia driver reset warnings that popped up. A driver reset during crunching possibly is causing this to happen.

Here is another one that hung (never progressed) until I restarted boinc:

From BoincTasks (note the 847% complete as shown by BoincTasks) and runtime of 1 hour, 22 minutes.



This is the same image but from Boincmgr 6.12.26



I restarted boinc and immediately progress was shown under boinc. The task completed in 8 minutes as shown here



I updated the project and the result was posted here

This job ran AFTER I upgrade to that beta nvidia driver 275.27

From looking at the work I see no indication of the over 1 hour run time that unaccountably occured. Something is amiss. This system has only a single gtx280 and a q6700 cpu and is used exculsively for boinc (no games)

This message board was down while I had the same problem with a milkyway job. The milkway jobs were open_cl as opposed to cuda_fermi whatever that is or cuea23. I posted the same problem over at milkyway where the suggestion was to upgrade to the beta driver 275.whatever

Anyway it seems that if I stop boinc and restart then the job either completes immediately with success or restarts at 0.0 and runs the normal 15 or so minutes before completing successfully. Since milkyway deletes results almost as fast as they are posted I can only guess that it was validated. I had a 3 hour 30 minute job (3:25 cpu time) that completed within 20 minutes from scratch (0.0 %) after restarting boinc.

Discussion here

I think the job that had the problem I posted about seems to have problems at all the wingmen. However, I have observed jobs completeing succesfully after restarting boinc, both SETI and MILKY

I have upgraded all my systems to that 275.latest&geatest and will see what happens.

I aborted this task because it never showed any progress after 13 hours of runtime. BM showed 0.00% complete while BoincTasks percent complete varied around 1400.00% It was the 1400 that caught my attention.

This happens very rarely, but when it does it consumes a lot of run time before I notice the problem.

I would think that any project using a GPU for co-processing should implement some type of timeout for "no progress".

I do not know why BoincTasks reported non-zero progress of %1400 for this task while BM showed 0. This indicates that BoincTasks spotted something that BM didnt.

I scrolled the screen down to where the gpu voltage is displayed and wrote the image back out. It is only 1.1 or so volts, not 12. Hit CTRL-F5 if in IE to refresh the gpu-z image. So about 1.1 * 40 amps = just over 44 watts peak. 40 amps * 12 would be too high a wattage and that made me go back and re-examine gpu-z I assume there is significent efficiency loss converting from 12 down to 1.1. I am no engineer but I know ohms law. Since this unit is used only for boinc then the video load is 0.0 and I assume the current requirement is much more if gaming.

Post:
Ok, I have a question, it came to me while playing around with the idea of building one of these just for fun, to see how it performs. I see that the Atom 330 boards list an external power supply, something like 65 watts or such. It says it has a 16x PCI-E slot, and the question I had was isn't there some spec about how much power a 16x PCI-E slot is supposed to put out, because if one was thinking (just for fun) of putting in, let's say, a Nvidia GTX 285, obviously you would need an external PS to power the 6/8 pin connectors, but isn't there a certain minimum amount of power needed to power the PCI-E slot, and is a 60 some watt external PS enough to do it? Or hadn't they thought that someone like me would be crazy enough to attempt to put the 2 together? ;)


You could rig a powersupply like this one. I added a 12 volt relay that switched the power supply on when the primary powersupply was turned on. This saved me a few bucks as I had a nice 400 watt supply and didnt want to get a 750 watt for my two gts250s. I bought two 8 pin molex extension cables, cut the female ends off and connected them to the output of the power supply.

NOTE: If you do something like that, be sure not to connect any pci-e cables from the primary supply to the same card(s) that have that aux power or you can get reverse current flow transients. The remote control relay is also a must or the reverse current flow will not just be a transient.

I do not have a wattmeter tho I do get a bill at the end of the month.

However, I do have gpu-z and it looks like I am drawing between 21 and 41 amps while crunching seti. I recall milkyway gave a higher average like 32 - 40. Collatx did not pull as much as milkway I think.



The above current is for my gtx280 with its 64nm core size. I would be interested in what your gtx285's are drawing as they have a smaller die.

Not all nvidias have current sensors. I cant get a valid reading on a gts250 or a 9800gtx+
