Hi all!

A good amount of new WUs will be around for the next weeks in the long queue. The systems are called hfXA_long and will provide around 90000 credits each.

Thanks and Merry Christmas to all!!
Noelia

My computers just downloaded a couple of them. They seem to be very long (looks like about 14 to 16 hours before they finish on my computers.) GPU usage is 90%+ on both windows 7 and xp. I hope the upload files aren't too big, so I don't get an error for that.

What exactly are we crunching with these Wu's, in layman's terms please?

Merry Christmas!

I hope I am wrong on this but it looks like the output file for these work units are going to be larger than 128 MB. After one of the units was 25% done, the 1x1_10-NOELIA_hfXA_long-0-2-RND6540_1_4 file was about 35 MB in size, at 33% done it was about 47 MB in size. If this projection holds when the file will be 100% done, the file will be about 140 MB, too large to upload, unless you raise the size limit of the upload files. I hate to see an otherwise successfully completed unit, error out like this.

This error occurred before:

Message 27752 - Posted: 20 Dec 2012 | 11:08:57 UTC - in response to Message 27751.

I have increased the upload size to 200MB now, but this will take place only on new results. I guess it's at the border line between 128MB (the previous limit), so it depends on the compression.

It's our mistake as the internal test did not complain, but now it's a bit of a problem to cancel them.

Ok.
We have checked in the DB. There are 87 failures like this and 1800 successes for this batch.

As I said the problem is that the submission script did not picked it up.

All new results will have a limit of 256MB.

gdf

Starting from the new application in January we expect to upload much smaller files. 1/3 of the current size.

Can you manually increase the limit or at least see how much it is?

Is your version of the boinc client compressing the files? I don't understand why for some it works and for few it does not.

This is very very bad.
I have only one successful NOELIA_hfXA_long task (it was the first one) and 9 failures 8 of the failures are because the upload limit exceeded.
Maybe the BOINC manager (on Windows) has this 128MB upload limit, so it couldn't be fixed on server side, since the increase I've got this error again.

And for sure on my other computer failed one as well.

Is there a possibility, to identify the WUs GDF has corrected? The failed ones took me over 11 hours to crunch.

ERR_FILE_TOO_BIG -131

One of the output files is bigger than the maximum set by the project for upload.
BOINC will not try to upload this file.

Solution: Go to the project's forums and report this behavior.

Nothing can be done client-side. I don't know if any modifications done server-side (I guess that a restart is needed) will actually reflect on already distributed workunits...

[EDIT]

I have a wu crunching since ~7 hours and I hope I will not lose it.... I found inside "client_state.xml" some lines about the "name_of_the_wu_4" which is the larger of the output files made while crunching: <max_nbytes>128000000.000000</max_nbytes> will change the value to a much larger one, restart boinc and see what happens...

So the situation is this one.

All the new WUs SENT after we have made the change this morning are ok.

The ones that were already queued in your client before this morning in Barcelona have a 50% probability of failing the upload, so cancel them.

Check this file in client_state.xml

I have a wu crunching since ~7 hours and I hope I will not lose it.... I found inside "client_state.xml" some lines about the "name_of_the_wu_4" which is the larger of the output files made while crunching: <max_nbytes>128000000.000000</max_nbytes> will change the value to a much larger one, restart boinc and see what happens...

I did it, and it's working!

1. Exit BOINC manager with stopping scientific applications
2. Locate the client.xml file and open it with a text editor
-- On Windows XP: notepad.exe "C:\Documents and Settings\All Users\Application Data\BOINC\client_state.xml"
-- On Windows 7: notepad.exe "C:\Program Data\BOINC\client_state.xml"
3. Search and replace the <max_nbytes>128000000.000000</max_nbytes> value to <max_nbytes>198000000.000000</max_nbytes>
4. Save and Exit
5. Restat BOINC manager.

@ritterm - It should be ok. It's the "sent time" that counts for this issue.

You can anyway check the <max_nbytes> parameter, as above, to be sure.

Thanks, Toni. I checked the client_state file and there appear to be numerous files with different <max_nbytes> settings for the WU. Again, just so I'm sure I've got this right, the output file is the one ending in "_4"? If so, I think I'm okay:

I have never seen that number that high, and since in the last few days, I have been getting nothing but these Noelia units, putting 2 and 2 together, I ask that question again, what's the big thing that we are crunching here?

One of my cards need only 13 hours to compute, but the 3g connection has uploadspeedproblems and i need over 14 hours to upload. So it blocks new wus to download and i miss the 24h bonus too :( so the card witch needs over 18 hours get the full bonus due high speed internet, what a Shame ^^

The Cuda31 versions of these tasks are very slow 24h+ on slightly factory overclocked 560ti all of the 4.2 tasks are working much better at most they take 16 hours(Always at-least 25% faster sometimes upto 40% faster). Unfortunately the server is passing out about 25% Cuda31 tasks to 42 capable machines and I always catch them to late to make aborting worthwile.

Maybe they would consider extending the 24hr bonus time to 36hrs or even 48hrs for these longer WUs. A lot of people seem to be struggling to finish them in 24hrs.

Sounds like a reasonable request given that the tasks are so long (~17h on a GTX470) and the Work Units are only two steps deep. However, all 20,000WU's should be completed by early January, so it's a short experiment, and it would be a lot of work to redo the credit system for a single batch of tasks - something the researchers would not want to be doing for every new batch!
Anyway, this 2task-deep research model is a test, and might not be adopted.

See Gianni's recent New Year experiment post.

What do they mean by "2-step deep" ?

In this project every workunit we process is a piece of a "longer" Molecular Dynamics simulation. So when a workunit is finished, uploaded and validated, then its result will be sent to another host to process the MD simulation from where the previous one has finished, until the whole given timeframe of the MD simulation is completed. For example: the whole timeframe for the MD simulation is 1µsec, it will be divided into 100 pieces of 10ns workunits (aka "steps"). However in the case of NOELIA_hfXA_long, there are only 2 such pieces.
On the server status page there are 22.000 unsent long workunits right now, in this case every one of them will be processed twice, while in other cases there are only 2.200 unsent long workunits, but those usually processed for 100 times.

How about this for a down-to-the-wire full bonus WU:



And this after a 2hr:40min upload!

It does seem a bit daft that upload time should be added to processing time. Doesn't a done WU package include processing-end time??

Credit is applied when a task is reported, it's not based on runtime. While you obviously have a point, report time is the time it tasks to download, run, upload and report a task.
Tasks aren't of any research use until they are uploaded. Reporting is different; it's a separate tiny upload, mainly for credits, and goes to a different database.

Good to see you managed to get that task reported in time. I suggest people lower their cache (where possible) if you are close to missing out on a time bonus.

Now that we have these units uploading successfully, I noticed that the server status has 22,000 + work units listed as unsent. I have never seen that number that high, and since in the last few days, I have been getting nothing but these Noelia units, putting 2 and 2 together, I ask that question again, what's the big thing that we are crunching here?

I've been able to get nothing but the Noelia WUs either. They take too long to run to meet the 24hr deadline so have moved the NVidias to other projects. The Toni WUs are the only ones that work OK on my 4 cards as the Nathans take too much memory to run efficiently. Will check back from time to time as I would really like to be running GPUGrid...

Message 27852 - Posted: 27 Dec 2012 | 18:13:28 UTC - in response to Message 27847.

What do they mean by "2-step deep" ?

In this project every workunit we process is a piece of a "longer" Molecular Dynamics simulation. So when a workunit is finished, uploaded and validated, then its result will be sent to another host to process the MD simulation from where the previous one has finished, until the whole given timeframe of the MD simulation is completed. For example: the whole timeframe for the MD simulation is 1µsec, it will be divided into 100 pieces of 10ns workunits (aka "steps"). However in the case of NOELIA_hfXA_long, there are only 2 such pieces.
On the server status page there are 22.000 unsent long workunits right now, in this case every one of them will be processed twice, while in other cases there are only 2.200 unsent long workunits, but those usually processed for 100 times.


Would this explain the size of these WU? (2 step deep means longer timeframe of simulation per WU, right?)

Why don't you switch to the short task queue? AFAIK they still get a 24 hour bonus and are at least 1/2 the length or less of the long tasks.

1) Go to your account area
2) Under "Preferences", select "GPUGRID Preferences"
3) Select "Edit GPUGRID preferences" for setting appropriate for your host (default, home, school, work)
4) Under "Run only the selected applications", check "ACEMD standard" and be sure the others are not checked.

Hope that helps!

Tomba, you are viewing your account information that everyone can see.

To view your preferences however, click on your name on the top right of the GPUGRID web site. It should be next to server status, and is above the Volunteers and the Science links. This will take you to the correct account area where you can change your preferences.

Look at the top of the picture you posted, and click on tomba.

Just had another Noelia "Error while computing", after eight hours of crunching. That's the sixth out of a total of 15.

Can I please have more Nathan benHPs...?

Are you overclocking your card? Is your computer crashing? Things like that can cause these errors.

Obviously you can't have more of them.
Your error is an "Energies have become nan", so see the appropriate thread.

Is there any way to stop the old 31 wus from hitting my machine other than checking and aborting manually? These are insanely slow on my old 560ti. The server reports 1000s of wus ready to send and when I abort a 31 wu it almost always send a 42 task so I'm thinking the server isn't out of 42 wus. I saw this rarely in the past with the long queue but it seems much worse with these tasks.

You can try my workaround on Linux:
1. turn off file size checking in cc_config.xml
2. overwrite the cuda31 binary with the cuda42 binary

We can remove already 3.1 apps on the long queue, but we will not upgrade the application until new year.

Your error is an "Energies have become nan", so see the appropriate thread.

Thank you for responding. I went there. All a bit confusing BUT I think I got the message that I need to under-clock my GPU. In just over two months I've had 16 "errors" out of 94 "good" WUs (yes - I log all my WUs...)

I have an ASUS GTX 460 1 gig. Stock settings are Core: 675, Shader: 1350, Mem: 1800.

For the 18 months I've had the 460, I've been GPUGRID-ing at: Core: 850, Shader: 1700, Mem 2000. It's only recently the errors have reared their ugly heads...

I have 'EVGA Precision', that lets me do changes, though I have nothing that lets me change the voltage...

Can I please ask you to recommend which of the three parameters I should change to give me the best chance of avoiding errors.

Many thanks, Tom

I have an ASUS GTX 460 1 gig. Stock settings are Core: 675, Shader: 1350, Mem: 1800.

ASUS have their own GPU overclocking tool, but I don't recommend it.

For the 18 months I've had the 460, I've been GPUGRID-ing at: Core: 850, Shader: 1700, Mem 2000. It's only recently the errors have reared their ugly heads...

As the GPU is getting older, it can tolerate less overclocking.
Also, the CUDA4.2 tasks tolerate less overclocking than the old CUDA3.1 tasks.

I have 'EVGA Precision', that lets me do changes, though I have nothing that lets me change the voltage...

I use and recommend MSI Afterburner for that purpose.

Can I please ask you to recommend which of the three parameters I should change to give me the best chance of avoiding errors.

1. Cleaning the cooling fins of the GPU and the CPU with high pressure air duster (using a vacuum-cleaner at the same time is recommended)
- (also the PSU, as much as you can do it through the rear grille, or the fan)
2. If there is any overclock applied to the PCIe bus, cancel it, and set the PCIe bus frequency to its default of 100MHz
3. GPU memory clock is irrelevant, raising it is just asking for trouble. (set it to factory default)
4. You can raise the GPU voltage by 0.025V increments as long as your GPU temp is below 80°C (and gets stable).
5. Lower your GPU core clock by 10MHz decrements, until it gets stable. (note that not every frequency can be set, so the actual GPU frequency can be ~3MHz lower than the value beside the slider)

Message 27878 - Posted: 29 Dec 2012 | 21:01:10 UTC - in response to Message 27876.

Firstly make sure the GPU Fan speed is keeping the GPU below 70°C. Sometimes adding a case fan or opening the side panel helps.
Start downclocking by reducing the GDDR5 frequency by 10%
If that fails try 20%.
If need be reduce the GPU clock by 5 or 10%
If these measures fail get software to increase the Voltage, but only by the least amount (typically ~0.025V)

Note that Rosetta tasks were causing issues a while back, and might still be; I think some tasks used up too much RAM, which causes memory caching to disk and numerous related errors.

Again, thank you for responding!

I use and recommend MSI Afterburner for that purpose.

I installed that...

1. Cleaning the cooling fins of the GPU and the CPU with high pressure air duster (using a vacuum-cleaner at the same time is recommended)
- (also the PSU, as much as you can do it through the rear grille, or the fan)

I do that religiously every three months. Just did it again. Fans are running quieter.

2. If there is any overclock applied to the PCIe bus, cancel it, and set the PCIe bus frequency to its default of 100MHz

I have no idea how to do that so I assume it's at default.

3. GPU memory clock is irrelevant, raising it is just asking for trouble. (set it to factory default)

Did that using Afterburner.

4. You can raise the GPU voltage by 0.025V increments as long as your GPU temp is below 80°C (and gets stable).
5. Lower your GPU core clock by 10MHz decrements, until it gets stable. (note that not every frequency can be set, so the actual GPU frequency can be ~3MHz lower than the value beside the slider)

4. and 5. I shall save for later. I now have a dust-free PC and and a default GPU memory clock. One step at a time...

Thanks again!

My GPU temp is a solid 65°C

Start downclocking by reducing the GDDR5 frequency by 10%

I get REALLY confused by the variations in terminology. What is GDDR5 frequency??? Is that core, shader, memory???

I guess so, but I'm not the person who has comprehensive knowledge about these workunits.

I think it means task generations; so 2 steps would mean completing a batch of tasks and then a second batch, auto-generated from the first batches results.
