I would like to ask for advice.

My new GPU card (http://www.primegrid.com/forum_thread.php?id=2677) from time to time completes WU with error.
I wonder if it is possible to do something about it. I have checked error code is always the same:

Cuda error: getting factors found: unspecified launch failure

So far the card has completed 126 WU: 104 WU successfully, 22 WU were discarded as error (which is about 20%).
Card is running with default settings, card is not overclocked.
As for run time I see no pattern here, some WU ended after 20sec other almost completed about 2100sec.
Card drivers were downloaded from nvidia webpage: NVIDIA-Linux-x86_64-256.53.run

BOINC detects card as:

What is the reason for "getting factors found: unspecified launch failure" error message?
Should I suspect hardware or software problem?

Cuda error: getting factors found: unspecified launch failure

4GB hard drive? Is this a virtual machine?

If so, I suspect that may be the problem. As far as I was aware, you couldn't run CUDA apps in a VM.

You might want to try running CUDA on the host machine rather than in the VM. Since your computers are hidden, it makes it a little hard to diagnose the problem from afar.

This is not a virtual machine.

I wanted to install Dotsch/UX linux distribution at pendrive, but I have found this drive in my garage and decided to try it.
It has worked as you see...and now it is my "vintage" pendrive :-)

The hard drive is: MPC3043A 4.3GB U/ATA FUJITSU HARD DRIVE

Other PC components are: E5200 @ 2.50GHz running Gigabyte GA-P43-ES3G with 2GB RAM, powered by 400W power supply.

I have checked syslog/messages logs for any suspicious information, but found nothing.
Besides this PC is also crunching other BOINC projects for CPU like WEP-M+2 and WCG.
No problems with WU for those projects...so if that would be hardware issue (memory failure or CPU overheating) those projects should be affected too.

It looks like "unspecified launch failure" is the equivalent of "segmentation fault", which I've been getting in the OpenCL testing. These errors are caused most often by a bug in the code, but could also be caused by hardware failure. On the other hand, since I haven't heard about many CUDA users having problems, I'm not sure what to think.

Have you tried Collatz yet on that card? It's another simple math app that would provide a good test of the hardware.

It would also be helpful if people who asked for help with their computers didn't hide their computers, or at least posted links to example results.

Computers at my account are now visible, the one having problem is hostid=157777.

Is there any other way to test the card, besides running Collatz?
Some other application under Windows? I mean I have nothing against it, just asking for other possibilities.

I could also move the card to another host, for example hostid=147474.

The fact that most of the WUs are passing makes me think hardware. I'm sure there are better GPU testing programs; I'm just not sure what they are.

I am not saying it is not a hardware, but after reviewing results it looks like I am not the only one having problem. I have checked what were the results for my task run by other computers to reach quorum. Below are few examples, outcome of three attempts plus additionally at round brackets GPU details.

I see frequently message about insufficient memory available, also at the other task I have not pasted above. What is the minimal amount of memory required to run the PPS CUDA? Does it change by WU, or this value could grow and exceed initial value during calculation? Maybe my cards has the same problem, but due to drivers reports it with other message?

As for my case I will move today the card to another host running Windows to exclude drivers and operating system impact.

You're not the only one getting errors, but I'm not seeing anyone else getting your specific error.

Short lesson on known error codes:

Detected emulator! We can't use that! ( NVIDIA GeForce GTX 260 (895MB))

For some reason, when a CUDA API older than 3.1 is installed, BOINC thinks the emulator it installs is a real GPU! Well, it's not, and we can't use it. The app could be compiled to use it, but the emulator runs about 1/30 as fast as the CPU code. So just failing the WU seems like the best option.

WU=129819591
...
Insufficient available memory on GPU 0. (NVIDIA GeForce 9600 GT (499MB) driver: 25896)

This is usually the exact same error as the last one, just interpreted differently. v1.28 specifically calls out the emulator attempt, but it's only running on Linux right now. v1.27 reports this generic error code, after reporting "Detected compute capability: 9999.9999". When it's running on a real card, this error means something else used up the video RAM.

WU=129816514
...
CreateProcess() failed - (NVIDIA GeForce GTS 250 (512MB) driver: 19107)
CreateProcess() failed - (0x36b1) >>without cuda23<<

It looks like, in the first case, someone needs to reinstall the Microsoft VCredist 2005 C++ redistributable package. I found BioShock failing with the same error. I don't know what caused the other failure, but I'm pretty sure it wasn't my code.

Cuda error: getting device properties: CUDA driver version is insufficient for CUDA runtime version
Self-explanatory.

Cuda error: cudaEventCreate: out of memory (NVIDIA GeForce 9500 GT (511MB) driver: 19062)

OK, this one's a mystery. I suspect it's a case that some other process ate up all the video RAM while the program was running, but I'm not entirely sure.

Let me know if you find anyone else reporting your specific error. Especially if a single WU has multiple people reporting that error.

Thank you very much for explanation for error codes! I may also help somebody in the future.
I will keep monitoring my card and continue to search other people reporting "Cuda error: getting factors found: unspecified launch failure" error.

P.S. So far 108 out of 142 WU completed with success, which sets completion rate at 76%...:-(

This one is the driver. On multiple GPU's I had the same with all 190.xx and 191.xx drivers. 195.xx and above solve the problems...if I recall correctly, some new memory stuff was introduced in the 195.xx driver series that slowed down some cards (on Collatz and with the AP26 app here) and also resulted in the larger memory report problems (i.e., 191.xx drivers reported 255mb out of 256mb on some cards/OS'es whereas 195.xx reported even less...typically 243mb).

After moving GT240 card from hostID:157777 (Ubuntu x64) to hostID:147474 (Windows XP x86) I was able to successfully complete 46 out of 48 tasks. This is 95% comparing to 75% at previous computer. Moreover at new host I have increased shrader speed from 1460MHz to 1650MHz, while meantime lowering memory speed from 4000MHz to 3400MHz. Those two invalid WU were generated with even higher shader speed, so I think that could be the issues. After those I lowered the speed to stable 1650MHz and all WU passed since that time.

I will keep it there running until I complete 100WU to have reasonable representative sample.
So far it does not look like faulty GPU, but to diagnose the root cause there is a still long way to go....

Did it work before you lowered the memory speed?

Yes, it did. At factory settings I finished about 4 WU, then decided to increase shrader speed and did another few. Then I crossed 1700MHz range and failed, but not two times in a row. I moved back to 1650MHz and did another 10 or so and finally decided to lower memory speed (since it should not affect the performance) to keep temperature down. Temperature dropped from 64 to 63 Celsius, so not much really...

Is there any possibility to independently change speed of core, shrader and memory under Linux? I would like to move card back to old host, keeping the same settings as under Windows. Zotec does not provide similar software for Linux and Windows. I checked Nvidia X Server after activating Coolbits, only GPU and memory speed could be changed. I also checked nvclock and it does not support GT 240.
