      That is not the error, that is the result of the error. Because there was an error the result files are absent. You have to look at the stderr output for the actual error. That can be found here on the web site on your account page where your tasks are listed.

        Hi!

        It is because of "OpenCL Device used for Search/Recalc and/or semi coherent step: 'GeForce GTX 1050 (Platform: NVIDIA CUDA, global memory: 2048 MiB)". All those tasks that failed had so called DF of 0.50 . They required more memory than what your 2GB GPU is able to provide. Some GW GPU tasks with lower DF could run with a 2GB card, but a user isn't able to choose what kind of tasks the project server will send, considering the DF.

        It would be a fail safe solution to run only "Gamma-ray pulsar binary search #1 on GPUs" with a 2GB card.

          Hello Harri,

          Last 2 weeks I'm also facing the same problem mentioned in this ticket.

          Many WU's were cancelled after +/- 2 min CPU time. Based on your comment I had a look to the stderr output, but there're a lot of errors being mentioned (like unknown with exit code 1024) that I've no clue what they mean or how to correct this. An insider / developer will understand for sure, but I'm not.

          This is the stderr of one of the failing WU's, can you please have a look?

            Hi Paul !

            Your computer has "NVIDIA GeForce GTX 950M (2048MB) driver: 388.00".

            All the GW GPU tasks that failed had a DF of 0.50 (task ID's had xxxx.30 ... xxx.80 or xxxx.35 ... xxx..85 in their names, 85 - 35 or 80 - 30 = DF of 0.50). Those GW GPU tasks with high DF value will require more than 2GB of GPU memory. That's why they have crashed early in the beginning.

            Some GW GPU tasks with lower DF could run with a 2GB card, but a user isn't able to choose what kind of GW GPU tasks the project server will send, considering the DF.

            Currently it would be a fail safe solution to run only "Gamma-ray pulsar binary search #1 on GPUs" with a 2GB GPU.

            Also, the Nvidia GPU driver 388.00 on your computer is a three years old version. That could be a major problem for any kind of succesfull crunching with Nvidia GPU. I would definitely suggest you to visit Nvidia driver site and upgrade that driver to the latest version even if you didn't run Boinc.

              Hello Richie,

              Thanks for your quick feedback !

              Looking to my Speccy output I can see that my Nvidia GeForce GTX 950 M driver is current'ly '23.21.13.8800'. I wonder where and how you've see '388.00' (maybe your 388 is a sub string within 23.21.13.8800'?

              Finding a driver update at the Nvidia side is not easy (can't find the 950 M at all), but I'll continue anyway.

              Second question: how and where can I set I prefer to process 'Gamma-ray pulsar binary search #1 on GPUs' WU's as you suggest?

                    None of the people likely to reply here are "insiders" - we're all just volunteers like yourself.

                    The trick is not to look at error codes but to look (earlier in the output) for keywords.  In your case, the key information is contained in the line that says:

                    Processing FFT failed: CL_MEM_OBJECT_ALLOCATION_FAILURE

                    The app uses a process referred to as a "Fast Fourier Transform" (FFT) to process a very large number of data points, all of which requires a lot of memory.  The problem is that your GPU doesn't have enough memory to store the data - a memory allocation failure.

                    At earlier stages for this particular search, memory requirements were less so perhaps your card may just have had enough memory earlier on.  As the run progresses, memory requirements are likely to increase even further so even if some tasks are not failing now, the situation is likely to get worse with time.  As a general comment for anyone with a 2GB card, you should avoid the GW search and select the gamma-ray pulsar search instead.  2GB will be fine there.

                    Cheers,
                    Gary.

                      I wonder where and how you've see '388.00'

                      From the line "Coprosessors:" at the information page of your host... https://einsteinathome.org/host/12535157

                      That's what Boinc currently knows about it.

                      Yes, that sub string would tell the version also.

                      Finding a driver update at the Nvidia side is not easy (can't find the 950 M at all), but I'll continue anyway.

                      San-Fernando-Valley shot with precision already. Well, here would be just an alternative page to start searching for Nvidia drivers if in a need some day: https://www.nvidia.com/Download/Find.aspx?lang=en-us

                      Product Type: GeForce , Product Series: GeForce 900M Series (Notebook) , Product: GeForce GTX 950M , Operating System: Windows 10 64-bit

                      I'm not sure if that very old driver was yet of type 'DCH' but you could try an installation with that type at first.

                      Alternatively, you could first download and install GPU-Z . It would show "DCH" included at the "Driver Version" information if the currently installed driver is a DCH version. If it doesn't show "DCH" then you should choose the 'Standard' version.
