1) Questions and Answers : Unix/Linux : Astropulse errors ... (Message 1138790) Posted 11 Aug 2011 by Stephan Goll Post: Well, I've seen http://setiathome.berkeley.edu/forum_thread.php?id=63564 .The sad thing is, that my crunchers show the same problem ... but the "funny" thing is that there is no screensaver. Not even a trace of ... because my crunchers are running headless. It is about http://setiathome.berkeley.edu/hosts_user.php?userid=32167. Astropulse normally errors out in the first second, but on the atom with CUDA it sometimes crunches a long time until the workunit will finish. Memory and cooling is fine, both boxes are crunching on einstein@home too and the SETI@home Enhanced v5.28 workunits are fine too. http://setiathome.berkeley.edu/workunit.php?wuid=795057091 took a very long time but ended successfully. My idea is that there may be something wrong in the application (or boinc code?) ... because: <core_client_version>6.10.58</core_client_version> <![CDATA[ <message> process exited with code 193 (0xc1, -63) </message> <stderr_txt> In ap_gfx_main.cpp: in ap_graphics_init(): Starting client. SIGSEGV: segmentation violation Stack trace (9 frames): [0x440158] [0x7f6484be6f60] [0x5959e1] [0x59130e] [0x59c266] [0x599ef6] [0x43d197] [0x7f6484bde8ba] [0x7f648494602d] Exiting... </stderr_txt> ]]> and <core_client_version>6.10.58</core_client_version> <![CDATA[ <message> process got signal 11 </message> <stderr_txt> In ap_gfx_main.cpp: in ap_graphics_init(): Starting client. </stderr_txt> ]]> Again: there is no X running on these crunchers ... and no screensaver because they are running headless. Is there a way to disable the function call to ap_graphics_init() or make it more tolerant? For me this looks like the main cause of the problem. Stephan
