In my case almost every work unit failed (a few, say, ~10% finish successfully). This is a on a Yorkfield core (Intel Core Quad Q9300). Note: The optimized MB SSE3 and SSE2 (editor: other applications) suffer the same fate as optimized astropulse on my system. Editor: the similarities are (1) all applications are build with intel compiler and (2) all applications tend to heavily stress CPUs. Other possibly relevant information: einst...@home is the only other project running on this machine VMware Server 2.0.1 is used to run a Windows XP guest This was rock solid under Ubuntu 8.10 (i.e. never experienced a single work unit error). I tried both BOINC 6.2.15 and 6.6.20 to see if it made any difference, but it did not. -- Seti application expieriences SSE3 emulation crashes on Jaunty Jackalope 9.04 https://bugs.launchpad.net/bugs/371337 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
