2) Message boards : Number crunching : All ps_separation tasks are getting computation errors (Message 60739) Posted 14 Jan 2014 by Michael Purcell Post: I updated my MW profile to select these applications (and avoid the work units getting computation errors). MilkyWay@Home: yes MilkyWay@Home N-Body Simulation: yes Milkyway@Home Separation: no Milkyway@Home Separation (Modified Fit): yes I am receiving ps_separation, de_modfit and ps_modfit work units. How do I stop the ps_separation work units from getting sent to me?
3) Message boards : Number crunching : All ps_separation tasks are getting computation errors (Message 60737) Posted 13 Jan 2014 by Michael Purcell Post: No. I updated the gpu drivers about a month before starting Test4Theory. VirtualBox was already installed but was unused by MW or Cosmology@Home. I will go ahead and refresh/update my drivers to see if that improves anything.

I have updated the MW project preferences. Something odd now. The Transfers queue has a number of downloads pending (with "project backoff"). Retries fail. They seem to be for MW exe's, dll's, and other data (stars-16, stars-17, etc.). Perhaps I should remove the MW project, wait a day, and then add MW back in.
5) Message boards : Number crunching : All ps_separation tasks are getting computation errors (Message 60733) Posted 13 Jan 2014 by Michael Purcell Post: I agree. This is not the fault of BOINC. VirtualBox (or Test4Theory) corrupted something on my system. My hope had been that a clean uninstall of everything and a reinstall of BOINC and MilkyWay would fix the problem. No such luck. I can probably avoid the error by removing the use of the GPU. The work units will take 10x longer but at least the ps_separation work units will run. The other choice is to leave things as they are with the ps_separation computation errors and ps_modfit success. Do you have a preference?
6) Message boards : Number crunching : All ps_separation tasks are getting computation errors (Message 60731) Posted 13 Jan 2014 by Michael Purcell Post: Thanks for the info. v7.2.37 would not do transfers or downloads. I removed it and reinstalled v7.2.33. Prior to the above I had tried to thoroughly remove all traces of BOINC as described at http://tinyurl.com/mx3bpad . I had also removed all my BOINC projects prior to uninstalling (after letting them complete their in-progress work units). The computation errors on the ps_separation GPU work units are still occurring. The ps_modfit GPU workunits complete just fine. The BOINC log only shows that the ps_separation work units finished. The log does not contain any error codes or diagnostics. Any suggestions what I can look into to get more info on the error? I truly regret ever touching VirtualBox or Test4Theory. Thanks.
7) Message boards : Number crunching : All ps_separation tasks are getting computation errors (Message 60723) Posted 11 Jan 2014 by Michael Purcell Post: I originally installed BOINC 7.2.33 and VB 4.2.16 x64 together from https://boinc.berkeley.edu/download.php (v7.2.37 is not yet posted.) I did nothing special during the installation, and did not try to make it a service. I just now reinstalled them and let MW get new tasks. The ps-separation problem is recurring. What I will try next is to remove Test4Theory, uninstall VB, then reinstall BOINC using the installer that does not include VB to see if I can get a clean setup that works for MW. Do I need to do a full uninstall of BOINC first as well, or can I use the "repair" option? Thanks.
8) Message boards : Number crunching : All ps_separation tasks are getting computation errors (Message 60716) Posted 11 Jan 2014 by Michael Purcell Post: I have been running MW just fine for years on Windows 7 x64 (AMD HD 5870, latest drivers). With the latest BOINC update (7.2.33) I also installed VirtualBox. Things were good. I started running Test4Theory, which uses VB. Test4Theory and the ps_separation immediately started getting computation errors (modfit tasks continued to run successfully). I learned that the current VB has problems so I removed it and installed v4.2.16 which was supposed to be good. The errors continued. I set Test4Theory to NoNewTasks and uninstalled VB. I also went through my directories deleting residual .VirtualBox references. ps_separation work units are still failing with computation errors. The modfit tasks are fine. (I also run Cosmology@Home. It was not affected.) Any suggestions? Thanks.
