I upgraded to 5.10.45 a little while ago.
Everything was going fine then about two days ago my computer suddenly stop processing two work units at once on my hyper threaded processor and went to only one work unit at a time. Any suggestions as to how I would get it to go back to processing two at a time? Also I cannot tell the estimated completion time on the work unit currently in process any more as my Boinc manager reads to completion time as 00:-8:-8 any ideas Attached below is message print out: 3/29/2008 9:51:27 AM||Starting BOINC client version 5.10.45 for windows_intelx86 3/29/2008 9:51:27 AM||log flags: task, file_xfer, sched_ops 3/29/2008 9:51:27 AM||Libraries: libcurl/7.18.0 OpenSSL/0.9.8e zlib/1.2.3 3/29/2008 9:51:27 AM||Data directory: C:\Program Files\BOINC 3/29/2008 9:51:27 AM||Processor: 2 GenuineIntel Intel(R) Pentium(R) 4 CPU 3.00GHz [x86 Family 15 Model 4 Stepping 1] 3/29/2008 9:51:27 AM||Processor features: fpu tsc sse sse2 mmx 3/29/2008 9:51:27 AM||OS: Microsoft Windows XP: Home Edition, Service Pack 2, (05.01.2600.00) 3/29/2008 9:51:27 AM||Memory: 2.00 GB physical, 3.85 GB virtual 3/29/2008 9:51:27 AM||Disk: 71.46 GB total, 51.24 GB free 3/29/2008 9:51:27 AM||Local time is UTC -4 hours 3/29/2008 9:51:27 AM|World Community Grid|URL: http://www.worldcommunitygrid.org/; Computer ID: 179076; location: (none); project prefs: default 3/29/2008 9:51:27 AM||General prefs: from World Community Grid (last modified 13-Jun-2007 06:33:39) 3/29/2008 9:51:27 AM||Host location: none 3/29/2008 9:51:27 AM||General prefs: using your defaults 3/29/2008 9:51:27 AM||Reading preferences override file 3/29/2008 9:51:27 AM||Preferences limit memory usage when active to 2045.93MB 3/29/2008 9:51:27 AM||Preferences limit memory usage when idle to 2045.93MB 3/29/2008 9:51:27 AM||Preferences limit disk usage to 18.63GB 3/29/2008 9:51:27 AM|World Community Grid|Restarting task lq308_00006_10 using hpf2 version 518 3/29/2008 12:11:08 PM|World Community Grid|Computation for task lq308_00006_10 finished 3/29/2008 12:11:08 PM|World Community Grid|Sending scheduler request: To fetch work.

Maybe 5.10.45 got smart. A P4Ht should ideally only process 1 at the time, so was the recommendation when i came aboard with a P4HT 2 years ago. In fact, if you are going to measure the wallclock time, you'll probably discover that the gain of 2 sequential versus 2 parallel is like very little. Your processor is also likely running hotter with 1 real and 1 virtual CPU processing BOINC in parallel.

Thank you for the reply Sekerob, I guess I will let it process one work unit at a time then.
Would you have any idea about my other question re the completion time displaying 00:-8:-8 |

Have you tried restarting BOINC?
Actually, I recommend you stop and exit BOINC, then delete client_state.xml and client_state_prev.xml, then restart BOINC. You may lose any work in progress, but I think this offers the best chance of fixing any problems you have. |

Thank you for your reply Didactylos, I will try your recommendation after the single work unit I have going is completed.

Hello Didactylos:
As you suggested I Stopped Boinc and deleted Client_state.exm and Client_state-prev.xml and restarted Boinc. Everything back to normal, completion time reads correctly and crunching two work units again. One question re Sekerob's reply should I ideally only be crunching 1 work unit at a time. I have been crunching 2 units at a time for about a year now and in all that time I have only had 2 work units with a problem. If the recommendation is to only crunch one at a time that's what I will do but I would appreciate any additional input before a change to only one, seems like a waste if I can do two at a time. |

An HT computer isn't doing two at a time, it's like doing 50% of one and 50% of another at the same time, with time taken rapidly swap between them. It's not really accomplishing much. There's only one floating point register to share.
----------------------------------------HT can be turned off/on in the BIOS. I can do sort of the same thing on a single core by running UD and BOINC at the same time. Each one gets half of the power, but takes twice as long, less the overhead. It doesn't save anything. On the other hand, the newer AMD X2, Amd Phenom, Intel Core Duo, 2 Core Duo are true dual and quad cores, running one workunit in each core.

Thanks for your reply retsof
One question if I turn HT off what are the advantages vs disadvantage of doing so? I assume HT was set up and made available for some reason. If I turn HT off how will it affect other things I may want to do on my computer? |

dseto, you dont need to switch off the HT function in the BIOS. Simply tell BOINC to only use 1 processor. You can set that in either the Website My Grid > Device Manager > Device Profile > Default > Custom Profile or in the local prefs entered thru the 5.10.45 Advanced Menu Preferences, Processor Tab.... it's near the bottom. This way all your HT features, if used by any other application remain intact.

Thanks for the reply Sekerob I will do that.
I just compared my completion times when I was only doing one unit at a time and they seem to complete faster. Also from retsof's reply as I am only swaping back and forth between two work units sharing a single floating point register it does seem like only doing one unit at a time is the way to go. I would make this thread as complete but I am not sure how to do that, could you please do that for me. |
