	Damn, now the vlars are broke again? Not that i've noticed. There aren't a lot about at the moment, but since the outage all that i have received have gone to my CPUs, not my Nvidia GPUs. ____________ Grant Darwin NT.

	Good! A check of the server logs also shows that the VLAR prevention mechanism should be in place. ____________

	I don't know how to write code and was hoping someone might post a cc.config.xml that forces BOINC to use my single GTX 550 Ti gpu..can't seem to get any task to utilize this gpu...please help. Thank you in advance. I am using version 7.0.28

	Hello ?! what bug in nvidia is it exactly ? nvidia in Window$ or nvidia under Linux ? It seems that driver-package of nvidia has those bugs, who are creating trouble under Linux - wherefor it is better to run vesa under Linux than nvidia-drivers ... sometimes it is better not to use the most modern or most actual software like those drivers of nvidia, which are not completely un-bugged. Regards. samspade.

	... cc.config.xml that forces BOINC to use my single GTX 550 Ti ... You don't need cc_config.xml to use GTX 550 Ti for BOINC purposes, you need CUDA driver. So, never let Windows to install/update video card drivers! (they lack many features) Get the driver from the video card manufacturer or the GPU manufacturer (in your case NVIDIA) Check with GPU-Z to see if CUDA and OpenCL are installed. ____________ - ALF - "Find out what you don't do well ..... then don't do it!" :)

	what bug in nvidia is it exactly ? There are bugs in nVidia drivers (as in any other software) but this thread is not about any of them. The bug was in the server part of BOINC (at setiathome.berkeley.edu) (Not connected/induced by anything that you as user do or not do on your machine (except your chosen BOINC version). The problem: the new BOINC server code (that runs in the SETI lab at Berkeley) 'forgot' that it have to connect also to older (before v7) BOINC versions on the user machines. The new BOINC server code reported <type>NVIDIA</type> but the older BOINC versions on the user machines understand only <type>CUDA</type> Now BOINC server code is fixed to report <type>NVIDIA</type> if you use BOINC 7.0 (or later) and <type>CUDA</type> if you use BOINC < v7 (e.g. 6.10.x) ) ____________ - ALF - "Find out what you don't do well ..... then don't do it!" :)

	My GTX560 TI and 2x GTX550Ti rigs don't seem to have a problem with them other than they take 3-5 times longer to complete than an average work unit (both rigs no signs of bogging down even with each card doing 2 at a time). It will interesting to see how my 3x 9800GT rig handles them when it comes to getting into its lot, but then drivers have come quite a long way since the VLAR code was first introduced. Cheers. ____________

	This thread is not about 'VLARs on NVIDIA GPUs' It's about different problem: running many (e.g. 10-40) tasks (of any AR, not only VLAR) on single NVIDIA GPU (I'm not sure if this problem affects 'Anonymous platform' hosts) ____________ - ALF - "Find out what you don't do well ..... then don't do it!" :)

No, the problem only happened to hosts running stock where the server sends a complete app_version. Hosts running anonymous platform are merely told which of the app_versions listed in the app_info.xml to use. Joe

	2) the "Server Status" page shows as a blank! (as of time & date posted) It's partially available on http://setiathome.berkeley.edu/server_status.php although very slow to load to it. Thus looks like a new server setup has been loaded, as the 'server_status.php' page is the default page in the BOINC back-end source code. 'sah_status.html' is the Setified page for it, but not the standard one. ____________ Jord - BOINC FAQ Service - BOINC User Wiki Real is just a matter of perception.

	I just put up a new machine, Enigma III. I can't get work. All my machines will be changing over the next two weeks. I never have been successful in bringing work assignments to a new machine. ( a little help? ). When might I see work for Enigma III? ____________

	When might I see work for Enigma III? Shouild be soon. The project has had problems and work's underway. Downloads just came back. If you don't get some soon, open a thread in Q&A or Number Crunching - we don't usually do troubleshooting in this forum. ____________ Another Fred Support SETI@home when you search the Web with GoodSearch or shop online with GoodShop.
