22) Message boards : Number crunching : R9 290X (Message 61039) Posted 10 Feb 2014 by Jesse Viviano Post: That depends on your R9 290X. Is it a full-custom card or a reference card with a custom cooler? If so, look for a project that needs lots of integer performance. The cryptocurrency craze shows that this GPU is the integer king. AMD was intending to have high integer performance to speed up video encoding which requires lots of integer performance and some floating point performance, but hit the cryptocurrency market instead. Is it a reference card with a reference cooler? Either forget about BOINC on this card and replace this card before it burns itself out or water cool the card. The inadequate cooler on this card will run the card at 95 degrees Celsius and throttle the card's performance when that threshold is tripped. AMD stated that this card was designed for high temperatures, but I don't believe it, much as my disbelief at Nvidia's claim that the GTX 480 was designed for high temperatures was validated when GTX 480s started failing according to what I remember reading in forums. If you want to keep the card, water cool it. In all cases, monitor the GPU and the VRM temperatures. Some custom cards have been shown to cool the VRM adequately only when the fans are allowed to run at performance/uber mode but let the VRM overheat in quiet mode.
23) Message boards : News : Some new work units running (Message 61037) Posted 10 Feb 2014 by Jesse Viviano Post: I do not think that anybody can get any of them. When I try to update MilkyWay@home in BOINC, I get a feeder not running error.
24) Questions and Answers : Windows : OpenCL tasks on Haswell? (Message 60792) Posted 22 Jan 2014 by Jesse Viviano Post: No. OpenCL below version 2.0 requires that either the developer compile for each GPU vendor's architectures using the GPU vendor's OpenCL library or ship source code that would be used by the platform's compiler. The second approach would be ideal if all operating systems came with a compiler, but most Windows installations do not have any compilers installed. Therefore, you would need the developers to compile using Intel's OpenCL library before you can use your GPU for MilkyWay@home.
25) Message boards : MilkyWay@home Science : Has the science page of this website been hacked and vandalized? (Repost from website Q&A forum) (Message 60791) Posted 22 Jan 2014 by Jesse Viviano Post: In the Milkyway@home science page, the statement "Recently, it was determined that the bulge contains a prominent bar." looks like Wikipedia-style vandalism because it implies that there is a place to get some food and alcoholic drinks in the Milky Way's bulge. Could an administrator look into the issue and plug any security holes to carry out this vandalism if they are discovered, or is there some meaning to the word "bar" that I do not understand? This is a repost from the website question and answers forum at http://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=3454, because I am not sure that anyone is paying attention to that forum as the last post in there was around 4-5 years ago until I made my original post there. Please post replies there as that is the proper forum for this topic.

27) Message boards : Number crunching : Having downloaded wus in jobs list that are not listed and running in client? (Message 51946) Posted 13 Dec 2011 by Jesse Viviano Post: I have had this problem. What you need to do is to select No new work for MW@Home, let all of your work units that you have on your computer finish, update the project to report the finished work units, and then reset the project. This will let the server know that the other work units failed. They will be listed as "Abandoned", and hopefully will be passed to someone who was able to download the N-Body application. I don't know why BOINC is failing to report download errors for these bad work units because the executable for N-Body version 0.80 for 64-bit Windows apparently cannot be downloaded. It is just silently discarding those work units instead of reporting errors to the server.
28) Message boards : Number crunching : Error message from n-body (Message 51913) Posted 11 Dec 2011 by Jesse Viviano Post: I am getting the same problems here. I will have to detach until this is fixed to prevent pollution of the MilkyWay database with any more bad work units. We all know how problematic the database is, and I do not want to add to its troubles by filling it up with invalid work. I have tried resetting the project and a manual detach and reattach.

30) Message boards : News : more maximum time limit elapsed bug stuff (Message 48882) Posted 20 May 2011 by Jesse Viviano Post: Could it be possible that your settings are not accounting for the possibility that when BOINC responds that there are 12 processors to use that it is failing to account for the hyperthreading my 6-core hyperthreaded processor is presenting? BOINC might be expecting twice the processing power it is actually getting. I noticed that some of the work units that fail on a Core i7 with hyperthreading work well on a Core 2 without hyperthreading.
31) Message boards : News : more maximum time limit elapsed bug stuff (Message 48872) Posted 19 May 2011 by Jesse Viviano Post: I recently upgraded my BOINC client, and I am still getting some n-body work units that fail due to maximum time limits exceeded. Some n-body work units also pass. Few if any of the regular work units are giving me problems, and the last problem regular work unit I had was with the ATI client failing to record the results to stderr, and that was a week or two ago and has nothing to do with this problem. I wonder if you might get some help if you visit http://boinc.berkeley.edu/dev/ and use the message boards there or the BOINC projects email lists at http://lists.ssl.berkeley.edu/mailman/listinfo/boinc_projects for help. There might be a setting that you might be overlooking that could be obvious to another person. The same problem happens to the best of us (e.g. someone failing to declare a variable as volatile in C when using it to spin-wait on an I/O transaction and therefore the compiler optimizes the variable by moving it to a register).
32) Message boards : News : more maximum time limit elapsed bug stuff (Message 48862) Posted 19 May 2011 by Jesse Viviano Post: I am still getting maximum time exceeded errors on the n-body work units, though one or a few are now completing successfully. My computer is now going into high priority mode as well. One failed at 82%. Another failed at 85%. It looks like I am getting a mix of successes and failures. These failures were under BOINC x64 version 6.10.60. Since BOINC released a new version, 6.12.26, I have upgraded since then.
33) Message boards : News : another change for the maximum time limit elapsed bug (Message 48661) Posted 9 May 2011 by Jesse Viviano Post: You might need to double the deadline. I just got a computation error on an N-body work unit after getting around 63% of the work unit done. I am using a Core i7 980X with hyper-threading enabled. Nothing is overclocked.
34) Message boards : News : maximum time limit elapsed bug (Message 48621) Posted 9 May 2011 by Jesse Viviano Post: The n-body WUs are failing due to maximum time limit elapsed. Everything else is fine. I have Win7 64-bit, an Intel Core i7 980X, and a Sapphire Radeon HD 6970. I am using BOINC 6.10.60. My Catalyst drivers are the 11.4 production drivers. I am using stock everything, no app_info.xml, and no overclocking whatsoever.
35) Message boards : News : fix to the invalid workunit problem (Message 48529) Posted 7 May 2011 by Jesse Viviano Post: I noticed that many of the work units now only allow a maximum of one error before the work unit is rejected. That seems to be a bad idea due to the number of people with outdated graphics drivers (causing some ATI/AMD work units to fail) and those with optimized applications that will generate validate errors because they still upload results with file uploads, where the validator no longer looks.
36) Message boards : News : n-body workunits with maximum time elapsed (Message 48522) Posted 7 May 2011 by Jesse Viviano Post: It seems that all the results I am turning in are now being marked invalid for the main MilkyWay@home application.
37) Message boards : News : N-body updated to 0.40 (Message 48510) Posted 6 May 2011 by Jesse Viviano Post: I am getting a maximum time exceeded error on my N-body work units after running for 3 seconds. I will try resetting the project to see if that will help. Some have suggested that using an app_info.xml is causing this, but I have not ever worked with any app_info.xml file. Oops! I accidentally forgot to do the reset when I allowed more tasks in.
