2) Message boards : Number crunching : Arm compute nodes ready to join (Message 4327) Posted 25 May 2020 by vpf3 Post: I didn't come up with this, but I remebered that it was posted some time ago: To get work with aarch64 you need in /etc/boinc-client/cc_config.xml a alternate platform string. <options> <alt_platform><span class="mark">arm-unknown-linux-gnueabihf</span></alt_platform> </options> Hope that helps, vpf
3) Message boards : Number crunching : Upload fails (Message 4293) Posted 11 May 2020 by vpf3 Post: Hello Keith, since U@H is CPU only, the CPU and the OS are the two biggest factors. Currently Linux systems are about factor 2 faster than Windows. I tested this on my own and it is software dependent. But since you use Ubuntu Bionic and Focal, there should be only marginal differences. Technically your Ryzen 9 3950x (same I have) is a beast on its own. By cores it should be 133%, by frequency 155% compared to your TR 2920x. But ZEN2+, specially on the 3950x with - the PBO (better heat control via more temp read areas), - the better Mainboard upscaling with power supply and - no cap on memory speeds (main limiting factor on all 1xxx and 2xxx AMDs) leads to 265% performance in your case. This is more than I expected, but maybe there is some deviation with tasks too. This sounds amazing but I recognized the same with my change from Ryzen 7 1800x (fastest CPU when I bought it) to Ryzen 9 3950x (got my hands on the very first ones). The tech scene was amazed about the real life performance of the Ryzen 9 flag ship. When compared to TR even (e.g. Linus Tech Tips) came to the conclusion that the Ryzen 9 somehow killed all TR 1xxx/2xxx line up completly. Hope than explains the part that xii5ku couldn't explain.

6) Message boards : Number crunching : The setting for "# of CPU´s" is getting ignored (Message 3761) Posted 3 Sep 2019 by vpf3 Post: I don't think it is project-related at all. Your BOINC client doesn't accept the input or it somehow recognized 12 threads/ cores. vpf3
7) Message boards : News : Server upgrade (Message 3558) Posted 13 Jul 2019 by vpf3 Post: Issue still existing... transient http error... again like before some months and before some months.

9) Message boards : News : Server upgrade (Message 3540) Posted 1 Jul 2019 by vpf3 Post: What's the status? When will be WUs available again?
10) Message boards : Number crunching : When will we get again WUs? (Message 3525) Posted 26 Jun 2019 by vpf3 Post: Edit: Never mind pipeline is filling up. Hi, I read that post before posting here. Sadly it contains unprecise informations: "later in this week". vpf3
11) Message boards : Number crunching : When will we get again WUs? (Message 3523) Posted 26 Jun 2019 by vpf3 Post: Hello, 20 of 22 machines are dry. No Wus anymore. When will we get next WUs approximately? vpf3
12) Message boards : Number crunching : Cannot Upload or Download Tasks (Message 3481) Posted 14 Apr 2019 by vpf3 Post: That is from a lot of connections that are currently made to the server. It works believe me. I have 21 computers working for U@H. Give it some time and it will normalize. vpf3
13) Message boards : Number crunching : Cannot Upload or Download Tasks (Message 3479) Posted 14 Apr 2019 by vpf3 Post: Works for me now. Thank you Krzysztof! vpf3
14) Message boards : Number crunching : Cannot Upload or Download Tasks (Message 3476) Posted 14 Apr 2019 by vpf3 Post: Same issue here can't download/upload. Issue seems to be the expired certificate. vpf3
15) Message boards : Number crunching : More wu to process (Message 3459) Posted 31 Mar 2019 by vpf3 Post: It seems like there is a WU per CPU (or more precise on CPU Threads) limit as well. 8 cores/ 16 Threads seems to be 128. Hosts with 4 cores/ 4 threads = 32. vpf3
16) Message boards : Number crunching : Cannot Upload or Download Tasks (Message 3454) Posted 30 Mar 2019 by vpf3 Post: Hi, don't think it is a problem only for you. And non-static IP adresses are common with ISPs. I get a new one assigned every 24 hrs or on restart of my router. So it is very common. vpf3
17) Message boards : Number crunching : More wu to process (Message 3453) Posted 30 Mar 2019 by vpf3 Post: Not sure what the overall limit is, but I get max for my best machine of 128. vpf3
18) Message boards : Number crunching : Cannot Upload or Download Tasks (Message 3447) Posted 29 Mar 2019 by vpf3 Post: Hi, I checked my logs too. I find similiar log entries (for all 20 pcs). Is the problem still present for you? It fixed itself after about 5 hours for me. I had more details in the log: master00 4029 Universe@Home 29.03.2019 03:24:24 Temporarily failed upload of universe_bh2_180328_258_396669604_20000_1-999999_670000_1_r52309694_3: can't resolve hostname 4028 29.03.2019 03:24:24 Internet access OK - project servers may be temporarily down. 4027 Universe@Home 29.03.2019 03:24:23 Started upload of universe_bh2_180328_258_396669604_20000_1-999999_670000_1_r52309694_4 test00 7113 Universe@Home 29.03.2019 06:25:42 Temporarily failed upload of universe_bh2_180328_258_443634557_20000_1-999999_635000_1_r478678539_2: can't resolve hostname 7112 29.03.2019 06:25:42 Internet access OK - project servers may be temporarily down. 7111 Universe@Home 29.03.2019 06:25:40 Started upload of universe_bh2_180328_258_443634557_20000_1-999999_635000_1_r478678539_2 slave01 6789 29.03.2019 04:29:34 Internet access OK - project servers may be temporarily down. 6788 Universe@Home 29.03.2019 04:29:32 Started upload of universe_bh2_180328_258_407829593_20000_1-999999_830000_0_r1625978979_2 6787 Universe@Home 29.03.2019 04:29:32 Backing off 00:02:35 on upload of universe_bh2_180328_258_407829593_20000_1-999999_830000_0_r1625978979_1 6786 Universe@Home 29.03.2019 04:29:32 Temporarily failed upload of universe_bh2_180328_258_407829593_20000_1-999999_830000_0_r1625978979_1: can't resolve hostname 6785 29.03.2019 04:29:32 Project communication failed: attempting access to reference site 6784 Universe@Home 29.03.2019 04:28:21 Started upload of universe_bh2_180328_258_407829593_20000_1-999999_830000_0_r1625978979_1 ... Hope it was a temporary issue. If not the admin should take a look on it. @Krzysztof: Was there an outage in the last 24 hours? vpf3
19) Message boards : Number crunching : Cannot Upload or Download Tasks (Message 3445) Posted 28 Mar 2019 by vpf3 Post: Hi, do you have more informations? A task name would be great. Reason I am asking is that I see no tasks for first user at all and a lot of cancelled for second user. Maybe server/ your client are kind of "out of sync". vpf3
20) Message boards : News : Problems sorted :) (Message 3320) Posted 6 Feb 2019 by vpf3 Post: Not sure what issue all the PI users have. My 20 PIs work fine. All 3B+, all current Debian Jessie 4.14.97, all working good.
