1) Message boards : Number crunching : Radeon R9 280X for MilkyWay@Home (Message 69417) Posted 31 Dec 2019 by gambatesa Post: From years for MW It's the best bang-for-buck.. 3x7970 costs less then a half of a Radeon VII and give the same credits (about 1400-1500k).. the downside is 3x power consumption (3/350W x gpu), a bigger psu needed and 3x heat to cool.. and with fans spinning always near to 100% they need to be clean and replace when needed (but it's a problem of all gpus)
2) Message boards : Number crunching : Finally getting new tasks only seconds after running out. May not be worth the hassle. (Message 69416) Posted 30 Dec 2019 by gambatesa Post: I installed the first clients . It's too early to evaluate the improvements but in the next days i'll keep monitored logs and RAC thanks for your help.. really appreciated for me and for the community.. A quick followup.. since i installed the modded 7.15 from Joseph Stateson my RAC increased consistenly of 8-10%.. No more idling.. all gpu back to work 24/7 Thanks Joseph for your work Now we still hope in an official fix (but wait will be easyer)

(Message 69271) Posted 20 Nov 2019 by gambatesa Post: I used VS2013 to build a new version of boinc "7.15.1" The boinc people have put together a nice package for building windows and also Linux. The latest version available for download is 7.14.2 Where can i download these new binaries?

8) Message boards : Number crunching : Delay in getting new work units untill all work units have cleared (Message 69105) Posted 22 Sep 2019 by gambatesa Post: Setup a 2nd gpu project with a zero resource share so when MW runs out it will get tasks and your gpu won't be idle while waiting for MW to refill the cache. PrimeGrid and Collatz are two projects that almost always have tasks, at PrimeGrid you can pick wu's that run very quickly like the MW wu's do and at Collatz if you do use the optimization codes the wu's will run much faster as well. This is just a workaround, not a solution.. developers must fix it This is for sure a server-side misconfiguration, in 15years of boinc it never happened with any other project
9) Message boards : Number crunching : WUs not downloaded in time - rig is idling - doing no work ... (Message 69093) Posted 20 Sep 2019 by gambatesa Post: when you ron out of WU the first deferred communication is always more or less 1.40minutes.. in this first stage it uploads the latest results (and don't downloads anything) then begin the second deferred communication of more or less 12minutes (can't remember).. the gpu is idling and then since no results to report, the downloads of 300wu begin this loop is always the same on all hosts.. next time i'll run out of WU i will post the exact times..
10) Message boards : Number crunching : Rx570 vs. gtx 1080, 1080ti, 2080 (Message 69075) Posted 19 Sep 2019 by gambatesa Post: I seem to do the work units in around 100 - 140 seconds for both my 1080 and 2080. And around 90 seconds for my 1080 Ti. Milkyway needs a strong FP64 GPU.. I don't have any nvidia but only AMD to compare.. a Radeon VII can complete 4WU in 40-45secs (10-11secs each) and a Radeon 7970/280x can complete 3WU in 100sec (33secs each), a 7950/280 needs 3-4 secs more
11) Message boards : Number crunching : WUs not downloaded in time - rig is idling - doing no work ... (Message 69069) Posted 19 Sep 2019 by gambatesa Post: Yes, this was reported in May. From the last result there needs to be a 10min period of no requests until the clients can get more work. https://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=4424&postid=68441#68441 I'm about to setup a script to turn off networking for like 11min, resume and do a project update, allow for 30min or so then repeat. That's not true.. if you report immediatly the last results and wait the first deferred communication interval of 1minute and 30seconds the new workunits will arrive..

(Message 69048) Posted 17 Sep 2019 by gambatesa Post: I tried the reccomended settings (1+1day) but situation is the same, this was from some minutes ago but some considerations.. The problem is not the idle when the queue is empty, the problem as highlighted is that when results are reported new workunits were not downloaded until queue is empty.. THIS IS THE PROBLEM, not the idling at empty cache.. If cache was refilled (3 results, 3 new WU) there will be no problems of empty queue Look: GPU Radeon VII - Host https://milkyway.cs.rpi.edu/milkyway/show_host_detail.php?hostid=775931 (3 Wu at same time) 72287 Milkyway@Home 17/09/2019 16:47:59 Sending scheduler request: To fetch work. 72288 Milkyway@Home 17/09/2019 16:47:59 Reporting 9 completed tasks 72289 Milkyway@Home 17/09/2019 16:47:59 Requesting new tasks for AMD/ATI GPU 72290 Milkyway@Home 17/09/2019 16:48:01 Scheduler request completed: got 0 new tasks 72291 Milkyway@Home 17/09/2019 16:48:02 Computation for task de_modfit_14_bundle4_testing_3s4f_3_1564052102_18057897_0 finished 72292 Milkyway@Home 17/09/2019 16:48:10 Computation for task de_modfit_14_bundle5_testing_4s3f_3_1564052102_18057819_0 finished 72293 Milkyway@Home 17/09/2019 16:48:18 Computation for task de_modfit_86_bundle4_4s_south4s_bgset_2_1564052102_18057556_0 finished 72294 Milkyway@Home 17/09/2019 16:49:36 Sending scheduler request: To fetch work. 72295 Milkyway@Home 17/09/2019 16:49:36 Reporting 3 completed tasks 72296 Milkyway@Home 17/09/2019 16:49:36 Requesting new tasks for AMD/ATI GPU 72297 Milkyway@Home 17/09/2019 16:49:38 Scheduler request completed: got 0 new tasks 72298 Milkyway@Home 17/09/2019 16:57:13 Sending scheduler request: To fetch work. 72299 Milkyway@Home 17/09/2019 16:57:13 Requesting new tasks for AMD/ATI GPU 72300 Milkyway@Home 17/09/2019 16:57:17 Scheduler request completed: got 300 new tasks Same problem with the second Host, here i have 10+10 Days: GPU 2x HD7970 - Host https://milkyway.cs.rpi.edu/milkyway/show_host_detail.php?hostid=801749 (3Wu per GPU, 6 at the same time) 122460 Milkyway@Home 17/09/2019 15:33:11 Reporting 6 completed tasks 122461 Milkyway@Home 17/09/2019 15:33:11 Requesting new tasks for AMD/ATI GPU 122462 Milkyway@Home 17/09/2019 15:33:13 Computation for task de_modfit_86_bundle4_4s_south4s_bgset_2_1564052102_17748961_1 finished 122463 Milkyway@Home 17/09/2019 15:33:13 Scheduler request completed: got 0 new tasks 122464 Milkyway@Home 17/09/2019 15:34:14 Computation for task de_modfit_14_bundle5_testing_4s3f_1_1564052102_17992266_1 finished 122465 Milkyway@Home 17/09/2019 15:34:14 Computation for task de_modfit_14_bundle4_testing_3s4f_1_1564052102_17999182_0 finished 122466 Milkyway@Home 17/09/2019 15:34:27 Computation for task de_modfit_83_bundle4_4s_south4s_bgset_2_1564052102_17998863_0 finished 122467 Milkyway@Home 17/09/2019 15:34:45 Sending scheduler request: To fetch work. 122468 Milkyway@Home 17/09/2019 15:34:45 Reporting 4 completed tasks 122469 Milkyway@Home 17/09/2019 15:34:45 Requesting new tasks for AMD/ATI GPU 122470 Milkyway@Home 17/09/2019 15:34:46 Scheduler request completed: got 0 new tasks 122471 Milkyway@Home 17/09/2019 15:47:21 Sending scheduler request: To fetch work. 122472 Milkyway@Home 17/09/2019 15:47:21 Requesting new tasks for AMD/ATI GPU 122473 Milkyway@Home 17/09/2019 15:47:28 Scheduler request completed: got 600 new tasks
13) Message boards : Number crunching : WUs not downloaded in time - rig is idling - doing no work ... (Message 69045) Posted 16 Sep 2019 by gambatesa Post: With a Radeon VII i can crunch 2WU at same time in about 20sec.. a queue of 300WU will dry in more or less 50mins.. and every 50mins i have 10-15minutes of idling.. Cache is set at 10+10days but it was 1+1days and before 0.1+0.1.. no difference for me on any host Probably problem is less noticable with slower gpus but for high end gpus penalty is of about 20-25%

16) Message boards : News : New Expanded Runs for Milkyway_nbody (08/06/2019) (Message 69011) Posted 8 Sep 2019 by gambatesa Post: Sorry for OT , but i'm still experiencing on all my host with various boinc versions a delay in retrieving new workunits. All clients requires cache of result to be empty and some minutes of delay before retrieving new workunits. With fast gpu such a Radeon VII it's very frustrating.. I'm experiencing this problem since months ago and it was already reported from other users in the past. When will be fixed?

18) Message boards : News : New Separation Runs (Message 68811) Posted 31 May 2019 by gambatesa Post: Thanks but this is something different.. the queue is empty since yesterday evening.. usually i can download about 2-300 wu per gpu (only when queue is empty as the issue you explained) but since this night the queue is completely empty and i always have the message "Scheduler request completed: got 0 new tasks " exept sometimes when downloads 2-10 workunits per host..

20) Message boards : News : Database Maintenance 9-4-2014 (Message 67803) Posted 8 Sep 2018 by gambatesa Post: Same here.. about 14000 validation inconclusive.. we have to wait Validation Inconclusive WU are steadily decreasing.. about 5500 in this moment.. There is always a beginning with 0 wingmans.. But is more evident if everyone run out of work and everyone start again from 0 There is no reason to panic.. this kind of validation queue is absolutely normal and that's why if you stop crunching today you continue to receive (decreasing) credits in following days..
