22) Message boards : Number crunching : Double your task throughput on Linux (Message 4638) Posted 23 Feb 2021 by mikey Post: From eyeballing my results from windows vs ubuntu I reckon that universe@home is 3 times faster on ubuntu and einstein@home is 4.5 times faster on ubuntu. It looks likes rosetta may be faster on windows and the other projects I run seem to be similar on windows and ubuntu. A pity I can't get Roblox (the kids game) to play on ubuntu then. Could be the overhead Windows imposes on everything as opposed to the much smaller Linux overhead.

24) Message boards : Science : First black hole ever detected is more massive than we thought (Message 4636) Posted 23 Feb 2021 by mikey Post: New observations of the first black hole ever detected have led astronomers to question what they know about the Universe's most mysterious objects. Published today in the journal Science, the research shows the system known as Cygnus X-1 contains the most massive stellar-mass black hole ever detected without the use of gravitational waves. https://phys.org/news/2021-02-black-hole-massive-thought.html ==================================================================== With a mass originally estimated at 15 times that of the sun, Cygnus X-1 is one of the most massive and most luminous of the X-ray binary systems known in the Milky Way. New measurements have now raised that figure to 21 solar masses. The makeover does not change the overall perception of the cosmos; Cygnus X-1 is still a black hole, an almost science-fictional manifestation of Einsteinian weirdness in celestial reality. But the details of how Cygnus X-1 became a black hole are now in doubt. “A significant change in the mass of such a classic and historical astronomical source is a big deal (at least to astronomers),” Daniel Holz, a theoretical astrophysicist at the University of Chicago who was not part of the study, wrote in an email. Also by email, James Miller-Jones of the International Center for Radio Astronomy Research at Curtin University in Australia wrote: “We realized that a 21-solar-mass black hole was too massive to form in the Milky Way with the best existing estimates of the amount of mass lost by massive stars in stellar winds.” https://www.nytimes.com/2021/02/18/science/cygnus-black-hole-astronomy.html Uh oh someone has to go back to the drawing board as to how something that big can form where it is...maybe it was there before the MilkyWay Galaxy gathered around it? We know Galaxy's move thru Space maybe it's a meeting in the dark between us and it.
25) Message boards : Number crunching : Upload fails (Message 4332) Posted 28 May 2020 by mikey Post: Good luck. Installing VirtualBox should be as easy as installing BOINC. Both are in the Ubuntu repositories. Open the software Center, search for BOINC and VirtualBox, install. Then run. I do not know if you need to reboot because of Virtualbox so that's something to consider when running of the USB. Anyway, try installing Virtualbox first and then BOINC and see if it works. If you encounter issues, feel free to post here! Thanks for your help. I'll get round to this eventually, but have been too busy with other things, I'll post the speeds I get on the 5 projects I use when I get Linux running. If you use the Synaptic software installer it shows the Virtual ox stuff in with the Boinc stuff, you have to look for Synaptic, sometimes harder than others, but it's built into most Linux Distros. It will also show you the dependency files it needs to install your choices as well.
26) Message boards : Number crunching : Getting a 196 (0x000000C4) EXIT_DISK_LIMIT_EXCEEDED error (Message 4329) Posted 26 May 2020 by mikey Post: Guess not. One wingman finished it with no issues. Could have been an issue where the previous task wasn't cleared from the slot. Boinc wiki says error code 196 means: ERR_WU_USER_RULE -196 BOINC tries to send the client this result and fails because: result needs more disk/mem/speed than host has already sent a result for this WU no app_version available https://boinc.mundayweb.com/wiki/index.php?title=Error_code_-191_to_-200_explained Maybe that comes down to lack of free drive space I don't know but to me that makes sense.
27) Message boards : Number crunching : Upload fails (Message 4277) Posted 9 May 2020 by mikey Post: Is there a way to automate "Retry now" so as to force the uploads? How about Autoitscript? The backoff time is designed to not keep banging on the door of the upload server so others have a chance to get theirs in too. Years ago Serti did a test and found it took like 20ms for the Server to connect with each pc and then around 20 seconds to tranfer the data and then another 20ms to close the port and get ready to open it for the next computer. With over half a million pc's per day there just wan't enough time in the day for everyone to connect as often as we users wanted to so they designed the backoff, and allow bigger caches, to slow things down a bit. With todays always on internet people have smaller caches, sometimes a zero cache so it's a do a workunit, return it and get another workunit, meaning ALOT more of us trying to connect to the Server. Unfortunately there are some things you just can't speed up without MUCH more expensive hardware and most Projects don't have that kind of money. That's the long answer, the short answer is yes but most Projects would prefer you not do it as other people who can't get thru will leave, one person has already done that here. Your RAC will not suffer very much and you may even get a slight pop once the Pentathlon folks are done sending in all their units.

We may be looking at different versions of ULX, Krzysztof said he'd made them smaller. Or I'm looking at a different CPU - I have 4 wildly different computers, I just glanced through my completed tasks on the server and took a rough average. This is using a NVIDIA GeForce GTX 1080 Ti (4095MB) driver: 390.13 OpenCL: 1.2 Using a what?! I thought Universe was CPU only? Just checked my preferences on the site, there is an option for AMD, but I don't think it does anything. I've switched it on just in case! But there's no Nvidia option. YES YOU ARE RIGHT...I guess I'm having a VERY bad couple of days at posting, I am NOT using my gpu's here ONLY my cpu cores!!!
30) Message boards : Number crunching : Upload fails (Message 4261) Posted 8 May 2020 by mikey Post: If they had disabled the ULX tasks that means there may not have been nearly enough BH tasks since they are shorter. Right now the Server says it has 625k BH tasks available and almost 32k ULX tasks in progress with zero available, we would need that number from a few days ago to get a better idea. Shorter?! The ULX I've seen are much quicker to process than the BH ones. 2500 seconds vs 15000 seconds. 2,537.91 2,517.00 100.00 Universe ULX v0.15 x86_64-pc-linux-gnu 4,756.02 4,756.02 pending Universe BHspin v2 v0.19 x86_64-pc-linux-gnu You are sorta right...my BH tasks DO take longer than my ULX tasks but only twice as long This is using a NVIDIA GeForce GTX 1080 Ti (4095MB) driver: 390.13 OpenCL: 1.2

32) Message boards : Number crunching : Block ip for bunkering? (Message 4253) Posted 8 May 2020 by mikey Post: Hello im wanting to block universe's ip address on kaspersky for the Pentathlon anyone able to help ive only got the one PC so working on multiple crunches. I have found the "Add packet rule" page just really need the settings? Regards Alan You could do it in your router too, they have an upload and download webpage, or you just block the whole Ip address.
33) Message boards : Number crunching : Upload fails (Message 4252) Posted 8 May 2020 by mikey Post: Whoa there partner! You had best hold off until Tuesday on making new ULX tasks! Monday you will be getting hammered again with all the final bunkers! :D In the future, if you get notified you will be in a competition, you may wish to remove all ULX tasks in advance. ;) (I don't know that you did get notified, just IF you get notified). I don't know about Universe, but Rosetta which is also in the competition has the same number of tasks in the field as they always do. How come everyone went mad on Universe but not Rosetta? I think it's more the ULX that changed the load, not the Pentathlon. Rosetta was pretty lucky because of COVID. The load from people that wanted to run a BOINC project vs f@h caused they to up their output. Considering a large portion of the current pentathlon members were already running rosetta, it didn't cause nearly the issues. MOST of the time Projects get notified that they were selected to be a part of the Pentathlon about a week ahead of time. Sometimes Projects say 'no' but it's proably too late and they suffer for it, I have no idea if Universe got notified or what they said if they did. IF they had disabled the ULX tasks that means there may not have been nearly enough BH tasks since they are shorter. Right now the Server says it has 625k BH tasks available and almost 32k ULX tasks in progress with zero available., we would need that number from a few days ago to get a better idea.
34) Message boards : Number crunching : Upload fails (Message 4251) Posted 8 May 2020 by mikey Post: I had 4 WUs that were stuck and couldn't upload after they were done and crunched. But I did get 3 of them to manually upload via the "Retry Now" button on the Transfer tab in Boinc advanced view desktop program. The 4th WU is having trouble. I have clicked retry now 5 times, but it just defaults to retry every 3 hours. If I click on the properties of the stuck WU it says. ........ Application Universe BHspin v2 0.19 Name universe_bh2_190723_308_1524908476_20000_1-999999_910100 . They are only sending out BH units right now as they are very small compared to the ULX units so upload and download very quickly. During the Pentathlon alot of people got the ULX units and they can be much bigger so take longer to upload. Add in that alot of people downloaded 7 days worth of tasks and didn't return them until the last day, it keeps others in the dark about how well you are doing, it is a 'race' of sorts. The back-off thing is a part of Boinc but I think the problem is with the Project not giving the Server enough time for each transfer to finish. Mine get to 100% and then sit there and back-off, I click retry and it goes to 0% and then back to 100% as it resends the whole data set again and then backs off again, rinse and repeat. The Server seems to be closing the connection before it recognizes it really does have the data.
35) Message boards : Number crunching : Upload fails (Message 4249) Posted 8 May 2020 by mikey Post: I think you are not right. The Pentathlon generates awareness and motivates many people for more crunch power. For a short time period. An maybe new boinc user use boinc after the race. Beside of that it is fun. Join a team, go to their forum. I'm not so sure. Don't they just attract people who are already doing Boinc? I can't see a non-Boincer spotting the pentathlon and doing it. How would they even hear about it? I run 5 Boinc projects, and have been on Boinc since it started, and I didn't know about it until it was mentioned in here. . Pentathlon's often get members of a Team to try new Projects, you may have never crunched here before so during the Pentathlon you do and say 'hey that's cool I think I'll stay for a bit'. They are not really designed to get 'new' crunchers just people to try 'new for them' projects or return to old ones.
36) Message boards : Cafe : Can't create new team (captcha) (Message 4217) Posted 7 May 2020 by mikey Post: Team creation is fixed. You must have some credits to create a team. Great but how much must I have? Total credit 12,569,167 Recent average credit 15,658.27 And the link to create a Team is gone and a search does not show the Team I'm looking for nor a link to create one!! And before you ask NO the Team I am on is not the one I WANT to be on.

38) Message boards : Number crunching : Odd performance on different computers (Message 4190) Posted 5 May 2020 by mikey Post: Hi, I'm crunching bh2 spin on several different types of computers and I have a very odd performance :) i7-3770k 3.7GHz, 4c8t, 32GB RAM (limited to 8GB in LXC, 4 tasks in parallel) crunches a task in less than 2 hours Ryzen 2700 3.3GHz, 8c16t, 32GB RAM (unlimited memory, 12 tasks in parallel) crunches a task in almost 3.5 hours?! PIne64+ 1.152GHz (Cortex A53, 4c4t, 2GB RAM, 4 tasks in parallel) takes about 16 hours (I can understand that one, slower cores and very slow clock) why is Ryzen so much slower when it is much newer? Is there some compile time flag optimized for Intel? I've even tried disabling smp on the Ryzen machine but no change there, still over 3 hours per tasks. Cheers Ashley :) On the i7 youhave 4c8t and you run 4 tasks at a time...time to crunch under 2 hours on the AMD you have 8c16t and you run 12 tasks at a time...time to crunch almost 3.5 hours Notice anything funny there...you are running too many threads on the AMD and are using the virtual cores for 4 of the tasks reducing the efficiency of each task, cut it back to 8 threads at a time and see if it doesn't speed up alot.
39) Message boards : Number crunching : No WU (Message 3978) Posted 5 Jan 2020 by mikey Post: Not sure how reliable the status page is. It seems to always say tasks ready to send = 2. Rather unusual for a BOINC project to run dry which makes me wonder how serious these people are ? Lots of projects run short from time to time, it depends on their funding levels and if they do it themselves or if they depend on grants etc. The more independent the project the more likely it is to run out of tasks at times. Add in the hardware problems and you have times where most projects will go down for a short to longer period of time.
40) Message boards : News : Server update (Message 3977) Posted 5 Jan 2020 by mikey Post: Hello Peter and Bill, thank you both for your help. I found a button on the einsteinathome website about that consent und it has the default "No". I changed it. Now I have to search in all the other projects too. Thanks for the list, Bill. The biggest problem is there is there is no standard place they put it, so you have to search thru everything to find it at each site.
