WCG Project Updates, December 2019 Another month of research team updates from the World Community Grid forums. The text of all updates is from Caiti Larkin, WCG Admin. Note: WCG entered a lull this month, with one project reaching completion, and three on hiatus while researchers do analysis and work out what their next targets will be. Additionally, the Africa Rainfall Project has been fully online for a month, but its structure means that there are comparitively few in-flight workunits at any given time -- around 1900 per day. (For comparison, MCM1 averages 675kWU/d) Africa Rainfall Project We plan to start mini-updates for ARP in January. Microbiome Immunity Project We wrapped up our call with the research team just now.
Smash Childhood Cancer [This update is from November but happened late, so I missed it last month.] Highlights from our monthly SCC research call:
Help Stop TB Had a quick call with the researchers today, with no significant updates except that they're working on a project update for us and continuing to get their new team member up to speed Fight AIDS @ Home Phase 2 Updates from our monthly call with the researchers:
Mapping Cancer Markers We just wrapped our monthly call with the researchers.
OpenZika Just wrapped up our monthly call with the research team.

In Asteroids@Home, Team Something Awful is looking great here. We have broken into the Top 50 in recent average credit for the first time in my memory. It was just this last month that we broke the Top 100. We're also #331 in total credit too, and that's been going up substantially. A lot of these teams have fifty or so members in them, but are really just one or two people doing all the recent work. Asteroids is one of those projects that seems to run out of WUs every week or so. Apparently, this is attributed to availability of hard drive space on the server end. Since this is generally my only project, what I do to make sure my computers always have work in the meantime is I tell my BOINC clients to store work up to five days in advance: ![]() Don't do this if you're doing other projects as well, especially Africa Rainfall.

I tried joining Asteroids today, but the auth server appears to be busted in some way. I did rejoin crunching on Einstein@Home after doing a PSU swap, getting a node back online, and slotting my spare GTX 750 Ti into it. I attached that machine to GPUGrid as well, but only to crunch "small" jobs, and I think that perhaps none exist at the moment. Either that, or it's still busted on Linux? ![]() Pushed out a Homefarm update as well: v2.0.1 has fixes for Arch switching the compression on their packages. Previously the local repository tooling had assumed eveyrthing would be an xz file. Thank you for attending my TED talk.

I recently built a new system around a Ryzen 3700X and a Nvidia 1650 super and joined it to Einstein@Home. AMD's built in autoclocking seems to allow me to run tasks in the 4.2ghz range with around 90watts consumed by the CPU(65watt TDP CPU). Seems good to me. Im curious what to expect in points per day with this type of CPU. Right now it seems to be in the 20k/ppd range after just a few days. Will need to give it some time to stabilize I guess. I wonder what it takes to get to the 100k+ ppd range. Multiple powerful GPU's or ??? Are there other project with more ppd incentives I could target? Have been looking at climateprediction.net and possibly WCG. I seem to be unable to create an account on climateprediction.net via the BOINC manager at the moment. Its been telling me account creation is disabled. Not sure if its due to them having a lack of work. Looking around their site all their projects seem to have no WU's available except for the linux only "UK Met Office HadAM4 at N216 resolution" project. I might dual boot my system into linux so I can run these types of projects. Open to distro recommendations and dual boot advice. I tried installing the boinc client in a fedora VM and it seems as though the package is not been kept up to date. https://www.climateprediction.net/support/server-status/ https://www.cpdn.org/apps.php

Hmm. It appears my machine IS a 100k+ points per day machine. When I rebuilt the machine I re-used the old windows install and that meant the computer id on BOINC didnt change. The daily avg is pulled down by my old WU's and wont reflect an accurate avg until I rebuild or the last of the old WU's stops contributing to the daily avg number.

It's the points credited for any workunit on which you were the primary or a wingman, validated in the last 24 hours from the point of view of the project server. There can be a decent amount of fluctuation day-to-day, even if your machine is crunching the same project, 24/7. So BOINC points are only generally useful as a performance indicator, when considered as a trendline across timescales of a week or more. Anyway, what kind of incentive are you after? quote:I seem to be unable to create an account on climateprediction.net via the BOINC manager at the moment.

I just created an account here: https://www.cpdn.org/create_account_form.php then I was able to link it up to my BOINC manager by selecting the climate prediction project in the project list and entering my account details. It doesn't look like a very active project with only ~2k WU's ready to be sent out to ~10k computers.

Tweeter99 posted:I just created an account here: https://www.cpdn.org/create_account_form.php Thanks for the direct link. I poked around for five minutes myself trying to find the direct way and didnt find it. The WCG project seems like an interesting challenge since its 1.) Linux x86_64 only for the OpenIFS work units. 2.) The work units is this silly weather modeling software written in FORTRAN 3.) The memory usage per WU is approaching 4GB/unit which makes its difficult to run 8+ WU's on a machine unless you have gobs of ram. 4.) The WU's take 7+ days to execute It seems like you need serious dedication to meaningfully contribute. Lots of linux janitoring and probably running retired server hardware at home. Whether this is a good use of any ones resources I have no idea. I figure someone has to do it. It vaguely maps back to my day job of running terrible software in the enterprise. Also its outside the reach of a lot of casual boinc users who only run the windows gui in the background. Another thing I was fooling around with. I started up a copy of boinc in Google Compute Engine. I was hoping to abuse some of the preemptable vm instances to get some cheap compute. I experimented with the linux hibernate to disk feature to try preserve running tasks from having to start over from their checkpoint. You can see one of these instances here https://einsteinathome.org/host/12802771 So far the return seems abysmal. Ill burn through the $300 credit in a few months and maybe only get a few thousand points for the effort. If someone has any tips on getting boinc points from da' cloud I'd like to try some other angles.

I have a small cluster of 8 Raspberry Pi 4's running a Kubernetes (k3s) cluster on stock Raspbian. I've got 7 of them (all except the master node) running the BOINC client and attached to Asteroids@Home, Einstein@Home, and SETI@Home. Mainly went with those since they all had ARM support. For setting up the container spec, I just used the stock BOINC client docker image and added the following: - Run clients on the host network so that I can just connect to each instance from the UI using the node IPs. - A ConfigMap containing the account XML snippets. With this they seem to immediately attach to the accounts I'd created. These could have been stored as Secrets but I'm only putting the weak credentials in them so I don't really care. - A separate "boinc-ui" Secret containing the password for connecting to the clients from the UI. - A persistent volume for holding the workloads/configs. Anyway here's what I ended up with, feel free to copy and tweak as needed. For example this assumes arm32v7 images and a local path provisioner for the persistent volumes (included by default in K3s). I'm mainly just happy that it was straightforward to get auto-attach working: code:
e: remove autoinserted url tags, thanks radium

Noticed that the BOINC jobs were running at low CPU priority (19), so figured it was fine to try running it on the master (pi-01) too. To do that I edited the earlier K8s spec to have replicas=8 and commented out the nodeAffinity rule.code:

mdxi posted:What kind of power supply are you using? I've thought about this kind of thing before, but I am very dumb with electricity and therefore terrified of custom PSU type stuff. It’s a Mean Well RSP-500-5. One downside with it is that the fan is always on in the 5V model. I ended up replacing the horribly loud stock fan with a Noctua A4-20 FLX. I would have preferred a PSU that just automatically turned off the fan when it’s not needed. In this case the PSU is way overkill for 8 RPis so the fan isn’t doing much and frustratingly could just be turned off entirely most of the time if the model had supported that. An issue with 5V power is voltage drop, where 5V from a power supply might easily be 4V by the time it reaches the device. At higher voltages like 48V a drop of 1V isn’t a problem but when you’re starting from 5V it’s a big deal proportionally. Voltage drop is caused by resistance in the wire, and gets worse for thinner/longer wire sizes and also for higher loads/amps. The RSP-500-5 has a potentiometer that can be adjusted using a Phillips screwdriver to add or remove a volt or so from the output voltage. This can be used to counteract voltage drop by increasing the voltage at the source. But there’s some risk of cranking it up too much because voltage drop is proportional to load - if the RPis are idle then the voltage at the RPis will go up again, until it’s close to the PSU voltage. So it’s important to ensure that the PSU voltage isn’t increased beyond what the RPis could handle if they were getting all of it. In my case I found that with the RPis all at 100%, I was seeing around a 0.7V-0.8V drop. I cranked up the PSU voltage to about 5.65V (measured frequently using a multimeter across the PSU output ports) at which point the RPis were getting around 4.9V (measured at a terminal bus fairly close to the RPis) and were no longer showing the low voltage indicators. From some searching it looks like the RPis should be okay up to around 6V so I figured that up to 5.65V reaching the RPis when they’re idle would be okay. Note that I’m powering the RPis using their USB-C port which is supposed to provide some voltage protection, whereas if I was powering them directly via header pins then it bypasses the voltage protection and this becomes much more delicate. RPis give two indications that they are running in low voltage mode, which makes them run much slower: - The red power light turns off but the RPi is still running. - A warning like this in dmesg: code:
code:
- running boinc or some other benchmarks on the RPi to bring up the amps/load (and also the voltage drop) and checking whether the red light turns off on the RPi. If the red light stays on then you’re done and don’t mess with it - regularly checking the voltages using a multimeter at the PSU and at the RPi and making sure the voltage on both sides never exceeds a level that would damage the RPi (again, the PSU voltage shouldn’t exceed what the RPi could take directly, because the voltage drop will go away when the RPi isn’t busy) - very slowly turning the PSU potentiometer adjustment with a screwdriver, checking voltages at the PSU and RPi periodically to make sure the voltage is doing what you expect - stopping once the red light on the RPi turns on again, indicating that the RPi is happy with the voltage it’s getting, OR - stopping once the PSU voltage is getting close to RPi limits in which case it’s not safe to continue. In this case voltage adjustment alone isn’t enough and you need to back off the voltage and just get shorter and/or thicker gauge wire to power the RPi before trying again However depending on your local law you may need to seek the help of someone who is licensed to do electrical work before doing any of this, and do not mess with electricity if you are not confident that you know what you’re doing. In the best case screwing up means replacing a fuse but in the worst case it can lead to damage, death, or both. As mentioned above it may be simpler to resolve voltage drop by getting shorter power connections which would reduce the problem at its source.

WCG stats for my team as of this evening:code:
* Started with one machine, on 14 Jan 2018 * Took just over one year to reach 25 years of compute (19 Jan 2019; up to 3 machines at that point) * Hit 50 years just under 7 months later (12 July 2019; 4 machines online; one upgraded to 3900X) * A little under 4 months later (3 Nov 2019) was 75 years. All 4 machines were 3900X by this point, the final 2700 having been swapped out a week before * Just over 3 months later, today, 100 years. 6 machines crunching; four 3900Xs and two 2700s I'm effectively out of space and power, so from here on out I'm only getting more CPU through upgrade cycles ![]()

Oh, and this should probably be in the OP as well. In other Asteroid news, we have risen to #278 in Total credit. We have surpassed teams Anime@home and EG Union (aka Elite Games), two BOINC teams that rightfully don't deserve to be above us. EG Union is a rival player group in Elite Dangerous. A few years ago during the Dangerous Games event, goons came in second place with only EG Union beating us. This latest movement puts us justly on top of them where we belong (least when it comes to mapping real asteroids).

It's been a progression! I included the quarter-century times to show that I built up this capacity, and that it took me time to do it. This has latched onto some part of my brain and re-ignited the hardware obsession that I thought went away in my late 20s. I think what's driven it for me is having a sense of purpose to attach things to. I had gotten over hardware-for-hardware's sake (I'm not saying there's anything wrong with that sort of exploration; I'm saying that I have been there and done that, and no longer found it compelling). My personal needs were so slight, compared to the capabilities of modern hardware that I had mostly become interested in low-power/high-efficiency computing. But getting into grid computing changed my personal definition of efficiency from "does what i need in as few watts as possible" to "does as much science as possible per unit time, for a reasonable number of watts". Of course, that hinges on the definition of "reasonable" and currently I'm defining that as "around 100W for the overall system, plus another 100W for systems with GPUs". This is a huge amount of electricity compared to, say, a Raspberry Pi, but the results are going to be hugely scaled up as well. And what really made me OK with that sort of power usage was realizing that until the mid-1990s when CFLs started to become mainstream, most American homes were lit by incandescent lamps in the 60-100W class. My compute farm is a massively better use of that energy than 7 100W light bulbs. I'm looking forward to Zen 3 and 4, and seeing what kind of improvements I can manage to get from them. I'll also be happy when Intel finally gets their poo poo together and comes back with a reasonably priced high core count part, now that AMD has changed the game. Historically no one has been able to touch them in the lower power arena (without going down a performance bracket to ARM), so I'd be happy for them to be back in the game to keep AMD from getting lazy again. Really, it's just fun to be paying attention to advances in hardware again, and to have found something genuinely useful to do with computing as a hobby.
