1) A nice mid-grade Boinc system with some cores and some or a gpu. What is your low bid on such a system (assuming we are ignoring Android Cellphones, Android Tablets and the ARM cpu branch of life)? This system is most likely running a Windows 10 OS, has at least 8 megs of ram (1 or more sticks), probably has anything from 250 GB of SSD to several Tera-bytes of regular HD. Has at least 1 discrete gpu. And it could even be a Laptop :)


$626. I'd go with Maximum PC's "Budget Build", a Ryzen 5 2600 and a GTX 1660 Super.

2) A higher end machine with at least 8 cores and maybe a couple of gpus. This machine could be doing serious image processing or other fairly heavy duty production tasks as part of its day job. What would like like a good set of options? This system is most likely running Windows 10 OS also.


No question on CPU (unless you're willing to up the cost a lot by going Threadripper...) Ryzen 3950X. If cost is a factor, the 3900X is at the "sweet spot." If you're not gaming, there's no need for ray tracing and I'd try to pick up a couple of 1080Ti GPUs for it - you can get the 2080s if the budget allows. Personally, I have little need for GPU other than BOINC and I'd go with two 1660Ti's. I'm looking to replace my current old photo editing box (5820K CPU and 780 GPU) and will likely get a 3900X and one 1660Ti, to stay in my budget, around $1200 (reusing a lot of parts).

I have 12 years today according to the web site, but I know that somewhere in there I "lost" my first account completely, so I'm guessing that I'm at least real close to 15 years now. I came here straight from RC5, anyway.

Can't claim to have been _productive_ during much of that 15 years though! A whole lot of activity up front (see my "number of posts" figure, compared to my abysmal "number of credits"!) then a long dry spell. But I'm hopefully back now! :-)

You need to look in the Number Crunching forum, there are a lot of threads on upload/download problems. If you don't see something that answers your question, post there including the following:

Quit BOINC completely. Launch BOINC. Select SETI in the "Projects" tab and hit Update. Leave it for at least 10 minutes. Go to the Messages tab and select all messages to copy. Paste them into your posting. This will give the necessary information for someone to help you.

You're using Menubar, so I don't know of a way to tell, other than the % complete when it _is_ running.

All you do is add the two new files; BOINC takes care of the rest, will delete what it doesn't need (4.18) and keep what it does (the WUs).

See this thread for info on the Altivec-optimized SETI application. There are several currently-active threads in the Number Crunching forum about SETI_Enhanced.

Are you looking at seti_4.18_darwin_ppc (or something like that, that name is from memory) in Activity Monitor? That is what should be getting 80+% of your CPU, not BOINC Manager, which is just a "scheduler and GUI" for the science application.

The Wiki is the source of all BOINC knowledge; I'd be happy to answer any specific questions, but for "how does all this work", well, I'd be here all day and all I'd be doing is retyping the Wiki... :-)

I think we're missing each other, I didn't realize you were already on CPDN and looking to "improve" it, I was just talking about initial install. CPDN does _not_ have any "3rd-party" applications available, Altivec or otherwise. They _do_ require you to download some "extra" library files if you're on Mac, before the standard application will work. (Unless they've fixed that very recently...) Their sulphur WUs have a deadline of a year or so, but on my PC with a 30% share, 1000+ hour total time-to-completion, I'm getting one "trickle" (161 credits) per day. With CPDN, it's the "trickles" and not the completion of the result that matters most, until deadline.

As long as you are returning one CPDN trickle every three (calendar) days or less, you're ok. (I would actually strongly advise every TWO days.) If you look at the dates on the trickles you've returned (you'll have to drill down through the WU on their site to see them) and you see them coming in slower than that, then to avoid problems later, you probably need to increase the resource share a bit. If your Mac is too slow to return a trickle every three days, if it's _close_, you may be able to get by, but at some point the scheduler will switch you to "CPDN only" in an attempt to meet the deadline. If you aren't even close... it's probably better to kill off CPDN early, letting them reissue the WU now, rather than waste a lot of time on it to only have to abort it in a few months.

Some people use CPDN _solely_ as a "backup" project for network outages. They fully expect to let it run only when nothing else is available, just for the "trickle credits", and know they are going to abort it when the deadline approaches. I can't go along with that, they're only hurting the CPDN project just to keep from losing any BOINC credits during downtimes. If someone has "not losing credits" as their goal, then a 10% share of something with "reasonably long" WUs, like Einstein or Rosetta, and a 5-day cache, is a much better approach. CPDN is a great project; but a lousy "backup" project, imho.

Thanks; it worked today. Now I have a folder containing a Terminal document called "seti@home-G4-a5" and a tiny file called "app_info.xml". The former doesn't seem to do anything when I run it, and there's no other installer or ReadMe. Could it be a corrupt download?


No - that's the right stuff. There should have been a "how to install" document around there somewhere... but it's extremely simple.

Quit BOINC. (Some instructions advise finishing the WU in progress first, as it _may_ be errored out by the change in apps, but I have had no problems. If it's at 90% though, you might want to let it finish.) Find the /Library/Application Support/BOINC Data/projects/setiathome.berkeley.edu folder. Copy seti@home-G4-a5 and app_info.xml both into this folder. Restart BOINC. That's it!

At the moment it runs under emulation, and pretty slowly (and screensaver doesn't work). However, an Intel Mac version of both BOINC and SETI have been compiled and are currently being tested. Apple jumped the gun and shipped six months faster than expected...

Where are you looking? I see your account showing 836 Classic WUs. You have attached a computer to the project, and are currently working on your first BOINC/SETI WU.

Note my signature below; BOINC and SETI "Classic" are separate lines in the stats.

compared to 190


I believe there is still a "conversion factor" that has yet to be added... which SHOULD make it quite a bit more than 190 for that angle range.

(how i love my 10 day cache). But theres only 1 for CPDN thank God.


a) Set CPDN for "no new work" - you REALLY don't want to get a second one on there...

b) If you have your machine set for a 10 day cache, you are forcing it into EDF mode ALL the time - therefore it will NOT do "round-robin", SETI and CPDN. It will do only SETI, continuously, until the cache is empty. Then it will do CPDN for 1/3 as long as it ran SETI, then it will get more SETI work, and repeat. This is NOT GOOD. Lower your cache size. To work properly with two projects, it MUST be 5.6 days or less. Let's face it - with 2200 hours of CPDN to do, you are _not_ going to run out of work if SETI is down for a day or two.

c) Once you've lowered the cache size, it will still do SETI-only until the work on hand drops below 5.6 days.

Post:
The "stock" SETI application for the Mac is basically just the Linux/Unix version recompiled. If you'll see the thread here you'll see info on an Altivec-optimized version. I don't know what Activity Monitor shows on a Dual, but you _should_ see each instance of SETI taking 80-90% of one CPU; if AM "adds it all up", then each will show 40-45% of the total system.

If you go the optimized app route, you will have to _uninstall_ it when SETI_enhanced is released, so BOINC can automatically download the new app.

It looks like you created a new host record when you upgraded from OS X 10.3 to 10.4. If they will not merge, then when all the results have timed out and been deleted on the older one, you will be able to delete it.

Is the CPDN Altivec-optimized for Alti-G4? Does it install through terminal?


CPDN is barely Mac-functional, actually... it DOES work, but you have to download some additional libraries manually before it will. It's a standard BOINC app otherwise. My fastest current Mac is only a Mini, so I haven't tried to run CPDN on it; it's on my Windows box. If the graphics are as good on a Mac as they are on the PC, I'd call it the second-best graphics after Rosetta (which is Windows-only for graphics so far, they're still debugging).

For any CPDN info, I'd go ahead and create an account over there, read up both on their site and in the Wiki (it has a _lot_ of CPDN info in it) and then give it a try.

This is a strange one... and one of the _few_ cases where I think a "reset" is in order, or possibly even detaching and reattaching to the project. (Assuming this is the same error you've been getting for a month.)

Different issue; this is saying that for whatever reason (debt to other project most likely), the scheduler does not WANT work.

No, it appears to be totally blank: if there's "gibberish" there it comprises only spaces, tabs, &c.


One more thought; if you exit BOINC and open the file /Library/Application Support/BOINC Data/client_state.xml with TextEdit, the fourth line is "domain_name". This is where the name is stored on the local computer to be sent to the sites; if that is blank for some reason, you can plug in a name (no spaces!) and it _should_ update the projects next time it contacts them...
