Our best guess right now is that GCW-Sieve has about a year to go before it gets shut down. It's way too early to know whether it will shut down permanently or temporarily. We may eventually start testing additional bases, and if so, we'll need to sieve those bases.

Thanks for the heads up.

I just enabled the project again, so that I can get up to the gold badge before GCW-Sieve gets shutdown.

How can I run more than one GCW Sieve task at a time ?
When running one task, I see my system uses only 18% of its capacity
(i7 6700 @3.4 GHz, 4 cores, HT on)

I currently use an app_config.xml to control llrxxx applications, but I don't know how to set it for GCW Sieve (actually, I don't even know if it is possible to do so)

I'm using this in app_config.xml and it works

<app> <name>gcw_sieve</name> <max_concurrent>2</max_concurrent> <fraction_done_exact/> </app> <app_version> <app_name>gcw_sieve</app_name> <avg_ncpus>1</avg_ncpus> </app_version>


App_config is not needed at all for GCW-Sieve. Let's take this line by line...

<max_concurrent>2</max_concurrent>


If you want to use all the available cores, that's BOINC's default, so this statement is not needed. Delete it.

<fraction_done_exact/>


This is never needed at PrimeGrid. We set this on the server side, so it's redundant to set it on the client side.

Since that's the entire contents of the <app> block, we can remove it entirely. Now for <app_version>...

<avg_ncpus>1</avg_ncpus>


Again, this is the default, so it's redundant. We can remove it. Since that's all that was in the <app_version> block, it can be entirely removed.

And now there's nothing left to put in app_config.

Indeed, there's no need to touch app_config.xml.

I had set "Use at most 12.5% of the CPUs" in BOINC Manager and this was limiting the number of simultaneous GCW Sieve to 1.

Since it seems that tasks done has gone 25% after this post (excluding the ESP challenge when it went down) and a month has passed, has the estimation of time remaining changed? Could sieving for some bases be shut down before others?

Time remaining is a fuzzy value as the optimal sieving level depends on what kind of CPUs we assume are running both sieving and LLR. It's less than a month since Mike's first post and the deadline is still more or less a year away.

Yes, we have individual control over which bases we sieve and it's likely that some bases will be shut down earlier than others.

Have there been any considerations as to which project is going to be selected as default when new users join Primegrid?

Perhaps PPS-sieve?

You ask a VERY good question.

We discussed this last month, and while we didn't make any decision, the two most likely candidates are PPS-Sieve and GFN-16. The reason PPS-Sieve isn't the obvious choice is because the tasks are rather long (because of the GPU tasks) and we won't really need any of this sieving for many, many years. The PPS sieve is way ahead of the LLR effort.

We discussed this last month, and while we didn't make any decision, the two most likely candidates are PPS-Sieve and GFN-16. The reason PPS-Sieve isn't the obvious choice is because the tasks are rather long (because of the GPU tasks) and we won't really need any of this sieving for many, many years. The PPS sieve is way ahead of the LLR effort.

Partner up with SRBase and sieve their ranges :)

We want to avoid using LLR or any other AVX/FMA-capable project as a default project. On modern Intel CPUs use of these features consume more power, produce more heat, and make more noise (from fans speeding up) than unsuspecting users might be expecting.

That leaves PPS-Sieve and GFN-16 through GFN-20 as the only options.

Or GFN16 CPU. No AVX necessary.


Didn't I say that in my initial answer to the question? PPS-Sieve or GFN-16 are the most likely projects to be the default after GCW-Sieve.

Message 117633 - Posted: 30 Apr 2018 | 14:43:23 UTC

It seems that 321 and Cullen/Woodall are only sieved to half the N level as most of the other LLR projects. While all the conjectures and GCW are sieved to either n=50M or, in the case of bases other than 2, 15 million digits, 321 and CW are sieved only to n=25M.

At some point we will need to restart both of those sieves in order to sieve 25M<n<=50M. It's not an urgent need, and we certainly have at least a few years before it's a problem, but 321 sieve would make a good default CPU project and CW sieve would make a good default GPU project if we had an AMD app to go along with the existing Nvidia app.

In theory, 321-sieve would be a better choice for a default CPU app than either PPS-Sieve or GFN-16, so this is something we're likely to give a lot of thought to.

Yeah, everyone wants to see old projects reopened to get that next badge, or to be able to get a badge that closed before you started. I have no doubt that restarting any suspended project will be very popular.

At some point we will need to restart both of those sieves in order to sieve 25M<n<=50M. It's not an urgent need, and we certainly have at least a few years before it's a problem, but 321 sieve would make a good default CPU project and CW sieve would make a good default GPU project if we had an AMD app to go along with the existing Nvidia app.

For those of us who are newcomers and did not have the opportunity earlier to work on these two badges, this is awesome news! Even just one of the two starting "soon" would be most welcome.

+1 (to CW sieve from a purely oersonal standpoint).


Yeah, everyone wants to see old projects reopened to get that next badge, or to be able to get a badge that closed before you started. I have no doubt that restarting any suspended project will be very popular.

To use a greek expression, from your mouth and to god's ear! :-)
