LLRnet servers needed
I just want to post here where I think we will need LLRnet servers now and in the near future:
NPLB: 2 for 400<k<=1001 for n=333.3K600K 1 for 400<k<=1001 for n=260K320K 2 for 300<k<400 for n=333.3K600K in early March (I would like to do the next rally on this one; after the rally 1 server may be sufficient) 1 for 300<k<400 for n=260K333.3K in early March (smaller # of k's and nrange; shouldn't take too long) 1 for 300<k<400 for n=600K1M in late March (will only be the few k's that have already been searched to n=600K) 1 for 300<k<400 for n=100K260K double check CRUS (Conjectures 'R Us): 1 for Riesel base 16 (currently @ n=~430K base 2; data available up to n=800K base 2) 1 for Sierp base 16 (currently @ n=~440K base 2; data available up to n=800K base 2) 1 for Sierp base 6 1 for another base to be determined in the near future 1 for Sierp base 4 for one k for n=1.85M2M base 2, i.e. the minidrive (temporary; shouldn't take long but is a nuisance for a single person to easily knock out due to testing times) Total of 8 servers for NPLB and 5 for CRUS. Later, I would like to add possibly 23 more servers for CRUS when we get testing up past n=200K on several of the bases, especially the lower ones. The best example would be Sierp base 6 where the # of k's remaining will dictate that we probably need 2 servers. This is why I am thinking that we need all the servers that we can get. Note to folks with some or mostly nonconnected machines: Both projects will always have manual reservations available for all efforts. I just pulled all of this off of the cuff, so to speak. Input and opinions are welcome. Gary

I'm hoping to be able to get an older computer set up as an alwayson server sometime soon (i.e. within a month or two), so once I've got that set up, I should be able to run one server. (No more than one, though, since it's only got 128MB of RAM.)

Hmm, let's see how we're doing with each one of those needs:

please keep also in mind that all these servers has to be maintained (in a timelymanner) and evaluated say k/npairs statistics for user and primes!
so for NPLB all resultfiles from the servers goes to me.

As well as to me, too, so I can run the results files through my processing scripts to turn them into regular manualLLRformat lresults.txt files.

You are really crazy Gary!!!
I'll only host max of three servers.

Hey, maybe we can set a world record for most LLRnet servers in one project? Last fiddled with by mdettweiler on 20080225 at 22:00

Well, of course, we must keep in mind that even as we add more servers over time, old ones will be dropping awaysuch as the ones for 260K<n<320K on 400<k<1001, since that range is not far away from being completed.

Yes but for the moment NPLB is still a small project with only a few members. We still don't have such a visibility to have 8 servers running, you will have the same members jumping from server to server...

You do have a point...maybe we should make sure that until we grow significantly, we don't have more than 5 unique servers running at a time (I say "unique servers" since some of the ones listed in Gary's post would be duplicates for load distribution reasons).
