Talking LLRnet server rally 400<k<1001 August 8-10

Hi all,

It's time for another LLRnet rally! This one will run for 48 hours, from 7 PM GMT on Friday, August 8, to 7 PM GMT on Sunday, August 10, on our 400<k<1001 servers (though results from 300<k<400 servers will also be counted, as before).

Here's a list of all currently running 400<k<=1001 servers:
-------------------------------------------
server = "nplb.rieselprime.org"
port = 300
-------------
server = "nplb.ironbits.net"
port = 400
-------------
server = "nplb.dynip.telepac.pt"
port = 443
-------------
server = "samband.mine.nu"
port = 6 (somewhat full)
-------------------------------------------

Edit (8/10): This rally is now concluded. Thanks to all who particpated!

General info. on setting up a connection to an LLRnet server can be found here. The above info. should be put in the llr-clientconfig.txt file.

Last rally we kept track ahead of time of who was bringing how many machines to which servers, and that turned out to be quite helpful in terms of knowing which servers were close to their limit (and thus avoiding any painful server freezes). I'd like to request that all you do this again, if possible. Please simply state how many machines you're bringing, and to which servers, and I'll mark it down in the following table as we go.

Code:
User           Cores              Range preference   Server
-----------------------------------------------------------
Anonymous      2 fast             400<k<=1001        C443 (1) IB400 (1)
gd_barnes      24 fast, 4 slower  400<k<=1001        IB400
Flatlander     4 fast             400<k<=1001        AES300
Lennart        68 fast            400<k<=1001        L6
Mini-Geek      2 slower           400<k<=1001        AES300
(misc)         3-4 fast           400<k<=1001        AES300
(misc)         1-2 fast           300<k<400          IB5000
----------------------
Total on AES300: 7-8 fast, 2 slower
Total on C443:   1 fast
Total on IB400:  25 fast, 4 slower
Total on L6:     68 fast
Total on IB5000: 1-2 fast
As for goals...how about we aim to get all servers up to at least n=530K? Ambitious, I know, but hey, better to aim too high than too low in a thing like this.

Have fun and bring on that firepower!

Anon

(@Gary: How about I send an n=2.5K range to each of the C400 and L6 servers? I'm thinking that should be good enough to hold both servers for the duration of the rally, yet without making too much mess for us to clean up after the rally.)

Put me down for two slow cores on nplb.rieselprime.org, unless I need to go to another to help balance it.
I guess my cores are slow...I have 2.5 GHz Athlon and I take about 700 seconds (11 min 40 s) on my numbers at n=530K, 40K FFT (~1.345 ms/iteration).
Maybe I should just say two fast Athlons...

I put your cores down as two "slower" cores since though they may not be Core 2's, they aren't too terribly bad.

Right now, I'm planning on bringing 5 quads plus 2 slower cores.

I'm not sure what ports I'll put them on. I was planning on splitting them between ports 300 and 400 but will determine that what I see what others are bringing.

Would it be too much trouble to count my manual reservation as part of the rally?
I could copy the lresults at the starting time of the rally, then again at the ending time of the rally. I could use scheduled tasks to make it do it precisely at the times. I can send you the difference of the beginning and end files.
My reservation is 530.0-530.6, 400<k<1001. If I could keep doing my manual reservations instead of switching to LLRnet for the rally, it could speed up my reservation by 2 days, plus I won't lose the few % that LLR gets over LLRnet, or have to worry about server or internet problems.

Hmm...well, it might work. After the rally, you could then just send the rally part of your lresults to me, and I could code up a quick Perl script to add lines that say "user=Mini-Geek" and "date=something during the rally" (it wouldn't matter exactly what dates they were, as long as they're somewhere in the rally timeframe, and preferably somewhere closer to the middle so as to not mess up start/end stats). Then I could send the results file (now in LLRnet format) to Karsten, and he can mix it in the bag with all the other rally results.

Gary and Karsten, what are your opinions on this?

Here's my opinion: that's ridiculous .

only my opinion:

to make a range/pairs manually and count them for the ralley is against the 'spirit' of the ralley itself!
the purpose of a ralley is to compete against under the same conditions for all:
so originally there should a workspace=1 (no bigger reservations before/while/after ralley), same llrnetclient for all, no personal server for one, etc...

perhaps there're other opinions.

Karsten

Yeah, I know, I agree that it is a bit convoluted. However, based on some shaky experiences I've had lately with my own internet connection, I fully understand Mini-Geek's desire to have an offline solution. So, if Gary and Karsten are OK with it, we may as well go ahead with it, though I should probably warn everybody that we won't necessarily do this for everybody, or else it will get really hairy.

Ah, Karsten beat me to the punch. One thing, though: could you please clarify that you mean by "workspace=1"?
