new to rc5 have a couple quick q's

[NDGeist]

ok so im in the process of attempting to join team anananananandtech, still havnt gotten my own stats page (i'm impatient, its been a day)... hopefully i should be able to get at least 5 machines running it by the end of the week. but my first question is how long should a WU take on my Athlon 700??? currently it seems like i can leave for a while and it does like 2 or 3 units... and this guy yesterday dumped 2 million... sheesh... that is a lot of units... what am i missing here... and how can he had 2 million units when my computer is downloading 24 @ a time
Thanks

You can set it up so that you download hundreds, thousands, tens of thousands, or, dare I say, hundreds of thousands at a time (it takes awhile though ). The guy(s) who dump more than a couple thousand blocks are garunteed to be running it on more than one computer, or saved up a lot of blocks before "flushing." Often times, it is both. You can (and we encourage you to) run this on as many computers as you can...IF YOU HAVE PERMISSION! .

In the folder in which you installed RC5, you should have a .ini file named "dnetc". In this file, you should see lines that look something like the following:

[rc5]
fetch-workunit-threshold=512
preferred-blocksize=33

What that means is that I have my computer set up to fetch and flush every time it finishes 32 WU's, and that the size I request (though won't always find) is 2^33 keys (or, 32 WU - same thing).

The higher block sizes are preferred, because it means fewer transfers have to be made, and log files are kept smaller (a VERY good thing).

Hope that helps....

If doing nothing else, the Athlon 700 does about 2.45M Keys/s or about 800 blocks a day. A "block" is the same as a "Work Unit". Blocks are contained inside of "Packets", and a packet can hold anywhere from 1 to 32 blocks.

So, if you're crunching a packet that has 32 blocks, it'll take a lot longer then on that has only a single block.

If you are taking inordinately long to complete work, you may be doing OGR stubs, rather then RC5 blocks. The client does both, and will do OGR first.

do i want it doing stubs or blocks??? and a block=a workunit??? so if im doing 3 w/u's a day thats only 3 blocks... at that rate i would have to have hundreds of thousands of computers to set this up on... ???
im completely lost... bigger blocks are better than smaller blocks.... isnt the goal do do a whole lot of small blocks so that your numbers go up??? im really really lost now...

thanks for the help

also, w/ permission from my mis manager, will this program run on NT4 when im at the login screen? i have to log off at the end of the night and dont want all these computers going to waste...

stubs == OGR (Optimal Golumb Ruler - helpful in stuff like telescope spacing, etc). RC5 == WU or Blocks (or, as russ said, packets). RC5 is an encryption algorithm....do whichever one you seem to like best

if you install it as a service it will run even when no user is logged in.

 

[BurntKooshie]

In order to get it to run while at the login screen, it must be installed as a service. Go to a dos prompt, and type "dnetc.exe -install", and this will install it as a service (but you won't see the cute ow in the tray this way). It should be invisible to Task Manager as well.

how will it know to flush and recieve and so on...

NDGeist, you've been doing OGR. Here's your own stats page. Welcome to TA!

 

[NDGeist]

how do i specify what to use.... i still wonder why anyone would do ogr's instead of WU's, they take longer right? and the bigger the # the higher the rating... so wouldnt it make more sense to do Wu's?
Thanks again

OGR stubs are bigger, therefore they take longer. Each one maybe 50 to 250 Gnodes on average. The bigger they are, the longer they take. Your Athlon may do 500Gnodes a day, but they may be 1 WU or 10WUs. The WUs aren't counted just the Gnodes.
1 RC5 block are 2^28 keys and will take about 2mins on an Athlon700. As Russ said, each WU consists of between 1 & 32 blocks per WU. The stats are based on number of blocks done.

If you want to do RC5 then change your dnetc.ini to this:
[misc]
project-priority=DES,CSC,RC5,OGR=0

This tells the client not to do any OGR, just RC5. If you want to do OGR put the =0 after RC5

Athlons are best suited to doing RC5 work.

Oh & welcome to the TeAm NDGeist

Welcome to Team Anandtech, NDGeist!

OGR is a different distributed project that the distributed.net folks sponsor, RC5 is one that the distributed.net folks run as well. Most are doing RC5, but the dnet client defaults to running OGR, so we have to reset the priorities.

Team Anandtech is competing in a number of different projects, and doing dasm good in all of them. OGR, RC5, SETI, Folding@Home, GNOME, UD, to name a few.
