 Posted: Tue Feb 03, 2009 11:38 pm Post subject: Project Of The Month For February: SHA-1 Collision Search |
 |
|
Our Project For The Month Of February is SHA-1 Collision Search! This means every KWSN Boinc'er should crunch at least a few work units for that project this month, or even switch over and give the team a boost by crunching full time for this democratically selected research... Here's the link:
http://boinc.iaik.tugraz.at/
What, an .at suffix? Austria? Sounds like we're helping the commies break our crypto codes. Well, if that's what the kanigits want, I'm in! NI!
Here's our team:
http://boinc.iaik.tugraz.at/sha1_coll_search/team_display.php?teamid=45
OK for the record, KWSN is currently in 36th place with 1,039,520 points and 23,238.11 recent average credit...
Get crunching!

I have quite a lot of distance to cover to catch Teammate Dr. V!

OK, I've got 8 AMD/Linux machines in (splitting time with Milkyway until the cache runs out).

Those are some purdy shrubbers, Mike! Looks like they could play a heck of lot of polka music. I'm on the other end of the state in Cincinnati...
Sheesh, I've got about 68 SHA-1 WU's this morning. But looks like they take only about 30 minutes each... |

Ah- Cincinasty. I lived there from 72 to 75 (worked for UC at the time).
I enjoyed it much more than Cleveburg.

I lived Columbus from '94 until about this time last year and worked near Cincy for a couple of those years. It's not a bad place. I'm just outside Washington, DC now. That's been quite a change.
I'm getting everything switched over to SHA-1 and should have all machines running it after a few odds and ends are finished.

Does this mean we table our Aqua challenge? I don't think you can catch up anyway

It looks like this is a Windoze project.
My Q6600/Windows machine (2 cores) is scoring pretty good,
but all the AMD/Linux machines are slow running this.
I may have to boot some of them into Windoze and see if they do any better.
(But I hate to do that because they are also doing a DC-Vault push on ORG & RC5). 
As it is, it looks like they will kick in about 6K/day.

dnetc has a windows client so they could continue to OGR/RC5 push even while using an inferior operating system!

I've thought about it, but I lack licenses for anything "new" to run on the Phenoms, and I've never been brave enough to see if NT Sever 4.0 (which I still have a couple of licenses for) will run on them. I have pretty much refused to buy any new Windoze products except for my "work" machines- I would rather spend the money on HW.

You could do an experiment, toss a copy of ReactOS on one and see if Boinc and/or dnet run on it.

| Now crunching SHA-1 full time... I guess if this helps make Austrian crypto stronger, that's good? |

DANGER- SHA-1 Collision Search.. If you run Linux, check your machines occasionally.
I just found 5 tasks (on 4 different machines) hung @ 0% with no time progress for ? how long.
I had to abort the tasks. The next task in line is running as it should.
????????????

I had a couple of those as well, but it was on the box that's running the sieving. I don't run boinc on it atm due to that, haven't seen any issues on the other boxes. And I've been running SHA on linux for quite a while, this is new. Is your box running other shrubbing at the same time? Or maybe Sha has had a bad bunch of generated jobs...

All the Linux boxes are split with dnetc (1/2 the cores to dnetc, 1/2 to Boinc).
I was wondering if they don't play nice together. As a note, I have not seen this problem with any other projects in the 2 weeks I've been running dnetc.
PS- Just checked this AM, and had to abort 1 task from a Phenom, and 1 from a 5000 X2.
If this continues I may move Boinc to VMs running Windoze.

It looks like it is working. Almost everybody I see on the boards is signing up.
Come on you hold-outs, get in there!
