Which version is best for BOINC/Rosetta

Every Linux distro (of the literally hundreds that exist) hast it's pros and cons. If you are a Linux novice I'd suggest to chose one of the mainstream distros (Suse, Fedora, Ubuntu (or astro's Mandrake [EDIT] Mandriva [/EDIT]) to name a few). They usually have a better support and - in case of problems - the community is big enough to help you with all kinds of problems. Once you get familiar with Linux you can choose "more complicated" distros like Gentoo or some BSD flavour (which isn't a good choice regarding BOINC). Alle these are usable with BOINC, but some brand new distros cause problems with some projects (but that's not the distro's fault, it's more or less a kernel problem.)

If Linux/BSD doesn't fit your needs (it doesn't for me, at least as a desktop for everday's use) you may have also a look at OSX. The only "drawback" is that you're bundled to (really nice!) hardware.

Anyone know if it is possible on a dual core computer to have one core running one project, Rosetta, and another core running another, like WCG? I am looking into upgrading to a dual core processor and am curious.

Yes, attach to both projects and assign the same ressource share. Should do the trick

I have to admit that it is tempting to give out the email address of the OEM vice presidents to the R@H community ...

Hehe, would be funny!
But I think it's already enough for them, if you address you complaint on behalf of more than 150.000 participants. This is the worst advertising I can imagine, if I were VP of this company. :)
4) Message boards : Rosetta@home Science : will the data be used for animal testing? (Message 45520)
Posted 27 Aug 2007 by Profile scsimodo
Post:
the reason i ask is that i don't want to be reponsible for the deaths of thousands of innocent animals.

I also don't like animal testing, but what if Rosetta generates some cure for a desease, is there an alternative to animal testing? No, I guess! Or to ask in a provocant way: Are you volunteering to test the new drugs? I guess not, I wouldn't either. So, how should new drugs then be tested if not with animal tests? If you have a serious desease and are already a "death candidate" then you might volunteer in testing. But what if you suffer from - let's say - Parkinson? Are you willing to risk your life to eventually(!!) cure a non-lethal desease?
5) Message boards : Number crunching : PENDING work units (Message 42072)

Post:
Many of my results are listed as PENDING. That's odd! I don't think I've seen that on Rosetta before considering each work unit is crunched only once.

Same here, validator is down

Post:
so he doesn't mind you connecting it up to crunch, but does not want the specifics to be found out? sounds pretty strange to me,unless hes related to uncle sam.

He's afraid someone can get further details (e.g. host name, IP address) if I unhide them. I already explained to him, that nothing interesting can be seen. He still insists on hiding them. His wish is my command :)

I still don't understand why people do this.

Well, if the machines you use don't belong to you and the owner says "hide them", it's better to do that. Especially if the owner is your boss :)
8) Message boards : Number crunching : Claimed/granted credit (Message 39830)
Posted 24 Apr 2007 by Profile scsimodo
Post:
... according to these cross project stats comparing projects on the same machines, Rosetta credit per CPU second is comparable to other projects.

According to my stats Rosetta gives pretty low credits. At least with low-performance CPUs (Duron, Sempron, Athlon XP). Granted credits are about 50 to 80% of the claimed credits. Modern CPUs (P4, A64, X2) give at least equal credits, compared to claimed (in fact it's slightly more). Rosetta claims to not depend on SSE2, but interestingly all SSE2 CPUs perform pretty well, SSE1 CPUs don't. Atleast with my CPUs :)

are they high end machines?

No, average CPUs (Duron, Sempron, P4, AXP). But that's better than nothing, I guess :)

Can't do to much about that can you... :)

No, not really, owner of these machines is my boss :)

But I understand the concern some people have about the privacy of their machine and their life.

You understand people that are concerned about their privacy AND use Windows? Me not! Furthermore, real gamers give a s*** about their privacy, they are only concerned about their fps. Sorry to sound harsh, but that's the truth (at least for me :D)

If i have only one rosetta project going on (i have amd 2700+ prosessor) and i set BOINC to use 100% for crunch....well if i decide to add another project...is my prosessor using then 50% to rosetta and 50% to that other project?.....i mean is it good thing to spread prosessors calculation power?...

sorry, one stupid guy from finland asking stupid questions :D :D


If the ressource share of both projects is equal, every project gets 50% of your crunching time. BUT: Your CPU load will be always at 100%. Boinc crunches project A for 1 hour (depending on your settings) then project B for one hour then again project A and so on. On a single CPU System there's only one project active at a given time. Boinc "switches" between the projects...

No, it's not normal. Maybe it's this problem.

Post:

Looking into your fibril runs right now. Those WUs should be compatible with the new application 5.40 and we have so far had many WUs returned successfully. Has anybody seen the same type of errors on the fibril WUs also?

Just managed it to deliver 1 successful fibril-WU, all others died (5). Bad ratio, if you ask me :) Still one in my queue, let's see how this one behave. I'll let this one run without touching the graphic...

Post:
Something's seriously broken, don't know if it's the client or the WUs. Many DOC-WUs are dying after approx. 1 hour, and those new fibril-WUs don't even think about surviving the first step! Have a look at my results

I turned on the graphics and immediately after switching from "searching backbone" to "search all atoms" the graphics changed and the WU died. Turning on the graphics after the switch to "search all atoms" seem to work fine. Will try this again and keep an eye on it.

[EDIT] Nope, not reproducable! Fourth fibril-WU runs fine even with graphics on[/EDIT]
