Hi Larry

It might be worth us setting up a hardware swaps/donations thread. I've got a P2 400 CPU that you can have, but unless you're in the UK then its probably not economical to post it to you - the same money would probably buy you a 1GHz Celeron plus slot1 tualatin adapter fron ebay that would probably get 4x the work done (as the cache is full speed on the P3s, half speed on the P2s).


Hi DCDC,

It's very kind of you indeed. However, I gave the P2 a go and it did'nt work.

It was worth getting the Windows 98 to get the thing going, but if it won't run Rosetta, then it's too bad, I have other uses I can put the computer to.

Looks like I'll just keep crunching on the P4.

I guess the server would send you work anyway... I might be wrong, but I'd take it the result would just be longer to crunsh, possibly over the deadline, because your computer would have to swap memory all the time.

I might be wrong though, never tried to add a PC with only 64Mb RAM.

- trib'


No Trib' It seems if your memory is < or = 64Mb, Rosetta will not send you work.

I got red messages when I ran BOINC saying work would not be sent.However my computer still shows up as a host.

I don't know why, it used to crunch WU's for Seti@Home without any problems.

LarryM, I finished my tutorial even if it looks ugly.
I'd need a few beta testers to make sure I didn't forget about something crucial before I post it to the general public... Would you like to be one of them?

Anybody else that is interested is welcome, too.
Requisites are: a spare to-be crunshing machine (preferably old crap) with 128Mb RAM, about 1Gb of HDD and a floppy drive. Processor is up to you, my slowest machine is a P2 300Mhz. Oh yeah, and about an hour of your time available. Well... make it two =)

Tribaal,

I got Window 98 setup today on my old Pentium II. It works great, however I made a mistake, it has only 64Mb memory so Rosetta would not send it any work when I run the BOINC Client.

I sure would be interested in Beta testing, but I think I need to install some more memory in this machine!

Otherwise at least I have another backup PC on which I can store software, documents etc.

So I guess I will be staying amognst the "Members with 1 host" for a bit of time yet.

However I thought there were others running Rosetta on Pentium II's with just 64Mb RAM, maybe I am mistaken.

If there are, how did you get Rosetta to send you work?

Thanks again to everybody for helping.

Vester & Trog Dog,

Many thanks for your help and comments.

The Pentium II machine which I was hoping to convert to a dedicated Rosetta Cruncher, is actually a very nice desktop PC which used to do all my Seti@Home crunching very happily. This was with the Old Classic Seti Screensaver.

It is a Siemens Nixdorf 'Xpert' with 300Mhz processor and 650MB Ram.

Therefore it has everything like fans etc. When I bought it, it had a 20GB HD and CD Reader. I then changed the CD Reader to HP 9300 CD Writer and put in a 40GB HD.These components are almost hardly used, so it's a shame not to get some use from them.

I have little doubt that I shall have any problems once Windows 98 is loaded, I then can load my AOL software and connect to the Internet.

Once I do this I am going to set up the BOINC software just to see what it does, and hopefully it will be able to sedately do some extra Rosetta crunching.

Anyhow if it does not run the BOINC software, I still will have another very nice desktop PC which I could use for things like word processing and storing stuff which is on my P4 to release some space on my Hard drive.

As far as the DSL is concerned, well I learnt how to burn a CD from an ISO image, and make a floppy disk from an IMG file, these are things I could not do last week at all, so it has been something of an education tinkering about with the DSL.

I do not have a broadband connection I have ISDN on my main PC, and the Pentium II has a 56k modem. I think it all should run very nicely once I receive my Windows disk which I bought quite legally by the way on eBay.

Anyhow once I get it up and running, I will try BOINC and see what happens.

So watch this space.

...so, if I hear you right, you've got two weeks with which to help a friend get up and running on Rosetta?


I'm also working on that Feet1st, I have asked two friends to start up.

Hopefully they will join.

I don't know if others have noticed but the first thing folks seem to worry about is the security aspects. They think somebody is going to steal their credit card details or something!

It's a tough barrier to get through!

Please, someone just ship this guy their copy of unused win 95/98 that they are no longer using (this way it doesn't violate laws and so forth) ?

I mean, It's 1$ worth of U.S. postage. Make it happen, guys. I've got one copy of 98 and it would violate copyright law to send it to the poor guy.


I have just managed to acquire a copy of Windows 98 SE.

Should be with me in a week or two, so that should now get my new Rosetta Cruncher up and running in a couple of weeks.

Again many thanks for everyone who helped me with this.

I am still looking forward to Tribaal's Tutorial on Linux though, as I would like to try and use Linux as well.

Again thanks to everybody for their very kind help.

I agree, a Memtest would be good to run anyway.

With the setup I suggest to use, you should still have about 128Mb RAM available. My smallest machine has around 124Mbs and works like a charm, but then around 120 Mbs are used by Rosetta.

If you're not sure what memtest is or where to get it, try this link. Basically you create a boot floppy with their program on it, that will try to write bits to every sector of your RAM, and reports any errors.

It's good to have in your toolbox anyway =)

- Trib'


I made a Memtest86 floppy, and am running it on the Pentium II now.

I can get the machine to run Damn Small Linux, but when I go to Net Setup, DSL does,nt even recognise the port where my modem is, so I cannot get it to connect with the Internet.

I should be able in the future to get a Windows 95 system disk, however if I install Windows 95, will BOINC be able to run under this system?

I really don't know enough about computers to be able to use the fdisk in DSL to be able to install it on the hard drive etc.

Anyhow I am starting to regret having switched the damned thing on in the first place, it's really frustrating to have another computer which I just cannot use for anything!

Should have just chucked the thing and forgot about it I feel! :-)

Well I realy am not familliar with DSL at all, but I would take it connecting to your provider shouldn't be too hard... In my set-up, the xDSL router is plugged to computers via regular network cable (rj45), and so the only thing linux needs to know is the network card driver (which is really standard stuff, failure is exceptional).

And even though I don't know how AOL works, I take it plenty of linux users use their network, and so they already found a workaround any problem that may arise =)

I'll keep you updated on the tutorial.

- trib'


Thanks Tribaal, I have spent a whole day trying to get this thing working and just getting nowhere.

I'll wait till your tutorial is posted and then have another go.

Failing that it's start looking for a Windows 95 or 98 Disk from somewhere!

get yourself a copy of Damn Small Linux - I have it running on 4 of my 6 boxes at home. One of these is a 486DX2 16MB (which is just too old to cut the mustard) the others are a celeron 348mHz a celeron 1.7, and a p4 2G. My PII 233 is about to be converted to linux from win98se - I aborted the last wu as I was testing out a new project.


Trog Dog today I downloaded an ISO image of DSL. I then burnt the ISO to a CD to make a bootable CD. However when I tried to boot my computer from the CD it would'nt work.

So Using Rawrite I made a Boot Floppy Disk. Now I can get DSL to run but must always boot from the Floopy and have the CD in the CD reader.

I am lost as to how I can make it that when I turn on my computer, it will boot from my hard drive to automatically load DSL.

I think I need to make a special partition using FDISK or something, I am lost from here on in!

I can only guess too that getting it to connect to my ISP will also be a nightmare, I just ain't a computer expert.

Thanks for the DSL info anyway.

Tribaal,

I for one would be very appreciative indeed if you produced a tutorial on how to get a machine to do Rosetta crunching using Linux.

Trog Dog, I am presently downloading DSL and will see if I can install it on the Pentium II, will update with any success I might have.

It seems that the pay back I will get for crunching for Rosetta, is more knowledge of computing skills.

I think there are lots of people who think that if you have a computer, but do not have the Microsoft software to run it, then the computer is useless. It's nice to learn there are some really knowledgable people on these forums who are so willing to give their time to help others.

I for one would like to say how appreciative I am of this, and look forward to having my dedicated Rosetta Pentium II up and running quite soon.

Thanks again for everybody who is helping me.

Larry

Thanks

I'll put up a short tutorial on "how to set up a machine as a 100% roetta crunsher" using linux (my tutorial will cover installation as well, in case you're unconfident).

I used this technique on several machines already, and it works well for casual crunshing (I know, some make diskless computers and whatnot, but I stick with the stable Debian OS =) )

This tutorial should be online soon, I'll post a link in the forums.

Thanks for all the great advice and ideas.

I think the way to go would be to go the LINUX way.

I really would appreciate a tutorial on how to set up my Pentium II to run Rosetta Crunching under Linux.

I am able to order very cheaply any Linux CD's rather than having to download from the Internet. My only concern is getting the computer to connect with the Internet. I use AOL, and wonder would I be able to connect using Linux?

Thanks again for all the great help and suggestions.

Really all I want to do is to be able to get this machine running and doing something useful rather than just sitting collecting dust and without having to pay Microsoft a fortune.

I am not a computer expert, and hence I am looking advice regarding a Pentium II computer which I own.

This computer used to be my regular PC, until one day I booted it up and the Windows 98 system just kept locking up. Just weeks prior to this I fitted it with a new 20Gb Hard Drive!

Anyhow I bought a Pentium 4 with Windows XP

The old Pentium II has been sitting around gathering dust for three years and today I switched it on (expecting to hear a bang with a blue flash!), and again Windows 98 just locked. So I repartitioned the hard drive and reformatted it.

Now I am left with a working Pentium II computer with only a DOS system on it.

I do not have anyway to load any Windows system onto the computer, since I don't own a Windows 95 or 98 System Disk.

To buy a Windows system disk with which to load Windows 98 would probably cost more than the computer is worth.

Is there any other way I could get this computer running without having to buy Windows?

Primarily I would like it to be able to do Rosetta crunching solely.

Like I say I know enough about computers to keep mine running OK, so I am sorry if my question might seem stupid.

I did read somewhere that BOINC could be run with other systems apart from Windows.

Maybe I should just chuck the thing into a dumpster or donate it to a museum or something instead.

If anyone has any ideas, I would like to know.

If I should jus chuck it say so also!

Thanks in advance.

Post:
Sounds like your hard drive has seen many days of good use. I haven't seen a failure predictor like that before. Perhaps you could post a link to some info? I would have to GUESS that they can't be very accurate. So, maybe a month, maybe a year. If the predictor is based on the MTF (mean time to failure) of the drive, even that has a wide varience I'd think.

I only am running the one computer, and cannot find away to get rid of all the computer ID's.
I read there used to be a merge function, but that it was done away with, so I guess there is no way for me to get rid of all these ID's.


This is one of the things that Rosetta inherits from BOINC. The standard server install that BOINC projects use had a bug with the function to merge hosts together. So, they (Rosetta) just disabled it until BOINC fixes the bug, and then the function will be available again. Your multiple hosts aren't hurting anything. No need to worry about it. When the merge function fix is made, you'll be able to consoladate all of the hosts (and any credits) into one.

However at the end of the day it's more important that the WU's are being done.
HERE HERE!

Thanks again for your help, and I will be staying with the project.
hurray!

Crunch more Rosetta!

Be sure to check out Dr. Baker's Science Journal. He's really doing a great job keeping us informed on progress, and science, and how Rosetta works.



Hi Again Feet1st,

The software regarding the hard drive is found at [url=http://www.drivehealth.com/]

Anyhow it keeps giving me a date for a hard drive failure of between one and two months time. However the price of hard drives have dropped quite a bit in recent years. However I am starting to look at what I need to backup soon just in case.

Anyhow I will keep the puter crunching away anyhow.

When I look at how much credits some users get in a day through using multiple computers it makes my contribution kind of miniscule, however I suppose every little bit helps.

Yes this project seems to be the best for someone actually coming up on the message board and explaining how our help is contributing.

I also get fun looking at the BOINC Stats

Anyhow thanks again for all your help, in the meantime I'll keep floggin this hard drive to death!

Post:
To assure that your BOINC Manager is using the settings you've configured, you'll want to go to the commands pulldown and assure that the "Run based on preferences" is selected. This gives you a quick way to temporarily override those settings directly from your PC, without going through project preferences websites, and updating to the project etc.

I too have been studying my hard drive usage. I'm trying to use the power settings and get the thing to power down, and maybe only write to it every half hour or so. But, mine keeps running too. Never powers down.

What I'm finding is that the cause is:
1) other applications and services running on Windows.
2) page faults, very few of which are caused by Rosetta tasks.

By the way, I'm studying this by looking at the Task Manager of Windows, and then I went in to the VIEW and "select columns" and I added the columns for PF Delta (page faults since last snapshot), I/O Read, I/O Write, I/O Other.

From that, I conclude that if I had more memory, then Rosetta wouldn't be causing page faults. In my case, I've got a dual-core processor, and so two BOINC processes run at the same time, and so even though I have 1.5GB of memory, Rosetta times 2, plus all the other stuff going on is using all of it. I'm even seeing iTunes tasks kick in and generate page faults... and I've not used it since I rebooted my PC.

I even moved all of my BOINC files out to a network drive, and so all the IO happens over the wire... my hard drive still runs constantly. Never powers down.

So, from this, I infer that my hard drive would be running due to page faults from iTunes (and others) regardless of whether Rosetta was running or not. Do you find this to be the case as well?

I see your 4 machines are all 512MB, the recommended minimum. Looks like they are single CPU though, so your's aren't running two at the same time the way mine does. That helps use less memory. (for future readers, if you DO have dual-cores, you might use less memory, and avoid page faults, if you set your general preferences to only use one CPU).

Please avoid sentences like the last of your post. Everyone's going to try to help you out, as soon as they can... with, or without the threat of you leaving. We're just happier to do it, without.

If you still feel you have a specific problem with Rosetta, please provide more information about what you're observing, why you feel it's abnormal, and (if possible) how you feel it might be resolved. That way at least you've contributed some useful information so the project might take steps to avoid upsetting others in your situation in the future.


Thanks for answering my question. Yes I wreckon I owe Rosetta an apology. When I quit BOINC, my hard drive still gets written too quite often, so obviously there are other processes running in the back ground causing the hard drive activity.

Anyhow my Hard Disk Health software is predicting a hard disk failure in about a months time...so...I am donating what life is left in it to the Rosetta project.

Up to the moment I have gotten 13399 hours of use from the hard drive so I suppose it does'nt owe me much.

As to the multi computers...I had to detach from the project a few times when I first started using BOINC two days or so ago, and it gives the odd impression that I am running a computer farm here! I only am running the one computer, and cannot find away to get rid of all the computer ID's.

I read there used to be a merge function, but that it was done away with, so I guess there is no way for me to get rid of all these ID's. However at the end of the day it's more important that the WU's are being done.

Even though I have changed the periods when my hard drive is written too in my preferences, and pressed the "Update" button, nothing seems to change. My hard drive is constantly being written to at perhaps two second intervals.

I have no worries about my CPU being worked at 100% but really do not want my hard drive running continuously.

How else can I get the program to write to my hard drive less frequently?

If I cannot solve this problem soon, I am likely to detach from the project.

18) Message boards : Rosetta@home Science : How can I find out what protein my machine is working on? (Message 13546)
Posted 12 Apr 2006 by LarryM
Post:
Absolutely there is.

First you have to go to the BOINC manager and get the protein's identifier... I currently have a unit called

ALL_TOPOLOGY_CODES_1vcc_434_295_0

The protein's identifier is 1vcc. Then you can go to the Protein Data Bank and enter in the ID (in the search at the top).

You'll then get a page (like this) which has the protein's name, what species it's from, what kind of protein it is (mine's a topoisomerase!!) and which paper published the crystal structure (or NMR structure).

Hope that helps!


Many thanks indeed for your very rapid response.

This is exactly the kind of information I was looking for.

Again thanks my friend and good luck!
