SMP Guide

SiriusB · 12 Mar 2007 at 12:08

Ahh welcome back and I am glad you like the guide.

Well, first of all your problem comes from not reading the errata at the end of my first post - it has all the mistakes people have spotted so far!

When you run ./finstall you need to add the smp flag. So you need to enter:

Code:

./finstall smp

As for the questions yes I admit I forgot about some of them - it was a long night

Anyway, the answers I put are no to the FAQ and yes to the MD5. The MachineID one shouldn't come up at all if you use the SMP flag.

I couldn't get much done to the guide over the weekend partly due to being busy with stuff and partly because I was having fun and games with getting Wifi to work on my laptop in Ubuntu

[That was after the main event of getting Ubuntu ON my laptop in the first place!]

Anyway, since the mistakes are starting to affect people I will get on it right away and update the hosted files. I would give it a few hours before seeing the changes as I have other things to do today.

mikeymike · 12 Mar 2007 at 12:19

Ahh thanks, i was reading the errata but i didn't understand what part that error referred to. I shall try it again now.

On a side note, I'm reading the openoffice version currently, and there's 2 copies of what to paste into the sources list when setting up ubuntu initially, not sure if thats an error but im guessing it is.

**EDIT**

Ok that worked, the smp flag was true and it didn't ask me the question about setting up machineID's, but then after that, again it went to the guide about setting up F@H then back to prompt, i didn't get the config questions, am i still missing something out here?

Here is a copy of the terminal:

Code:

[B]michael@michael-linux:~$ ./finstall smp[/B]

 This is FAH ("Folding At Home") installation script (ver. 5.3).

You can start the FAH client(s) by running
'/home/michael/foldingathome/folding start'
or start ./FaH scripts directly inside CPU directories.

Note: If You would like to set some FAH flags, take a look inside ./FaH and/or
read the finstall documentation.

There are couple of ways how to run FAH client(s) at system bootup as a service:
a) You should copy
/home/michael/foldingathome/folding to your system
service directory (ie: /etc/init.d/ (*)) and then start it
with '/etc/init.d/folding start'.
Also, You may have to run 'chkconfig --add folding' (**).

  (*) Your distribution may not support this kind of service startup
  or you may have one of those cases (RedHat 8.0) where despite all
  efforts, FAH refuses to start up when it is registered to run as a
  service. To overcome this issue, add '/etc/init.d/folding start'
  to /etc/rc.d/rc.local or another startup script that your system
  or distribution uses (Mandrake - rc.boot, SuSe - boot.local, ...)
  You may also need to remove 'folding' from runnable services by
  disabling it (setup->System services) or by running
  'chkconfig --del folding' if needed.

  (**) There is no 'chkconfig' on Debian, use 'update-rc.d folding defaults' 
  to add 'folding' services and 'update-rc.d folding remove' to remove
  'folding' services.
  
Note: MacOSX does not have "/etc/init.d" service startup method, use
Crontab or StartupItems to get the FAH client(s) going.

b) Another way to start FAH as a service is to use "crontab":
http://teammacosx.homeunix.com/forum/cgi-bin/ikonboard.pl?s=630986ed363be3092a87
37a56af58b87;act=ST;f=10;t=173

Short "crontab" howto:

Start "crontab -e", press "i", 
add "@reboot /home/michael/foldingathome/folding start >/dev/null" 
to the end of file, press [Esc] key, type ":x" and press [Enter].

Note: Only root user can modify system services (normal users have crontab optio
n).
Let root user to run
/home/michael/foldingathome/installService
to install FAH to be runned as service at system startup.
  
Note1: FAH client(s) will be started under user michael's privileges.
Note2: If you try to start FAH client(s) as different user, you will be
prompted for user michael's password.

The yellow box with what needs to be pasted into the file goes over two pages, so it would appear that there are two yellow boxes. Just paste the contents of the first box into the file then the second box immediately below.

As for your SMP weirdness I am not sure. It may have already found a config file from your first finstall installation. Your best bet is to go into your home folder and completely nuke any Folding-related folders. You should be able to do this from the GUI.

From the Terminal:

Code:

cd ~
ls #lists all the files and folders in your home directory.  Make a note of any folding@home folders

sudo rm -rf [b][I]nameoffolder[/I][/b]  #do this for each folder#

This will permanently delete those folders and all their contents.

Once done go back to your Terminal, change to the folder where your finstall script is located and run

Code:

./finstall smp

again.

BillytheImpaler · 12 Mar 2007 at 12:50

EDIT: Sirius is more right than I was.

Nuke any client.cfg files and give it another go. Heck, you could nuke any files in your foldingathome directory except for finstall itself.

Berserker · 12 Mar 2007 at 12:56

apt-get blew up (loads of download errors and stuff about corrupt files) when I tried with the stuff in the big yellow box. I went back to the backup and it was fine, so I didn't bother after that - just got on with the next steps.

Might be because I installed the server version of Ubuntu. All the funky graphics just steal valuable cycles from folding, which is obviously not what I wanted. In fact, I configured the ssh service and set VMWare to run headless, then turned all the graphics off on the host box too.

Looking forward to SMP on 32-bit Linux though. Might be more borging potential with that.

SiriusB · 12 Mar 2007 at 13:03

I think I shall move that yellow box onto a page of its own as it seems to be causing some people a bit of aggro!

This wont be a problem on the web page when I get around to doing it. I love making plans for the weekend. They never happen lol.

Berserker · 12 Mar 2007 at 13:35

How about moving that info into a seperate file and giving instructions to wget it. Should be much safer.

mikeymike · 12 Mar 2007 at 13:38

All files deleted, i even went back and re-downloaded finstall, still same error, i think it is this part in the code where it all goes pearshaped:

Code:

Configuring FAH client in directory /home/michael/foldingathome/CPU1:

Is there just a way i can add whatever needs to be in this file? ive tried going to the directory and using
./FaH -configonly
but it tells me this:

Code:

michael@michael-linux:~$ cd /home/michael/foldingathome/CPU1
michael@michael-linux:~/foldingathome/CPU1$ ./FaH -configonly

Starting FAH...

./FaH: line 75: /home/michael/foldingathome/CPU1/fah5: No such file or directory
michael@michael-linux:~/foldingathome/CPU1$ cd /home/michael/foldingathome/CPU1
michael@michael-linux:~/foldingathome/CPU1$

There is a file called fah5 in that directory though?

BillytheImpaler · 12 Mar 2007 at 13:42

That is the actual Folding client executable if I'm not mistaken. Run that, just as you would if it were FAH502.exe on Windows, with the -configonly option.

This will start it in config mode and it'll create a client.cfg. You'd then go back to ~/foldingathome and run ./folding start and see if it works.

mikeymike · 12 Mar 2007 at 13:48

Code:

michael@michael-linux:~/foldingathome/CPU1$ ls
FaH  fah5  FAH504-Console.exe  mpiexec
michael@michael-linux:~/foldingathome/CPU1$ ./fah5 -configonly
bash: ./fah5: No such file or directory
michael@michael-linux:~/foldingathome/CPU1$

if i list files its there, but if i try to use it, it says its not there, something is obv wrong :confused:

Whoops, try
./FAH504-Console.exe -configonly

You can tell I've never a actually run the Linux SMP client. I'm sorta riding on the seat of my trousers.

SiriusB · 12 Mar 2007 at 14:14

Could someone confirm that the link to the finstall script in my guide actually links to a working finstall script?

I would try on my laptop but it wouldn't be an accurate test since it is a lowly cellery and may cause a load of errors on its own.

Although having said all that I am sure a few people have successfully managed with my guide

EDIT: Mike - try doing the manual install of the SMP client. That should work no matter what.

mikeymike · 12 Mar 2007 at 14:23

It defo links to a working version, or the one i used did, up until the point it gave me all that crap anyway

I tried

michael@michael-linux:~/foldingathome/CPU1$ ./FAH504-Console.exe -configonly

and woohoo it worked, loaded my info and i've been carrying on with the guide, but now i've gotten stuck again trying to install fahmon, its saying error trying to download stuff.

On top of that, now F@H has been running a few mins i thought i'd check manually from the log file that its got a WU, but DOH! its got nothing, seems to be stuck connecting to the FAH work server?

This happened to me the first time I installed ubuntu on VMware.. I believe it's because you don't have the 32bit library installed (fah5 is a 32bit program and the 64bit ubuntu doesn't recognise it).
You have to install the library by using the command "sudo apt-get install ia32-libs"

Hope this helps!

Cheers,

Kinnison.

mikeymike · 12 Mar 2007 at 14:36

I'm pretty sure they are installed? If i go to synaptic thingy it says this when i search for them:

SiriusB · 12 Mar 2007 at 14:37

If he followed the guide then he should have installed the ia32libs.

As for not getting any WUs from the server.. that is Stanford's fault - not the guide!

EDIT: Can you access the Internet from within Ubuntu? Open up Firefox and see if you can surf the net. If not then we have found the problem.

mikeymike · 12 Mar 2007 at 14:43

yes i can get on the net

else i wouldn't have managed to Download anything, plus im viewing this forum through ubuntu right now

The log has added one new line since i started the client at 10 past;

should i just leave it for half an hour and see if it has done anything? Im downloading the packages for fahmon through that synaptic thing at the moment, as sudo apt-get keeps saying failed.

mikeymike · 12 Mar 2007 at 14:58

I just followed the guide bit for compiling fahmon from the /FahMon/src directory, it all compiled fine, but it compiled it INTO the /FahMon/src directory, not into /FahMon. So then when the guide says go back one folder and run it, it doesn't work because the actual fahmon executable is sitting in the src directory still. It runs fine if i go back to the src directory and run it though.
Assuming I followed the guide letter for letter, which im pretty sure i did, either the line of code in the guide wants changing so it points it to be compiled into the FahMon directory instead of the src directory, else just change the line in the guide that tells you to run it from /FahMon directory to say run it from /FahMon/src dir.

SiriusB · 12 Mar 2007 at 15:30

See number 4 of the errata

All but a few of the changes have been made. The new guide will be uploaded later this evening, I am having some issues with my web hosting's control panel.

mikeymike · 12 Mar 2007 at 15:35

Ah right

ok well in the mean-time, i did a manual install, and its downloaded a core straight away

I therefore cannot say that that finstall install actually works, it didn't seem to for me, if anyone else has followed the guide maybe it will have worked for them.

Too many problems for me though, especially when manual install is probably quicker To be honest .

You have to say yes/no less times, and you don't have to wait while you DL a load of crap like manuals you aren't going to read with the finstall version.
