I need smp help

[Mustanley]

Trying to get smp running in native debain. Had been running the regular client without problems. Finished off the last two WUs with the -oneunit flag and installed the smp client.

The machine is a dual opteron (2 x single core opteron 246s) w/ 2gb of ram and the kernel is 2.6. Here's a sample from the log file showing the error I'm getting:

tia everybody

[dz_jad]

EDIT, Looks like you did get the core, I have no clue! My personal troubleshooting would include scrapping the whole FAH SMP directory and re-installing......

[Mustanley]

tried reinstalling in a new directory... still same problem.

[dz_jad]

what's with all of the flags you've got going? I dont run any flags when I go SMP.....not sure if any work besides like -sendall and stuff like that

**Since I dont know much Linux, is this a 64 bit distro? SMP Beta currently needs a 64 bit distro

[Mustanley]

those flags are not required, but the vebosity 9 flag make the log file contain more information and forceasm flag prevents the client from disabling optimization after a crash or EUE.

definitely a 64bit OS.

[dz_jad]

mkay....this is the end of my ability to support! Any you probably already did all of the stuff I said before I mentioned it :p

[Mustanley]

thanks for trying dz_jad :)

[Macaholic]

Just to verify. You were running the Uniprocessor client under Linux and then installed the SMP client for Linux? Are you sure it is pointed to the right folder? If you have the Uniprocessor client folder and the SMP client folder on the same install, it may be getting confused as to which folder to use. I've had a similar thing happen under OS X. Just be sure you are pointed to the correct SMP client folder by checking the ls la in terminal (you should see mpiexec and FahCore_a1.exe in the listing) and perhaps use local to make certain it is using the correct folder.

[Mustanley]

Yes, I was running dual uniprocessor clients first. I installed the smp client to a different directory.

it looks to be using the correct path and I even added the local flag but no luck. same error.

[leelegend]

i have had that a few times....let it do it a few times over and over
eventually mine downloaded a new core and all went fine

lee

[Mustanley]

I've let download a new core probably 10 times by now.

the /work directory has 10 wudata_xx.dat files piled up...:confused: :shrug:

[Hack30]

This is going to sound stupid but are you running a 64bit version of debian?

and if you are make sure you have the 32bit libs installed
the smp client needs these to run

of course make sure your permissions are set correctly


I am not familiar with anything linux besides ubuntu 6.06 6.10 and only limitedly.

Hope this helps

I seem to recall some problem i had similar to this and i can't remember what it was:bang head

[Shelnutt2]

Debian includes the 32bit libraries by default still. Also if it wasn't a 64bit OS he would not be able to run it. The client checks first to make sure its a 64bit OS.

Here is what I would try. 1) Delete everything. 2) Redownload. 3)Run with the -configonly flag. Then run with the -verbosity(9?) flag. And/Or just follow the guide on the FAH SMP FAQ.


Also have you messed with your hosts file at all?

[Macaholic]

of course make sure your permissions are set correctly

Yeah. That is an easy one to forget sometimes, be sure to chmod +x fah5 and mpiexec.

[Mustanley]

permissions are set correctly...

hosts file is pretty much stock aside for one entry for the LAN

the only other entry is for the loopback interface


127.0.0.1 localhost.localdomain localhost

[dz_jad]

:shrug: I hope you figure it out!

[Macaholic]

the only other entry is for the loopback interface

Hmmm. Have a look at the known bug list (http://forum.folding-community.org/ftopic16928.html) for the SMP client. Have you tried pinging yourself? Look at the last bug on the list;

22) There are potential errors if you've chosen a hostname for your computer which also exists on the internet. If your machine is called "MyComputer" and a ping MyComputer gives you any appreciable time delay, change your computer's hostname.

Any other unusual network configurations or considerations?

[Mustanley]

I tried changing the hostname to something that was ping-able but it didn't make a difference.

Not sure what network settings might be breaking the smp client. This machine serves two web site domains, is a mail server and dns server.

nothing else else on the known bug list seems applicable.
