(102 = 0x66) using sci-biology/foldingathome:Gentoo

[ThunderRd]

OK Joe, fair enough. It's a semantic argument not related to my problem, anyhow.

I'll wait around and see if axs can help out, but maybe he'll suggest that I move this to the bugtracker anyhow, as here might not be the best place to get help.

[axs]

And incidentally, I believe this is a 'supported' install method, according to special permissions issued to the Gentoo project by Pande: viewtopic.php?f=16&t=22524&p=242433&hilit=gentoo+folding#p242020

The content of that thread gives us permission to make folding@home available in Gentoo's package repository, but it's up to Gentoo to pick up any pieces and make sure things work as expected -- Folding@home would need to be the authors of the ebuild in order for it to be "officially supported" by them.

Now back to the issue at hand -- Gento's package is set up to run folding@home as a system daemon, rather than as a specific individual user. Generally on a Gentoo system, if you want to install something like this that will be used just by one user, you would install it into HOME instead of using a system package. That doesn't mean it has to be this way of course, and I'll certainly look into getting it to work properly when run as a user instead of just as a system daemon. In terms of the error itself, I'll try and reproduce it and see if I can help sort it out for you (HOMEdir install or not).

[ThunderRd]

Any suggestions would be great, axs. If I can't run it as a normal user, how is it supposed to be run as a daemon? Should I be starting it from .xinitrc or something like that?

And thank you for taking the time to check in here, it's appreciated. It's nearly 10PM here, so I'll check back tomorrow. Let me know if there is any more information you need about the problem.

[axs]

OK so a bit of information:

Gentoo's package does install folding@home to /opt/foldingathome , as generally /opt is the best location for self-contained prebuilt binaries. That directory and everything in it is installed with ownership of foldingathome:nogroup and 755 permissions (ie world executable). The system's init script launches FAHClient as user foldingathome and with /opt/foldingathome as the current directory.

While trying to reproduce your issue, I couldn't. I successfully ran FAHClient as my own user simply by:
1 - emerge foldingathome
2 - mkdir ${HOME}/randomsubdir && cd ${HOME}/randomsubdir
3 - /opt/foldingathome/FAHClient --configure # since it was an empty dir and I didn't have a config file to use anyhow
4 - /opt/foldingathome/FAHClient

...and FAHClient seems to have had no issues at all starting up, grabbing a dataset to work on, and starting to fold:

....so given that everything seems to work just fine as a new installation and new configuration, I'm going to take a guess that whatever this issue is that you're having has to do with the configuration and/or data files made by the old foldingathome client not being entirely compatible with 7.4.4. Either way, it doesn't seem to be a Gentoo-specific issue.

Where are your foldingathome support files located (config.xml, working directory, etc)? Maybe we can get to the bottom of this by sorting that out. In my specific test case, it seems FAHClient (by default at least) expects to have full rights in whatever the current directory is when you launch it.

Mod edit: changed Quote tags to Code on the log file

[ThunderRd]

Well, I removed all traces of previous install and started over. Created a new config.xml and ran from a home directory location . The client runs as regular user properly without further ownership/permission changes [the owner:group and perms are as you said they would be], but alas produces the same error message as before, the core failing to engage. Incidentally, I rebooted into both a 3.18 and 3.19 kernel with identical results, as well:

I don't know if this matters or not, but I'm running Gentoo stable with a 3.14 series kernel and glibc-2.20, everything built with gcc-4.8.4 and linked with ld.bfd. I'm also using -march=corei7 (for my i7 processor) rather than -march=native, so my code (edit: i mean binaries, not code) might be a bit more generic than an -march=native user.

I noticed FahCore_a4 is a statically-linked 64bit binary built under a 2.6.15 kernel.. Although unlikely (since your 6.x series client worked fine), it's possible that there's some sort of incompatibility between FahCore_a4, FAHCoreWrapper, and the newness of your kernel/libc/toolchain. Debugging this, of course, will likely be rather difficult and potentially reverse-engineeringy which means you'd be breaking the terms of use.

If would really help if someone in the know could inform us what error 102 = 0x66 actually means. If this could be confirmed as a filesystem access error of some sort at least then we would know we're looking in the right direction.

[axs]

Any suggestions would be great, axs. If I can't run it as a normal user, how is it supposed to be run as a daemon? Should I be starting it from .xinitrc or something like that?

The way it's set up in Gentoo is that the daemon is started and stopped via openrc, specifically /etc/init.d/foldingathome -- just add it to your default runlevel and it'll auto-start at boot.

Everything (config.xml included) gets stored in /opt/foldingathome/ , which is also the working directory for FAHClient. The init script takes care of running FAHClient as the 'foldingathome' user and ensuring it's operating within the /opt/foldingathome/ directory. Also FYI (going back to your first post), the 'initfolding' scripts is a gentooism, which simply wraps FAHClient --configure to make sure that it gets run as the right user and within the /opt/foldingathome/ directory.

[ThunderRd]

I've seen no concrete meanings for the 0x66 error either in my searches. Bruce had responded in another old thread that INTERRUPTED was referring to the client being paused in some way, but that's not the case here. I'm guessing it is something like the code 66 listed on ths page in the wiki: http://fahwiki.net/index.php/CoreStatus_codes

I could build a 3.14 kernel with the existing toolchain to try it out, but am not *really* willing to downgrade gcc and rebuild the whole system for a test.

FWIW, my --info:

And yes, I caught the emerge message that says to start the client as a daemon by adding it to the rc default level, so I understand now. Currently, though, all the working files and directories are in ~/FAH7, which is the directory I created after reinstalling the package, and running it from there.

FahCore returned: INTERRUPTED (102 = 0x66) is a normal termination message from a folding core, it just indicates the core received a signal to terminate. As an example, here is an extract from one of my logs from where I paused the folding slot:

Code: Select all

18:28:09:FS00:Shutting core down
18:28:13:WU00:FS00:0xa4:Client no longer detected. Shutting down core.
18:28:13:WU00:FS00:0xa4:
18:28:13:WU00:FS00:0xa4:Folding@home Core Shutdown: CLIENT_DIED
18:28:13:WU00:FS00:FahCore returned: INTERRUPTED (102 = 0x66)

What is abnormal is for the core to be stopped immediately after starting. That could be from an error detected by the FAHCoreWrapper process or somewhere else in the client. The logged error does not indicate the source of the termination signal, just that the core received one. You might find something in the core log file kept in the work directory for the WU, but I am not sure what all gets logged there.

I looked at the log you mentioned and there's nothing of interest there. It terminates after 'Entering M.D.' and says nothing else after that.

FYI - I found a volunteer running a system-wide ~amd64 Gentoo with 4.0 kernel and all that jazz. They had no issues running foldingathome with the reproduction settings I used a few posts back. Whatever the issue is, it seems to be specific to your system somehow. :/

OK, thanks for that. I'll have to keep digging.

Interestingly enough, I revisited this problem after a month and discovered that some kernel .config setting seemed to be the issue. I don't know which setting it is, and I plan to eliminate them one-by one if necessary, but if someone is knowledgeable about which kernel option might be the problem related to the folding client, it would give me a starting point.

Here is a diff of the old, non-working .config and the new, working one:
