No problem.

"ssh tschwinge@84.207.24.48" should now work, do you confirm?

gcc09 is not the most powerful machine, but it is the one
with the most free local disk space, if your project needs
more than 5GB I recommand you use this one.

guerby@gcc01:~$ df -h

Please update the GCC wiki CompileFarm page with a short description of
your project and the cron/machine you plan to use.

Welcome on board :).

PS: I'll be away for 3 hours

[CFARM] Welcome to the GCC Compile Farm

* Rules for participants

1/ Request for administration should be sent to laurent@guerby.net,
that includes missing packages, machines problems, suspicious
activity, etc...

2/ Everything else, proposals and request for general help should go
through gcc@gcc.gnu.org with "[CFARM]" tag in the subject. That includes
adding NFS between machines and how to do it, crontabs you've setup,
where are useful stuff you compiled (binutils, gdb, ...). Don't
forget to update the wiki: http://gcc.gnu.org/wiki/CompileFarm

3/ The machines don't have much RAM (512 MB/processor), so try to choose
one machine that hasn't already a load greater than 2. Please avoid
"-j 2" to leave room for others and easier scheduling.

4/ The machines don't have much disk (some 16GB, some 32GB), so don't
forget to clean up. Disks are not backuped, so please a copy of your
work on your own (hopefully backuped) machine. Machines see each other
/home directory through an NFS mount on /n/0X/. 

5/ Please do not put your real or GCC private keys on the machine, but
feel free to use ssh-keygen to create a specific key for easy use of
ssh within the cluster.

6/ To publish results, just scp them (in compressed form) from your
own machine and send them by email or publish them on your web site.

7/ Laurent Guerby's role is as of last resort on use of the machines,
everyone should try to get consensus on proposals on the GCC list.
The goal is to use 100% of all the CPU all the time and by doing so
improve the GCC development process.
