[distcc] DISTCC on Scyld cluster

[Marcio Teixeira]

Hello,

I solved the path issue. It had to do with the fact that I had different 
compiler paths on my local machine and the cluster, and that our build 
system used an absolute path for the compiler. I had forgotten about 
this snag.

Once I fixed that, the trick of using a wrapper script to cause 
"distccd" to be migrated to a worker node seems to work very well. From 
the external network, it appears as if we only have the head node as a 
worker, but the wrapper makes sure that each daemon runs on a separate 
worker node.

The "beo_distccd" script I ended up using is this:

   #!/bin/sh
   DISTCCD=/opt/scratch/distcc/bin/distccd
   # Currently use only nodes 3 and 4 for testing
   HOST=`beomap --no-local --exclude 
'0:1:2:5:6:7:8:9:10:11:12:13:14:15:16:17:18'`
   bpsh -L $HOST $DISTCCD $*

On my desktop:

   export 
DISTCC_HOSTS=mteixeira at caffeine:/opt/scratch/distcc/bin/beo_distccd
