Just wanted to drop you a line to say that we are now using distcc
at work and it is excellent. We have a rack of opteron machines
that we use for computational tasks and we are now using them as a
compile farm to compile our ~1MLOC C++ tree (which can take an hour
on a single CPU to recompile if we change certain header files). We
tried using Sun's grid engine to do this (we already use it to
schedule our computational jobs), but the combination of its polled
operation and the overhead of NFS led to little improvement (and
greatly stressed our network). With distcc compile times are way
down and my productivity has greatly improved; the two best
features for me are its low impact on the network and its
simplicity.
Please let me know how it works for you.
