Because the real world is too messy, maybe I'll use a simplified model of gcc to test my three or four hypotheses about bottlenecks in distcc on shared clusters of workstations. In particular, I'll use something that looks like gcc, but always simply calculates the first million primes or twiddles its thumbs a million times some other way. I won't even bother with preprocessing or linking. Also, I won't use 'make' to drive distcc; I'll just use a shell script. So my 'build script' to simulate building five executables would look like
echo foo > foo.c for i in 0 1 2 3 4; do for j in 0 1 2 3 4 5 6 7; do distcc gcc -c foo.c & done wait done
or something like that. That should be just enough to let me see if distcc has the issues I suspect it does. - Dan
