Quick grepping on 2010-03 gcc-testresults shows more than 70% of the
results are submitted by only 5 sources:

    106 ghazi
    267 regress at geoffk dot org
    333 Laurent GUERBY
    387 Mike Stein
    905 H.J. Lu

Of these five sources three are running on the GCC compile farm (which
BTW is not limited to GCC testing :). The compile farm operates mostly
out of donated hardware and hosting. We currently cover all non
proprietary OS primary and secondary platforms except s390-linux. 

We're of course open to accept proprietary platforms donations (machine
and/or hosting) provided they come with the right to open public shell
accounts on them (which is the way we operate the project, ~ 160
accounts to date).

Sincerely,

Laurent
