19 # modified to support multiple architectures for toolchain
20 # testing. DMUCS sends the CPU load to a server, which we can query
21 # using the 'gethost' command to get the next available slave for a
22 # remote test based on which one is the least busy. The code for this
23 # enhanced DMUCS is at: http://git.linaro.org/git/toolchain/dmucs.git
