To integrate with the Firmament build flow, we'll need to build Flowlessly using clang++.
Currently, this fails:
malte@eucleia:~/Projects/firmament/ext/flowlessly-git(git)$ make

reference>')
handles[num_nodes];

make: *** [utils.o] Error 1
This does not appear to be a trivial fix: the handles
array is an array of boost::binomial_heap handle types. Maybe what we should do here is define a vector?
Will look at a patch later, but ideas welcome.
Per the paper: Firmament: Fast, Centralized Cluster Scheduling at Scale
, Relaxation
and Cost scaling
algorithms performs better than Cycle canceling
and Successive shortest path
algorithms. I just can't find Relaxation
and Cost scaling
in the solver. So, I am wondering why they are not supported in this project?
