Thanks for all of these comments - I had similar questions.
What is the minimum RAM for a master or a slave? I have heard that the
Mesos slave software adds 1GB of RAM on top of what the slave's workload
processing will require. I have read that 8GB is the min for a Mesos
machine but it wasn't clear that this was an official/hard requirement.
There are probably published/standard numbers for the various distros
that the slave node is build upon (actual or virtual). Actually with a
robust (CI) infrastructure, these sort of resource metrics and the
various benchmarks should be revealed to the user community, routinely.
I'm not certain on what, if any, of this sort of data is being published.
If you tune (stip) the Operating System or the virtual image or the
kernel, then these numbers are most likely lower. I'm not sure much has
been published on "tuning" the OS, kernels or installs for mesos. HPC
offerings will surely be pushing the envelop of these and many more
related metrics for performance tuning to specialized classes of
problem, hardware specifics and other goals of performance tuning.
Most will run on "bloat_ware" but the smarter datacenters and HPC folks
will 'cut the pork' for those single digit performance gains. YMMV.
