Totally agree. It'd be relatively trivial to automate converting this script into a distributed application. Haven't checked Manta out, but I will. For ultimate performance though right now you could go for something like OpenMP + MPI which gets you scalability/fault-tolerance. In a few months you'll also be able to use something like RaftLib as a dataflow/stream processing API for distributed computation (almost ready to roll out the distributed back-end). MPI though has decades of research in HPC to make it the most robust distributed compute platform in existence (though not the most easy to use). You think your big data problems are big...nah, supercomputers were doing todays big data back in the late 90's. Just a totally different crowd with slightly different solutions. MPI is hard to use, Spark/Storm is much easier...but much slower.
