We handwrite PTX ;-)
Cost-wise, public cloud destroys traditional supercomputers, and the gap will just keep increasing. However, the economics enabling it, e.g., sufficiently non-interfering multitenancy, are only now reaching the needs of HPC. Likewise, only recently did public clouds embrace non-wimpy hardware: SSDs, multiGPU, starting to have FPGAs, etc. Exposed interconnects are 10 gige, so not the best, but like you said, scale requires designing for minimizing communication to beginwith.
RE:long jobs, we focus on interactive exploration (< 100ms). Spark etc. give up latency to ensure resiliency on long jobs.
