Made an account just to write this post. While everyone are right to be proud of this supercomputer(me included) there's few problems that I hope it gets addressed in the future.
1. inadequate memory: Tianhe-2 have 88GB or RAM per node at just over two TFLOP/s while the sunway have only 32GB per node that runs at 3TFLOP/s.
2. Memory isn't particularly fast either at 136.5GB/s which could be a issues since the CPU already lacks on board cache.
3. There also a mention of inefficient interconnect, didn't dig too much into that so I won't comment.
The above problem resulted in a pretty abysmal HPCG benchmark of 0.371PFLOP/s compared to Tianhe-2's 0.580PFLOP/s.
Don't flame me for pointing out the negatives, always look forward to what my home country can come up with next
