Juelich Supercomputing Center has a POWER9 system which I was able to experiment with. A lot of interesting differences from 4 way SMT, 128byte cache line size to faster main memory bandwidth and multi GPUs.
In the end, it was great but not magical, so the difficulty of acquiring offsets the benefits IMO.
- cptnapalm 6y agoI have a 1999 IBM Multiprise 3000 and I learned that the processor has a 256-byte cache line which dropped my jaw when I read about that. Sadly, I can't get the Service Element software so I can't actually do anything with it.
