Good job! Might have closed a side leak there. Next step might be to to make sure certain TCP packets under a certain classification gets encrypted together with data traffic?


Worth mentioning a Haswell system with QDR i helped build. I discovered that it was needed to use an older version of libpsm to avoid a bandwidth boost tweak that increased latency which isn't the competitive advantage of IB QDR. Also highly disappointing they down clocked Haswell as soon as AVX2 was touched. Given no temperature increase, there isn't a thermal argument for it just for using more of the micro instructions on the die. Was an early system, and needed to use end-of-life CentOS for the correct library versions.


So gather-scatter is slightly inaccurate, as it is more detailed memory management.


Although, quite obviously used to accelerate memory access in AVX2. Sorry for adding much after, its 6 years ago.


Actually,it was for auto-vectorization. Given the data structure and algorithm used it wasn't feasible. And ended up proposing gather-scatter scatter-gather in software as though different math involved for different geometries, it is still embarrassingly parallel, but not for single simulated collision events. And it was for GEANT to take advantage of future hardware and increase instructions per clock where memory bandwidth is a problem: http://geant.cern.ch/
