SLOG: serializable, low-latency, geo-replicated transactions Ren et al., The challenge with strict serializability (or even just serializability on a regular DBMS) is that it requires coordination, and as we know, coordination kills performance. That’s where SLOG (Serializable LOw-latency, Geo-replicated transactions) comes in.

The usual caveats also apply: Performance is a deep and nuanced domain, and much can go wrong beyond content size and composition. How sites manage resources after-load can have a big impact on perceived performance. Until and unless teams have better data about their performance, the global baseline budget should be enforced.

Each of the two vector units can issue one FMA instruction per cycle, assuming that there are enough independent accumulators to tolerate the 6-cycle dependent-operation latency.
