## Estimation of availability and reliability in CurveBS CurveBS uses the RAFT protocol to maintain consistency of stored data. It generally takes the form of 3 replicas of data. If one replica fails required to handle the failure according to the actual situation of the system. ## Estimation of availability and reliability in the three-replicas case Assume that the total number of disks in Curve system

# Poster submission: Modern C++ for Parallelism in High Performance Computing Victor Eijkhout CppCon 2024 ## I ntroduction This poster reports on ‘D2D’, a benchmark that explores elegance of expression expression and performance in the context of a High Performance Computing ‘mini-application’. The same code has been implemented using a number of different approaches to parallelism. Implementations are discussed profiling and discussion of performance. By presentation time: So far, exclusively top-of-the-line high core count processors were used. I will compare to a more ordinary desktop, where bandwidth limitations
