Modern database clusters entail two levels of networks: connecting CPUs and NUMA regions inside a single server in the small and multiple servers in the large. The huge performance gap between these two types of networks used to slow down distributed query processing to such an extent that a cluster of machines actually performed worse than a single many-core server. The increased main-memory c...

a high strength nickel chromium alloy (50cr-50ni-nb alloy), commonly referred to as in-657, is specifically used for components in furnaces which are fired by low grade fuel oils containing high levels of vanadium, sodium and sulphur. the purpose of this study is to experimentally investigatethe effect of machining parameters on machinability in turning of inconel 657. the considered parameters...
