چکیده
Abstract In our initial DaMoN paper, we set out the goal to revisit results of “Starring into Abyss [...] Concurrency Control with [1000] Cores” (Yu in Proc. VLDB Endow 8: 209-220, 2014). Against their assumption, today do not see single-socket CPUs 1000 cores. Instead, multi-socket hardware is prevalent and fact offers over Hence, evaluated concurrency control (CC) schemes on a real (Intel-based) platform. To surprise, made interesting findings opposing original analysis that discussed paper. this further broaden analysis, detailing effect workload characteristics via additional platforms (IBM Power8 9) full TPC-C transaction mix. Among others, identified clear connections between performance CC characteristics, especially concerning NUMA CPU cache. Overall, conclude no scheme can efficiently make use large robust manner suggest several directions how overall OLTP DBMS should evolve future.

Scaling Turbo Boost to a 1000 cores
The Intel® CoreTM i7 processor code named Nehalem provides a feature named Turbo Boost which opportunistically varies the frequencies of the processor’s cores. The frequency of a core is determined by core temperature, the number of active cores, the estimated power consumption, the estimated current consumption, and operating system frequency scaling requests. For a chip multi-processor(CMP) t...

متن کاملCreative Tiling: a Story of 1000-and-1 Curves
We describe a procedure that utilizes symmetric curves for building artistic tiles. One particular curve was found to mesh nicely with hundreds other curves, resulting in eye-catching tiling designs. The results of our work serve as a good example of using ideas from 2-D graphics and algorithms in a practical web-based application.
متن کاملMeasurement of Archie Parameters of Some Carbonate Cores at Full Reservoir Conditions (Short Communication)
Application of Archie equation in carbonate reservoirs is not easy due to high dependence of its parameters on carbonate characteristics. Carbonates are very heterogeneous in nature and hydrocarbon reserve estimation in these reservoirs of mostly oil-wet and intermediate-wet is highly influenced by the input values of saturation exponent. To our knowledge, non representative oils have been us...
