....to simulate the database operations for all the architectures. DBsim is capable of simulating both individual database operations and a sequence of individual operations. It can simulate a wide variety of disks, I O interconnects and processors. DBsim uses the Disksim developed by Ganger et al. [13], for simulating the disk behavior. Disksim is an efficient and accurate disk system simulator. It includes modules for simulating disks, intermediate controllers, buses, device drivers and request schedulers. The sequential scan, indexed scan, sort, group by, ag11 gregate, nested loop join, ....

....contains detailed models for disks, networks and the associated libraries and device drivers; it contains coarse grain models of processors and I O interconnects. For modeling the behavior of disk drives, controllers and device drivers, Howsim uses the Disksim simulator developed by Ganger et al. [16]. Disksim has a detailed disk model that supports zoned disks, spare regions, segmented caches, defect management, prefetch algorithms, bus delays and control overheads. Disksim has been validated against several disk drives using the published disk specifications and SCSI logic analyzers [16] ....

Disksim has been validated against several disk drives using the published disk specifications and SCSI logic analyzers [16]. For modeling I O interconnects, Howsim uses a simple queue based model that has parameters for startup latency, transfer speed and the capacity of the interconnect. For modeling the behavior of networks, message passing libraries and global synchronization operations, Howsim uses the Netsim ....

Disksim has been validated against several disk drives using the published disk specifications and SCSI logic analyzers; it achieves high accuracy the worst case demerit figure [43] for Disksim is only 2. 0 of the corresponding average response time [19]. For modeling I O interconnects, Howsim uses a simple queue based model that has parameters for startup latency, transfer speed and the capacity of the interconnect. For modeling the behavior of user processes, Howsim uses a trace of processing times and I O requests for individual tasks. It ....

....the experiments, we have developed DBsim, an execution driven simulator, which simulates the database operations for both of the architectures. DBsim has detailed models for disks, I O interconnects and processors. To simulate the disk behavior, DBsim uses DiskSim developed by Ganger et al. [19]. DiskSim is an efficient and accurate disk system simulator. It includes modules for simulating disks, intermediate controllers, buses, device drivers, and request schedulers. The demerit figure, as defined in [20] of DiskSim in worst case is only 2.0 of the corresponding average response ....
