    • A computer system is equipped with an operating system having a tracer driver for generating trace data including disk locations accessed for disk accesses made by various components of the operating system during system startup/boot time. The tracer driver is loaded at an initial phase of system start-up. The computer system is further equipped with a companion disk block relocation driver for generating, if possible, an alternative disk block allocation for a current disk block allocation that will yield improved overall access time for a sequence of disk accesses. In some embodiments, the disk block relocation driver includes logic for tracing the sequence of disk accesses to determine the current disk block allocation, logic for generating the alternative disk block allocation, if possible, using the trace results, and logic for effectuating the alternate disk block allocation, if generated. In one particular embodiment, the logic for generating the alternative disk block allocation employs a random search approach, while in another embodiment, the logic for generating the alternative disk block allocation employs a heuristic approach.
    • 计算机系统配备有具有跟踪器驱动器的操作系统,用于产生跟踪数据,包括在系统启动/启动时间期间由操作系统的各种组件进行的磁盘访问访问的磁盘位置。 示踪器驱动程序在系统启动的初始阶段加载。 计算机系统还配备有配套的磁盘块重定位驱动器,用于如果可能的话,为当前磁盘块分配生成替代的磁盘块分配,这将为一系列磁盘访问产生改进的总体访问时间。 在一些实施例中,磁盘块重定位驱动器包括用于跟踪磁盘访问序列以确定当前磁盘块分配的逻辑,如果可能,使用跟踪结果生成备用磁盘块分配的逻辑,以及用于实现备用磁盘的逻辑 块分配,如果生成。 在一个特定实施例中,用于产生替代磁盘块分配的逻辑采用随机搜索方法,而在另一实施例中,用于生成替代磁盘块分配的逻辑采用启发式方法。

    • A computer system is programmed with a plurality of programming instructions for implementing a software function, having an installation utility with logic for generating, if possible, an alternative disk block allocation for a current disk block allocation that will yield improved overall access time for a sequence of disk accesses. In some embodiments, the logic includes logic for tracing the sequence of disk accesses to determine the current disk block allocation, logic for generating the alternative disk block allocation, if possible, using the trace results, and logic for effectuating the alternate disk block allocation, if generated. In one particular embodiment, the logic for generating the alternative disk block allocation employs a random search approach, while in another embodiment, the logic for generating the alternative disk block allocation employs a heuristic approach.
