摘要： Described are techniques for detecting incompatibilities. A first contents of a data item is determined in accordance with a first set of conventions associated with a first processor architecture. A second contents of said data item is determined in accordance with a second set of conventions associated with a second processor architecture and including at least one convention that is not included in said first set. An actual difference between the first contents and the second contents is determined. It is determined whether the actual difference is expected. If the actual difference is not expected, the data item is flagged as an incompatibility candidate. Code referencing the data item is examined to determine any coding incompatibilities due to coding dependencies.

摘要： In a method for testing computer code, each branch that occurs within the machine-readable code is located. A first tracepoint is placed immediately after the beginning of the branch and a second tracepoint at the target address of each branch, each tracepoint generating an indicator. When the machine-readable code with the tracepoints is executed on the target computer, the method identifies those indicators that have been generated by their corresponding tracepoints, thereby permitting determination of those branches that the program control flow has not passed through. The test cases are modified to exercise the previously omitted branches, and the converted code is re-executed, until all branches have been properly exercised. The tracepoints are automatically eliminated after they have performed their intended function.
摘要翻译：在用于测试计算机代码的方法中，位于机器可读代码内的每个分支都位于该位置。在分支开始之后立即放置第一个跟踪点，并在每个分支的目标地址处放置第二个跟踪点，每个跟踪点生成一个指示符。当在目标计算机上执行具有跟踪点的机器可读代码时，该方法识别由其相应跟踪点生成的那些指示符，从而允许确定程序控制流未通过的那些分支。修改测试用例以执行先前省略的分支，并重新执行转换后的代码，直到所有分支都已正确运行。跟踪点在执行预定功能后自动消除。

摘要： Described are techniques used in connection with cache management. Data included in a cache slot is put “on parole” with a first cache hit while waiting for subsequent cache hits. If a subsequent hit is received to the cache slot, it remains in the cache for a longer time period than a slot having only a first cache hit. The cache may be organized as a plurality of memory banks of cache slots. Each memory bank has an associated control slot that includes groups of extents of tags. Each cache slot has a corresponding tag, and a time stamp. The time stamp of slots in the cache may be adjusted affecting the amount of time a particular portion of data remains in the cache.

摘要： Described are techniques and criteria used in connection with cache management. The cache may be organized as a plurality of memory banks in which each memory bank includes a plurality of slots. Each memory bank has an associated control slot that includes groups of extents of tags. Each cache slot has a corresponding tag that includes a bit value indicating the availability of the associated cache slot, and a time stamp indicating the last time the data in the slot was used. The cache may be shared by multiple processors. Exclusive access of the cache slots is implemented using an atomic compare and swap instruction. The time stamp of slots in the cache may be adjusted to indicate ages of slots affecting the amount of time a particular portion of data remains in the cache. Each director may obtain a cache slot from a private stack of nondata cache slots in addition to accessing a shared cache used by all directors.

摘要： Described are techniques for determining a cache slot. A set of criteria for each of a plurality of families is received. A received data operation associated with a first of said plurality of families is obtained. It is determined, in accordance with the criteria associated with the received data operation, whether to allocate a cache slot in the cache for the received data operation. The criteria for the first family includes a minimum value and a maximum value used in determining a cache partition size range for the first family. The maximum value is used in determining a maximum cache partition size allowable for the first family.

摘要： A method for controlling exclusive access to a resource shared by multiple processors in a data storage system includes providing a system lock procedure to permit a processor to obtain a lock on the shared resource preventing other processors from accessing the shared resource and providing a faked lock procedure to indicate to the system lock procedure that a processor has a lock on the shared resource where such a lock does not exist, and wherein the faked lock procedure prevents another processor from obtaining the lock on the shared resource, but does not prevent other processors from accessing the shared resource. A data storage system according to the invention includes a shared resource, a plurality of processors coupled to the shared resource through a communication channel, and a lock services procedure providing the system lock procedure and the faked lock procedure. In one embodiment, the shared resource is a cache and the system lock procedure permits a processor to lock the entire cache whereas the faked lock procedure is implemented by a processor seeking exclusive access of a cache slot.

摘要： A method and apparatus for cache management in a data storage system is presented. A table with tags corresponding to cache slots in a cache memory is provided. A copy of the table is stored in a local buffer in response to a request for allocation of one of the cache slots. The locally buffered table is used to make the requested cache slot allocation. A set of control parameters associated with the locally buffered table is used to determine if the locally buffered table can be re-used for cache slot allocation in response to a subsequent request for cache slot allocation. User-selectable levels are provided to control the degree of locally buffered table re-use. The user-selectable levels determine which values of the control parameters are used.

摘要： The invention features a method and a system for selecting a slot within a memory unit, e.g., cache, for removal. The memory unit is accessible to a plurality of processors, and each slot in the memory unit has a corresponding entry in an age table. Each time when a processor examines one of the entries, an age value of the entry is increased. When the age value is above a maturity age, the corresponding slot becomes a removable slot. Each processor also maintains statistics to estimate the number of removable slots in the memory unit. According to the statistics, adjusts a maturity age associated with the processor dynamically and independently to control the number of removable slots. Accordingly, the number removable slots can be maintained at a pre-determined percentage relative to the total number of slots in the memory unit.
摘要翻译：本发明的特征在于一种用于选择存储器单元（例如，高速缓存）中的时隙以用于移除的方法和系统。存储器单元可被多个处理器访问，并且存储器单元中的每个时隙在年龄表中具有相应的条目。每当处理器检查其中一个条目时，条目的年龄值将增加。当年龄高于成熟年龄时，相应的插槽将成为可移动插槽。每个处理器还维护统计信息以估计存储器单元中的可移动插槽的数量。根据统计，动态和独立地调整与处理器相关联的成熟期以控制可移动插槽的数量。因此，相对于存储器单元中的时隙总数，可以将数量可移动时隙保持在预定百分比。
