摘要： A method, system, and computer program product for implementing a dual-addressable cache is provided. The method includes adding fields for indirect indices to each congruence class provided in a cache directory. The cache directory is indexed by primary addresses. In response to a request for a primary address based upon a known secondary address corresponding to the primary address, the method also includes generating an index for the secondary address, and inserting or updating one of the indirect indices into one of the fields for a congruence class relating to the secondary address. The indirect index is assigned a value of a virtual index corresponding to the primary address. The method further includes searching congruence classes of each of the indirect indices for the secondary address.

摘要： A system and process for enhancing internal radix sorting bin storage efficiency by using linked blocks of contiguous storage space while controlling the number of partially-filled blocks required. The improved internal radix sorting procedure makes it possible to sort large computer files very efficiently without the risk of overflowing allocated storage space. A Most Significant Byte (MSD) radix sorting procedure avoids the collection step required in the LSD radix sorting procedure. The distribution pass is halted whenever a bin is found to contain less than a predetermined threshold number of records and the bin is then sorted immediately using a simple comparison-based sort. At each distribution rank, the system selects and sorts the smallest bins first, thereby quickly releasing storage blocks that may be required during the distribution sort passes for the larger bins. In this radix sorting procedure, the total number of linked storage blocks of size B can never exceed (R/B)+(1-1/B)A, where R is the total number of records to be sorted and A=(M-1) log.sub.M (R/T)+min (T,M)+1, where M=key field digit radix and T=bin size threshold for switching to comparison-based sort completion.

摘要： Processing restrictions of a computing environment are filtered and blocked, in certain circumstances, such that processing continues despite the restrictions. One restriction includes an indication that address translation is prohibited, in response to a buffer miss. When a processing unit of the computing environment is met with this restriction, it performs a comparison of page indices, which indicates whether the address translation can continue. If address translation can continue, the restriction is ignored. The processing unit includes a processor or a pageable entity, as examples.

摘要： A method and apparatus for implementing a combined data/coherency cache for a shared memory multi-processor. The combined data/coherency cache includes a system cache with a number of entries. The method includes building a system cache directory with a number of entries equal to the number of entries of the system cache. The building includes designating a number of sub-entries for each entry which is determined by a number of sub-entries operable for performing system cache coherency functions. The building also includes providing a sub-entry logic designator for each entry, and mapping one of the sub-entries for each entry to the system cache via the sub-entry logic designator.

摘要： An external data record sorting system that adaptively combines elements of both the distribution-based and the comparison-based sort procedures. The internal distribution-based sorting procedure generates sorted record strings that are twice as long on average as the available internal memory storage space. This MSB radix distribution procedure is adaptively optimized to data file characteristics by a predetermined threshold test that halts the distribution pass for a bin containing fewer records than a predetermined threshold number, which are then immediately sorted using a simpler comparison-based sorting procedure. This system also overlaps the input file reads and secondary storage writes between distribution sequences, thereby minimizing the non-overlapping portions of input/output operations and internal processing operations. As sorted records are written to secondary storage and new records are moved from the input file, the new records may be added to the current distributive sort tree, thereby minimizing the total number of strings created. Because new records are moved in from the input file concurrently with the removal of sorted records to the output area, the average output string can be twice the size of internal storage. By minimizing the number of strings that are later merged to complete the sort, overall external sorting procedure time is minimized.
摘要翻译：外部数据记录分类系统，其自适应地组合基于分布和基于比较的分类过程的元素。内部基于分发的排序过程生成平均为可用内部存储器存储空间的两倍长的排序记录字符串。这个MSB基数分布过程通过预定的阈值测试自适应地优化数据文件特性，该预定阈值测试使包含比预定阈值数目更少的记录的分组的分配通过停止，然后使用更简单的基于比较的分类过程立即排序。该系统还与分配序列之间的输入文件读取和次要存储写入重叠，从而最小化输入/输出操作和内部处理操作的非重叠部分。当排序的记录被写入辅助存储器并且新的记录从输入文件移动时，新的记录可以被添加到当前的分发排序树中，从而最小化所创建的字符串的总数。由于新记录从输入文件中同时移入排序的记录到输出区域，所以平均输出字符串可以是内部存储大小的两倍。通过最小化稍后合并以完成排序的字符串的数量，整体外部排序过程时间最小化。
