摘要： A method, apparatus and computer program product are provided for implementing queue pair connection protection over an interconnect network, such as InfiniBand. A message packet is received for a queue pair (QP) and the QP is checked for an imminent connection failure. Responsive to identifying an imminent connection failure, a special message processing mode is established for the QP. After the special message processing mode is established, packets of the message are received without establishing a message queue entry and without storing packet data.

摘要： When a new control thread is initialized in a multi-thread software program, it is determined whether a like control thread has previously been instantiated. If so, a stack offset for the new control thread is set to be staggered from the stack offset for the previously instantiated like thread. By staggering the stack offsets of respective duplicate control threads, cache conflicts may be minimized.

摘要翻译： 当在多线程软件程序中初始化新的控制线程时，确定是否先前已经实例化了类似的控制线程。 如果是这样，新的控制线程的堆栈偏移被设置为从先前实例化的类似线程的堆栈偏移量交错。 通过交错各个重复控制线程的堆栈偏移，缓存冲突可能被最小化。

摘要： A method and computer program product are provided for partial paging and eviction of microprocessor instructions. Responsive to an instruction page fault, a predefined algorithm is applied to a virtual page address for the identified instruction page fault to identify a page table entry group within a volatile memory. Next, searching an identified page table entry group for a free or open page table entry is performed. Responsive to an identified open page table entry, a partial page is copied from a non-volatile memory to a corresponding partial page within the volatile memory. Responsive to failing to identify an open page table entry, a virtual page residing within the volatile memory is selected for eviction based upon at least one of determining which virtual page, of all virtual pages residing in the volatile memory and within the identified page table entry group, has been evicted a fewest number of times; which virtual page has fewest partial pages resident, and which virtual page has been resident longest.

摘要： A method, a system and a computer program product for selecting a primary controller for a server system based on the services offered by each controller. A primary controller designator (PCD) utility determines the relative importance of a controller based upon the services provided by the controller and the weighted importance assigned to these services. The PCD utility classifies the services provided by a system-controller according to the following: (1) the number of OS partitions a system-controller is able to communicate with; and (2) the number of hardware devices that a controller has access to. The importance of the services is determined by the host OS partition information and the degree of importance of a partition that utilizes/requires the particular service(s). The PCD utility designates a controller as a “Primary” if the designated “Primary” is capable of providing services that are required for the most important OS partitions, according to the classification of controller services.

摘要： A method and profiling cache for management of virtual memory includes a set of entries stored in the profiling cache. Each entry of the set of entries includes a page address, a time stamp for the page address and a least recently used (LRU) count; and the LRU count is updated for each access of the page address. Entries in the profiling cache are cast out using the LRU counts. A translation lookaside buffer (TLB) includes a first TLB section for storing a plurality of temporarily pinned entries and a second TLB section for storing a plurality of non-pinned entries. Responsive to a TLB interrupt, an entry is loaded in the second TLB section using a first in first out algorithm for replacing the non-pinned entries. The first TLB portion is periodically updated utilizing identified ones of the set of entries in the profiling cache having oldest time stamps.

摘要： A method, apparatus and computer program product are provided for dynamically minimizing translation lookaside buffer (TLB) entries across contiguous memory. A page table with page table entries (PTEs) is provided for mapping multiple sized pages from a virtual address space to a physical address space. Each of the multiple sized pages is a multiple of a base page size. A region of memory having a starting address and a length is divided into a minimum number of natural blocks for the memory region. Once the region of memory is divided into the natural blocks, page table entries (PTEs) are assigned to map each natural block. Multiple identical PTEs are required to map each natural block greater than a base page size. Only one TLB entry is used to map each natural block.

摘要： In a physical memory space, a pinned memory region is defined at one end of the space and a non-pinned region is defined at the other end of the space. A free region is between the pinned and non-pinned regions. Requests for pinned memory allocations are satisfied either by using holes in the pinned region or by appending the requested block to the end of the pinned region in the free region. The free region may be widened to accommodate pinned memory allocations. Requests for non-pinned memory allocations are satisfied by holes in the non-pinned region, by being appended to the non-pinned region in the free region or by filling holes in the pinned region, in that order.
