Abstract: Embodiments for providing enhanced location-aware protection of latches in a computing environment are provided. One or more latches are combined in one or more of a plurality of bounding boxes on a two-dimensional circuit design layout based on one or more rules. A location-aware interleaving of error correction codes (“ECC”) and burst error correction codes may be selectively applied to one or more latches in those of the plurality of bounding boxes, where multiple bit errors are corrected.

Abstract: A first type memory and a second type memory may be identified in a computing system. The second type memory is slower than the first type memory while having a greater storage capacity compared to the first type memory. An application process executing in the computing system may be identified. A region of the first type memory may be provided as a cache of the second type memory for the application process.

Abstract: Data may be transferred from a volatile memory to a non-volatile memory using a persistent power enabled on-chip data processor upon detecting a power loss from a primary power source. The one or more emergency power supplies are attached to the volatile memory, the non-volatile memory, and the persistent power enabled on-chip data processor to assist with the transferring of data.

Abstract: Various embodiments are provided herein for clearing memory of system in a computing environment. A zero-filled cache line with a single z-bit per entry in the cache directory may be defined. The “z” is a positive integer. A plurality of instruction set architecture (“ISA”) instructions are provided with a single z-bit in a cache line as defined in a cache directory to clear an entire cache line.

Abstract: A multi-purpose server cache directory in a computing environment is provided. One of a plurality of operation modes may be selectively enabled or disabled, by a cache directory, based on a computation phase, data type, and data pattern for caching data in a cache having a plurality of address tags in the cache directory greater than a number of data lines in a cache array.

Abstract: Techniques disclosed herein generally describe providing fault tolerance in a virtual machine cluster using hardware transactional memory. According to one embodiment, a micro-checkpointing tool suspends execution of a virtual machine instance on a primary server. The micro-checkpointing tool identifies one or more memory pages associated with the virtual machine instance that were modified since a previous synchronization. The micro-checkpointing tool maps a first task to an operation to be performed on a memory of the primary server, where the first task is to resume the virtual machine instance. The micro-checkpointing tool also maps a second task to an operation to be performed on the memory of the primary server, where the second task is to copy the identified memory pages associated with the virtual machine instance to a secondary server. The first and second tasks are then performed on the memory.

Abstract: Computation, placement, and accessing of error correcting codes (ECC) in a computer system data cache enabling partial reads and writes to each line of data in the cache. For storing multiple compressed blocks, received at differing time periods, in a single cache line, the ECC for the first compressed block is stored in the ECC field of the cache and the ECC for the second and subsequently received compressed blocks is appended to the compressed data. Additionally, an auxiliary ECC cache may be constructed for temporarily holding a partial ECC for a partial read/write, and a new ECC for the partial read/write is computed using the partial ECC.

Abstract: Compressing data includes hashing a first token length of an incoming data steam into a hash table, where the first token length includes a plurality of bytes. A second token length of the incoming data stream may be hashed into the hash table. The second token may be larger than the first token length and includes the plurality of bytes. The method may further include automatically comparing which token length enabled more efficient data compression, and automatically adjusting at least one of the first and second token lengths based on the comparison.

Abstract translation: 本文公开的技术通常描述了使用硬件事务存储器在虚拟机集群中提供容错。 根据一个实施例，微检查点工具暂停在主服务器上的虚拟机实例的执行。 微检查点工具识别与上一次同步之后修改的与虚拟机实例相关联的一个或多个内存页。 微检查点工具将第一个任务映射到要在主服务器的内存上执行的操作，其中第一个任务将恢复虚拟机实例。 微检查点工具还将第二任务映射到要在主服务器的存储器上执行的操作，其中第二任务是将与虚拟机实例相关联的所识别的存储器页面复制到辅助服务器。 然后在内存上执行第一个和第二个任务。
