  • Patent number: 10705951
    Abstract: An example system comprises one or more processing nodes to execute one or more processes; a switching fabric coupled to the one or more processing nodes; a fabric-attached memory (FAM) coupled with the switching fabric; and a memory allocator to allocate and release memory in the FAM in response to memory allocation requests and memory release requests from the one or more processes. The memory allocator is to partition the FAM into a memory shelf comprising a plurality of memory books of equal size. The memory allocator is to map a shelf into a virtual memory zone, the zone aligned with the boundaries of one or more books. The memory allocator is to maintain an indexed free-memory list where each index level is an entry point to a list of free memory blocks of a particular size in the zone, and the memory allocator to maintain a bitmap of the zone to identify if a memory block of a particular size is allocated.

  • Patent number: 10691375
    Abstract: In one example, a memory network may control access to a shared memory that is by multiple compute nodes. The memory network may control the access to the shared memory by receiving a memory access request originating from an application executing on the multiple compute nodes and determining a priority for processing the memory access request. The priority determined by the memory network may correspond to a memory address range in the memory that is specifically used by the application.

  • Patent number: 8918496
    Abstract: A method comprises receiving a pattern of resource demands in a workload trace. The method further comprises identifying a plurality of occurrences of the determined pattern in the workload trace, and analyzing the occurrences to determine a trend of the workload trace. The method further comprises generating at least one synthetic workload trace representative of expected resource demands of the received workload trace accounting for the determined trend.

  • Patent number: 8543711
    Abstract: A method comprises receiving, by pattern evaluation logic, a plurality of occurrences of a prospective pattern of resource demands in a representative workload. The method further comprises evaluating, by the pattern evaluation logic, the received occurrences of the prospective pattern of resource demands, and determining, by the pattern evaluation logic, based on the evaluation of the received occurrences of the prospective pattern of resource demands, how representative the prospective pattern is of resource demands of the representative workload.
