Abstract: Exemplary methods, apparatuses, and systems receive a first request for a storage address at a first access time. Entries are added to first and second data structures. Each entry includes the storage address and the first access time. The first data structure is sorted in an order of storage addresses. The second data structure is sorted in an order of access times. A second request for the storage address is received at a second access time. The first access time is determined by looking up the entry in first data structure using the storage address received in the second request. The entry in the second data structure is looked up using the determined first access time. A number of entries in second data structure that were subsequent to the second entry is determined. A hit count for a reuse distance corresponding to the determined number of entries is incremented.

Abstract: A management server and method for performing resource management operations in a distributed computer system utilizes interference scores for clients executing different workloads to create an interference affinity-type rule for at least some of the clients contending for a resource based on the interference scores for that resource. The interference affinity-type rule can then be used to recommend a target host computer to place a client.

Abstract: A management server and method for performing resource management operations in a distributed computer system utilizes interference scores for clients executing different workloads, including a client to be placed in the distributed computer system, as utilization values of resources, which are assigned continuously variable weights to produce weighted resource utilization values. The weighted resource utilization values are used to generate overall selection scores for host computers of the distributed compute system, which are then used to recommend a target host computer among the host computers of the distributed computer system to place the client.

Abstract: Systems and methods for performing selection of non-uniform memory access (NUMA) nodes for mapping of virtual central processing unit (vCPU) operations to physical processors are provided. A CPU scheduler evaluates the latency between various candidate processors and the memory associated with the vCPU, and the size of the working set of the associated memory, and the vCPU scheduler selects an optimal processor for execution of a vCPU based on the expected memory access latency and the characteristics of the vCPU and the processors. The systems and methods further provide for monitoring system characteristics and rescheduling the vCPUs when other placements provide improved performance and efficiency.

Abstract: Exemplary methods, apparatuses, and systems determine a miss-rate at various amounts of memory allocation for each of a plurality of workloads running within a computer. A value representing an estimated change in miss-rate for each of the workloads based upon an increase in a current allocation of memory to the workload is determined. The workload with a value representing a greatest improvement in hit rate is selected. Additional memory is allocated to the selected workload.

Abstract: A method is described for scheduling in an intelligent manner a plurality of threads on a processor having a plurality of cores and a shared last level cache (LLC). In the method, a first and second scenario having a corresponding first and second combination of threads are identified. The cache occupancies of each of the threads for each of the scenarios are predicted. The predicted cache occupancies being a representation of an amount of the LLC that each of the threads would occupy when running with the other threads on the processor according to the particular scenario. One of the scenarios is identified that results in the least objectionable impacts on all threads, the least objectionable impacts taking into account the impact resulting from the predicted cache occupancies. Finally, a scheduling decision is made according to the one of the scenarios that results in the least objectionable impacts.
