Abstract: Examples described herein relate to dynamically adjust a manner of identifying hot pages in a remote memory pool based on adjustment of parameters of a data structure. In some examples, the parameters of the data structure include a range of number of access counts and a number of pages associated with the range.

Abstract: Examples described herein relate to circuitry, when operational, configured to: store records of memory accesses to a memory device by at least one requester based on a configuration, wherein the configuration is to specify a duration of memory access capture. In some examples, the at least one requester comprises one or more workloads running on one or more processors. In some examples, the configuration is to specify collection of one or more of: physical address ranges or read or write access type.

Abstract: Examples described herein relate to memory thin provisioning in a memory pool of one or more dual in-line memory modules or memory devices. At any instance, any central processing unit (CPU) can request and receive a full virtual allocation of memory in an amount that exceeds the physical memory attached to the CPU (near memory). A remote pool of additional memory can be dynamically utilized to fill the gap between allocated memory and near memory. This remote pool is shared between multiple CPUs, with dynamic assignment and address re-mapping provided for the remote pool. To improve performance, the near memory can be operated as a cache of the pool memory. Inclusive or exclusive content storage configurations can be applied. An inclusive cache configuration can include an entry in a near memory cache also being stored in a memory pool whereas an exclusive cache configuration can provide an entry in either a near memory cache or in a memory pool but not both. Near memory cache management includes current data location tracking, access counting and other caching heuristics, eviction of data from near memory cache to pool memory and movement of data from pool memory to memory cache.

Abstract: Examples described herein relate to hot page detection. Some examples include circuitry to provide a number of pages with access counts within a bucket of a histogram, wherein the bucket of the histogram is associated with a configured access count range; based on a distribution of access counts in the histogram being a first level, reduce the configured access count ranges of the different buckets of the histogram; determine a second level indicative of page access counts; and migrate data of pages from a far memory to a near memory based on the second level.

Abstract: Examples described herein relate to an apparatus that includes at least two processing units and a memory hub coupled to the at least two processing units. In some examples, the memory hub includes a home agent. In some examples, the memory hub is to perform a memory access request involving a memory device, a first processing unit among the at least two processing units is to send the memory access request to the memory hub. In some examples, the first processing unit is to offload at least some but not all home agent operations to the home agent of the memory hub. In some examples, the first processing unit comprises a second home agent and wherein the second home agent is to perform the at least some but not all home agent operations before the offload of at least some but not all home agent operations to the home agent of the memory hub. In some examples, based on provision of the at least some but not all home agent operations to be performed by the second home agent, the second home agent is to perform the at least some but not all home agent operations.
