A method and a reallocation component for managing a reallocation of information from a source memory sled to a target memory sled. The source and target memory sleds comprise a respective table indicating source status for each page of the source and target memory sleds, respectively. The reallocation component initiates, for each respective source page whose status indicates that the respective source page is initialized, reallocation of the respective content allocated on each respective source page of the source memory sled to a respective target page of the target memory sled. The reallocation component sets for each respective source page whose status indicates that the respective source page is uninitialized, the respective target status for the respective target page to indicate uninitialized, while refraining from reallocating the respective content allocated on each respective source page whose status indicates that the respective source page is uninitialized.

Source and target service nodes and methods are described for transferring a service session for a wireless device from the source node to the target node when a service application is executed in the source node for the wireless device by the service session. In particular, the amount of application data to be transferred from the source node to the target node for a wireless device that is handed over from a first base station to a second base station can be reduced by truncating the application data by an amount corresponding to the data pending in a downlink buffer at the first base station. Thereby, the target node is able to recreate the complete application buffer from the truncated application data and data from the downlink buffer, the latter data being transferred from the first base station () to the second base station (), according to a handover procedure.

Methods and service nodes for transferring a service session for a wireless device between service nodes associated to different base stations

Source and target service nodes and methods are described, for transferring a service session for a wireless device from the source node to the target node when the wireless device is handed over from a first base station associated with the source node to a second base station associated with the target node. A first data amount indication is obtained, which indicates how much downlink data is pending at the first base station. The first base station is requested to delete some or all pending downlink data from a downlink buffer, and the source node transfers to the target node application data and a data amount indication related to a first data amount indication. The target node can then recreate the downlink buffer at the second base station by sending a first part of the application data, corresponding to the second data amount indication, to the second base station.

Migrating an application executing in a source compute sled to a target compute sled. The migration component selects a first sub-set of source pages. A respective source status of each source page of the first sub-set is modified according to a source table. A target table of the target compute sled is set to indicate that a first sub-set of target pages are modified. The migration component migrates the respective content stored in the first sub-set of source pages to target pages and selects a second sub-set of source pages, wherein the respective source status of each source page of the second sub-set is modified according to the source table. The migration component sets the target table to indicate that a second sub-set of target pages is allocated in the memory and then moves the respective content stored in the second sub-set of source pages to the memory.

Methods, computer-readable media, and systems are included for generating information about latency ratings corresponding to a memory pool and a CPU pool. An example method includes for each CPU of the CPU pool, estimating a first latency rating for said each CPU towards the memory pool, and for each memory unit of the memory pool, estimating a second latency rating for said each memory unit towards the CPU pool. The CPUs are organized into a first plurality of groups of CPUs based on the estimated first latency rating, where each CPU of each group of the first plurality of groups has a first common latency rating towards the memory pool. The memory units are organized into a second plurality of groups of memory units based on the estimated second latency rating, where each memory unit of each group of the second plurality of groups has a second common latency rating towards the CPU pool.

Methods and modules relating to allocation of host machines

A method and a defragmentation module for defragmenting resources of a hardware system. The defragmentation module identifies a set of structures. Each structure of the set of structures partially hosts a respective set of host machines. Respective resources of each host machine of the respective set of host machines are allocated in at least two structures of the set of structures. The defragmentation module selects, from the respective resources of a host machine of the respective set of host machine, a remote resource of a first structure being different from a second structure partially hosting the host machine. A remote amount of the remote resource is less than an amount of available resources of the second structure. The defragmentation module assigns the remote amount of the available resources of the second structure to the host machine instead of the remote resource.
