Abstract: An artificial intelligence, AI, planning controller control the timing of when a plan (16) to accomplish a task (14) is synthesized. The AI planning controller in this regard determines a quiescent phase (20) during which values of at least some predicates describing a state of the system (12) will remain stable. The AI planning controller then controls artificial intelligence planning to synthesize the plan (16) during at least some of the quiescent phase (20).

Abstract: There is provided mechanisms for initiating writing data of a pending memory write on a host computer. A method comprises monitoring pending memory writes for a non-volatile memory write indicator (NVMWI). The NVMWI is either set or not set. The method comprises initiating writing of the data of the pending memory write. Writing of the data is initiated to both a non-volatile memory (NVM) and a volatile memory (VM) when the NVMWI for the pending memory write is set. Writing of the data otherwise is initiated only to the VM.

Abstract: A method performed by a coordinating entity in a disaggregated data center architecture wherein computing resources are separated in discrete resource pools and associated together to represent a functional server. The coordinating entity obtains a setup of processor cores that are coupled logically as the functional server, and determines an index indicating an identity of a cache coherency domain based on the obtained setup of processor cores. The coordinating entity further configures one or more communicating entities associated with the obtained setup of processor cores, to use the determined index when handling updated cache related data.

Abstract: A method and a supporting node (150) for supporting a process scheduling node (110) when scheduling a process to a first execution node (130) of a cluster (120) of execution nodes (130, 140, 150) are disclosed. The supporting node (150) receives (A140), from the first execution node (130) being selected by the process scheduling node (110) for execution of the process, a request for allocation of one or more HA devices (131, 141, 151). The supporting node (150) allocates at least one HA device (141), being associated with a second execution node (140) of the cluster (120), to the first execution node (130). The supporting node (150) reduces a value representing number of HA devices (131, 141, 151) available for allocation to the first execution node (130) while taking said at least one HA device (141) into account. The supporting node (150) sends the value to the first execution node (130).

Abstract: A method and a resource scheduler for enabling a computing unit to use memory resources in a remote memory pool. The resource scheduler allocates a memory unit in the remote memory pool to the computing unit for usage of memory resources in the allocated memory unit, and assigns an optical wavelength for communication between the computing unit and the allocated memory unit over an optical network. The resource scheduler further configures at least the computing unit with a first mapping between the assigned optical wavelength and the allocated memory unit. Thereby, the optical network can be utilized efficiently to achieve rapid and reliable communication of messages from the computing unit to the allocated memory unit.

Abstract: A method and network interface card providing central processor unit efficient storing of data. The NIC receives request for registering a memory address range in the NIC, the request comprising a rewrite protection granularity for the memory address range. When receiving data from a client process, subsequent to registering of said memory address range, said data having an address within the memory address range, the NIC determines whether the rewrite protection granularity of the NIC is reached, when receiving said data. In the event that the rewrite protection granularity is reached, the NIC inactivates the memory address range according to said reached rewrite protection granularity. The auto-inactivated memory address range also provides a rewrite protection of data when storing data. Remote logging or monitoring of data is also enabled, wherein the logging or monitoring may be regarded to become server-less.
