  • Publication number: 20220094646
    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.

  • Publication number: 20210173712
    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).

  • Publication number: 20210165690
    Abstract: In a M2M device management system, a Task Orchestration Module, TOM (32) external to the M2M device (20) manages the execution of tasks wholly or partly on the M2M device (20). This alleviates the M2M device (20) of the need to store code, execute tasks, monitor task execution, and the like. The tasks are specified using Finite State Machine, FSM, syntax. A task URL, tURL (34) resource on the M2M device (20) provides a tURL (34) to a resource hosting (36) a service (38) mapping task-IDs to FSM specifications. Communications between the TOM (32) and M2M device (20) is compactly and efficiently achieved using a device management protocol server/client system (16, 18), such as LightWeightM2M (LWM2M). A predetermined mapping (40) at the M2M device (20) maps action labels to library functions (22) of the M2M device (20), obviating the need for code in the M2M device (20) to interpret and execute actions.
