Abstract: A computer-implemented method includes managing function calls between a plurality of nodes and a super node of a rack system having a distributed operating system (OS). The OS includes a plurality of functions divided into first class and a second class, and each of the plurality of nodes excludes functions in the second class. Managing the function calls includes detecting a call to a first function on a first node of the plurality of nodes. It is determined that the first function belongs to the second class of functions and is not available on the first node. The call to the first function is routed to the super node, responsive to determining that the first function belongs to the second class, where the super node includes code for the functions in the second class.

Abstract: A method for hybrid arrival-occupancy based congestion management includes increasing a recent arrivals counter associated with a data flow from one or more sources in response to receiving a data packet from one of the sources and storing the data packet in a buffer including multiple storage units. The method includes determining if a buffer is congested, randomly selecting an occupied unit of the buffer and determining the source of the packet stored in the occupied unit of the buffer, generating a congestion notification message, sending the congestion notification message to the source of the packet stored in the occupied unit of the buffer if the recent arrivals counter exceeds a threshold value and decreasing the recent arrivals counter associated with the source of the packet stored in the occupied unit of the buffer and discarding the congestion notification message if the recent arrivals counter has a zero value.

Abstract: A computer-implemented method includes managing function calls between a plurality of nodes (120) and a super node (130) of a rack system (100) having a distributed operating system (OS). The OS includes a plurality of functions divided into first class (160) and a second class (165), and each of the plurality of nodes (120) excludes functions in the second class (165). Managing the function calls includes detecting a call to a first function on a first node of the plurality of nodes (120). It is determined that the first function belongs to the second class (165) of functions and is not available on the first node. The call to the first function is routed to the super node (130), responsive to determining that the first function belongs to the second class (165), where the super node (130) includes code for the functions in the second class (165).
