Distributed operating system functions for nodes in rack

摘要

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).
