In Search of a Framework for User-Oriented Data-Driven Development of Information Systems

Construction of a User-Oriented Usability Metric Model for High-Performance Computer Systems

“…Although these cluster systems are different in scale, their architecture is the same, that is, the whole system consists of several nodes, the simplest cluster can be composed of master nodes and computing nodes, for a slightly larger cluster, the master node may also be subdivided into landing nodes, storage nodes, etc., and the main task of this system is to undertake the computing nodes; each node can be a separate workstation with some independence, the systems of the compute nodes are mirrored to each other, all nodes are interconnected through high-speed networks, the tasks are distributed to each compute node through message passing communication, the advantage of this loosely coupled cluster system that is not a single system mirror is that it is low cost and easy to build and implement in a certain scale, and also, the disadvantage is that the loosely coupled whole system leads to more complex management [6]. There are already some studies on supercomputer performance evaluation [7] and operation monitoring [8], but for evaluation systems, individual vendors have some closed evaluation tools, but the implementation of these tools is mostly not publicly available and often developed only for their software and hardware characteristics, without universality [9].…”
