In trust-based network computing environment, in order to establish a harmonious network environment, and enhance the network resources sharing utilization, resources scheduling research faces more problems than ever before. A resource scheduling algorithm, using cooperative particle optimization and putting task completion price and overall system trust benefits as optimized object, is proposed based...
Access control is a significant concept in the fields of information security. However, to date, it is still difficult to design an effective access control mechanism to support numerous users incorporating numerous different roles. In this paper, we present a hierarchy controllable user access control model based on traditional RBAC (HCRBAC). The permission lock technique which can effectively control...
As technologies such as symmetrical multiprocessing (SMP) and multicore processor (MCP) advanced, more and more computational cores are contained in one node. Therefore, parallel applications running on a cluster can exchange data among processes through either intra-node or inter-node communication. This gives rise to the question of how much network bandwidth impact on parallel computing performance...
