Many-Task Computing on Many-Core Architectures

Many-Task Computing on Many-Core Architectures

Many-Task Computing (MTC) is a common scenario for multiple parallel systems, such as cluster, grids, cloud and supercomputers, but it is not so popular in shared memory parallel processors. In this sense and given the spectacular growth in performance and in number of cores integrated in many-core architectures, the study of MTC on such architectures is becoming more and more relevant. In this...

Isolated Execution on Many-core Architectures

We explore how many-core platforms can be used to enhance the security of future systems and to support important security properties such as runtime isolation using a small Trusted Computing Base (TCB). We focus on the Intel Single-chip Cloud Computer (SCC) to show that such properties can be implemented in current systems. We design a system called SEMA which offers strong security properties...

Co-scheduling on Upcoming Many-Core Architectures

Co-scheduling is known to optimize the utilization of supercomputers. By choosing applications with distict resource demands, the application throughput can be increased avoiding an underutilization of the available nodes. This is especially true for traditional multi-core architecture where a subset of the available cores are already able to saturate the main memory bandwidth. In this paper, w...
