Designing multi-leader-based Allgather algorithms for multi-core clusters
The increasing demand for computational cycles is being met by the use of multi-core processors. Having large number of cores per node necessitates multi-core aware designs to ext...

A Scalable Asynchronous Replication-Based Strategy for Fault Tolerant MPI Applications
As computational clusters increase in size, their mean-time-to-failure reduces. Typically checkpointing is used to minimize the loss of computation. Most checkpointing techniques, ...

Web server protection by customized instruction set encoding
We present a novel technique to secure the execution of a processor against the execution of malicious code (trojans, viruses). The main idea is to permute parts of the opcode val...

Mechanisms and policies for supporting fine-grained cycle stealing
This paper presents an investigation into local mechanisms and scheduling policies that allow guest processes to efficiently exploit otherwise-idle workstation resources. Unlike t...
