Hong, Yu-Ju. Ph.D., Purdue University, December 2013. Mitigating the cost, performance, and power overheads induced by load variations in multicore cloud servers. Major Professor: Mithuna Thottethodi. Load variations whether in space or time pose a significant challenge to system designers. These load variations may induce inefficiencies such as load imbalance and overprovisioning, resulting in...

We study an online problem in which a set of mobile servers have to be moved in order to efficiently serve a set of requests that arrive in an online fashion. More formally, there is a set of n nodes and a set of k mobile servers that are placed at some of the nodes. Each node can potentially host several servers and the servers can be moved between the nodes. There are requests 1, 2, . . . tha...

software deployment, software installation, diskless, network storage This report briefly summarizes a number of recent investigations related to software deployment on network storage based systems that our team recently performed. A specific context in which this was investigated was for a pool of general-purpose servers in a single data center that are to be allocated among different applica...

This paper examines the construction of a cost-effective storage cluster for an IBM Blue Gene/L supercomputer on the TeraGrid. The performance of storage clusters constructed using commodity Opteron servers and directly-attached fibre-channel RAID systems is analyzed utilizing the GPFS, Lustre, and PVFS file systems. In addition to traditional client scalability results, server scalability is a...
