Conventional security exploits have relied on over-writing the saved return pointer on the stack to hijack the path of execution. Under Sun Micro-system's Sparc processor architecture, we were able to implement a kernel modification to transparently and automatically guard applications' return pointers. Our implementation called StackGhost under Open-BSD(More)
Automated system deployment frameworks and configuration management systems have been in wide use for a number of years. However, due to increasing pressures to maintain high availability, coupled with the price effects of commodity servers, administrators may be required to deploy large numbers of systems in shorter time frames than is normally possible(More)
HPC environments have traditionally existed installed directly on hardware or through virtual machine environments. Linux Containers, and Docker specifically, have gained extensive popularity; we believe this current trend toward containers and microservices can be applied to HPC to improve efficiency and quality of development and deployment.

With the high powered rendering systems and recording equipment available today, 4k video streams are now within the reach of several scientific communities. A resolution of 4096x3072, with 24-bit color, running at 30 frames per second, produces just under 10Gbs of network traffic. Existing tiled displays are being used to show such media, and these high(More)
Utilizing a combination of above-canopy and intracanopy lighting may prove highly beneficial in a Lunar Controlled Ecological Life Support System (LCELSS) as a means of increasing volumetric efficiency of plant growth. Intracanopy lighting was not found to be detrimental to plant tissue and production per plant when cowpeas were grown using sand culture.(More)
