The heterogeneity of resources in computational grids, such as the Canadian GridX1, makes application deployment a difficult task. Virtual machine environments promise to simplify this task by homogenizing the execution environment across the grid. One such environment, Xen, has been demonstrated to be a highly performing virtual machine monitor. In this(More)
The deployment of HEP applications in heterogeneous grid environments can be challenging because many of the applications are dependent on specific OS versions and have a large number of complex software dependencies. Virtual machine monitors such as Xen could be used to package HEP applications, complete with their execution environments, to run on(More)
Selective gonadal venography was performed on 9 adult patients with 11 nonpalpable undescended testes. The gonad was accurately localised pre-operatively on 7 occasions. Testicular agenesis was predicted in 2 instances and strongly suggested in 2 others. Four failures were recorded, 2 on the right and 2 on the left. Accurate pre-operative localisation(More)
partment of Physics and Astronomy. Over the course of my first work term in the Computer Engineering program, following my 3A academic term, I was involved in a year long project to evaluate a new implementation of grid computing based on Web services middleware. My specific research tasks included grid system design, deployment, administration, computer(More)
