Virtual cluster on Comet is a project to provide a virtual cluster to HPC users on Comet resources in on-demand fashion . This marries the cloud computing usage scenario and the traditional HPC resources. On one hand, it provides a fully user-controlled cluster with totally customizable OS and software and service stacks; on another hand, this is built on top of HPC environment so users get a close-to-baremetal experience with regards to the performance.
The projects consists of a set of backend configuration scripts; a comet nucleus API; and a client side tool - cloudmesh comet - to enable users’ interaction with the system.
Since the inception of the project, we had ~15 different groups that used this feature.
We are also working on providing a templated environment for dbGaP researchers, in which we provide customized configurations on top of preset dgGaP images, based on the common Comet VC feature, to provide dbGaP researchers a computing environemnt that meets the usage guidance of dbGaP data .
