Hewlett Packard Enterprise is a global leader in supercomputing; designing and building some of the worlds most advanced computing systems for government, industry and academia. Cray initially hired me as a contractor in 2012. 18 months later I was hired permanently. In 2019, Hewlett Packard Enterprise (HPE) acquired Cray.

Development of HPE Dragon Runtime

Dragon is a cross-platform distributed runtime environment enabling applications to easily scale from a single CPU to an entire cluster. Initial releases of Dragon are expected to retrofit and enhance the standard Python multiprocessing library. When run using the Dragon runtime, Python applications using the standard multiprocessing benefit from increased scale and quicker time to solution. 

Development of HPE Cray EX Image Management System (IMS)

Subject matter expert and lead developer for the HPE Cray EX Image Management System (IMS) used to build & customize node images. IMS reimagined the legacy image management tools for the HPE Cray EX system. The IMS Service runs as a Kubernetes pod within the HPE Cray EX cluster. IMS exposes a RESTful CRUD API managing bootable images, image recipes, SSH public keys and IMS jobs. IMS Jobs can be used to build a new bootable image from an image recipe or enable the customization of an existing bootable image.
