introduction

new technologies and "paradigms" are changing how we think of "data" and "compute".

both are becoming increasingly "mobile"

ChRIS

Research

Integration

Service

ChRIS

need to address the problem of "simple" distributed/cloud computing from medical compute perspective


overview / goals

as low as possible barrier of entry to developer

not be concerned about infrastructure details

write/develop as if running on a local (*nix) environment

be able to deploy the entire "cloud" system locally for testing/developing/deployment


overview / goals


overview / goals

how do I run this on the cloud?

how do I run this on "someone else's computer"?


overview / goals


overview / goals

containerization about the app itself

pervasive use of docker and docker hub

system handles I/O using simple FS abstractions

RESTful services -- multiple front ends to a single backend


overview / goals

CHRIS...

CHRIS is a bio-medical data workflow manage that allows easy and intuitive collection, analysis, and sharing of data between parties.

  • allows for advanced view rendering
  • allows for sharing of images
  • allows for immersive real time collaboration
  • allows for post-processing of images

many data sources... many compute sources...

and compute!

timing can be complex...

PUSH data

separate coordinator service

WAIT!

EXEC on data

app to CHRIS...


BU partnership

Boston University Computer Science

Mentoring students on Cloud computing

Academic partner on the MOC


RedHat partnership

RedHat is active partner developing CHRIS infrastructure to the MOC

CHRIS as platform to help foster community and opensource development in the cloud using this paradigm

RedHat interested in helping use CHRIS to be a platform for "hack-a-thons" based on openswift, kubernetes, etc.
