Abstract:

--------

 

The trend to exascale is causing researchers to rethink the entire computational science stack, as future generation

machines will contain both diverse hardware environments and run times that manage them. Additionally, the

science applications themselves are stepping away from the traditional bulk-synchronous model and are moving towards a more

dynamic and decoupled environment where analysis routines are run in situ alongside the large scale simulations. 

 

This thesis presents CoApps, a middleware that allows in situ analytics applications to operate in a

location-flexible manner. CoApps also explores methods to extract information from, and issue management operations

to, lower level run times that are managing the diverse hardware expected to be operating on next generation exascale machines.

This work leverages experience with several extremely scalable applications in materials and fusion, and has been evaluated on

machines ranging from local Linux clusters to the supercomputer Titan.
