Agenda

Prelim Outline
Timeline/Schedule

Tomorrow

• talk on Skype
• or meet late morning

Discussion

• Pavan has ECP project - use there?

Agenda

• what Pavan wants - MPI blocking calls block streams (but not others)
• idea: add streams to MPI calls
• MPI + OMP like behavior - multiple recvs in diff threads

Idea

• stream as an endpoint, like AMPI
  
  • e.g. spawn AMPI rank per GPU (in addition to any CPU)

Opportunity

• do what we can for our GPU runtime
• how to comm data in gpu device
• how to make streams wait for events such as recv

TODO

• Create our own direction
• Telecon w/ Pavan - in 1.5 weeks or so
• Research-y idea - lots of streams (like splitting stencil)
• Exp mesasure interfence on CPU side by NVIDIA
  
  • busy wait style calc - send messages to self
  • single CPU that launches kernels
  • view perf impact
• Next week - brainstorm project
• Review Nikolai's thesis
• Test out library (Juan)
• small app/benchmark - MPI based
