Applications Workshop
From Modelado Foundation
Last edit - (9/25/14)
Date: September 30, 2014 - October 2, 2014
Location: Hillsboro, Oregon, Ronler Acres Bldg. #2, 2501 NW 229th Ave, Hillsboro, OR, click here for Google Map --> [1] We will be in the MPR room. Please come to the visitor desk and we will have badges and wifi credentials ready for you.
Purpose
Bring application scientists and computer architects together to implement physics codes in the exascale-capable Traleika Glacier programming environment. Assess progress, review plans for the remaining year of the project and Do some hands-on coding together.
The 3rd Applications Workshop comes at the 2/3 mark of the project. The TG architecture was frozen as of July 1. and is captured by version 4.10 of FSIM. OCR is at version 0.9 and runs on x86 as well as on the TG architecture as represented by FSIM. We have several full proxy applications and numerous kernels implemented on OCR, either directly to the API or through one of the higher level notations, CnC, HTA, R Stream. We now have the ability to do performance and data movement studies comparing applications in their original form with refactored versions on OCR and OCR-on-TG. This workshop will allow us to work on these assessments and begin to make statements about performance and energy projections to exascale resulting from the revolutionary software and hardware architectures of this project.
Goals
- Show TG's part in the entire strategy to exa-scale
- "Sync-up" the entire team on status of the hardware/software architectures and the applications
- Define the metrics by which we will measure progress
- Let's code ...
