Talks
for 1st day – Wednesday, 11/28/07
The
first day includes presentations by SDM center members with emphasis on progress
in applying SDM center technology in various application projects, advancement
towards production use, and new technology advancements.
The first talk is invited to get familiar with CEDPS center technologies.
Session 1 (8:30 – 10:30)
Session 2 (11:00 – 12:30)
Session 3 (1:30 – 3:30)
Session 4 (4:00 – 5:30)
Mini-workshops Schedule and content
Purpose of mini-workshops: 1) to focus on specific topics of scientific data management needs in several application domains and identifying and delineating tasks to be performed jointly in the short run; 2) to identify joint tasks in collaboration with other SciDAC centers and institutions.
We planned on 6 sessions, 3 with application domains, and 3 with other centers/institutions.
Thursday Morning (parallel sessions)
o UltraVis-SDM mini-workshop
o Fusion-SDM mini-workshop
Thursday Afternoon (parallel sessions)
o VACET-SDM mini-workshop
o Climate-SDM mini-workshop
Friday Morning (parallel sessions)
o PDSI-SDM mini-workshop
o Groundwater and Kepler mini-workshop
Thursday Morning
UltraVis-SDM
mini-workshop
Date: Thursday morning, 11/29/07, 9:00-12:30
Title: Interactive Volume Rendering on Petascale Systems (with Ultravis
Institute)
Lead: Rob Ross
Task: Discuss next steps in enabling interactive volume rendering on
petascale systems, focusing on data organization and parallel
I/O. Perform detailed walk-through of I/O path on BlueGene/P
system, discussing how best to schedule I/O and how best to partition data
in the system. Gain an understanding of how multi-resolution data might change
the approach.
Ultravis Attendees: Hongfeng
Yu, Tom Peterka

Fusion-SDM mini-workshop
Date: Thursday morning, 11/29/07, 9:00-12:30
Title: Challenges for fusion simulations
Lead: Scott Klasky
Applications: Fusion simulation
Task: Discuss new challenges, including adaptive workflows, linking more provenance information of code coupling into the provenance tracking, data streaming mixed into the workflow, and dashboard changes for more analysis integrated into the dashboard.
Fusion Attendees: Seunghoe Ku, Stephane Ethier (tentative)
SDM essential attendees: SPA team members, Arie, SEA team representative

Thursday Afternoon
VACET-SDM mini-workshop
Date: Thursday afternoon, 11/29/07, 2:00-5:30
VACET Attendees: Wes Bethel, Hank Childs, Prabhat
Lead: Wes Bethel
Title: VisIt and Data Search/Query Interface
Applications: Accelerator Design, and Fusion (GTC)
Task: Identify the API for VisIt to use when calling HDF5-Fastbit. Discuss performance expectations, and taking advantage of parallel platforms.
SDM essential attendees: John Wu, Ekow Otoo, Chandrika

Climate-SDM mini-workshop
Date: Thursday afternoon, 11/29/07, 2:00-5:30
Title: Server-side workflow support
Lead: Arie Shoshani
Applications: climate simulation (which one?), ESG
Task: Evaluation of different models is planned to be realized in a systematic way by ESG and John Drake's SciDAC teams. The discussion will focus on identification of evaluation procedures that are common across the models and/or specific to a model; identification of analysis pipelines to be developed as part of the evaluation procedure; making sure that analysis procedures developed across different groups will be integrated into the ESG infrastructure; what format the analysis results should be stored for future reuse; what infrastructure the analysis should run and how the data management aspects of data analysis will be addressed.
Climate Attendees: Marcia Branstetter, Dean Williams, Don Middleton

Friday Morning
PDSI-SDM mini-workshop
Date: Friday morning, 11/30/07, 9:00-12:30
Title: Advanced, Structured Data Storage for Computational
Science Simulations (with PDSI)
Lead: Rob Ross
Task: Map out organization of structured datasets into FS objects,
taking into account common storage habits and access patterns of applications.
Discuss how these objects might be made visible by the file system (e.g. as
a directory hierarchy). Outline a high-level I/O API that would leverage this
approach.
PDSI Attendees: Garth Gibson, <graduate student>
SDM essential attendees: Rob Ross, Rob Latham, Alok
Choudhary, Wei-Keng Liao

Groundwater and Kepler mini-workshop
Date: Friday
morning, 11/30/07, 9:00-12:30
Applications: Groundwater
Lead: Terence Critchlow
Task: The purpose of this breakout session is twofold. First, we will work through existing bottlenecks and problems encountered using Kepler in the groundwater application (e.g. inability to execute multiple instances of Kepler concurrently from same user account) including detailed plans for overcoming these problems. Then we will delve into detailed design discussions in the areas of enhanced job launching, enhanced job monitoring, and provenance to identify areas of potential technical collaborations.
