ASIC Method II

1
ASIC Method - II

• Supercomputing Lab.
• Lee Hwang Jik

2
Problems

• Compression
• The Compression Ratio of LZW is not good.
• Prove PMB Benchmark Result
• Use the LZO compression which used in the PACX
  Library
• ASIC method
• NWS
• Implement component as NMC

3
Current Status (1/3)

• Using LZO compression
• Include Compression in MPICH-G2
• Specification
• Message size is above 256byte
• Compression message size is small than original
  size
• Comparing LZO with LZW
• In PMB benchmark
• LZW
• Compression message size gt original size (Mostly)
• LZO
• Compression message size gt original size (Nearly)
• ASIC and NWS component isnt implemented.

4
Current Status (2/3)

• Result of PMB (Local Area)

5
Current Status (3/3)

• Result of PMB (Wide Area)

6
Usage of the Model

• LogGP model

7
Future Work

• Implementation (one week)
• ASIC method (handle RSL file)
• NWS component
• Performance analysis (Using PMB)
• Non-Compress vs Compress
• MPICH-G2 vs ASIC-method
• Best case
• Several processes having local and wide area
  compute the complicated work
• Writing paper (Dead line February 1, 2003)
