Architecture Scalable Array of Microcomputers

• CPU - 1 GHz Athlon
• Memory - 1 GB/node
• Network - Dolphin/Scali
• Scalable - 132 nodes

4
Cluster Supercomputing Network!

• CPU speed is not the whole story.
• Many problems need a fast interconnect to use
  cluster CPU power.
• SAMSON design affords balanced performance.

5
SAMSON supercomputing speed

• Initial LINPAK benchmark 101 Gigaflops
• Expect improvements up to 160 Gflops
• Top 200 performance
• Scalable hardware and system performance

6
SAMSON and Supercomputing

• 100 Gflops (now) to 160 Gflops (June 01)
• 132 Gbytes RAM
• 80 Megabytes/sec all-to-all communication
• Bang-for-the-buck 2500 per Gigaflop -scalable
