What is Titanium?

• Java with
• multidimensional arrays
• static threads in a global address space
• collective communication/synchronization
• fast bulk I/O
• Applications
• simulation of the human heart
• genome application for isolating genes
• DB primitives (join, sort)
• multigrid solvers, matmul, LU, FFT, ...

Titanium and ISTORE

• Is ISTORE a good machine for HPC in Titanium?

• No, designed for storage apps

• Is AME a good goal for Titanium?

• Yes, AME is a good idea for compute-intensive
  apps too
• Consider 1 M processor machine

AME for Compute-Intensive Tasks

• Two kinds of applications
• Regular, bulk-synchronous
• Irregular, task-queue scheduled
• Availability benchmarks and fault injection.
• Prediction the irregular ones will be easier
