Heirarchal Data Partitioning For Linear Algebra Kernels on Clusters of Clusters (Other)

Conducted by

Brett Becker

Description

We are currently working on a new heirarchal data partitioning scheme for linear algebra kernels on clusters of clusters. Our primary focus is on minimising the amount of inter-cluster communication. Other avenues include overlapping communication and computation and expanding the data partitioning scheme to other architectures and problem domains.

Status

in progress

Resources

  • Nodes involved: 100
  • Sites involved: 3
  • Minimum walltime: 1h
  • Batch mode: yes
  • Use kadeploy: no
  • CPU bound: yes
  • Memory bound: no
  • Storage bound: no
  • Network bound: no
  • Interlink bound: no

Tools used

Open-Mpi, Infiniband

Results

A new partitioning algorithms for matrix multiplication and related operations designed for use on a small number (2, 3, ...) of clusters/sites has been developed and demonstrated which minimizes the total volume of inter-cluster communication optimally, and better than all other known data partitioning algorithms.
