Introduction Parallel and Distributed Computing

What is GP-GPU Distributed Computing? Parallel: Processing concurrently

Distributed: Processing over many computers, typically in parallel, but not always Local Grid Computing

Ballou OpenCUDA + MPI

Applications of Supercomputing What can we do with Parallel and Distributed Computing?

Solving (Large) Linear Systems LINPACK Benchmarks

Fluid Dynamic Simulations N-Body Simulations Brute-Force Password/Hash Cracking Prime Number Searching Protein Folding Image Analysis / Manipulation ...

Facebook – Data Mining Universities Many Others

Ballou OpenCUDA + MPI

The Problem(s)

”Distributed Programming” is expensive Specificity of Hardware Data Distribution Volume

Fault Tolerance

Ballou OpenCUDA + MPI

A Framework Solutions

Ease Programming Interface for Highly Parallel Distributed Computing Allow for Diversity in Computing Environment Bring together ideas from both types of distributed computing ”Jungle Computing”

Ballou OpenCUDA + MPI

Plan and Goals

Develop a framework for distributed computing over a heterogeneous cluster Develop several different solutions for vascular extraction from CT angiography scans Profile the different solutions Add Cluster/ Node Configuration and Scheduling Options

Ballou OpenCUDA + MPI


Progressing more slowly than I anticipated CUDA C/C++ and pyCUDA Cluster/ Node Administration (ongoing) mpi4py – Begin learning the MPI interface and intricacies

Ballou OpenCUDA + MPI

Continuing Progress

Continue Learning mpi4py and pyCUDA Combine mpi4py with pyCUDA ... Begin developing framework
