IRIS DMC - Short Course

‘Introduction to Multinode Computing using MPI (Message Passing Interface)’

Stevenson, Washington    June 3, 2008

 

Workshop Information

 

 

Background

IRIS-DMS will sponsor a one-day tutorial on how to utilize multi-node parallel computing by using the MPI (Message Passing Interface) library within your geophysical software codes.  Many of us have access to in-house or campus multi-processor computers.  However, in order to access many computing nodes at one time, particularly those distributed across a cluster, our software codes need to be programmed to ask for and to compute on the many nodes.  Currently the most commonly used method to perform this task is MPI, a set of library calls that performs the communication to the multiple processors.  MPI enables an application code to access from two to 512+ nodes (desktops to national supercomputer sites).

Scope

The full-day pre-workshop tutorial will provide an overview of multi-node parallel computing strategies including one-task-many times (e.g., thousands of cross-correlations) and one-task parsed and distributed across many processors (e.g., 3D finite difference algorithm).  Future directions of parallel computing will also be discussed.  MPI basics will be presented.  During the tutorial, participants will gain hands-on experience of writing simple codes containing MPI and then on how to run these codes.

Participation

In order to keep the workshop efficient, we are limiting the short course to 25 participants.  Graduate students are highly encouraged to register.

Short course registration will close April 25, 2008.

Participants that are selected will be notified by April 30, 2008.

Participants are required to bring their own laptop computers; remote login access using ssh via a terminal session is needed.  Tutorial instructors will provide access to a multi-node facility at their national computing centers; participants should be familiar with UNIX/Linux and either C or Fortran.

Financial support

There will be no registration fee.

The IRIS Data Management System will pay for one night of lodging (June 2, 2008) and breakfast-lunch will be provided.

Support will only be provided for applicants from IRIS Full Member Institutions.

      

Dates and Venue

Continental-breakfast will be available at 8-9 am on June 3, 2008; lunch will be available at 12 noon.

The workshop will be held from 9 AM until 5 PM on June 3, 2008 at the Skamania Lodge in Stevenson, Washington, just prior to the IRIS Workshop.
