Minutes of the MPI working group

Thursday September 28, 2000 at 11:00AM - 12:00AM PDT

Next Meeting: Thursday October 5, 2000 at 11AM (CIT will call 414-229-6508).

Review progress with LALWrapperInterface and trivial dso
Jolien Creighton reported that the LALWrapperInterface is written, but there is a problem compiling it using autoheader. He is working to sort out this problem and commited to having it resolved by Monday October 2. Duncan Brown is ready to write the trivial shared object. It will be ready by Monday October 2.

Work plan for wrapperAPI
The workplan was reviewed, and the following dates and issues were discussed.

• October 10 will be the next ASIS telecon where we will explain the method for writing search code to run under the wrapperAPI.
• The first debugging phase of the wrapperAPI combined with a dso written to the new baseline requirements will begin by October 12.
• October 26 is the target date to have wrapperAPI running on the Beowulf at UWM and the prototype Beowulf at Caltech (if it is ready).
• The debugging phase from October 26 - November 14 is intended to include verification and validation of the wrapperAPI and the inspiral shared object library. It is also intended to integrate the mpiAPI and the wrapperAPI during that period of time.
• The second shared object for the MDC will perform an excess power search. There is nobody currently tasked to produce this dso. Flanagan is unlikely to be interested. So we need to find somebody else. Sam Finn was suggested.
• The MDC is scheduled for January 15-21, 2001.

Status of the wrapperAPI
Phil Ehrens reported on the status of the mpiAPI. It is fully integrated as an LDAS API. It is running as a command parser and outputs the user command that will be sent to the wrapperAPI. Code exists to handle the socket communications with the wrapperAPI. There are examples of the output logs in the LDAS system development logs. Links will be added to the main mpigroup page. Phil will document the use of mpiAPI on a web page and set up a way to exercise the code by returning the user commands to people by e-mail. People should send phil@ligo.caltech.edu an e-mail with a simple password.

Any other business
At next week's meeting the workplan for the mpiAPI and the integration phase of all LDAS components needed for the MDC will be discussed. These plans will assembled by Brady with input from Ehrens and Blackburn. Brady will also provide an outline of the presentation to be made to the ASIS working group describing wrapperAPI implementation and how to build a dso.
