AIPS++ Requirements and a Tentative Time Table

AIPS++ Requirements

• Glish changes. Changes to Glish internals to include machine-specific system calls required to execute a process on a particular processor must be carried out.

• File access and locking. AIPS++ must have the capability to lock files and control file access when separate processors are working on separate parts of data in the EP case.

• Selection of f77 and HPF code. The AIPS++ installation system must be able to select between f77 and HPF Fortran subroutines, depending on whether the site has an HPF compiler.

• User input of number of processors. The user interface must have the ability for the user to indicate how many processors (ultimately what machine the processors are on) to use for a task execution.

Tentative Time Table

Pre-1997

• Distribute Parallelization Plan to AIPS++ Programmers.

First Quarter 1997

• Implement calls to existing tuned HPF libraries.

• Rewrite existing Glish internals to allow machine calls to select processor numbers.

• Parallelize simple spectral line imaging and deconvolution in Glish.

Second Quarter 1997

• Import pulsar de-dispersion software, parallelize at fine grain.

• Parallelize sorting and gridding at fine grain.

Third and Forth Quarters 1997

• Parallelize antenna-based calibration and self-calibration.

• Investigate parallel solutions to linear problems with no-linear constraints (similar to Briggs NNLS).
