| Abstract: |
A parallel algorithm applicator has recently been added to the AIPS++ system. This applicator class can be used for algorithms that can carry out significant work across multiple processors with little or no communication between the processors. This demonstration will show the first use of this class to deconvolve a large spectral line cube within AIPS++. The demonstration will be running remotely on one of the NCSA Origin2000 systems. The implementation of parallel processing is with the Message Passing Interface (MPI). MPI is a portable system that allows data and instructions to be sent to remote processors (either on the same machine or on different machines). Thus, the potential speed-up demonstrated on the highest-end systems available at large centers, such as NCSA, can be realized in part on a modest multiple-processor computer systems as well. |
