Targets

Cluster Linux and IRIX build maintenance

Maintenance of the existing NCSA/NRAO builds under IRIX and on the AHPCC Linux cluster. (WY, H, 3 wk, DM, H, 3 wk).

Key project processing

Processing of five key projects (including at least one each of mosaiced, wide-field or large spectral line). Candidates include the existing M33 dataset (Westpfahl), TXCam (Kemball), and a selection of low-frequency VLA projects in A-configuration. Generation of user liaison documentation and user support at NCSA. (RP, H, 4 wk, DM, M, 2 wk, AK, H, 2 wk).

Complete multi-field parallelization

Complete implementation of a prototype parallelization for mosaiced or wide-field imaging. Candidates include field- or facet-based gridding, model prediction or residual image computation. (KG, H, 4 wk).

dragon revisions for automated wide-field imaging

Refine dragon for full wide-field or deep field reduction. (KG, H, 4 wk).

Parallelization of other deconvolution methods

Extend the Clark CLEAN parallelization to other deconvolution algorithms. (KG, H, 2 wk).

Initial parallel I/O implementation

Implementation of multi-process I/O on the same file, multi-iterator access in a single process, and ROMIO asynchronous I/O using MPI-2. Evaluation of performance in these cases. (WY, H, 5 wk).

Complete NT port of libaips and libtrial

Continue and complete the NT port as described; run a parallel application on the NCSA NT supercluster. (WY, H, 5 wk).

Modify test suite for large problem size

Modify the current bigimagertest to use simulated data. (DM, H, 1 wk).

Serial profiling

Continue to document serial profiling of mosaicing, wide-field and spectral line performance for large problem sizes. Identify and eliminate gross serial optimizations. (WY, H, 2 wk).
