The short story is that Array Visualizer was the work of a wonderful engineer, John Readey, who left Intel (his choice).  At that time, management decided that it wasn't worth assigning another engineer to.  Over the years, I've been trying to get people interested in AV and have found an engineering group willing to take it on, but management still doesn't think it's worth the resources, so the effort is stalled.

Array Visualizer was part of Digital/Compaq Visual Fortran Professional Edition, and was completely rewritten and improved as part of Intel Visual Fortran.  It was never sold separately (there was a free "array viewer" download which lets you run applications that use AV but not develop new ones.)  Note that not only is Array Visualizer integrated with the debugger, but it can be used on its own from Fortran, C++, VB and other languages.  It also has support for HDF5.

I'd be happy to hear more from others of what Array Visualizer means to them and how they think it would benefit the product and Intel.  Indeed, I've VERY recently been asked to collect such comments, so you've given me a good opening.  Reply here or send me mail at steve.lionel at intel.com - it would be more helpful if you include your name and company/organization.
