Access Issues

Can we mmap an entire Python address space into our monitor at some offset?

If not, can we use an incremental mmap technique that still gives good performance for the kinds of accesses we need to do?

If so, can we reuse the virtual memory hardware

The Dial Idea: turning down sensitivity for graphics updating or for event buffering/reporting, in order to achieve performance goals.

Four Ideas for a paper

Port Alamo to Python
Measuring the amount of indirection (and other redundant calculations) in the virtual machine, relative to the actual actual productive work getting done. (like heat loss in an energy transformation)
Dynamic Profiler - GUI, dials, watches and reports at multiple granularities of time steps
Redo Python so it can be easily multiprogrammed and/or is properly reentrant and thread-safe yet amazingly efficient.

Even though the Python Software Foundation grant may not loom large on Rincon's radar, participating in that community and getting its sponsorship might add credibility with other funding agencies.

Rich is working on C instrumentation on Monday. Meeting with Mike, Rich, and Clint on Tuesday afternoon, tba. We hope to get some additional events (such as list or memory events) instrumented and new visualizations working before Rich leaves.
