NUMA Observability

This web page describes the work needed for observability, control, and diagnosability of lgroups in the system, kernel, and applications. Additional APIs, tools, statistics, dtrace scripts, and debugging support are needed.

Here is a wish list that tries to list the following:

• Classes of users for this work
• Useful questions they might ask
• Answers that can be provided now
• What would be nice to have

APIs

Tools

DTrace Scripts

Debugging

Benchmarks

• memtest – small microbenchmark to test memory latencies.

People
