Thanks a lot! This is great fun to watch!
I suppose to make actual use of it, I would need ways to slow
down/pause/rewind execution of the trace, but even so it makes for good
entertainment :-)

Re: [Valgrind-users] Visualizing memory traces using valgrind
Slow down / pause is something that's planned. Rewind is difficult since
this would require actually logging the trace data (currently it's
transient), which would take up a huge amount of space - though this may be
useful for short-lived programs.

You could use client requests or some other mechanism to allow user programs to place calipers around a particular region of the code that are deemed interesting. Then you would only need to track current state (no tracing) until the measured region begins and you could stop emitting trace data as soon as the region ends. -Dave -- Precog is a next-generation analytics platform capable of advanced analytics on semi-structured data.

Hi Is it possible to turn logging on and off (either internally or externally)? Would it be possible to detect patterns of activity (e.g. from loops) and store only the X most common patterns?

Re: [Valgrind-users] Visualizing memory traces using valgrind
For logging, perhaps a record button that would record up to some fixed cache size and then auto-pause the program. To continue, the cache would need to be cleared. Data mining the trace is a great idea, a simple use case I was considering was to detect data stride / structure size to better layout arrays of structures.
