Memgraph – heap visualisation for multithreaded programs

"Every allocation is drawn in real time in a little gui window with the relative addresses mapped to 2D hilbert space; where different colors will be used for different threads. The brightness of the allocations fades with time, showing you which allocations are new and which have been around for some time."

"Memgraph is not a proper profiler, nor does it provide precise instrumentation. Instead it relies on the power of your own visual cortex to get a proper "feel" about the application's behavior."
