Charm++ parallel programming system

That sounds promising but I'm not quite clear on what it means or how to use it to correlate. 

If it identifies the exact chare, then could it be used to identify specific chares outside of a chare array?

Does it identify the exact chare when not in a chare array and a chare array when the active chare is a member of such an array (using then the id 4-tuple to identify the exact chare)?

So far, I've been using exact match on the EVENT field to match a message CREATE event with its matching BEGIN_PROCESSING for only messages sent between chares that are parts of chare arrays. The CREATE event does not record an array index, but the EVENT field ensures the CREATE matches the BEGIN_PROCESSING, so what does EVENT mean here?

Thanks so much!

I believe you can use the "EVENT" field in the log, which (while badly
named) correlates all the instantiations of a given entity (chare,
chare array, group, etc.). Does this make sense?

/// BEGIN_PROCESSING MESSAGE_TYPE ENTRY TIME EVENT PE @2(MSGLEN)
///                  @4(RECV_TIME ID0 ID1 ID2) @7(ID3) @6.5(CPU_START_TIME)
///                  @6.6(NUM_PERF_COUNTS $NUM_PERF_COUNTS*PERF_COUNT)
