Re: [Valgrind-users] Multicore/multithreading and memory trace

[Milind <km...@gm...>]

Thanks for the quick reply Tom.

I (again) went over the para that you have pointed out. Most of the
discussion in that para and the Helgrind discussion seem to revolve around
single CPU. I am not seeing any references to multicore system with
concurrent running of threads . Multiple threads, synchronization between
them, deadlocks etc all seem to be talking in the context of a single CPU.
Hope I am not misreading.

I am looking for collecting memory traces for a multicore, multithreaded (hw
threads) program.

Thanks,
- Milind
