[Valgrind-users] False Sharing Detection

[Ivan N. <nov...@gm...>]

Hi,
I would like to detect cases of false sharing in my program.

By this I mean cases where multiple threads are both trying to write data to
different memory locations but those locations are closest enough in memory
that they are on the on the same cache line.

The result would be delays on threads even though there are enough CPU's to
do the work.

Are there any tools in valgrind to do this?

Regards,
Ivan Novick
