Re: [Valgrind-users] multiple cores being used?

[Brian B. <bri...@gm...>]

Hi Paul.  I am at <20% of memory use.  I should also note that I followed
Julian's advice for increasing vg_n_segments and memory size to 128 GB.

Does valgrind itself do anything multithreaded?  My program uses all cores
on the machine at various stages of the program running.  But my
understanding was that it was always serialized while running memcheck.

Thanks. Brian
