Hi list, Is there anybody who can give ben a exact answer? Thanks. --Junchang ---------- Forwarded message ---------- From: Junchang Wang <jun...@gm...> Date: Sat, Apr 3, 2010 at 8:05 PM Subject: Re: valgrind problems To: ben...@ya... Hi ben, Xeon 5410 was used in my previous work. If I specified the type of L2 cache, valgrind worked fine. What's your hardware configuration? I suggest posting your mail on Val...@li... for more help. --Junchang On Fri, Apr 2, 2010 at 9:56 PM, <ben...@ya...> wrote: > I have read your message about the cache L2.
