Re: Can you run two instances of valgrind on separate nodes in a multi-core NUMA environment?

I don't follow the details exactly, but FWIW .. valgrind running an
application is "just another normal process".  It has no understanding
of or special-casing relating to NUMA, or particular cores/nodes in a
multiprocessor machine.

Also, there is no gdbserver involved unless you start it with specific
flags to invoke GDB support.  But that is not the default.

It might be that if you are doing cross-process synchronisation via
accesses to shared memory, that depend on specific details of the machine's
memory coherence model, that you could wind up with problems.  Something
like that I could believe.
