Thanks for the quick response, and sorry for the false bug report.
What's the proper forum for asking questions about how to use the API?
The documentation is rather slender. :-)
In particular, I'd like to know if this is valid code for binding the
memory to node 0, regardless of the number of nodes on the system:
{
unsigned long mask = 1;
struct bitmask nodemask;
nodemask.size = 1;
nodemask.maskp = &mask;
numa_set_membind(&nodemask);
}
I tried calling set_mempolicy directly for this trivial case, but I get
EINVAL when I try:
{
unsigned long mask = 1;
set_mempolicy(MPOL_BIND, &mask, 1);
}
Increasing the 3rd arg from 1 to 2 seems to solve the problem, but I cannot
understand why from "man 2 set_mempolicy".
Any guidance on these issues or pointers to where to find help would
be appreciated.
Thanks,
Andy
