This question was addressed offline while the mailing lists were offline.
We had things like hwloc_bitmap_set_ith_ulong() and
hwloc_bitmap_from_ith_ulong() for packing/unpacking but they weren't
very convenient unless you know multiple ulongs are actually needed to
store the bitmap.
We added new
Hello,
Suppose I call hwloc on two MPI ranks and get a bitmap on each. On rank
0, I want to bitwise OR the two. How to do that? I did not find bitmap
APIs to pack/unpack bitmaps to/from ulongs for MPI send/recv purpose.
Thank you.
