- Ensure to convert base_shared_mem_flags to be a relative offset in the global storage, and then to convert that back to an absolute virtual address before we try to use it - Don't double increment n_local_procs when calculating the peer rank during bootstrapping of the different base address case Something else is still wrong; if mmap() returns a different base address, things don't work (i.e., segv or hang forever when you try to send a message). More specifically, the bootstrapping now seems to correctly handle the case when mmap() base addresses are different, but the message passing does *not* -- it always assumes that the mmap() base addresses are the same. Still working on the fix for that -- want to checkpoint what has been done so far to facilitate working on different machines... This commit was SVN r8134.
