Hi,<br>
I've red through the chapter in "Using MPI-2" about mutexes.<br>
Suppose that you know in advance that <span style="text-decoration: underline;">only one</span> cumputer (say node y) can access the memory-window on node x (except node x itself).<br>
How should your mutex-code look like (you still need a mutex, since
both x and y can access the memory)? (since you won't need the entire
"tree-mutex-code" provided by Rajeev Thakur, I guess, since there are
only two processes able to acces the memory...). I haven't enough
experience yet to find this one by myself, and really need it for the
program I'm working on.<br>
<br>
Thanks for any ideas/hints/help...<br>
