Hi, looking all around my MPI refs, ["Using MPI", the HP manual,
URL's all around] I could find refs on how to simulate shared memory,
but not on how
to use it. My code constantly refers to, but does not modify, a huge
array,
but the processors should be able to refer to the same memory block.
Unfortunately, while chapters abound on how to construct the right
datatype
and send it in a message, I could find nothing on how to just pass a
pointer.
Could anyone please tell me how that might be accomplished?

Apologies if the answer is staring me in the face.
Multiple answers will be compiled and posted;
please CC replies to omri 'at' biophysics 'dot' lanl 'dot' gov

Thatnks in advance.
