George Bosilca 75a35ed7ee Implement the PUT protocol over MX. The send/receive approach give the best

performance on a 2G Myrinet card, as it look like pipelining the messages
by 1M is faster than a simple send/receive. However, when using a 10G card
the send/receive will limit the maximum bandwidth to 2.5Gbs. The reason is
the scarce bus resources that have to be shared between the Myrinet hardware
and the memcpy operation. The PUT protocol remove the memcpy, we now have a 
true zero-copy mechanism. But, there is no pipelining yet as it look like the
RDMA pipeline somehow disappeared from the OB1 PML ...

This commit was SVN r12925.

attribute

Complete next round of message size reduction: "strip" the descriptive info from the returned values. I have now added a flag to the gpr address mode (ORTE_GPR_STRIPPED) that instructs the gpr to not include segment names or tokens in the returned gpr_value_t objects.
