Hi,

 

This is somewhat irrelevant question. It was said that in order delivery is a feature of Mellanox HCA and not part of IB spec. Is this true for UD type QPs also for which IB spec says that "in order delivery" is not guaranteed ?

 

Regards

Sunil

Comment (by gleb):

Actually in order delivery is a feature of Mellanox HCA and not part of
the IB/iWarp spec.[[BR]]
See [ http://openib.org/pipermail/openib-general/2006-August/025305.html]
for discussion about this. So use_eager_rdma flag is a good candidate to
be put in mca-btl-openib-hca-params.ini file.
