Is there any description of network packets formats, which are utilized by HPC services mentioned in
Appendix 1: HPC Cluster Networking
BTW, are formats of MPI messages packets vendor specific or is there any standard of those network packets?
The document in link
http://technet.microsoft.com/en-us/library/cc719008%28v=ws.10%29.aspx is about network topology (for example, how many networks each computer has). It is not related to and won't affect any network packet format.
the MS MPI message packet format is the same to MPICH2's format shipped by ANL. It is not vendor specific.
Hope this helps
