<br><font size=2 face="sans-serif">Hi Folks,</font>
<br>
<br><font size=2 face="sans-serif">I have a IB network which consists of
only a single unmanaged switch, all end nodes connecting with the switch
only need to do RDMA read/write operation with each other. My question
is, what are the indispensable modules in driver's core and opensm that
make the network up and run? </font>
<br>
<br><font size=2 face="sans-serif">I've been using only ib_mad module in
driver's core with a managed switch before, and the network works fine.
So I assume that only the ib_mad module in driver's core and SM in opensm
are mandatory in my network. The LIDs are assigned by them. The SA and
CM modules are not useful in my case. Am I right?</font>
<br>
<br><font size=2 face="sans-serif">I need to minimize driver and opensm
to fit them in my network, the HCA driver is mthca.</font>
<br>
<br><font size=2 face="sans-serif">Best,</font>
