Linux_hpc_swstack - Sep 2008 - IB-related bug reports / enhancement requests

Hello,

Based on some experimentation I did today, I''d like to make the
following Infiniband-related bug reports and feature requests:

Bug Reports:

      * OpenSM doesn''t work with chkconfig, because of a missing
        chkconfig line in /etc/init.d/opensmd.  This means you can''t
        simply start a subnet manager as expected with ''chkconfig
        opensmd on && server opensmd start''.
      * IPoIB interfaces default to on and DHCP on the node that the
        distro/stack is initially installed on.
        See /etc/sysconfig/network-scripts/ifcfg-ib[0-1].  This is not a
        sane default for a node that will be the DHCP server.  Further,
        sunhpc_setup refuses to run, with out-of-the-box ifcfg-ib[0-1],
        due to missing directives like IPADDR, NETMASK, NETWORK etc. 

Feature Requests:

      * OFED 1.3.1 or greater.  I''m going to be running this stack on a
        large IB-based machine with a non-traditional network topology.
        This machine will require SM routing capabilities and IPoIB
        performance that aren''t present in the OFED v1.2.5.5 that
you''re
        currently shipping.
      * I need a DHPCd that''s patched to support Infiniband.  It would
        be very nice for this to be available out-of-the-box.  See the
        patches available here:
        http://www.mellanox.com/products/boot_over_ib.php

Thanks,

-Matthew

Dear Matthew,

Thank you very much for your feedback!

I created the following entries in our buzilla database:

Bug 17012	OpenSM doesn''t work with chkconfig
Bug 17013	sunhpc_setup refuses to run due to missing directives like 
IPADDR, NETMASK, NETWORK etc
Bug 17014	Upgrade to OFEB v1.3.1 from current v1.2.5.5
Bug 17015 	Support Boot over IB

They are on our to-do list now. :-)

Best Regards,
Zhiqi
