Also, what is your system configuration, there may be unknown issues with hardware that we havent tested with yet. > > So I have questions. PVFS2 say it support IB.

There is also support for the Mellanox-VAPI equivalents. To configure the openib version, I use the following line when building/configuring, a similar version of this should be sufficient for you to get things going, at least using RDMA/IB: ./configure --with-openib=/usr --with-kernel=/usr/src/linux-source-2.6.16 make && make install Hope this helps, -- Kyle > > Regards, > > Thank you in advance for valuable comments. > > Hyeyoung cho > > ------------------------------------------------------------------------ > > _______________________________________________ > Pvfs2-users mailing list > [email protected] > http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users > > > > -- Kyle Schochenmaier [EMAIL PROTECTED] Research Assistant, Dr. Brett Bode AmesLab - US Dept.Energy Scalable Computing Laboratory _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
