Tziporet,

Please apply this patch after the last doc patch I sent out on 11/27.  BTW,
I am still using the old filename.

Thanks,

Chien

+Recommended setting
+============================================
+RDMA connections use the same TCP port space as the host stack.  To avoid
+conflicts, set rdma_cm module option unify_tcp_port_sapce to 1 by adding 
+the following to /etc/modprobe.conf:
+
+    options rdma_cm unify_tcp_port_space=1

+============================================
+Known issues
+============================================
+On RHEL4 update 4, we have observed /dev/infiniband/uverbs0 does not
+always get created.  This device file is used for user-mode access to
+accelerated interface.  Current workaround is to change the start order
+for openibd(S05openibd) to after network(S10network).  For systems that
+start at runlevel 3 do the following:
+
+    mv /etc/rc.d/rc3.d/S05openibd /etc/rc.d/rc3.d/S11openibd
+
+For runlevel 5 do:
+
+    mv /etc/rc.d/rc5.d/S05openibd /etc/rc.d/rc5.d/S11openibd
+
+
+Some MPIs require the node that initiated the RDMA connection to send
+the first RDMA message.  Enable this feature by adding the following 
+to /etc/modprobe.conf:
+
+    options iw_nes send_first=1
+
+
+For Intel MPI, iw_nes currently does not support dynamic connection 
+establishment feature.  Turn it off by setting/exporting the 
+I_MPI_USE_DYNAMIC_CONNECTIONS variable to 0:
+
+    export I_MPI_USE_DYNAMIC_CONNECTIONS=0
