4.1.3. Running WD-UDP in debug mode

To use libcxgb4_sock’s debug capabilities, use the libcxgb4_sock_debug library provided in the

package. Follow the steps mentioned below:

i. Make the following entry in the /etc/syslog.conf file:

*.debug /var/log/cxgb4.log

ii. Restart the service:

[root@host]# /etc/init.d/syslog restart

iii. Finally, preload libcxgb4_sock_debug using the command mentioned below when starting

your application:

root@host]# LD_PRELOAD=libcxgb4_sock_debug.so CXGB4_SOCK_DEBUG=-1

<pathto>/your_application

4.1.4. Running WD-UDP with larger I/O size

If the I/O size is > 3988, execute the commands mentioned below:

[root@host]# echo 1024 > /proc/sys/vm/nr_hugepages

[root@host]# CXGB4_SOCK_HUGE_PAGES=1 PROT=UDP wdload

<pathto>/your_application

4.1.5. Example with hpcbench/udp

The udp benchmark from the hpcbench suite can be used to show the benefits of

libcxgb4_sock. The hpcbench suite can be found at:

Source: http://hpcbench.sourceforge.net/index.html

Sample: http://hpcbench.sourceforge.net/udp.html

The nodes in this example, r9 and r10, have T5/T4 eth1 configured and the ports are connected

point-to-point.
