<a name="introduction"></a>
<h2>Introduction</h2>
<p>The netperf cluster provides a multi-node, SMP-capable, network
functionality and performance test capability for the <a
href="../../">FreeBSD Project</a>, supporting a variety of on-going
sub-projects including the <a href="./index.html">netperf project</a>,
and on-going work on
high performance threading. The cluster is available on a check out
basis for developers, who must request accounts be created by
contacting one of the <a href="#admins">netperf cluster admins</a>.
The cluster includes both 1gbps and 10gbps test segments, with
network hardware from a number of vendors.</p>
<a name="donors"></a>
<h2>Donors</h2>
<p>The netperf cluster was made possible through the generous donation
of a number of organizations, including:</p>
<ul>
<li><p><a href="http://www.sentex.ca/">Sentex Data Communications</a>,
who not only host the complete cluster, provide front-end build
system, several test systems, and the management infrastructure
(remote power, serial console, network switch, etc), but also appear
to be endlessly willing to help configure, reconfigure, and
troubleshoot at almost any time of day or night.</p></li>
<li><p><a href="http://www.freebsdsystems.com/">FreeBSD Systems</a>,
who through a generous matching grant with the FreeBSD Foundation,
provide the majority of testing hardware used in the cluster,
including three dual-Xeon test systems.</p></li>
<li><p>The <a href="http://www.FreeBSDFoundation.org/">FreeBSD
Foundation</a>, who provided a matching grant for the purposes of
purchasing testing hardware, as well as taking ownership of hardware,
offering tax receipts to donors in its role as a non-profit, and
participating in cluster planning.</p></li>
<li><p><a href="http://www.ironport.com">IronPort Systems</a>, who have
donated a test server.</p></li>
<li><p><a href="http://www.ixsystems.com/">iXsystems</a>, who have
donated several test servers.</p></li>
<li><p><a href="http://www.google.com/">Google, Inc.</a>, who have
donated two test servers.</p></li>
<li><p><a href="http://www.cisco.com/">Cisco, Inc.</a>, who have
donated a 10gbps switch.</p></li>
<li><p><a href="http://www.chelsio.com/">Chelsio Communications</a>,
who have donated two 10gbps network cards.</p></li>
<li><p><a href="http://www.myricom.com/">Myricom, Inc.</a>, who have
donated two 10gbps network cards.</p></li>
<li><p><a href="http://www.intel.com/">Intel Corporation</a>, who
have donated two 10gbps network cards.</p></li>
<li><p><a href="http://www.meinberg-usa.com/">Meinberg</a>, who
have donated a LANTIME M600 IEEE 1588 Grandmaster Clock.</p></li>
<li><p>&a.gnn;, who has donated a quad-core AMD test
system.</p></li>
<li><p>&a.rwatson;, who has donated a dual-CPU PIII system and a
Portmaster terminal server.</p></li>
</ul>
<p>Donations to support the netperf cluster have an immediate and
substantial impact on the success of a number of on-going performance
projects, providing access to high-end hardware to a large number of
developers. If you or your company are interested in helping to
support continued development of the netperf cluster as a resource for
FreeBSD development, please contact the <a href="#admins">netperf
cluster admins</a>.</p>
<a name="admins"></a>
<h2>Netperf Cluster Admins</h2>
<p>The FreeBSD netperf cluster is managed by a small team of
developer/administrators to support SMP development and performance
testing on high-end hardware. If you have any questions, including
questions about access to the cluster as a developer, or about possible
future donations of testing hardware, please feel free to contact them
via netperf-admin at FreeBSD.org.</p>
<a name="resources"></a>
<h2>Netperf Cluster Resources</h2>
<p>The Netperf cluster consists of several systems interconnected using a
management network, as well as individual back-to-back gigabit ethernet
links for a test network. The following systems are available as
testing resources on a check-out basis:</p>
<ul>
<li><p><b>zoo.FreeBSD.org</b> is the front-end build and management
system. This system was donated by Sentex Communications.</p></li>
<li><p><b>elephant</b> is a dual-PIII 800MHz system with ATA disk
subsystem.</p></li>
<li><p><b>orangutan</b> is a dual-Xeon 2GHz system equipped with an
Adaptec SCSI RAID array. This system was donated by IronPort
Systems.</p></li>
<li><p><b>tiger-1</b>, <b>tiger-2</b>, and <b>tiger-3</b> are a set of
interconnected, matching dual-Xeon 3GHz systems with ATA disk
subsystems. Each has four if_em network interfaces, and these are
interconnected so that various topologies can be created.
These systems were donated by FreeBSD Systems and the FreeBSD
Foundation.</p></li>
<li><p><b>cheetah</b> is a dual core Opteron 270 system with two
2GHz CPUs each with two cores using a Tyan K8S Pro (S2882)
motherboard. The machine identifies as a quad processor machine
in dmesg. The system has SATA disk, 2GB of RAM, 1GB for each
processor, and 5 ethernet ports. fxp0 is the management port
and em0, em1, bge0 and bge1 are gigE interfaces which will
eventually connect cheetah to elephant and orangutan. This system
was donated by George Neville-Neil.</p></li>
<li><p><b>hippo</b> is a quad-processor Pentium III 500MHz system
with 50GB RAID array, donated by Sentex Communications.</p></li>
<li><p><b>camel</b> is a dual core Pentium D 3.0Ghz SMP system
with four SATA disks and two hardware crypto devices, donated by
Sentex Communications.</p></li>
<li><p><b>interlope</b> is a Celeron 2.5GHz system with two SATA
disks running SUN Solaris 10, donated by
Sentex Communications.</p></li>
<li><p><b>apc2</b>, <b>apc3</b>, and <b>apc4</b> are the remote power
consoles for the test network. These systems were donated by
Sentex Communications.</p></li>
<li><p><b>leopard1</b>, <b>leopard2</b>, and <b>leopard3</b> are
dual-core Intel systems hooked up to the 10gbps test cluster,
and use Chelsio and Myricom 10gbps cards. These systems were
donated by iXsystems.</p></li>
<li><p><b>hydra1</b> and <b>hydra2</b> are 8-core Intel systems
hooked up to the 10gbps test cluster. These systems were donated
by Google and the FreeBSD Foundation.</p></li>
</ul>
<p>The current serial port and network configuration of test systems, as
well as password information, can be found in /etc/motd on zoo. We
are currently interested in adding amd64 and em64t hardware to the
cluster.</p>
<a name="procedures"></a>
<h2>Netperf Cluster Procedures</h2>
<p>As the netperf cluster is a centrally managed and shared resource,
understanding and consistent following of its procedures is important.
In particular, following of the procedures makes it easier for
developers to have reasonable expectations about the configuration of
systems in the cluster, as well as to avoid treading on each others
toes.</p>
<p>Pointers and documentation on Netperf Cluster procedures can be found
on the <a href="http://wiki.freebsd.org/NetperfClusterPointers">
Netperf Cluster Pointers</a> page on the FreeBSD wiki.
<a name="notes"></a>
<h2>Current Configuration Notes and News</h2>
<p>A few hopefully up-to-date configuration notes that may be relevant

Cluster Pointers</a> wiki page has been set up documenting procedures
