<html><head></head><body>2 things to look at. First how large a chunk of data did you try to process. The first question in this FAQ<br>
<a class="moz-txt-link-freetext" href="http://www.netlib.org/benchmark/hpl/faqs.html">http://www.netlib.org/benchmark/hpl/faqs.html</a><br>
talks about setting the chunk to large hence swapping and lower numbers.<br>
<br>
Second the default 6.2 kernel does have some problems. You might want to try upgrading to a newer kernel. <br>
<br>
Other than that I would need more information about the setup of your cluster
to be of any help. (i.e. hard drive type and size. Amount of memory and type.
Network connection etc......)<br>

<pre>Hello Guys,
I have an 8 node cluster and am running Redhat Linux 6.2. I have installed
the HPLinpack benchmark and am running it. What kind of performance should I
expect? The machines are Pentium III 550 MHz. I am getting a performance of
0.79 GHz. That seems less. What can be the reasons? What should I do to
improve my performance.
I would really appreciate it.
Thanks
Mehul
