<P><FONT SIZE=2>If this comes to the list in HTML format, I apologize in advance. I'm fighting with my !@#$&**&%%!@ e-mail client to send plain text messages as plain text without HTML.</FONT></P>
<P><FONT SIZE=2>About a little more than a month ago I mentioned some benchmarking I've been doing with Java applets that do Beowulf like processing. For those of you who forgot or are new, this was an experiment done to benchmark a Network of Workstations (NOW) cluster that runs on Java applets in standard web browsers. A complete description of the project and the software I developed for it is at <A HREF="http://www.nationalinformatics.com/GlobalNOW" TARGET="_blank">http://www.nationalinformatics.com/GlobalNOW</A>. </FONT></P>
<P><FONT SIZE=2>Well, I'm done gathering the results for the first test, which lasted a month, and they can be found here: </FONT>

<P><FONT SIZE=2>We had some really interesting results. Here's a summary:</FONT>
</P>
<P><FONT SIZE=2>One calculation is defined as the addition of two randomly generated real numbers of double word size. The algorithm that does each calculation is composed of at least 18 instructions (assignments, comparisons, etc . . . ).</FONT></P>
<P><FONT SIZE=2>The peak performance by a single workstation was 251,288 calculations per second.</FONT>
</P>
<P><FONT SIZE=2>The peak performance in a given hour was on November 29, 2000 between 10:00 AM and 10:59 AM. We had 387,310,620 calculations. Thats about 6,455,177 calculations per minute, and about 107,586 calculations per second. This translates to about 1,936,553 instructions per second. </FONT></P>
<P><FONT SIZE=2>We're certainly not breaking any speed records yet, but remember this was achieved with only </FONT>
<BR><FONT SIZE=2>7,300 visits to the web site over a period of about one month. Imagine what would happen if this were done on Yahoo! or NASA's web site.</FONT></P>
<P><FONT SIZE=2>If you're interested in trying this out yourself let me know.</FONT>
</P>
<P><FONT SIZE=2>Thanks to everyone who helped to do the benchmarking by visiting the web site!</FONT>

<BR><FONT SIZE=2>> Geneva, December 19, 2000 - STMicroelectronics (NYSE: STM) today</FONT>
<BR><FONT SIZE=2>> announced an agreement to acquire Portland Group Inc (PGI), a vendor</FONT>
<BR><FONT SIZE=2>> of compilers and software development tools to the high-performance</FONT>
<BR><FONT SIZE=2>> parallel computing market. ST will invest $17.1 million to acquire</FONT>
<BR><FONT SIZE=2>> full ownership of PGI's operations, including the product portfolio,</FONT>
<BR><FONT SIZE=2>> know-how and technologies developed by the company. Based </FONT>
<BR><FONT SIZE=2>> in Portland,</FONT>
<BR><FONT SIZE=2>> Oregon, PGI is a privately held company that has been </FONT>
<BR><FONT SIZE=2>> operating for 10</FONT>
<BR><FONT SIZE=2>> years and has world-class expertise in advanced computing</FONT>
<BR><FONT SIZE=2>> architectures and bringing parallel compiler technologies into</FONT>
<BR><FONT SIZE=2>> production on the world's fastest parallel supercomputers.</FONT>

</P>
<P><FONT SIZE=2>Where this leaves the Linux products is extremely unclear. ST seem to</FONT>
<BR><FONT SIZE=2>want the people and compiler technology for their embedded processors.</FONT>
<BR><FONT SIZE=2>The press release makes no mention at all of PGI's commodity compiler</FONT>
<BR><FONT SIZE=2>business.</FONT>
</P>
<P><FONT SIZE=2>As yet there's nothing on www.pgroup.com at all.</FONT>

<P><FONT SIZE=2>Enjoy.</FONT>
