	As can be seen, the VSIPL libraries were very poor in HPL runs. Once the BLAS libraries (as tuned by ATLAS) were installed, the performance using the exact same HPL.dat file increased by 5.4 times! The next thing to do is to tune the other parameters of the dat file to see what we can get out of this machine.		As can be seen, the VSIPL libraries were very poor in HPL runs.

		+	As a contrast, running HPL in a virtual machine using VMWare on a quad core Intel Q6600 @ 2.4 Ghz, the VM only having 384mb of ram assigned to it, gave me a Gflop speed of 2.1 or so.

 * In other reports, I have seen mention that the fan on this machine was quite loud. In my experience, it is really not noticeable. Of course, the environment I have it in consists of a number of other machines that completely drown it out. Putting my ear up close to the machine, however, does elicit a slight hum, but it is nothing that would bother me. It would seem that Lemote has been listening to folks and has fixed this problem with the machine. Some of the links that support the loudness of the fan are listed here:

 ==Opening the Box==
 Opening the box to the system, you will find that there is a small manual, a power cord with a Chinese plug on one end, a power inverter, and installation CD, and the Fulong unit itself. Fortunately the power inverter's AC plug is a standard C14 socket, so any cable that you may have that ends in a C13 plug will do. Voltage input on the inverter is a standard range of 100-240V and 50-60hz, with an input amperage of 1.7A. Output is 12VDC at 4.17A. Because of this it looks like it would be a very easy unit to replace if the power inverter goes bad.
 ==HPL==
 Testing the machine with HPL requires a number of sub-programs to be installed.

 * The root account is configured with a password. There is paperwork in the box with the machine detailing what the account passwords are and all, but if you are like me and cannot read Chinese, it might be a bit hard to decipher. As such, the password for the root account by default is "loongson".
 * By default the network interface is configured for a static IP. I unfortunately deleted that portion before I got to writing this up, so I don't know what the exact IP is, but I do know it was one of the typical 192.168.0.x IP's.
