The box has passed a 12 hour torture test running Mprime 23.5 under 32-bit Linux... I tried to get a benchmark under 64-bit Linux but Prime95 would not run...

Code:
-bash: ./mprime: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory
Now all I have to do is put the box back together and put it into my network... I hope to complete that tonight...

I ended up going with Red Hat 9 Linux... It was just the easiest to install for me... I have ISOs burned of all the distros I listed earlier so changing to a different one wouldn't be too difficult...

Wackerbarth,

That could be a perfectly innocuous comment or a risque effort at a bad pun!

Xyzzy,

I suspected that prime95 would fail under a 64 bit OS. 32bit mode would be the only reasonable way to get it to execute. George will have to do some code work before it will run in native 64 bit.

I just got back from the ER... Apparently I have a kidney stone... All I know is I am in some serious pain... They gave me morphine and percocet so it might take me a bit longer to set stuff up... I've worked with morphine before when I was a medic, but I've never had it myself... I am very impressed with it now that I have... We're talking going from unimaginable pain to feeling quite good in less than 15 seconds...

Hopefully in the morning I'll be able to get some more work done!

That's a software problem (on OS side) because 64bit long mode has a compatibility mode where 32bit apps could run side by side with 64bit apps.

No need for recompilation - as long as one doesn't want to use the advantages of 64bit mode.

My neighbor has a long history of kidney stones. The doctor tells him to drink lots of water and avoid tea and certain leafy green vegetables because they contain oxalic acid.

He has a homemade remedy that dates back several hundred years and seems to be quite effective. He chops up about a cup of watermelon seed and brews a thick tea from them. He tries to drink at least a gallon in 8 hours. Usually that clears them up within a day or so. The last one he had was the size of a small marble so it took surgery.

I've got mine up and running now on Suse Enterprise Linux 8.2 beta 64-bit mode. Struggled with the on-board nic, which will not work.... but I put in a different nic and all seems well. Been running the seti 64bit client just to see how it runs. 2:40 for a wu or so.

Any of the developers wish to get on ?? I have a nat tunnel for ssh through my firewall direct to the box.

If you have a revision C, please run mprime on it! ;)

I'm still thinking of a way how to get a rev C Opteron w/o having to buy the top models. I hope the new revision will migrate into the lower models soon.

It's alive!

I spent close to 8 hours trying to get it to post with no keyboard, but there is no combination in the BIOS that will allow that... I suppose maybe I'll pick up a USB keyboard because I sure hate yanking the PS/2 keyboard...

Be aware that George has the right to boot everyone off if he needs to run some timings... Also be aware that everything is logged so play nice...

Don't think this is a borg opportunity either... :)

I'm not sure exactly what criteria George wants to use to allow or disallow access, but I think we'll be a bit conservative until he decides on a course of action... I suppose interested parties will contact George and he'll forward the approved people my way... (I really don't want to make decisions like that!)

We only support port 22 connections, so that means SSH, SCP and SFTP... If you need a client or a quick tutorial just let me know... Linux already has this stuff built in, but if you use Windows, here is a nice free client...

Be aware that periodically backing up your user files would be a smart move... :)

I ended up installing a WD400JB hard drive... This drive cost us $66 from Newegg... That leaves us with $925.13 in donations, $814.33 spent, and $110.80 left... I expect the CD drive will cost us around 25 bux... The hard drive we were going to use is making a high pitched squal as if the bearings are shot... It actually didn't spin up at first, so I suppose it isn't in good shape... The good news is the new drive is pretty fast...

Code:
[root@opteron root]# hdparm -Tt /dev/hda
 
/dev/hda:
Timing buffer-cache reads: 128 MB in 0.20 seconds =640.00 MB/sec
Timing buffered disk reads: 64 MB in 1.38 seconds = 46.38 MB/sec
Here's a snippit from uname...

Code:
[root@opteron root]# uname -a
Linux opteron 2.4.20-9.2 #1 Thu Apr 10 12:00:25 EDT 2003 x86_64 x86_64 x86_64 GNU/Linux
Here is some gcc info...

Code:
[root@opteron root]# gcc -v
Reading specs from /usr/lib/gcc-lib/x86_64-redhat-linux/3.2.2/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --host=x86_64-redhat-linux
Thread model: posix
gcc version 3.2.2 20030313 (Red Hat Linux 3.2.2-10)
Anyways, I'll post a picture here in a minute and later on today I'll go into a bit more detail about how it is set up...

:)

Dresdenboy,

I'm not sure what a revision C is?? But it's a brand new 1.8Ghz model.. I'll run mprime on it today, see what it does.

xyzzy, I'm out of town in Boston for the next few days, but I'll give you a call when I get back. How was the RH install ?? Taroon right?
