Paul ,

thanks for the corrections below (Hypertransport), I mistook the word ;-o.

I also agree with you that the cooling SHOULD be same for 246-252 , but my
experience shows me that its not.

The Zalman most certainly qualifies for all CPUs here ;-) (its one of the
few around) , but its not necessarily small ;-)

As for the Power Supplies (PS). I tried everything from 400W to 550W and
came to the conclusion that mostly 400W is fully acceptable for most

Re: Dupal Opteron on Sarge

2005-09-19 Thread valentin_nils
O.K I guess I have to take the risk that Lord Sauron will flame me for
what I say next ;-)

I would rather recommend you a 2xCPU MB instead of a single CPU MB
You will easily find many 2xCPU MB out there and you may want to consider
the following:

- most have only 32 bit PCI slots, look for 64 bit PCI slots and the max
bus speed (133mhz)
- server boards come (optional) with onboard scsi cards
- you may still find additionally 4xSATA & IDE on the same MB
- (optional) SCSI raid card
- (optional) server admin card

If you take this all into conclusion you will probably opt for the
S2882UG3NR or a similar board from another maker
http://www.newegg.com/Product/Product.asp?Item=N82E16813151151 *no scsi
http://www.newegg.com/Product/Product.asp?Item=N82E16813151152 * with scsi

Note the scsi raid card socket (option), white and in the middle left)

Having the 64 bit pci bus also allows you to navigate real HEAVY loads
between scsi discs and the CPU & Memory.

Regarding CPU I would probably choose the 246 or 248 ($240-310) which are
slightly cheaper than the 252 and, lets face it, the CPU speed alone wont
really change so much on the systems performance.

http://www.newegg.com/Product/Product.asp?Item=N82E16819103412
http://www.newegg.com/Product/Product.asp?Item=N82E16819103433

Another concern is the heat those CPU beasts produce (90W each). You may
want to find a cooler solution which doesnt grill you or the CPU and also
doesnt make you death. (I am sitting next to such a beast right now ;-)

Most cooling systems go up to the 246 or 248. Finding one for the 252
might be difficult. I had a hard time finding a cooler which would do his
job for the 248 while still allowing me to hear my own voice ;-).

I would invest the saved money (compared to the 252) into Memory or SCSI
and use the SATA for a backup solution. I prefer SCSI, as for me it has
shown to be reliable in the long run and still outperforms most SATA/IDE
setups.

Note that 2xCPU systems are not twice as fast as single CPU systems. The
SMP setup does have a bit of a overhead on your OS, so expect something
like 0,8x the speed of a single CPU system.

What the 2xCPU system gives you however, is the ability to handle heavy
load. It can handle obviously more requests than a single CPU system. It
will also take advantage of the hyperthreading bus *communication bus
between the CPUs.
This means that CPU1 can *borrow Memory from CPU2 if it is required for an
application.

For the case I would choose the CM Stacker. It does Unfortunately not
offer the redundant PS, but you can put 2x PS from the maker of your
choice. It wont be hot swabable, you will have to switch the plugs
yourself.
http://www.newegg.com/Product/Product.asp?Item=N82E1689042

The design is also quite appealing I believe. If you do opt for the CM
Stacker make sure to get the Optional Cross floor fan.
http://www.newegg.com/Product/Product.asp?Item=N82E16800887011
It will make sure to get the heat out of the case, and that silently.

If you prefer to show off the case, there is also a sie window available
http://www.newegg.com/Product/Product.asp?Item=N82E16811999760

I hope that I could make some valid points to make your decision easier
for your next system.

The system above is more expensive than "Lord Saurons" setup but it adds a
lot of options and is really a sound system (not to say a beast ;-)

I usually buy the parts not all in one go, but as required.

Newegg as suggested by "Lord Sauron" does give a good service and I can
back him up with that.

I currently have 2 Opteron systems online which should be accessable for
the public.

1) 203.143.127.108
2) 203.143.127.98 (testing)
3) 203.143.127.99 (from October)

Do you have the possibility to take an opteron system for a testride ?
(You might find that some shops might let you try a system)

Sure. I am glad you asked ;-) You may find some applications (mostly
commercial) which are for now only available as 32 bit versions.

F.e. smaller  "Hosting" companies have to consider this when using from
the shelf software - (the bigger ones compile it themselves). So what I am
trying to say is. You "may" have a specific application which is not
available as a 64 bit version yet.

If you consider running MySQL on the Opteron then you are in VERY good
hands *consult the mysql mailing list. There is enough info to keep you
reading for a month or so.

If you want to do DTP than you just wasted your money ;-).

In order to give a better answer you should consider giving MUCH more
details (MB, Memory HDD interface etc).

F.e. I am using some of the the Tyan S2882UG3NR with 2-6GB Memory.

Which probably brings us to the next question.

Which HDD interface will you be using ?

Note that almost all Sata controllers are software based *except 3Com +
(one more I forgot).

This means that you will basically use the opensource driver when you
consider SATA.

I also tried Suse 9.2 *which is know a bit dated, which basically gave me
the best performance so far.

However for other reasons I decided that Debian is better for my needs and
future compatibility *ugrading etc.

If you are just after speed & power you may as well decide to wait for the
dual core CPUs to arrive.

One thing that is commonly reported and that I can also confirm is that
the workload on Opteron systems is usually quite low, even when running a
few tasks in the background. This is why Hosting companies like opteron
systems '=).

I hope that I could make a few valid points which can help you make a
decision. If you can give a few more details than I might be able to make
a more specific reply.

You may also be interested in some of my private scriples & notes which
are publicly available:

http://www.be-known-online.com/modules/newbb/viewforum.php?forum=113

>>Choose "AMD Opteron 64 bit"
>>Page seems to be empty, so from the dropdown menu choose "From the
beginning"

You should get some installation descriptons for Opteron based systems.

There used to be more info, however a harddisc crash sorted that out ;-).
I am still rebuilding the site.

Re: Mixing CPU's

2005-07-23 Thread valentin_nils
Hi Nathan,

May I ask what is the purpose of the original question ?

Do I understand correctly that you want to mix a single and a double CPU,
perhaps even a quad or 8-way Opteron CPU in the same system ?

Do you understand that f.e. the 2 way CPUs have an extra "Bus" between
them to speed up communication and share memory to the other CPU.
In 4 and 8-way CPUs you will find 3 of those extra "Buses".

These means f.e. that in a 4-way setup you can share the memory between
those CPUs, processes etc. according to your needs.

I believe that mixing up different CPU types and /or speeds is basically
like putting for different wheels on your car and see how far you can go
with them ;-).

Does that make things clearer ?

I am not sure yet if your background is to make "a one size fits all
computer" or you just have nothing to do. Anyway, either way good luck ;-)

Best regards

Nils Valentin

Re: Installation on SATA drive

2005-07-16 Thread valentin_nils
Hi Chetan,

You would need to know which controller is accessing the sata drive. I am
sure the drive itself is not the problem ;-).

F.e I am using  a Sil 3114 (Silicon Image). You can start Knoppix and see
with commands like "lspci" which controller you have.

Re: Debian/Ubuntu/Redhat which is better for heavy duty computations?

2005-07-01 Thread valentin_nils
I can backup Thomas that debian is typically a version behind BUT
rockstable like nothing else.

Ubuntu seems faster, but (unfortuntaley) their packages are not always
compatible with debian ones. They make their own package versions (same
like Suse/Novell, Redhat etc.). That might not be an issue for you, for me
that was a concern. F.e their Python version is not compatible with the
debian one.

Where are all the amd64 mirrors gone ?

2005-05-20 Thread valentin_nils
Hi anybody on the list,

I tried to update my debian (AMD64) version.

However today I started getting "Couldnt stat source package..." messages.

So I all except one (last one) dont seem to be working anymore.

deb http://debian-amd64.alioth.debian.org/pure64 sid main
deb http://bach.hpc2n.umu.se/pure64 sid main
deb http://bytekeeper.as28747.net/amd64/alioth/pure64 sid main

deb http://mirror.phy.bnl.gov/debian-amd64/ sid main

This are the servers I planned on using. Note that only the last one is
working right now !!

Does anybody have similar issues or is that just me ?

Thanks Paul,

current smp kernel debian package name ?

Re: AMD64 Question

Hello Simon,

I am using the Tyan S2882 (2x Opteron) with Debian sid (64bit).
The Debian system is running way more stable than Suse 9.2 Pro which I
also did install (Dual boot) for testing prupose.

Suse (Novell) did include a lot of obvious bugs in the current release
which is a shame for their Image really.

I trust that the Debian support for your mentioned hardware is stable
enough, but Ima unable to confirm that.

I made several installation reports on my personal homepage feel free to
dive in and have a look around.

While its not a direct answer to your question, I hope that you find some
useful info in the reports.
