A very good paper about building HPC clusters with FreeBSD:

"Building a High-performance Computing Cluster Using FreeBSD"

http://people.freebsd.org/~brooks/papers/bsdcon2003/

The author talked about hardware issues: KVM, BIOS redirection, CPU
choices; and then talked about why he chose FreeBSD instead of Linux...
he also did the port of GridEngine (SGE) to FreeBSD.

Anyone tried to setup HPC clusters with *BSD??

Hi,

Not quite the same as an HPC cluster, but take
a look at the University of Utah's Emulab:

http://www.emulab.net

It is heavily based on FreeBSD (i.e. makes use of FreeBSD routing,
Dummynet, etc.).  The Emulab is a remotely accessible testbed
that researchers can use to conduct network experiments.  It
consists of about 200 PC nodes.  The same company that 
Brooks works for (Aerospace), has apparently set up
an internal testbed based on the Emulab software developed at Utah.

I use the Emulab every day as party of my research work at
BBN, and it is an excellent facility.

I have a 30 node NetBSD/i386 cluster, and just recently created the
tech-cluster@netbsd.org mailing list.  Some people are working on a port
of SGE to NetBSD, too.  I hope to expand the awareness of NetBSD in
particular for cluster usage in the near future.

We (my department, but mostly different people then Fellowship) have a
small 10-node setup (though each node does have 6 gigabit ports :-). I
think we're aiming to upgrade to around 48 nodes in the next year.

Our HPC cluster is currently pretty close to what's described in the
paper, though we are up to 160 nodes and we're adding rack space for
another 192 this year.

The short version of my take on which OS to run on your cluster is
that so long as it runs the apps you need, the best OS is one you know
how to admin well since that's most of the work.  I've spent a few
weeks here and there porting applictions or improving their ports, but
by and large, most key systems are already ported to the major UNIX
platforms.  The free MPI implemntations work on just about anything, the
base Ganglia metrics work nearly everywhere (FreeBSD and Linux are at
feature parity in the upcoming release), and SGE works on a wide range
of platforms.  On an amusing note, we were the launch customer for Grid
Mathematica despite not running a supported OS because the Linux version
runs just fine on FreeBSD.

Hi,

	We have a 64 node cluster entire based on FreeBSD 5.1 for high 
performance computing at the Federal University of Alagoas 
(http://www.typhon.ufal.br). It has 36 Dell Pentium IV 2.4GHz nodes and 
36 Gateway Atlhon 1GHz using a fast-ethernet network (the peak 
performance for Dell machines, measured with xhpl, is 37 Gflops).
	Applications may use MPI for inter-process communication. For the 
cluster management we are testing the Ganglia 
(http://ganglia.sourceforge.net) and for scheduling the Maui 
(http://supercluster.org/maui).

Dear friend,

It is with heartfelt hope that I write to seek your co-operation and assistance
in the context stated below:

May I first introduce myself: I am Senator Luisa Pimentel Estrada,the first
wife of Joseph Ejercito Estrada(former head of state and President of Philippines)
who is presently held in detention in a hospital outside manilla,Philippines.
I got your contact from the internet during the course of my search for
a reliable foreigner who will assist me in receiving the sum of US$17Million
secretly deposited in my favour by my Husband.

This money was kept with a Security Company in Amsterdam and I have all
documents with me as of when it was deposited in a Security Vault for safe
keeping. We have been deliberating on how to invest this fund abroad in
a confidential manner until we came to a conclusion to use it to buy estates
and part of it will be used for non-speculative investments in your country.


However,the current administration of Gloria Arroyo(The President of Philippines)
is seeking the death of my husband.In pursuit of this vendetta,the present
Government have resolved to freeze all known assets of Joseph Ejercito Estrada
including properties at home and abroad and are presently embarking on to
seize the various bank accounts of my Husband in Switzerland,UK and Australia.
In fact, the attack on our family (The Estrada's) is so devastated to an
extent of seizing our travelling passport,family accounts,trying some members
of our family in court for offences allegedly committed by my Husband and
even restrict us from seeing my husband.


My son was released from detention on the agreement to refund $1.5 million
to the Government of Philippines allegedly stolen by my Husband.
You can find this on;
<http://latelinenews.com/ps/english/29432.shtml>
<http://www.time.com/time/asia/magazine/2001/0129/cover1.html>

We are not ready to comply to this as most of the family assets and bank
accounts abroad have been Frozen by the Arroyo regime. In view of this grevious
threat to our Economic and personal survival, our family trustee have secretly
protected the deposit, you are to assits us travelling to Amsterdam to lay
claims of the consignment with the aid of all legal documents that will
be forwarded to you as time goes on.

In the meantime,there is a travelling embargo on the family members and
our local accounts are seized as well as our telephone lines have been bugged.For
this reason,telephone conversation will not be an ideal means of communication
because our calls will be recorded.We are currently being catered for by
the Government of Philippines in other to monitor and control our financial
activities. We cannot be held responsible for the sins of my Husband. In
view of this plight, I expect you to be trustworthy and kind enough to respond
to this distressed call to save our family from a hopeless future.And if
you agree to help, we shall discuss the disbursement ratio in our next
correspondence after we have been acquainted.

I look forward to your quick response while thanking you for your co-operation.
In view of all above details, I request you to keep this letter and co-operation
highly confidential even if you are not interested.

Best wishes,

Senator Luisa Pimentel Estrada.

NB:
Please note that email correspondence will be safer due to the fact that
all our phone lines have been bugged.

If you are intreasted in this proposal please send all further email correspondence
to l_p_estrada@rediffmail.com
