-\begin{slide}{NonUniform Memory Access}
-% Altix 3000 uses special hardware to connect the nodes into one "computer." 
-If you have quite a bit of money to spend, you might want to consider one of these with:
-\begin{itemstep}
-% yes, that's GigaBytes
-\item 6.4 GB/s interconnect
-% quite a bit of memory
-\item 4GB - 8TB of RAM
-% what good is hardware, when there is no software? 
-\item Linux
-% you need at least 4 zeros in the pricetag, more likely to have 5
-\item Damn expensive!
-\end{itemstep}

-\overlays{3}{
-\begin{slide}{Beowulf}
-%\epsfig{file=./beowulf.eps}
-% Are you too poor to spend quarter million on a computer? Don't worry!
-If you don't have that much money, try Beowulf cluster type.
-\begin{itemstep}
-% you can use hardware you have already at home! (point out the NYC court computers)
-\item Use any old hardware
-% Ok, maybe you think that you should spend some money
-\item Use any new hardware
-% And here we go again, need software? Get Linux!

-%  MPI is widely available, with both free available and vendor-supplied implementations. A number of MPI home pages are available.
-\item Widely available
-% for what it's worth, MPI has 130 functions

-% openMosix is a kernel extension for SSI clustering.
-\begin{itemstep}

-% spawn a process anywhere, and it will migrate to the best node available => load balancing
-\item Automatic process migration

-% Now that you have spend thousands of dollars on computers and miles of cables, what can you do to make it neater?
-What am I supposed to do?
-\begin{itemstep}
-% you won't like this, but it works
-\item Don't look
-% organize the cables, have networking cables run in "channels"
-\item Organize
-% you might want to write everything down, since a cluster can get large and you usually set it up and leave it alone for a looong time

-\begin{itemstep}
-% Debian is a good choice, this is very simple
-\item Install Linux
-% really any DNS server will do, but bind is know to be good
-\item Install bind9
-% DHCP gives the disk-less-nodes IPs and info on how to boot
-\item Install dhcpd
-% tftp gives the nodes a way to get a copy of the kernel
-\item Install tftpd
-% mknbi (debian) allows you to create the etherboot kernel images
-\item Install mknbi
-% NFS for root on NFS
-\item Install NFS
-% you need to create a root structure for each node
-\item Make / for nodes
-% if you don't have a network bootable box, make an etherboot floppy/cd
-\item Make boot floppy (optional)
