+% NUMA
+\overlays{3}{
+\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}
+\end{slide}}
+
+% Beowulf
+\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!
+\item Linux
+\end{itemstep}
+\end{slide}}
+
+% MPI
+\overlays{4}{
+\begin{slide}{Message Passing Interface aka. MPI}
+\begin{itemstep}
+% MPI is an standard
+\item A standard
+% MPI was designed for high performance on both massively parallel machines and on workstation clusters.
+\item Designed for high performance
+%  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
+\item 130 function
+\end{itemstep}
+\end{slide}}
+
+% PVM
+\overlays{1}{
+\begin{slide}{Parallel Virtual Machine aka. PVM}
+% I won't have enough time to talk and demo PVM...oh well
+\begin{itemstep}
+% PVM does a similar thing as MPI, but a little differently
+% I don't have much to say about it except that it has 38 functions, and works well for many people. RTFM
+\item 38 functions
+\end{itemstep}
+\end{slide}}
+
+% OM
+\overlays{3}{
+\begin{slide}{OpenMosix}
+% openMosix is a kernel extension for SSI clustering.
+\begin{itemstep}
+\item Single System Image clustering
+% spawn a process anywhere, and it will migrate to the best node available => load balancing
+\item Automatic process migration
+%
+\item Easy to set up
+% not in my opionion
+\end{itemstep}

+% HW: uncluterring of cables
+\overlays{3}{
+\begin{slide}{What a mess!}
+% 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
+\item Document
+\end{itemstep}

+% Let's get dirty
+\overlays{8}{
+\begin{slide}{Let's get dirty..}
+\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)
+\end{itemstep}
