Someone was asking on Slashdot about cheap clustering and I wondered how much 1 Teraflop would cost in consumer hardware; the answer: just £4000 (yes I know I could have done it with just a couple of GPUs but most software still only runs on CPU). Here is what I came up with: Each node has an intel i7 2600k (approximately 100 gflops) + 8GB RAM and can be built for £380 (quick amazon search) If you have 10 Nodes you have 1 Teraflop costing £3800 leaving £200 for network hardware and hard drives for the master node (nodes are network booted) I might do this one day or maybe just a 5 node cluster.

When building consumer or commodity clusters, one of the main bottlenecks is the network. This is because the only network that people can reasonably afford is GigE as things like infiniband are way to expensive per node. SATA III now has a transfer rate of 6 GB/s so it is 6 times as fast as GigE so why is it not possible to use this as a form of communication between two or more computers. Something very similar to this is the USB network bridges you can buy (example) but they are much slower. When searching on Google the only thing I could find was this but it is only for SATA I and it only seemed to be a theory with no actual working prototypes. If I tried to do this how would I accomplish it? Could I simply plug a Male to Male SATA cable into the two computers and read and write directly to the SATA port? Can you actually directly read and write to a SATA port? On the USB network bridges there is some kind of circuit in the middle, what does this actually do and how would it be implemented for SATA?

Don't really know what you mean by this as if I unmount the share there will be nothing to chroot to but I think an easier way of doing this is to pxe boot the second computer.

I was wondering whether or not it is possible to chroot to a shared folder on computer 1 that has been mounted on computer 2. When I try to chroot it says "chroot: cannot change root directory to /foobar: Permission denied". What I am trying to do is run programs on computer 2 as if they are running on computer 1 i.e. they don't need to be installed and still write files to computer 1. If I am going about this the wrong way or there is an easier way please tell me.

If you wanted source code you should of just asked. Link to sourcecode: http://cid-425a7706bba34cb6.office.live.co...pplication1.zip

Possible problem: On computers with Windows Vista or higher, Truecrypt may have to be installed fully first.

Here is a program I made after seeing numerous reports of government workers losing unencrypted data because things like Truecrypt where to complicated for them to use. The program is made in Visual Basic (sorry everyone on Linux) and just has a password field and on OK button. It requires "truecrypt.exe" and a volume called "volume.tc" in the same directory as the program and can be hidden. This was my first proper program so please speak freely about it.

1. Yes I am on Windows with a few Linux boxes lying around 2. There is a program (I don't remember the name) that forces all network traffic through a proxy, this is the sort of thing I want. A program that forces some processing to be done on another computer

Yes but you have to install an new os for that. I want to know is there any way to do that without reinstalling

Does anyone know how you could run a program on two computers (one slave one master) so that the slaves idle cpu could be used on the master computer like the seti@home project but on a home network. I have been trying to do this as I am converting a load of DVDs into a format playable by my android tablet on my laptop and have 2-3 old computers lying around.

Google "Stoned Bootkit". Basically because the mbr isn't encrypted (even though the drive is) it can completely bypass full volume encryption and because it is based on konboot it bypasses the login as well.

A good cheap tablet is the "eken m001" but unfortunately at the moment it is only android although people have managed to port things like metasploit over to android (e.g. here). Although it doesn't have bluetooth it can be hacked to have usb ports (by wiring an ipod connector to a usb hub) and so a usb bluetooth module can be plugged in.

On most laptops there is a hardware switch that turns wifi on and off. If this is off then no amount of software can turn it on (because the circuit is physically broken) so the only way to get wifi is to turn it on. To find the switch look around the side of your laptop for a switch that has the wifi symbol or a picture of a telegraph pole transmitting something.

I need some help with learning C++; basically the problem is that even the simplest programs (like hello world) fail to compile. The code I am using is: #include <iostream> using namespace std; void main() { cout << "Hello World!" << endl; cout << "Welcome to C++ Programming" << endl; } And the errors I get from this are: C:\Users\******\Documents\Hello.c|1|iostream.h: No such file or directory| C:\Users\******\Documents\Hello.c|2|error: syntax error before "namespace"| C:\Users\******\Documents\Hello.c|2|warning: data definition has no type or storage class| C:\Users\******\Documents\Hello.c||In function `main':| C:\Users\******\Documents\Hello.c|5|error: `cout' undeclared (first use in this function)| C:\Users\******\Documents\Hello.c|5|error: (Each undeclared identifier is reported only once| C:\Users\******\Documents\Hello.c|5|error: for each function it appears in.)| C:\Users\******\Documents\Hello.c|5|error: `endl' undeclared (first use in this function)| C:\Users\******\Documents\Hello.c|4|warning: return type of 'main' is not `int'| ||=== Build finished: 6 errors, 2 warnings ===| I got the code from http://www.hitmill.com/programming/cpp/helloWorld.htm but have tried many others and all come up with similar errors. The compiler I am using is Code::Blocks with the GNU GCC Compiler because all the other compilers literally take an hour to compile a hello world program which can't be right but I don't really have a clue what I'm doing wrong. Any help would be apreciated.

What does PeToUSB actually do if you don't need it to make a BartPE USB. When I made my multipass/multiboot I couldn't get PeToUSB to work on vista and so just skipped that part and it still worked fine.
