Excuse the comparison but yes...like a potato light bulb. Not the potato's best use...but doable...just like with the Pi.

this is true. run debian on an i7 and thats one os, run it on a 20-pi rack and thats 20 oses. the loss in cpu ipc would be large running on a large number of these. cool, yes. realistically useful, no.

....and I repeat, you need more than a 100Mb USB-bussed ethernet NIC if you really plan on doing any practical distributed processing. Else you'd be better off with a multi-core CPU sharing one single system RAM pool.

Now this is where I'm confused. I've never really looked into networking.

1) Why do you go on about gigabit etc. when I only have a 20mbit connection?

An internet network connection and local area network connection are 2 different beasts. Your 20mbit connection is the speed your ISP limits you to, your router and computers are probably capable of Gigabit speeds, if not they can certainly do 100mbit. The amount of data being processed in a cluster computing environment would require a high speed network such as Gigabit or 10Gbit as not to bottleneck the performance of the cluster.

^ that

I just want to add that it's not just bandwidth that matters, but latency is important too. From what I've read, the performance of the 100Mb NIC on the Pi is pretty poor due to it sharing the USB bus.

Thanks for clearing that up :Thumb:

The Pi was exciting at first but now it's like why put an energy efficient SoC out there that needs to be hooked up to traditional peripherals? It's already being outsold by cheaper Chinese ARMv7 SoCs that usually come in a proper package (i.e. with a touchscreen and Android). Props to making a quick buck off a novelty but it's falling off the embedded systems bandwagon as fast as it jumped onto it. I wonder if the guys porting Linux distros to ARM are facepalming and handing their resumés to Google yet tongue.gif
