So how many Pis can you cluster together to equal the performance of a standard i3/5/7 laptop (for non-GPU bound calculations)?

That'd be a fun experiment. If only I had disposable income :). I wonder how much heat these things produce? Could they be used to make an efficient, small cluster?

  Mount an Arduino to measure the heat which bridges into your Mathematica program... world's most efficient micro-Mathematica cluster, world's least efficient radiator circuit.

  People make clusters of them.

  You could make a cluster with them (in fact for none-mathematica uses it has been done). Efficient not even remotely the performance per unit of a Raspberry Pi just makes it not worth it (note: it's worth it if you want to simulate multi-node programming, SMPP type stuff). For example a 32 node raspberry pi machine clocked 10.9Gflops on linpack[1], 32 * 35 is $1120 (excluding switches, cabling, power supplies which would add at least another $200 or so). A single Nvidia Titan clocks ~1.5 Teraflops in double precession mode for ~$1000 (a performance per dollar rate of 137 times better). According to wikipedia[2] a cheap Sempron 145 with 3 Geforce GTX760's at $1090 has a performance of 6.771 teraflops (so over 500 times the performance of the 32 node raspbery pi) 1 http://www.zdnet.com/build-your-own-supercomputer-out-of-raspberry-pi-boards-7000015831/ http://www.zdnet.com/build-your-own-supercomputer-out-of-ras... 2 http://en.wikipedia.org/wiki/FLOPS http://en.wikipedia.org/wiki/FLOPS
