Original Helmer + your work inspired me...Nice work!<br />Original Helmer + your work inspired me to create my own cluster ...<br />4 x Q6700 (2x 2 vertical stack) overclocked to 3 GHz in a 2U server chassis powered by 4x250W seasonic PSU. Total idle load at wall = 240W. 4x320GB HDD. MAY be possible to fit 6 motherboards in chassis if trim excess PSU cabling and re-orientate LAN cables (certainly possible if use mini-itx mobos). 2x 12cm + 4x8cm fans + low-profile shuriken coolers keep things cool enough it seems. Using Ubuntu desktop but run on separate windows XP box and check things using VNCViewer. I'm a python fan so use ipython to run cross-platform plus I use code::blocks as cross-platform c++ IDE + SWIG.<br />I also do GPU programming using CUDA on a single 9800GX2 when the problem fits the more complicated programming requirements of the GPU.<br />Right now I'm looking to increase size of cluster and looking at most cost effective solution. Looked at core i5/i7 with 8 threads but cost of mobo +CPU and corresponding performance don't (to me) compare with that of s775 + Q9550 + overclocking (if necessary). Fitting all the hardware into an appropriate chassis led me back to your posts.<br /><br />Anyway, I hope you have as much fun as I have with all this computing power!

It's not doable with all Java programs (http://gcc.gnu.org/onlinedocs/gcj/Limitations.html#Limitations), but it's worth a try.<br /><br />It would make your program as fast and memory efficient (or slow and memory hungry, compared to a real C, not to mention assembler :^) as if it was written in C++ with a GC and compiled with gcc (you have the same (optimization) options as in gcc, gcj is just a front end).<br /><br />And, as always, if you need even more speed/memory improvements you could use <b>strip</b> to remove unneeded (debugging) symbols from the binaries. It doesn't usually improve the speed much, but it do shrink the size of the executable considerably.<br /><br />I have only done this in Mac OS 10.3 on an iBook G4.
