1) Message boards : Number crunching : ARM Devices (Message 1159)

Would it be possible to build this application for a generic ARM Linux platforms like arm-unknown-linux-gnueabi (without hardware support for floating-point, like ARMv5) and arm-unknown-linux-gnueabihf (with support for floating-point, like ARMv6)?

Though ARM is not a high-performance processor by today's standards, it may be as fast as the typical PC of a few years ago and comparable to a current Intel Atom.

Other projects like Enigma, OProject, QCN, Radioactive, Yoyo and WUProp already provide an application for such platforms.

I've helped out other projects getting the applications built and tested, as can be seen here. Please, let me know if I can help.

TIA

GNU Fortran, I don't think that there is so much difference in the assembly code quality on different operating systems.

That's true. I suppose that GNU Fortran from MinGW was used, which I'm not that familiar with, but it's possible that the difference then lies in the different math libraries available in each OS. I can only speculate...

Keep in mind that thought the hosts may be comparable, possibly different compilers were used to build the application for each OS. If this is the case, then performance can indeed vary wildly.
