[Beowulf] Detecting binaries that are limited to an architecture?

[John Hearns]

At FOSDEM this year there was a very good presentation by Robert McLay of TACC on XALT, which tracks how
supercomputers are being used down to the level of binaries and libraries:

They use LD_PRELOAD to link in a bit of code which runs at the start of every job.
I don't think they do exactly what you want - ie to look at opcodes. But you could do worse than contact them and see if this approach could
be useful to you.
I guess though that they are recording what binaries and libraries are used  - ie the job is always  started.
You are aiming to analyse a binary and to prevent it running on the wrong architecture.
