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:

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. ##################################################################################### Scanned by MailMarshal - M86 Security's comprehensive email content security solution. ##################################################################################### Any views or opinions presented in this email are solely those of the author and do not necessarily represent those of the company.
