I don't know what exactly that means. I generally run it on wetware.
But I sometimes ask Hernan to run Dat3M (on his machine) over all the 
litmus tests in your repo to spot any obvious problems with variations I 
consider.
I don't think Dat3M is feature-complete with herd at the moment, just 
unbelievably faster. For example I think it ignores all flags in the cat 
files.
Oh, I just remembered that I also installed herd7 recently to make sure 
that any patches I might send in satisfy herd7 syntax requirements (I 
think you called this diagnostic driven development?), but I haven't 
used it to really run anything.

Is it too obvious that my words usually aren't backed by cold machine logic?

Best wishes,
