Re: [ptp-dev] How does SDM do the scalability problem
|
I'm not sure. It sounded to me like you could use it as a stand-
alone product or integrated into a whiz-bam gizmo that did runtime
parallel instrumentation (the latter using MRNet).
Cheers,

I agree that supporting dyninst would be desirable. I don't think
MRNet is needed for this though, is it?

Yes, it was a heavy sells job. However, there may be synergy with
dyninst. It would be a lot easier to track down hot-spots in code
if you were able to do dynamic instrumentation, rather that
static. The user doesn't really want to stop and recompile code
to add loop level instrumentation, for example. It would be much
cleaner to stop at a break point in the debugger, dynamically
modify the binary to change instrumentation, and continue execution.

I'm talking with Bart Miller and he asked how the debugger
scales. He wonders if MRNet (multicast reduction network might
be applicable).
There are several papers in the middleware section from the
address below that sound interesting in relation to debugging.
