In one program, an instruction X is stuck and nothing else can go through until the instruction X is unstuck, e.g. when the piece of data from the memory arrives...
I investigated this a bit, and it turns out to implement TMA_BACKEND, TMA_BE_MEMORY and TMA_BE_CORE, we would not about 8 counters, so it is not possible to do it now....
I would like the described feature for both start-end measurements and instrumented code. It should just print RDTSC counter and elapsed time. Is this feasible?
Maybe you should introduce a new group called `BASIC` in likwid-perfctr that exists on all x86-64 processors? I need the time for the Marker API as well, since the runtime...
No, it doesn't happen with shorter running times. The first time it happens when the program is running for 13s. Is there any way to workaround it?
In the case of a 13 second run, the code enter and leaves the segment 32 times, so it is less than a second. Does likwid initializes those counters to...
So essentially they are unusable for any serious measurement taking more than a second :(
Thanks for the answer. One more question. is it possible to create a system with e.g. one main co and several slave co, such as, when aco_yield is called, the...
Hi Tom! I could try doing it, I use LIKWID a lot and it is a very useful piece of software to me. Can you give me some estimate how...
Wow, thanks a lot! I am simply not that fluent in highway to be able to write such a thing. The documentation is good, but I was still missing a...
