Hi all,
I encounter an infinte loop when running a multi-threaded program on a
multicore simulator with a control processor and 4 slave cores. This
atomic_add, as printed in the trace, seems to keep accessing the cache forever
and I have to aborted the simulation manually. Any clues on it?
Thanks a lot!
