Hi,
I’m using the precompiled Splash benchmarks for M5 version 1.1 and the
SE mode. The problem is that many of these benchmarks eventually
deadlock. I have traced the problem to the synchronization functions in
alpha_tru64_process.cc. Here, all processors end up calling the
m5_cond_waitFunc() method and they all suspend. The really bad thing is
that if you simulate for a fixed number of clock cycles, it is very
difficult to see that something has gone wrong.
I’ve added the following code to the end of the m5_cond_waitFunc()
method to detect the problem:
if(process->waitList.size() == process->numCpus()){
fatal("We have a deadlock");
}
Have you seen this problem before?
I think it might be a problem with the thread library. However, I have
not been able to look into this as I do not have a working cross
compiler. Have you been able to build a cross compiler for the Splash
benchmarks and the thread libraries?
Regards,
Magnus Jahre
