[Gems-users] Barrier_breaking

[wyhsdkd <wyhsdkd@xxxxxxx>]

Hi,

I run the deque microbenchmark on logTM.The configuraion is

4 processors,g_procs_per_chip=4,g_num_L2_banks=4,

NoC:HIERACHICAL_SWITCH network,

xact_conflict_res:timestamp

xact_eager_cd:true.

when I run "./deque_TM 3 12 64",it works fine,but when executes 

"End_workload_transaction

}

Barrier_breaking(&local_sense,myid,gm.num_threads);"(see in deque.c)

I find the output result,only one thread prints "

BEGIN BARRIER",another two donnot,after a short while,the serengeti machine

shows ! "segmentation fault-core dumped".

I use "gdb -c core " and "where" to look for the error,but I get the following information:

program terminated with signal 4,illegal instruction.

[new process 66811]

#0 0x0009eec0 in ??()

I donnot know what's the meaning.Could anyone help me ?Thanks in advance!
