[Gems-users] Running benchmark occurs L1 OVERFLOW and some benckmarks halt for a long time

[huitzu shih <huitzu.shih@xxxxxxxxx>]

Dear,

I have two questions about running benchmark, and I have modified the benchmark for TM. Including TM_Workload_Setup and replace lock and unlock to BEGIN_TRANSACTION and COMMIT_TRANSACTION.

1. Recently I run btree with "ee_hybrid_pred" and 32 cores on GEMS 2.1 & Simics 3.0.30.
    The debug messages are as follows. I wait for this benchmark for more than 2 days, and it still occurs OVERFLOW. 
     I use the default set about L1,L2,memory.
    Does it run correctly? Does it normally run btree with 100000 transactions for more than two days?

2. I run benchmark barnes with "ee_base_nopred" and the following setting with 32 cores. 
   The debug messages seems normal but it halt at "16542720....." and it does not print any messages for 10 hours.
   In my opinions, I have set the instruction "setup_run_for_n_transactions", so it should stop automatically like other benchmarks . 
   But the simulator still runs. It is strange that it does not print any message after print the last line "16542720...." .
   I also have the same problem when running radiosity which is halt at "37653058...."

@transactions = 1
@dump_interval = 1
@arg_str = "512" #BODIES
@mfacet.setup_run_for_n_transactions(transactions, dump_interval)

mfacet.run_sim_command("ruby0.setparam XACT_STORE_PREDICTOR_ENTRIES 0")
