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

[BYONG WU CHONG <bernard.chong@xxxxxxxx>]

Hi, Huizu

 

I wonder about that, too. Can someone answer this question for us?

Is it possible to run two or more TM benchmarks at once?

 

As far as I know, this would be quite error prone if you want to run two processes. Because,

1.       We have to synchronize all the threads in different processes to register before the activation of Ruby.

2.       Thread registration function could be bounded to a single process.

3.       Other unknown factors.

I could be wrong, but it seems not so feasible on GEMS.

 

If I were you I would try merging two programs into one. It would be painful but it could be more feasible solution.

Could I run two different benchmarks at the same time?
I got the information after it OVERFLOW

15 XACT CONSISTENCY CHECKER: FAILED 0x[0xd81699c0, line 0xd81699c0] ACCESS TYPE: LD IN WRITE SET OF 3 PC [0x1188e8c, line 0x1188e80] RANDOM_SEED 65537

Thanks for help.!!

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")
