Re: [Gems-users] Trying to run microbenchmarks/transactional/deque

[Jiří Šimša <jiri.simsa@xxxxxxxxx>]

Hello Polina,

thanks for you answer. 

ad 1) The binary is run with superuser privileges.
ad 2) When setting up the config.py I chose 4 for smt_threads. However, I am not sure if that is the correct option.

We have also tried augmenting the tm_bind_to_cabinet function with pset_info, pset_create and pset_assign to better understand what is going on. No success there.

We are running the benchmark on a sunfire/peanut machine with Solaris 10 and $num_cpus = 4.

I will be grateful for any suggestions as to how to get the deque benchmark to run. Thanks!

Most likely you just didn't assign processor ID's correctly before running the benchmark.

Hi Jiri, 

Just to be clear:

1. You are running with 4 processors, how many threads?

2. Did you make the checkpoint such that you are logged in as root?

The message you are seeing comes from calling pset_bind function. Pset_bind binds the given thread to a particular processor. In order to do that the processor number that is passed to pset_bind must be valid. You are seeing the failure message because the processor number that gets passed to pset_bind is somehow invalid.

Hope this helps.

Hello,

I am trying to get GEMS 2.1.1 + Simics 3.0.31 to run the deque transactional microbenchmark.

I followed the description at: http://pages.cs.wisc.edu/~david/courses/cs758/Fall2007/handouts/hw-logtm.html. I used different SPARC-based machine for producing the binaries and also generated my own checkpoint (with 4 processors) and set it up so that it had access to the host machine. When I run: ./deque-TM-1024ops-32bkoff-1c-4p-1t-default-EagerCD_EagerVM_Base_Pred-Perfect_-Perfect_-Perfect_-10000.sh I get the following output:

bash-3.00# ./deque 3 1024 32
binding to cabinet 1
binding to cabinet 2
binding to cabinet 3
pset_bindpset_bind: Invalid argument
pset_bind: Invalid argument: Invalid argument

Time = 2820202 nanoseconds

Could anyone explain to me the significance of the "Invalid argument"? Thanks.

Best,
