x86 trace generator problem

[Yi-Chien Sung]

Hi all

I got some problem when i use x86 trace generator.

After i install the x86 trace generator and i want to test it, i got some problem.

I copy the bin  binary to the folder "obj-intel64"

and i enter the command  "./pin -t ./trace_generator.so -- /bin/ls " and it has a message

 "./pin: line 52: /home/thousand/nmacsim/macsim-1.1/tools/x86_trace_generator/obj-intel64/./ia32/bin/pinbin: No such file or directory"

then i add the PATH in  the bashrc file

 "export PATH=$PATH:/home/thousand/nmacsim/macsim-1.1/tools/pin-2.10-45467-gcc.3.4.6-ia32_intel64-linux"

and enter " pin -t ./trace_generator.so -- /bin/ls"

it got some problem

"pin -t ./trace_generator.so -- /bin/ls

Killed

E:Attach to pid 1272 failed.

E:  The Operating System configuration prevents Pin from using the default (parent) injection mode.

E:  To resolve this, either execute the following (as root):

E:  $ echo 0 > /proc/sys/kernel/yama/ptrace_scope

E:  Or use the "-injection child" option.

E:  For more information, regarding child injection, see Injection section in the Pin User Manual.

E:"

Anyone come acorss this problem?

Thanks,

Yi-Chien

Hi Yi-Chien,

You can follow the message from PIN execution.

That will solve your problem.

su -

$ echo 0 > /proc/sys/kernel/yama/ptrace_scope

Thanks,

Jaekyu

Dear Jaekyu:

thank you for answering my problem.

now i can generate *.raw and *.txt, but i have some problem in the "trace.txt"

i enter the command

" pin -t trace_generator.so -thread 4 -- /home/thousand/nmacsim/macsim-1.1/tools/x86_trace_generator/obj-intel64/test"

Why trace.txt content like that:

1 x86

0 0

not like that

8 x86

0

1

2

.

.

7

really appreciate that you solve my problem.

thanks,

Yi-Chien

Applee, 

Could you describe your problem? 

The initial Yi-Chien’s problem was due to missing 32-bit linux libraries.

Hi Hyesoon,

     I ran the following command before.

  pin -injection child -t ~/trace_generator.so -max 100000000 -tracename bzip2_th2_10x8 -thread 2 -- ./bzip2_base.amd64-m64-gcc43-nn  

    

     But i guess i have found the mistake, after i read the source code of the trace generator.  It can generate traces for multiple threads, only when the application is multi-threaded. However the SPEC2006 benchmark  applications are not multi-threaded.

     And i change a benchmark suite, it can work.

     Thanks for your time,

      Applee Lee

For bzip2 or other spec benchmarks, you don’t need to provide “-thread 2” option. In that case it will generate just a trace from a single thread.
