sniper-4.0 problem while running python scripts

[Francesco]

Hello,

I am having an error when launching any of the scripts for the new version of SNIPER. I did not get this error with the previous version
It seems there is some conflict when importing 'sim'

here is an example:

$ ./run-sniper -p parsec-dedup  -i test -n 4 -c gainestown -d prova -g perf_model/core/frequency=1.60 -s powertrace
[PARSEC] Benchmarks to run:  dedup

any suggestion?
Thank you

Francesco,

It looks like you have an old version of Python for some reason. I just tried a test example, and didn't see that error with the latest version of Sniper. The makefiles normally get the new version automatically. Can you try a 'make distclean' followed by a 'make' to get the latest version of Python?

Trevor

Hi Trevor,

I tried make distclean and then make on SNIPER-4.0.
I still have the same error, anyway distclean gives me this output

$ make distclean
[CLEAN ] logs
[CLEAN ] config
[CLEAN ] deps
[CLEAN ] standalone
[CLEAN ] pin

[CLEAN ] sift

make: *** //***********/sniper-4.0/doc/manual: No such file or directory.  Stop.
make: *** [manualclean] Error 2
sreda@scalelab:~/workspace/x86simulator/sniper/sniper-4.0$ make
mkdir -p python_kit/ia32
wget -O - --no-verbose "http://snipersim.org/packages/sniper-python27-ia32.tgz" | tar xz --strip-components 1 -C python_kit/ia32

my python is Python 2.7.3.



do you have any other suggestion?

Thanks,
Francesco

Hi Francesco,

Looks like the latest 32-bit version of our Python package wasn't
built properly, sorry about that. It should be fixed now, can you do
another make distclean + make?

Thanks,
Wim

Hi Wim,

I tried again. I got the same error.

Look forward to hearing from you!

Thanks,
Francesco

Fi Francesco,

Look at this link "/home/wheirman/src/exascience/graphite-master/python_kit/lib", I think the problem is in compiling python-kit. Seem that the library link to python-kit library is fixed to Wim's machine therefore running Sniper on user machine has problem. I worked around this issues by looking at python.pc in python-kit library but error is not solved.

I prefer to have pre-compiled python-kit then a update Makefile that support compiling python-kit rather than download post-compiled python-kin from website

Hi Tung,

I actually tried right now to remove the python_kit folder and execute make distclean & make again. Now it works!
By the way thank you for your suggestions, I'll keep them in mind!

Best,
Francesco
