Encountered Problems

• GPGPU-Sim is beta Here be dragons ;)

– Needs Python2.6

• Ubuntu 8.10 relies on Python2.5

• Ubuntu 9.10 Python 2.6– But has gcc/g++ 4.4need to replace by gcc/g++ 4.3 for CUDA

– Broken links in installscript of AerialVision

• Unfulfilled dependencies of built packages– RTFM! Pay attention to error-msg’s during install

– Alternatively, install needed packages through e.g. Synaptic

Conclusion

• Had some problems getting it to work• Lots of detail on hardware since it’s meant as a

tool for researching different architectures, but some exposure to this cannot hurt

• AerialVision seems very promising for gaining insight in your code =)

• Config-files needed for your card

• More details in the wiki later, and curious for your experiences with the tool.
