Allowing modern GPU configrations to properly run PTXPLUS.
There are several problems with this:
1) To get proper occupancy, based on register file usage, you must querry ptxas with
the sm version that corresponds to the register usage in the config file. To enable this,
a new config option has been added that determines what sm version you pass to ptxas to compute reg-usage.
This configuration option is always required in the gpgpusim.config file
2) If you are running PTXPLUS with a modern card (i.e. volta/pascal), you need ptxas from CUDA 9.1.
However since PTXPLUS only supports sm_13 - you need a version of CUDA where cudaobjectdump
supports sm_1x. This ended at CUDA 5 - and PTXPLUS requires CUDA 4.2. Therefore, to run PTXPLUS
on a modern card, you need CUDA 4.2 + modern CUDA installed. To fascilitate this, a new envronment
varaible is added and the setup envrionment script prints an appropraite warning if you are using a newer CUDA.
We have tried to make this as fail-proof as possible - and die appropraitely when something is wrong.
