2018-06-30Cleaning up the setup env message a bit and having the simulator properly ↵tgrogers

2018-06-30changing the flow s.t. you cannot compile the simulator with a different ↵tgrogers
version of CUDA from the app.
2018-06-29Fixing the PTXPLUS + new CUDA execution case.tgrogers
2018-06-29Allowing modern GPU configrations to properly run PTXPLUS.tgrogers
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.

2017-07-06Adding the correct dependency for the detailed_version file. In order to ↵tgrogers
updatet the built number output when we run gpgpu-sim we need to recompile cuda-sim everytime the detailed_version has changed
2017-05-17Changing the version detection to be much more detailed. Now the git commit ↵tgrogers
# and branch will be embedded in the built executable and print out when gpgpu-sim runs
2017-05-09Fix next block addr to link predicate ret block to consecutive blockMengchi Zhang
The block containing predicate ret instruction should add the consecutive block to its successor_ids set. next_addr should be assigned with current instruction address add instruction size instead of 1. Signed-off-by: Mengchi Zhang <[email protected]>

2016-07-04Restored madp instruction.speverel
2016-07-04Reverted part of the previous commit so that our new changes related to DNNs ↵sspenst
can be done in a different branch
2016-06-16Added the ability to inject arbitrary PTX instructions. ↵speverel
This will be used to add custom instructions in the future; the imaginary instructions 'spr' and 'ama' have been added as samples.
2016-06-13If ptxas notices any duplicate errors, they now automatically get resolved ↵sspenst
and the program continues with the duplicate function/variable declarations removed.
2016-06-07The ptx parser now recognizes the NC option for ld.global, however this ↵sspenst
option is not actually implemented
2016-06-06Added support for BFE (Bit field extract) instruction.speverel
2016-06-03Added support for %laneid SFR. Also added a notice clarifying that power ↵speverel
modeling for GTX750Ti is currently completely untested and should not be considered supported.
