2014-08-14Using nvcc present in CUDA_INSTALL_PATH instead of the one in PATHAndrew M. B. Boktor
Adding -DCUDART_VERSION to CXXFLAGS [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12253]
2014-08-14This changelist implements the following:Andrew M. B. Boktor
1. Adds support for using cuobjdump for both ptx and ptxplus execution. This has been tested with CUDA 4.0 . Ptxplus is no longer supported through decuda/decuda_to_ptxplus 2. Adds support for converting the SASS output by cuobjdump to ptxplus. This has been tested with CUDA 4.0 . The old path that extracts ptx from cubin files is still preserved 3. Adds a bank group model. (WARNING: memory config has changed, please adapt yours). To disable the bank groups model, set nbkgrp to 1 and tCCDL and tRTPL to 0 Diff the configuration files to learn about how to use those new options.

2014-08-14Fixed build fail when there is no openclAndrew M. B. Boktor
Now, you have to define both NVOPENCL_LIBDIR and NVOPENCL_INCDIR in the setupd_environment script to build with opencl. If any of them is not setup, gpgpu-sim will build will output a warning and built without opencl support. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 10873]

2014-08-14- Minor change to make things simpler, basically removing all instances ofAndrew M. B. Boktor
$CUDAHOME and replacing them with $CUDA_INSTALL_PATH. Removing all instances of $NVIDIA_CUDA_SDK_LOCATION with $NVIDIA_COMPUTE_SDK_LOCATION. - Some additions/changes to the README file to make it a little more intuitive. - Default values added to setup_environment to make things easier for the average user. - My first perforce submit :D [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 10401]

[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 10090]
2014-08-14Initial modifications to the opencl runtime API to allow the AMD sample ↵Tayler Hetherington
applications to run. Some of these modifications are temporary or incomplete and will be modified as necessary. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 9942]
2014-08-14Integration change. Bringing in the remote opencl changes from mem_divergenceTim Rogers
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 9764]
2011-07-07Integration change. Bringing in some changes from mem_divergence that allow ↵Tim Rogers
for multiple configs of the built simulator to exist at one time. Now you no longer have to clean build when changing from debug to release configs it also eliminates the possibility of having a fraken-file where some objects are in debug and some are in release. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 9743]
2010-12-28- parameter memory and active threads now part of kernel_info_t:Tor Aamodt
Parameters are finalized at kernel launch, which means the contents of parameter memory are initialized. Kernel arguement names have a fixed order, hence same address should be assigned on subsequent kernel launches of same kernel in other streams provided the data size param_t::size of arguments for each kernel launch is identical (an assertion has been added to check this is true). - passing regression [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 8303]
2010-12-28- Checkpointing new support for concurrent kernel execution (CUDA only, not ↵Tor Aamodt
OpenCL) This changelist adds full support for streams supported by a new class, stream_manager and enables concurrent execution of kernels from different streams. - fast_regression.sh fails for simpleMultiCopy, simpleStreams (other tests passing) ** Known issues ** - Kernel parameter passing is not done correctly for concurrent kernel execution (somehow concurrentKernels is not affected by this): the parameters are stored inside function_info, which is shared among parallel kernel launches so that the values passed into the launch are likely to get overwritten if multiple grids are launched in parallel streams. - Statistics are printed out whenever the simulation thread runs out of cuda commands (doesn't make sense to print out when a kernel ends during concurrent kernel execution). This will probably require further tweaking so as to be more compatible with data collection scripts. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 8302]
2010-10-241. adding top level configuration class and making shader and memory ↵Tor Aamodt
configuration components of this class. 2. clock memory pipeline no. subwarp times for each shader clock and increase rob-size for texture cache (trying to improve correlation, currently at 0.9218) 3. start to modify shader stats to add back features for visualizer (warp divergence distribution kind of working again) passing cuda 3.1 regression and ptxplus correlation tests [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7909]
2010-10-18Re-designed cache model:Tor Aamodt
- read only cache model with integrated mshrs (no L1D, yet); new cache interface should be easily extendable to support texture cache with latency fifo and separate tag/data arrays, though this is not yet added (currently tags and data arrays are not decoupled for texture) - new partition model using the above removes all old MSHRs, L1D etc... passing CUDA 3.1 regression [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7875]
2010-10-161. enable OpenCL to PTX compilation on remote host without NFSTor Aamodt
2. hopefully one-size-fits-all setup_environment script [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7866]

2010-10-09refactoring: moving texture reference mappings into gpgpu_t Tor Aamodt
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7835]
2010-10-081. refactoring cuda api code for loading PTX (removing external PTX loading ↵Tor Aamodt
entirely) 2. some bug fixes for warp_inst_t 3. creating a new class, gpgpu_t, which contains the functional "memory" state visible to all threads running on a GPU (doing this as part of my continuing effort to hunt down and eradicate every global variable that is not the top level "the gpu") 4. other misc. changes Almost passing CUDA 3.1 regression? oclHistogram keeps failing under torque, but does not fail when run on the command line from the same directory. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7827]
2010-10-01integrating recent changes from fermi-test into fermiTor Aamodt
(i'll use "fermi" for more disruptive changes to the pipeline model such as updating the MSHRs and getting rid of the warp tracker, ripping out DWF, etc...) [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7805]
2010-08-23- oclMatrixMul passing (added support for dynamically allocating shared ↵Tor Aamodt
memory on kernel launch for OpenCL) - added some debugging printfs to oclMatrixMul [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7255]
2010-08-23- add '-keep' option to keep intermediate files (used for OpenCL only right now)Tor Aamodt
- remove redundant initialization code of options (which confuses new users) - make bool option variables bool type - remove some more extern decls [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7247]
2010-08-12- allow multiple clCreateBuffer wth same host_ptr (undefined behavior in ↵Tor Aamodt
OpenCL spec, but required for oclTranspose). - undo earlier fix that wasn't a fix [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7194]

(differences) [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7170]
2010-08-08oclSortingNetworks passing: update workgroup size calculation (now ignores Tor Aamodt
shared memory usage since I believe the assumption is at least a single CTA can run for this calculation) [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7169]
2010-08-08** fully decouple kernel compilation from kernel launch for openclTor Aamodt
changes required to do this (this enables oclReduction SDK 3.1 to pass and is a prerequisite to Fermi style concurrent kernel launching) - separate kernel launch for cuda and opencl (and init_grid functions) - add pgm_info structure for holding kernel function_info pointer in _cl_program object after ptx compilation ** added support for clEnqueueNDRangeKernel with local_work_size==NULL which is part of OpenCL spec and used in oclSortingNetworks (however, this is a braindead implementation that only handles the case where global_work_size[0] is smaller than the max number of threads per shader; moreover oclSortingNetworks is still not working but for what looks like another reason) ** refactoring / cleanup - g_global_symbol_table made static to ptx_parser.cc - remove g_kernel_name_to_symtab_lookup (not really being used) - moving various function prototypes into headers (e.g., if foo() defined in bar.cc, then place prototype in bar.h) - adding icnt_reg_options() [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7168]
