2014-08-14Remove memory leak in cudaSetupArgument()Wilson Fung
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 14564]
2014-08-14Adding support for cudaReadModeNormalizedFloat (a texture read mode). See ↵Wilson Fung
bug 18 (external) for detail. The blocked SDK benchmarks are still not working due to mismatch of texture element layout in memory between real GPU and GPGPU-Sim. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13933]
2014-08-14Fix compilation error with CUDA 2.3.Wilson Fung
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13868]
2014-08-14Allowing cuobjdump on the executable to return error when experimental ↵Wilson Fung
library support is enabled. This fixes the crash for applications that exclusively use kernels from CUDA libraries and do not contain kernels in their own executables. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13867]
2014-08-14Fixing the case where cuobjdump is not used for on demand loading of binariesAndrew M. B. Boktor

2014-08-14Fixing build fail on JenkinsAndrew M. B. Boktor
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13794]
2014-08-14On demand loading of fatbinsAndrew M. B. Boktor
Experimental library support (diff abstract_hardware_model.cc) (currently broken because of undocumented cudaGetExportTable function in the cuda rt api) [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13793]
2014-08-14 Integration from TM-311 branch.Wilson Fung
- Updated PTX parser to support CUDA 4.1 and 4.2. - Revised fatbin workaround to a more robust version (with comments explaining it). - Added print_simulation_time() in gpgpu_sim_thread_concurrent(). [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13789]
2014-08-14Extended andrew's fatbin hack to support CUDA 4.1 and 4.2 as well.Wilson Fung

[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13730]
2014-08-14Adding a less brittle support for associating the fatbins to sections in the ↵Andrew M. B. Boktor
output of cuobjdump This is how to get to the filename given a fatCubin void* void * s1 = *((void**)(fatCubin+8)); void * s2 = (s1+72); char * filename = (char *)s2; [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13728]

2014-08-14Back out changelist 13683Andrew M. B. Boktor
There is a problem with the linkage on my machine. Before this changelist the code didn't build on my machine. After it it builds but fails to run due to missing dynamic linkage. And obviously it breaks the jenkins build. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13684]

Fixing failed compilation due to double definition of parsing functions [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13683]
2014-08-14Clean up the unordered_map fallback support.Wilson Fung
- Now there is only one macro for all use of unordered_map in the code. - Moving all instances of gcc/cuda version detection into a single file. - Adding a warning when the fallback is triggered. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13542]
2014-08-14Now makedepend doesn't have to interfere with our commits anymore.Andrew M. B. Boktor
makedepend generates the dependencies in Makefile.makedepend that is generated dynamically and cleaned with "make clean" Next step is to use gcc's "-M" option and get rid of makedepend altogether. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13292]

2014-08-14Moving things where they belongAndrew M. B. Boktor
cubojdump.l/.y are used to parse the output of cuobjdump, and thus should be part of libcuda not cuobjdump_to_ptxplus Included are also modifications to Makefiles [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12255]

Stopping if someone tries to use PTXPlus without cuobjdump [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12138]
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.

2014-08-14Undoing the rest of files mistakly changed in CL10695, this change completes ↵Ayub Gubran
the work of CL10697 which undone the changes to one file (stream_manager.cc). Here I undo the changes for 4 make files and more importantly the setup_enviroment file where I uncommented the include path of openCL as the case before CL10695, and I kept Tim changes to the CUDA path done later in CL10723 which he made originally to undo the work I did but didn't uncommet the openCL path which I do here.

$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]

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.

2011-04-09initial edits to compile with CUDA 2.3 (passes regression with CUDA 3.1)Tor Aamodt
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 8762]
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]

correctly (off-by-one error) 2. adding code to dump_pipeline to display reason for memory stage stalling 3. removing dead code resulting from prior changes correlation vs. GT200 is 0.95 (need to add back modeling of memory writebacks, shared memory latency) [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7831]

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.
