2014-08-14fixing a bug that cause the thread_fence benchmark fails (excluding an ↵Ahmed El-Shafiey
opcode that does not have operands "mem_bar" from checking its operands types) [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 14738]
2014-08-14Merging Power model into FermiTayler Hetherington
//depot/gpgpu_sim_research/fermi_power/distribution/... to //depot/gpgpu_sim_research/fermi/distribution/... [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 14723]
2014-08-14Changing the QuadroFX5800 config to use compute capability 1.3 (no idea why ↵Wilson Fung
it was not...). Adding sign-extension mode for cvt.s16.s32 that writes to a .u32 register. Adding stub parsing for .maxnctapersm directive. Removing benchmarks with known-issues from regression list for now. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 14572]
2014-08-14Fixed a bug introduced in CL14565 for PTXPlus.Wilson Fung
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 14566]
2014-08-14Extended PTX parser to recognize the .ptr .shared directive and allocate ↵Wilson Fung
shared memory buffer to those pointers. This is required to support OpenCL local memorywith the newer NVIDIA driver. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 14565]
2014-08-14OpenCL newer diver fixHadi Jooybar
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 14554]
2014-08-14Fixed the timing model for LDU instruction, before it was not recognized as ↵Wilson Fung
a memory instruction in the timing model. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 14538]
2014-08-14Added functional execution support for shared memory atomic operations.Inderpreet Singh
Integrated in CL14335 and CL14336 [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 14366]
2014-08-14Several changes to ptxplus towards getting the sphyraena benchmark to work. ↵Jimmy Kwa
Add .false modifier to cuobjdump_to_ptxplus. It isn't supported in gpgpusim yet since we don't know what it does. Fixed most of the issues with global (const14) variable not being declared properly. Added "BRX" instruction to cuobjdump_to_ptxplus and some support for it in gpgpusim. There are other issues with it that still need to be worked out. Added support for translating IADD.CARRY sass instruction into ptxplus addp instructions. Fixed a bug with generating ".half" modifiers on instructions so the ptxplus instruction addresses should match sass addresses now. Separated ssy instructions from nop. However, they are still simulated as nop in gpgpusim. Sometime cuobjdump generate a blank link that takes up an address slot. This was changed to a nop. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 14001]
2014-08-14Fixing regression failure: vote.all was broken by vote.ballet implementation.Wilson Fung
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13996]
2014-08-14Added implementation of vote.ballot (passing directed test). Added popc ↵Wilson Fung
(not tested). Reducing number of iterations for radixSortThrust for regression. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13993]
2014-08-14Fixing texture fetching for 1D texture with non-normalized coordinates: ↵Wilson Fung
Adding support for the floating point input coordinate, and handling of out-of-bound coordinates. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13959]
2014-08-14Fixing multi-element texel access. Now texture with RGBA components are ↵Wilson Fung
read properly. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13949]
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]
2014-08-14Extending ptx.y to ignore the .minnctapersm directive (at least it will not ↵Wilson Fung
crash the simulator for now). [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13841]
2014-08-14Adding single element vector operands to support tex.1d instructions in CUDA ↵Wilson Fung
4.1 and later. KMN-FT should pass with this changelist. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13833]
2014-08-14Fixing the updated PTX parser for texture instructions. Created a new state ↵Wilson Fung
for function declaration, which is terminated with LEFT_BRACE "{" to return to INITIAL state. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13790]
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]
2014-08-14Fixing bugs 169, 170, 171Ahmed El-Shafiey
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13761]
2014-08-14Integration from tm-311 branch. Adding support for atomic operation with ↵Wilson Fung
generic memory space. Also adding a define to allow support for OpenCL 1.0 commands that are deprecated in OpenCL 1.1. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13722]
2014-08-14Fixing compile error on my machineAndrew M. B. Boktor
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13703]
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]
2014-08-14Removing compiler warningsAndrew M. B. Boktor
Fixing failed compilation due to double definition of parsing functions [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13683]
2014-08-14Putting GPGPU-sim into nvcc version specific build and lib folders.Tim Rogers
Also changing the cuobjdump_to_ptxplus build to into the build directory instead of inline with the src [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13567]
2014-08-14- can compile on MacOSX (tested on Lion)... no regression testing done on MacTor Aamodt
- ptxplus ... edits to eliminate some warnings with older gcc about printfs without string literal - eliminate warning about map (just too annoying while testing on Mac) [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13560]
2014-08-14Adding missing math functions for mac osx compatiblity.Wilson Fung
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13558]
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]

2014-08-14- print out instructions at branch divergence/reconvergence points (more ↵Tor Aamodt
informative) [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13399]
2014-08-14Fix for bug 9: Now querying the state of the pdom stack in call_imp and ↵Ayub Gubran
callp_imp using a core_t function, thus moving the querying function into the abstract model of the core instead of shader_core_ctx which represents the performance mode. This code simplify the querying and also avoid the unnecessary calling hierarchy that was used. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13375]
2014-08-14Fix for bug #154-internal and #8-externalAndrew M. B. Boktor
Adding support for double destination to mad instruction Fixing broken madp instruction Adding a patch to cuobjdump_to_ptxplus to work around the C3 problem (Documented in bug #154 internal). [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13349]
2014-08-14Adding the madp instruction, which does multiply add with carry-in. Still ↵Wilson Fung
need to modify carry and overflow flags. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13317]
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]
2014-08-14Fixing one of the problems discovered for bug 154 (internal).Wilson Fung
- Output of 16-bit integer multiplication (IMUL.U16) writes to the entire 32-bit register if a full register (i.e. not half register such as R1L) is specified as the destination. Before, it was only storing the lower 16-bit of the product into the full register. - Modified function header to declare at least 4 predicates in cuobjdump_to_ptxplus. This will mask out the problem with the predicate registers used before initialized. - Modified register value print out: now unsigned integers display their decimal values as well. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13246]
2014-08-14- Update README file to be slightly more user friendly (i.e., try not to ↵Tor Aamodt
imply user should bugger off and stop asking developer for help) - Remove ridiculously long and cryptic comment from setup_environment. Most people will use CUDA_INSTALL_PATH. - Remove decuda targets from Makefile - Add check to Makefile to insist that setup_environment was run first - Add version file (eliminate redundancy) and remove version strings from src/cuda-sim/cuda-sim.cc [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12874]

[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12518]
2014-08-14Adding configurable instruction latencies and initiation intervalsAndrew M. B. Boktor
The observed latencies are reduced by 5 to account for other stages in the SM pipeline Eventually this should be calibrated against the microbenchmarks [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12310]
2014-08-14Supporting the option for removing temporary filesAndrew M. B. Boktor
. the option -gpgpu_ptx_save_converted_ptxplus allows keeping the ptxplus file . the option -gpgpu_keep allows keeping intermediate files used to communicate with other programs (e.g. cuobjdump) [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12304]
2014-08-141. Fixing ptx with sm_20Andrew M. B. Boktor
2. Fixing the choice of files (since new we can choose) 3. Not allowing sm_20 with PTXPlus, forcing max capability it to 19 and printing a warning [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12279]
