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 opencl statsAndrew M. B. Boktor
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12491]
2014-08-14A much easier way to attempt to fix the problem targeted by CL12362 is to ↵Andrew M. B. Boktor
just print the stats whenever a kernel is done. This requires decoupling updating the stats from printing them and modifying the printing code to accomodate this change. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12366]
2014-08-14When a kernel is done, it doesn't mean it finished executing. Instructions ↵Andrew M. B. Boktor
could have a few cycles left (e.g. memory). To prevent the problem with the race condition, no stream operations are allowed to launch until the kernel that has finished finished executing. The loop will exit, the kernel prints its stats, then in the next iteration the next operation is allowed to launch.

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]
2014-08-14This 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.

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]
2010-10-121. adding simt_core_cluster, which models a TPC or (for fermi) GPC...Tor Aamodt
this gives us a place to stick caches shared among shader cores but on the shader side of the interconnect... maybe move the clock boundary code here? after integrating booksim 2 code? 2. added a pending write table to ldst_unit rather than scoreboard ... rationale is that ld/st unit needs to process register writes once it is done it can notify scoreboard once. 3. re-enabled shared memory delay (use pipeline within ldst_unit) 4. re-enabling operand collector writeback for all instruction types 5. disable MSHRs in this change list passing CUDA 3.1 regression next? texture cache, then redo mshrs?

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.

2010-08-30integrating CL 7421-7434 from fermi-test Tor Aamodt
this integrates the ptxplus functional model changes, but has only been verified with CUDA 3.1 PTX regressions (which pass) still need to verify ptxplus itself is working in this branch [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7435]

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]
