update README and CHANGES to hopefully anticipate most basic questions we'll see [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 9880]

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]
2010-10-09refactoring: 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]
2010-10-05broken change list: builds, but does not run, yetTor Aamodt
refactoring: create warp_inst_t that provides notion of a group of scalar instructions traveling down the pipeline. delete DWF delete MIMD delete warp_tracker delete old writeback stage, replace it with a stub that just writes back everything delete old pipeline model current status: MSHR's need to change to deal with the new structure [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7814]
2010-10-03moving some CUDA API centric code to cuda_runtime_api.ccTor Aamodt
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7811]
2010-10-031. enable L2 cache as a texture cache (also some bug fixes for L2 as regular ↵Tor Aamodt
cache) 2. update gpgpusim.config for Quadro to use L1 cache geometry from Henry's ISPASS paper 3. minor edit to CUDA api : add notion of fat_cubin_handle (currently not used for anything) 4. minor edits to deadlock detection message (more accurate reporting of source of deadlock) 5. other minor edits [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7809]
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]
2010-08-30integrating 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]
2010-08-29- integrate changes from fermi-test (CL's under that path in range 7261-7418).Tor Aamodt
(add scoreboard logic from ptxplus branch and modified operand collector with parallel ALU/SFU pipelines) passing regressions [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7419]
2010-08-10refactor: mostly finished getting rid of extern declTor Aamodt

[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7176]
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]
