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.

imply user should bugger off and stop asking developer for help) - Remove ridiculously long and cryptic comment from setup_environment.

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]
2010-12-15Added next instruction type to ptxplus, ".ff64". It's the same as ".f64" ↵Jimmy Kwa
except it reads and stores from two adjacent registers instead of a single 64 bit register. ".ff64" instructions are now printed in decuda_to_ptxplus. Support in the simulator for ".ff64" has been added but it is untested. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 8278]

2010-10-240.9756 correlation. Set L1T line size to 128 bytes... problem wasTor Aamodt
stalling to send four requests per warp into L1T tag lookup. If L1T is really 32B blocks (as per Henry's paper), this suggests banking of L1T needs to be modeled. Other changes: 1. bug fix in memory access generation for texture/const cache access 2. adding back memory latency measurement for visualizer [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7913]

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]

(a) update scoreboard to keep count of outstanding memory requests and use operand collector for writebacks into register file (b) add back shared memory pipeline delay (c) remove use of MSHR's for non-cached global/local accesses (d) replace texture cache with a split tag/data array pipe (e) re-implement memory_partition stuff so it makes more sense [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7844]
2010-10-09refactor: renaming some texture reference variables after moving to gpgpu_tTor Aamodt

2010-10-09refactoring: moving texture reference mappings into gpgpu_t Tor Aamodt
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7835]
2010-10-09Refactoring:Tor Aamodt
1. Moving mem_access_t to abstract_hardware_model and making set (queue) of accesses part of warp_inst_t. I.e., treat set of accesses as an ISA concept rather than a hardware organization concept. This is only partly "done"... logic for computing accesses is still part of shader_core_ctx in this CL. Given number of warp_inst_t accessors for accessq, now seems like we might even want to move some memory stage code into warp_inst_t class. How those accesses make it to memory system is the hardware concept. 2. Making warp_inst_t an explicit arguement of subroutines used in memory stage... The eventual goal here is (likely) to refactor memory into a hardware block... i.e., have function units be a class that contains some set of pipeline stages internally and some set of input/output "ports". 3. Moving accessor functions is_load, is_store; is_const, is_local into class declaration (where they belong). 4. Removing code for selecting pipeline uarch (might add it back later, but first want a clean GT200 organization). In particular, removing option to have an operand collector -- now you MUST have the operand collector. 5. Removing more deadcode from prior changes (fixed delay queue related) Scripts/configs: 6. Correlation script not printing out exit condition when hardware launch fails 7. Update config files to have proper compute model selected [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7834]
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.
