2014-08-14Replaced the legacy L2 cache access stats with more meaningful breakdown ↵Wilson Fung

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]
2014-08-14Supporting 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]
2014-08-14This 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.

2014-08-14Fix for bug 144. Now warp parts option is used in coalescing logic (before ↵Wilson Fung
it was always hardcoded to 2). [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 11742]
2014-08-14Fix for bug 129. Created a directed test with a pre-known instruction count, ↵Wilson Fung
and observed the over-count for vector memory instruction. The fix eliminates the over-count. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 11481]

2011-05-25Fix bug #100: local memory address translation returns multiple addressesInderpreet Singh
Fix bug #101: Coalescing allows multiple accesses per thread for local memory access This will break atomics which assume at most one thread per mem_fetch. It did not break scoreboard as that logic tracks mem_fetches at warp level, not thread level. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 9303]
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]
