2014-08-14Updating comment in l1/l2 access functionsTayler Hetherington
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 14199]
2014-08-14gpu-cache revision #3. Now adding in function pointers for l1/l2 cache ↵Tayler Hetherington
access functions. Removes the multiple long flaky branches in the access functions (caused by multiple config options) and replaces them with a single function that is set in the constructor to reflect the current configuration. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 14198]
2014-08-14Revision #2 of modifying the cache hierarchy.Tayler Hetherington
Separated the L1 and L2 cache access() implementations. Removed PRIVATE/SHARED cache scope configurations. Added WRITE_EVICT cache write policy. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 14109]
2014-08-14Adding/updating comments for classes/functions on the recent changes ↵Tayler Hetherington
(Doxygen notation). Removing some error checking /debugging code [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 14091]

gpu-cache.h to gpu-cache.cc for mshr_table, baseline/read_only/data/texture_caches [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 14090]
2014-08-14Modified the cache hierarchy, reorganized code to eliminate code ↵Tayler Hetherington
replication, implemented write allocate / write back policies in L2 cache, added configurable parameters in gpgpusim.config ("W" = Write Allocate, "N" = No write allocate -> "P" = Private, "S" = shared), modified the cache configuration lines to always be separated by ":" instead of ":" and ",", and modified L1 and L2 data cache to be "Write Back" caches instead of "Read Only". Still need to implement Ahmed's sectored cache implementation. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 14081]

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]
2014-08-14Some Errors reported by valgrindTim Rogers
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13595]
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]
2014-08-14Fixing an error reported by valgrind.Tim Rogers
Is really harmless since you can call delete on primatives allocated with new[] without consequence (all delete [] does is ensure that the destructors will be called) Still, it is always good practice to de-allocate anything allocated with new[] with delete[] - just in case the type allocated changes and the person that changes it forgets to update the de-allocation. Really, this little array should be on the stack... [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13414]
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]
2014-08-14Now 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]
2014-08-14Adding a two level scheduler as described in the ISCA 2012 tutorialAndrew M. B. Boktor
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13261]
2014-08-14Fixed DRAM performance statistics to display information for more than 4 banks.Wilson Fung
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13139]
2014-08-14Fixed GDDR5 parameters in Fermi config:Wilson Fung
- Increased burst length to 8 and changed address mapping to reflect 16 banks as suggested by Jungrae. - Decreased the DRAM clock to 924MHz from 1848MHz. - Corrected CAS Latency and Write Latency in the timing constraints. - Added a new option 'dram_data_command_freq_ratio' to configure the frequency ratio between the DRAM data bus and command bus. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13138]
2014-08-14Fix for bug 168 (internal). The overall average memory latency should now ↵Wilson Fung
be reporting the actual overall, instead of the average of just the final sampling window for AerialVision. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13045]
2014-08-14Fixing bug 161 and 164. WP now runs without deadlocking due to I-cache miss ↵Wilson Fung

[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12383]
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]
2014-08-14Removing some bottlenecks that limit that peak-IPCAndrew M. B. Boktor
- FUs depended on the result bus to know if they are going to be used on a certain cycle, this is not the case anymore, occupied bitvectors are added - A configurable number of result buses is added (the number of buses is equal to the EX_WB pipe width) - Modified the Fermi config file to add two ports to the operand collector IPC with a theoretical limit of number_of_SMs*64 is achievable using this configuration [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12349]
2014-08-14Integrated in CL12342 from coherence branch; fix for bug #160Inderpreet Singh
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12343]
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]
2014-08-14Using only move_out_to to move pipeline registersAndrew M. B. Boktor

2014-08-14Removing a wrong commentAndrew M. B. Boktor
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12203]
2014-08-14This changelist adds the following:Andrew M. B. Boktor
1. A configurable number of functional units within each SM 2. A configurable pipeline widths (i.e. Issue width, writeback width ...). Merging //depot/gpgpu_sim_research/fermi_replay/distribution/src/... to //depot/gpgpu_sim_research/fermi/distribution/src/... [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12091]
2014-08-14Changing the configs to be backward compatible by disabling bank groups by ↵Andrew M. B. Boktor
default if its configurations are not present [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12033]
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. Merging //depot/gpgpu_sim_research/fermi-test/distribution/... to //depot/gpgpu_sim_research/fermi/distribution/... [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12023]
2014-08-14Integration change. Fixing bug for #149: A pathological case that caused LD ↵Wilson Fung
instructions to be over counted when the LD instruction is stalled for a long time after sending part of its memory requests. Those memory requests manage to return before the LD is done sending all of its requests. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 11888]

[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 11877]
2014-08-14Fixing bug 145. Now partition_address() works for non-power-of-two number ↵Wilson Fung
of memory partition as well (before it just leaves the memory address unchanged!). [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 11755]
