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

2014-08-14Putting GPGPU-sim into nvcc version specific build and lib folders.Tim Rogers
Also changing the cuobjdump_to_ptxplus build to into the build directory instead of inline with the src [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13567]
2014-08-14- can compile on MacOSX (tested on Lion)... no regression testing done on MacTor Aamodt
- ptxplus ... edits to eliminate some warnings with older gcc about printfs without string literal - eliminate warning about map (just too annoying while testing on Mac) [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13560]
2014-08-14Adding missing math functions for mac osx compatiblity.Wilson Fung
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13558]
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]

2014-08-14Ptxplus fix for recrusive call handling in SIMT stack (CL13410).Inderpreet Singh
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13435]
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]
2014-08-14Copied in Arun's SIMT stack fix for recursive calls (CL8574)Inderpreet Singh
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13410]
2014-08-14- print out instructions at branch divergence/reconvergence points (more ↵Tor Aamodt
informative) [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13399]
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]
2014-08-14Fix for bug #154-internal and #8-externalAndrew M. B. Boktor
Adding support for double destination to mad instruction Fixing broken madp instruction Adding a patch to cuobjdump_to_ptxplus to work around the C3 problem (Documented in bug #154 internal). [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13349]
2014-08-14Adding the madp instruction, which does multiply add with carry-in. Still ↵Wilson Fung
need to modify carry and overflow flags. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13317]
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]
2014-08-14Fixing one of the problems discovered for bug 154 (internal).Wilson Fung
- Output of 16-bit integer multiplication (IMUL.U16) writes to the entire 32-bit register if a full register (i.e. not half register such as R1L) is specified as the destination. Before, it was only storing the lower 16-bit of the product into the full register. - Modified function header to declare at least 4 predicates in cuobjdump_to_ptxplus. This will mask out the problem with the predicate registers used before initialized. - Modified register value print out: now unsigned integers display their decimal values as well. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13246]
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]
2014-08-14- Update README file to be slightly more user friendly (i.e., try not to ↵Tor Aamodt
imply user should bugger off and stop asking developer for help) - Remove ridiculously long and cryptic comment from setup_environment. Most people will use CUDA_INSTALL_PATH. - Remove decuda targets from Makefile - Add check to Makefile to insist that setup_environment was run first - Add version file (eliminate redundancy) and remove version strings from src/cuda-sim/cuda-sim.cc [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12874]
2014-08-14- adding clearer documentation to setup_environmentTor Aamodt
- removing an assert that gets triggered when using CUDA 4.2 [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12865]

[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]
2014-08-14When 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. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12362]

2014-08-14Fixing a potential problem.Andrew M. B. Boktor
Right now this doesn't cause any trouble becaue increment_thread_id guarantees that this particular part of the condition is never false (in correct operation) Normal kernel configuration have the z dimention smaller than the x dimention which causes it to be always true, but with a weird configuration, this is a potential place for failure. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12357]

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]
