2011-07-07A couple changes for the mem_divergence branchTim Rogers
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 9747]
2011-07-07Integration change. Bringing in some changes from mem_divergence that allow ↵Tim Rogers
for multiple configs of the built simulator to exist at one time. Now you no longer have to clean build when changing from debug to release configs it also eliminates the possibility of having a fraken-file where some objects are in debug and some are in release.

2011-05-25Bug fix for local memory address translation that was made in tm-test branch ↵Inderpreet Singh
but missed in the last changelist for this (fermi) branch. (CL9267) [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 9307]
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]

2010-12-28the assertionTor Aamodt
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 8304]
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]
2010-12-21added support for negative .f64 operands in decuda_to_ptxplusJimmy Kwa

2010-12-20fix from CL 8285Tor Aamodt
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 8287]
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]
2010-12-09Copied cuobjdump_to_ptxplus into fermi branch. Minor modifications were made ↵Jimmy Kwa
to decuda_to_ptxplus to support this. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 8229]

download/patch Decuda. Modified config file for ptxplus regression so it runs the converted ptxplus. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 8002]

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. updates to .gdbinit fileTor Aamodt

2010-10-241. fix load imbalance issue (CTA's were filling up first core in a cluster ↵Tor Aamodt
before moving to next) this improves correlation to 0.9471 2. update config to use sm_12 if available (goal: seems like BlackScholes has different ipc on hardware from before, this didn't help though) 3. update comparison scripts since no ld_const stuff was removed [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7911]

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]
2010-10-22enables global loads/stores for ptxplusTor Aamodt
passing CUDA 3.1 and ptxplus correlation correlation back to around 0.89 on ptxplus vs quadro fx5800 [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7898]
2010-10-211. rewriting memory access generation code (from scratch), why not...Tor Aamodt
passing CUDA 3.1 and ptxplus correlation, but correlation still bad (0.62)... after debugging 1 to get it working with ptxplus, problem is very clear: shared and constant cache accesses not occuring for operations that combine these with ALU operations. TODO: have a "read-operands" stage, which somehow combines operand collector register reading with shared and const memory accesses... [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7895]
