2014-08-14Lengthened the DRAM return queue size to have enough credits in order to ↵Wilson Fung
keep the DRAM utilized. Also extended the state printing function to print out mem_fetch entries inside the DRAM delay queue. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 16639]
2014-08-14Fix for bug 63. bk[i]->n_idle should be bk[j]->n_idle instead.Wilson Fung
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 16635]
2014-08-14Redesigned the memory partition unit to support multiple L2 cache banks per ↵Wilson Fung
partition. Each L2 cache banks has its own connection to the interconnection network to allow L2 bandwidth to scale without increase the number of memory parttiion units. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 16613]
2014-08-14Adding option to force global memory accesses to skip L1 data cache while ↵Wilson Fung
still caching data from local memory space. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 16601]
2014-08-14Integrating changes from my personal branch.Tim Rogers
Main contribution is a static warp limiting scheduler. There is also some minor cleanup to the heirarchy of the cache code and removal some excessively long lines Review ID: 36001 lgtm: 1 [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 16580]
2014-08-14Review 62001: Fixing bug where labels "WarpIssueSlotBreakdown" and ↵Tayler Hetherington

2014-08-14Adding new option '-liveness_message_freq', which throttles the frequency of ↵Wilson Fung
simulation liveness printout (default to 1 per second in wall clock time). [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 16482]
2014-08-14Fixing ":" to "=" in shader_print_cache_stats. This will not affect the ↵Tayler Hetherington
regressions butwill cause the correlation to fail due to a change in the output - need to update gold files on failure. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 16477]
2014-08-14Review: 47001. Fixing bug in CL16463. When streams are actually used, ↵Tayler Hetherington
kernels can complete while other kernels are still running. The fix in CL16463 caused the GPU to re-initialize when a kernel completes, which may occur while another kernel is still running. Added a check to test if the GPU is also inactive when a kernel completes in order to re-initialize. simpleStreams CUDA SDK now passes with CUDA 3.1. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 16469]
2014-08-14Review: 46001. Fixing a source of non-determinism in GPGPU-Sim (Bug 174). ↵Tayler Hetherington
Not sure if this is the only issue, but this was definitely a source of non-determinism (checked with many of the <rodinia>-FT benchmarks). In gpgpu_sim_thread_concurrent() (gpgpusim_entrypoint.cc), the inner do{...}while(active); only breaks when the gpu is not active. As a result, the gpu is only initialized when the gpu becomes momentarily inactive. If one kernel completes while another kernel is currently pending in the stream's queue, the next kernel will start running immediately causing the GPU to not be reinitialized (which includes resetting per-kernel stats). The fix simply recognizes that a kernel has completed and breaks from the loop prior to starting the next operation. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 16463]
2014-08-14Fixing pending_hit bug (Access is supposed to return MISS, but stats should ↵Tayler Hetherington

2014-08-14Review: 33001. Updating/cleaning up the cache statistics. Moving the ↵Tayler Hetherington
statistics from the tag array to the cache access functions. Added cache_stats class to record all memory accesses and access outcomes to each cache. Removed L2CacheAccessBreakdown_t. Cleaned up power_stats to reflect changes in the cache stats. Updated the cache stats printing. This will cause the performance gold files to change as the output format has been changed.

L1 Cache and Shared Memory configurations across kernels. The support enable the user to specify two more configurations (Preferred L1) or (Preferred Shared Memory) besides the default config. If the cudaFuncSetCacheConfig API is used to set the cache configuration of a specific kernel to either of these configuration (cudaFuncCachePreferShared, cudaFuncCachePreferL1), the simulator will change the cache configuration at kernel launch accordingly, if there is no alternative configurations provided to the simulator it will use the default configurations with a warning message display [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 15816]
