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]
2014-08-14Updated the aerialvision log parser to detect for metric sample that ↵Wilson Fung
contains no data. Instead of crashing, it prints out an warning and proceeds. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 16569]
2014-08-14Adding the ability to querry the WARPSZ flag from the ptx script.Tim Rogers
Also changed some initialization code when cores are created in both the funcational and perfromance simulator review:3001 lgtm:5 [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 16506]
2014-08-14 Changing the make flow so all the generated files, both object and code ↵Tim Rogers
generated go in a directory independent of the source directory [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 16503]

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]

2014-08-14Review: 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]
2014-08-14Review: 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. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 16452]

2014-08-14Fixing 2 bugs & small code clean up:Tayler Hetherington
1: 'Constant dynamic' power not included in average/min/max power values. 2: Average/min/max per-kernel powers not being reset at kernel boundaries, causing incorrect per-kernel values. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 16405]

2014-08-14 - Adding support for cudaFuncSetCacheConfig API, that allows changing theAhmed El-Shafiey
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]
2014-08-14Fix for bug 53 and 54. Now clGetDeviceInfo() is returning CL_DEVICE_TYPE ↵Wilson Fung
property in the proper size. Also added code to determine the workgroup size automatically. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 15798]
2014-08-14Fix for bug 51 and 55: Declaration of clCreateContextFromType() is updated ↵Wilson Fung
to match OpenCL 1.1 and later. The API call now accepts device types besides CL_DEVICE_TYPE_GPU. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 15796]
2014-08-14Replaced the legacy L2 cache access stats with more meaningful breakdown ↵Wilson Fung
that categorize access by their access type (global memory read/write, local memory read/write, instruction read, ... etc.). [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 15784]

2014-08-14Fixed at least one error in the valgrind build. Forgot to initial a member ↵Tim Rogers
variable. I thought the init() function where dynamic_warp_id is initialized was called on construction. It is not. Added a default value in the constructor. Maybe a code review would have caught this :) Also cleaned up some weird code I had in the ptx_instruction::to_string(). Also trimmed out tabs from our stored source line string so it is much more readable on print [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 15310]
