2014-10-06Remove -a which appends dependences. This causes make process too long and ↵Myrice
dependency file too big without a make clean
2014-10-06Fixed mac build failsMyrice
1. ptx_sim.h::473, stack cannot use incomplete type "operand_info" which is a forward declaration. The reason is underlying implementation of stack is deque which need a complete type. It is better to remove forward declaration by break circular dependence for future fixes. It is also benefit unit test 2. shader.h::1334, this hack cannot pass clang. Clang does not allow a array with not a explicit size. Please fix this hack by correct implementation as soon as possible 3. The default parameter causes clang to fail because it frustrate the compiler. This is still under discussion whether such implementation is correct. http://stackoverflow.com/questions/18313509/default-argument-gcc-vs-clang. I changed it to two constructors to avoid confusion.

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.

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.
