am stopping this by gaurding against it in the same way we do for updating the stat counts (checking if we have executed any cycles before printing). I am not sure what this does to CDP stat prints - as I am not sure what CDP kernels so to sim_cycles.... However EVERY other app except CDP is spewing junk to the output and it really messes up any per-kernel stat collection scripts.

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.

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.

undone in CL 12023 probably by mistake.

- Updated PTX parser to support CUDA 4.1 and 4.2.
- Revised fatbin workaround to a more robust version (with comments explaining it).
- Added print_simulation_time() in gpgpu_sim_thread_concurrent().

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.

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.
