2014-08-14A much easier way to attempt to fix the problem targeted by CL12362 is to ↵Andrew M. B. Boktor
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. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12366]
2014-08-14When a kernel is done, it doesn't mean it finished executing. Instructions ↵Andrew M. B. Boktor
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.

2014-08-14Fixing a potential problem.Andrew M. B. Boktor
Right now this doesn't cause any trouble becaue increment_thread_id guarantees that this particular part of the condition is never false (in correct operation) Normal kernel configuration have the z dimention smaller than the x dimention which causes it to be always true, but with a weird configuration, this is a potential place for failure. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12357]

2014-08-14Removing some bottlenecks that limit that peak-IPCAndrew M. B. Boktor
- FUs depended on the result bus to know if they are going to be used on a certain cycle, this is not the case anymore, occupied bitvectors are added - A configurable number of result buses is added (the number of buses is equal to the EX_WB pipe width) - Modified the Fermi config file to add two ports to the operand collector IPC with a theoretical limit of number_of_SMs*64 is achievable using this configuration [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12349]

2014-08-14Adding configurable instruction latencies and initiation intervalsAndrew M. B. Boktor
The observed latencies are reduced by 5 to account for other stages in the SM pipeline Eventually this should be calibrated against the microbenchmarks [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12310]

[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 12025]
2014-08-14This changelist implements the following:Andrew M. B. Boktor
1. Adds support for using cuobjdump for both ptx and ptxplus execution. This has been tested with CUDA 4.0 . Ptxplus is no longer supported through decuda/decuda_to_ptxplus 2. Adds support for converting the SASS output by cuobjdump to ptxplus. This has been tested with CUDA 4.0 . The old path that extracts ptx from cubin files is still preserved 3. Adds a bank group model. (WARNING: memory config has changed, please adapt yours). To disable the bank groups model, set nbkgrp to 1 and tCCDL and tRTPL to 0 Diff the configuration files to learn about how to use those new options.

2014-08-14Integration change. Fixing bug for #149: A pathological case that caused LD ↵Wilson Fung
instructions to be over counted when the LD instruction is stalled for a long time after sending part of its memory requests. Those memory requests manage to return before the LD is done sending all of its requests. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 11888]

2014-08-14Changed arch_rech type to store 16 registers, 8 input and 8 output. 8 inputs ↵Inderpreet Singh

partitions will not lead to address aliasing. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 11574]

MAX_THREAD_PER_SM. Also decreased LOCAL_MEM_SIZE_MAX to 8kB to make it fit within our allotted memory space (otherwise the simulator may mistaken global memory access as local memory accesses). [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 11520]
