Checking in the data footprint stats as reported in the micro paper. The implementation uses gpgpu pointer, due to which I don't feel fine pushing to mainline. May be I can do the stats check and increment in l2cache.cc through a public function to avoid exposing gpgpu pointer to public

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 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: 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.

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]
2014-08-14MergingTim Rogers
//depot/gpgpu_sim_research/fermi_tim/... to //depot/gpgpu_sim_research/fermi/... Integrating CLs up to 15295. Descriptions of these CL's are included. *** A couple changes to aeriel-vision for warp issue plot support *** More arielvision changes to support the variable-entry length stacked bar chart *** Properly printing the right resolution of dynamic warp ids ***. Generalized the scheduler code and added detailed statistics for which warps issue each cycle. Verified the execution of the LRR scheduler - still have to get the two level scheduler to work. *** Implementing the 2lvl scehduler has it has been originally coded. LRR on both the inner and outer levels *** Adding in a debug tracing system to GPGPU-Sim. I am sick of writing debug code - then having to comment out, ifdef out or delete it to checkin. This also allows for print streams so the user can decided which traces they would like to see. Every print in GPGPU-Sim should go through this system - then it will be really easy to only get the information you want and more importantly people will (a) write and (b) checkin code that actually profiles what they are building. Reading tracefiles is superiour in many ways to single stepping since you can print the world and just vet the logfile for what you need. This also fascilitates advice from the Debugging Rules! book which states that you should never throw away a debugging tool. Having debug prints that don't get thrown away is big. *** Allowing the trace to be specified in the Make. Run Make TRACE=0 to compile the code without any traces *** Allowing prints from the performance sim to get the actual ptx instruction text *** Getting the two level scheduler to actaully work... What is released in fermi does not work at all - it effectively performs "static warp limit" from my CCWS paper. Warps are never demoted from the active list since the functionality checking to see if they are waiting on a longop is completly broken. Maybe if the original author had access to the tracing functions this would not have happened. The islongop test was completely broken. It did not mark the register as used, it marked the register number in the instruction as used. For example if this instruction was creating a long op: ld r6 [r1] It would mark register 0 as waiting for a long op (since it is register 0 of the two registers in this instruction), not register 6. Additionally, whenever ANY instruction from a warp releases registers, ALL the longops being tracked for this warp get cleared.... The only way anyone ever thought this worked is if they did not test it.... *** Reworking the warp schedulers to share common code. Making the GTX480 use gto by default. I am not sure wht they really use, but it really can't be LRR. Also adding in a new file for custom shared trace defines. These are useful when you want a print that has some additional criteria or information printed. Verified that the schedulers all work to a first order based on traces. *** Making it so you can run the stats collection scripts from any directory. Also allow the caller to specify a stats file instead of just assume its always the same one [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 15296]
2014-08-14bug31Ayub Gubran
1. Renaming '-gpgpu_dram_sched_queue_size' to '-gpgpu_frfcfs_dram_sched_queue_size' 2. Updating the output not print that statistic out at all if the DRAM access scheduler is FIFO. 3. Adding "-gpgpu_dram_return_queue_size" option to specify the return queue size (defualt 1024). config files should take this change into account [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 15227]
2014-08-14Fixing L2 WriteBack bug caused by using the partition address for both set ↵Tayler Hetherington
index generation and storing tag/block address. - Added l2_cache_config class to extend the baseline - Allow custom set_index per cache. Modified L2 set_index function to use the memory partition address - Modified the cache tag to now be tag+set_index (same as the block address). Useful for more complex set index generation functions that can allow different indexes to map to the same set.

2014-08-14Added kernel name and launch uids to the stat printout to simplify ↵Wilson Fung
per-kernel stat binning. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 15109]
2014-08-141- it seems like using #ifdef within a class definition confuses valgrind, ↵Ahmed El-Shafiey
replaced this with defining an empty class if #GPGPUSIM_POWER_MODEL is not defined. 2- fixing the makefile to make it actually compiles if the #GPGPUSIM_POWER_MODEL is not defined. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 14858]

2014-08-14Updated the option parser to support named sub-options (via a separate ↵Wilson Fung
instance of option parser). Changed DRAM timing options to use this new format. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 14457]
2014-08-14Fix for bug 9: Now querying the state of the pdom stack in call_imp and ↵Ayub Gubran
callp_imp using a core_t function, thus moving the querying function into the abstract model of the core instead of shader_core_ctx which represents the performance mode. This code simplify the querying and also avoid the unnecessary calling hierarchy that was used. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13375]
2014-08-14Fixed GDDR5 parameters in Fermi config:Wilson Fung
- Increased burst length to 8 and changed address mapping to reflect 16 banks as suggested by Jungrae. - Decreased the DRAM clock to 924MHz from 1848MHz. - Corrected CAS Latency and Write Latency in the timing constraints. - Added a new option 'dram_data_command_freq_ratio' to configure the frequency ratio between the DRAM data bus and command bus.

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]
2014-08-14Changing the configs to be backward compatible by disabling bank groups by ↵Andrew M. B. Boktor

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.

2014-08-14Fixing bug 126. Now DXTC runs to completion by not giving correct result ↵Wilson Fung
(expected). The key is that the missing function is now in place. Also removed reference to print_shader_cycle_distro() (this is deprecated by AerialVision). [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 11346]
