2014-08-14Adding other power stats to reset functionTayler Hetherington
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 15522]
2014-08-14fixing bugs that were revealed by automated power correlation results.Ahmed El-Shafiey
1- reset the per kernel average power per component every kernel. 2- chage the font size of the x ticks in fial figure [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 15521]
2014-08-14fixing some assignment in the "get_operand_value" function where unsigned ↵Ahmed El-Shafiey
were assigned to unions! Also, do proper initialization in the constructors of operand_info, therse among places where valgrind complaining from NNC, but still it is not fixed. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 15503]

2014-08-14Okay, both the crash and the valgrind complaint are caused by the non-type ↵Tim Rogers
safeness of fprintf. Fix is to explicitly tell fprintf that the to_string.c_str() result is a string. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 15312]
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]
2014-08-14Fixing a bug exposed by the fix for bug 42.Tim Rogers
The "_" "null" register potentially generated by ptx and intentionally generated by ptxplus was being initialized without a type. This caused the parser to think it was not a register. Fix is to allow the parser to think of it as register, but ensure the arch-sim does not by adding a flag indicating that it is special.

//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]

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]

//depot/gpgpu_sim_research/fermi_locality/... to //depot/gpgpu_sim_research/fermi/... Adding in some protected constructors to the core cache classes. This allows us to customize caches (for example having them use a custom tag array) more easily. Also I made the in-class tag_array object in the baseline_cache into a pointer. This allows derived classes to easily create custom tag arrays. I think in general, class extendibility is increased when pointers are used instead of in-object storage.

2014-08-14Adding in a statistic for number of dynamic warps issued by their ID.Tim Rogers
Also fixing some really scary code that was memsetting the "*this" to 0. The code sort of worked since there was only one member on the derived class (that was never referenced) and it had no virtual functions. What I did to fix this is equally ugly, but far less dangerous. I get a pointer to the start of the "plain old data (pod)" section of the class then memset it to 0. Now the derived stats class can have more stuff on it than pod and we don't have to worry about stomping. The "right" fix here is to not derive from pod and just make it a member with an accessor. However, this is going to require all the client code to be re-written. [git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 15203]

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.
