icnt_config_islip.txt to use icnt_config_islip.icnt. This will not affect any of the regressions/correlations as they overwrite this with the correct configuration file name. Reviewed with Myrice.

*fixed typos in the XML file
*update the coefficients based on the latest bug fix, results in most caches scaling coefficients to drop by 2x.

to scale. Jingwen discovered the bug by looking at the regression results. He could not submit the fix due to tunneling problems.

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

replication, implemented write allocate / write back policies in L2 cache, added configurable parameters in gpgpusim.config ("W" = Write Allocate, "N" = No write allocate -> "P" = Private, "S" = shared), modified the cache configuration lines to always be separated by ":" instead of ":" and ",", and modified L1 and L2 data cache to be "Write Back" caches instead of "Read Only".
Still need to implement Ahmed's sectored cache implementation.

-Adding TeslaC2050 configuration: this configuration was initially integrated in the power branch from fermi-boktor branch to get IPC correlation with the Tesla card on Inder pc (pc-12). The IPC correlation data on the public wiki uses this configuration. The latest update for dram GDDR5 configuration Wilson added is also integrated.

- 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.

- 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

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.
