- 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.

This requires decoupling updating the stats from printing them and modifying the printing code to accomodate this change.

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.

Parameters are finalized at kernel launch, which means the contents
of parameter memory are initialized. Kernel arguement names have a
fixed order, hence same address should be assigned on subsequent
kernel launches of same kernel in other streams provided the data size
param_t::size of arguments for each kernel launch is identical (an
assertion has been added to check this is true).
- passing regression

OpenCL)
This changelist adds full support for streams supported by a new class,
stream_manager and enables concurrent execution of kernels from different
streams.
- fast_regression.sh fails for simpleMultiCopy, simpleStreams (other tests
passing)
** Known issues **
- Kernel parameter passing is not done correctly for concurrent kernel execution
(somehow concurrentKernels is not affected by this): the parameters are
stored inside function_info, which is shared among parallel kernel launches
so that the values passed into the launch are likely to get overwritten if
multiple grids are launched in parallel streams.
- Statistics are printed out whenever the simulation thread runs out of
cuda commands (doesn't make sense to print out when a kernel ends during
concurrent kernel execution). This will probably require further tweaking
so as to be more compatible with data collection scripts.

stalling to send four requests per warp into L1T tag lookup.
If L1T is really 32B blocks (as per Henry's paper), this suggests
banking of L1T needs to be modeled.

2. clock memory pipeline no. subwarp times for each shader clock and increase
rob-size for texture cache (trying to improve correlation, currently at 0.9218)
3. start to modify shader stats to add back features for visualizer (warp
divergence distribution kind of working again)

passing CUDA 3.1 and ptxplus correlation, but correlation still bad (0.62)...
after debugging 1 to get it working with ptxplus, problem is very clear:
shared and constant cache accesses not occuring for operations that combine these with ALU operations.
TODO:
have a "read-operands" stage, which somehow combines operand collector
register reading with shared and const memory accesses...

- read only cache model with integrated mshrs (no L1D, yet); new
cache interface should be easily extendable to support texture
cache with latency fifo and separate tag/data arrays, though
this is not yet added (currently tags and data arrays are not
decoupled for texture)
- new partition model using the above
removes all old MSHRs, L1D etc...

(and parse it before creating the simulator objects).
2. creating core_config to hold only features of a shader_core that are high
level enough either (a) the functional simulator needs to know about them,
or (b) they affect memory *access* generation.
3. in config files only (so far) separate out notion of write-{through,back},
from notion of when a line is allocated... will use this to distinguish
different types of caches.
