DSENT (Design Space Exploration of Networks Tool)
|
||||
|
||||
===============================================================================
|
||||
Overview
|
||||
===============================================================================
|
||||
DSENT is a modeling tool designed for rapid design space exploration of both
|
||||
electronical and emerging opto-electrical networks-on-chip (NoC). It provides
|
||||
analytic and parameterized models for various network components and is
|
||||
portable across a range of technology assumptions. Given architectural-level
|
||||
parameters, DSENT builds the specified models hierarchically from electrical
|
||||
and optical building blocks and outputs detailed power and area estimates.

===============================================================================
|
||||
Build (installation)
|
||||
===============================================================================
|
||||
To build DSENT:
|
||||
|
||||
% make
|
||||
|
||||
By default DSENT is built with logging disabled. Logging keeps track of what
|
||||
happens while running DSENT. It is an option more for the DSENT framework and
|
||||
DSNET models developers. If you want to enable this option, simply type the
|
||||
following:
|
||||
|
||||
% make LIBUTIL_IS_LOG=true
|
||||
|
||||
To clean the build:
|
||||
|
||||
% make clean
|
||||
|
||||
|
||||
===============================================================================
|
||||
Usage
|
||||
===============================================================================
|
||||
DSENT builds models and runs based on the specified configuration file. In the
|
||||
configuration file, you specify a model name and necessary information
|
||||
(parameters and properties) required to build the model.
|
||||
|
||||
To run DSENT:
|
||||
|
||||
% ./dsent -cfg <config_filename>
|
||||
|
||||
To check what models are available:
|
||||
|
||||
% ./dsent -available_models
|
||||
|
||||
To overwrite the configuration file from command line:
|
||||
Use ';' to separate different key/value pairs.
|
||||
|
||||
% ./dsent -cfg <config_filename> -overwrite <new query string>
|
||||
% ./dsent -cfg configs/example.cfg -overwrite "NumberInputs=5; NumberOutputs=6;"
|
||||
|
||||
To print out in a more human-friendly fasion:
|
||||
|
||||
% ./dsent -cfg <config_filename> -verbose
|
||||
|
||||
To check what options are available:
|
||||
|
||||
% ./dsent -help
|
||||
|
||||
Please see configs/example.cfg for an example of a configuration file.
|
||||
|
||||
Please see configs/router.cfg for the router configuration file.
|
||||
|
||||
Please see QueryString and EvaluateString specifications below to know more
|
||||
about the usage.
|
||||
|
||||
===============================================================================
|
||||
Advanced Usage
|
||||
===============================================================================
|
||||
Since DSENT is a generic modeling framework for electrical and optical
|
||||
components, you can create your own models. We will release guidelines on how
|
||||
to create custom models on top of DSENT framework. You can use the provided
|
||||
models as references.
|
||||
|
||||
|
||||
===============================================================================
|
||||
Quick start for Orion users
|
||||
===============================================================================
|
||||
Instead of using the SIM_port.h file, DSENT uses a text-based configuration
|
||||
file to specify the router/link configurations. You do not need to recompile
|
||||
if you change parameters. Even though we use different parameter names, the
|
||||
ones we use should be self-explanatory. In this package, we provide template
|
||||
configuration files for the router and link:
|
||||
|
||||
router - configs/router.cfg
|
||||
link - configs/electrical-link.cfg
|
||||
|
||||
Technology
|
||||
----------
|
||||
We currently support 45, 32, 22, 11nm. You can specify the desired
|
||||
frequency but not the nominal voltage level since it is normally
|
||||
fixed in different processes.
|
||||
|
||||
Router specs
|
||||
------------
|
||||
Currently we only support the model of a widely used 3-pipeline-stage
|
||||
input-buffered virtual channel router and does not have distinction
|
||||
from ports for different components (cache, memory controller, I/O).
|
||||
|
||||
Input buffer specs
|
||||
------------------
|
||||
The number of virtual channels used for different message classes
|
||||
might be different; hence, DSENT uses NumberVirtualNetworks to
|
||||
specify the number of message classes and use
|
||||
NumberVirtualChannelsPerVirtualNetwork and
|
||||
NumberBuffersPerVirtualChannel to define the buffers needed for a
|
||||
virtual network (message class).
|
||||
|
||||
Currently only DFF-based RAM is supports. This is reasonable since
|
||||
normally the buffer space needed at input port is small enough and
|
||||
does not need to use SRAMs or RFs (register files).
|
||||
|
||||
Crossbar specs
|
||||
--------------
|
||||
Currently DSENT only supports multiplexer-based crossbars
|
||||
(MULTREE_CROSSBAR). You no longer need to specify the degree of the
|
||||
multiplexers.
|
||||
|
||||
Switch allocator specs
|
||||
----------------------
|
||||
DSENT models a two-stage switch allocator. The first stage is used to
|
||||
arbitrate between VCs in the same input port, and the second stage is
|
||||
used to arbitrate between input ports. If there is only one VC in
|
||||
the input port, then the energy/power/area cost for the first stage
|
||||
will be zero.
|
||||
|
||||
Currently, DSENT supports MatrixArbiter.
|
||||
|
||||
VC allocator specs
|
||||
------------------
|
||||
We assume that the router uses a VC select scheme where the VC
|
||||
allocation is done by just popping a FIFO. Currently DSENT ignores
|
||||
this module since the FIFO that needs to keep the free VC information
|
||||
should be small enough.
|
||||
|
||||
Clock distribution specs
|
||||
------------------------
|
||||
Currently DSENT provides a broadcast H-Tree model. You can specify
|
||||
the number of levels of the H-Tree (normally 4 or 5 levels should be
|
||||
enough).
|
||||
|
||||
DSENT replaces the original orion_router_power, orion_router_area and
|
||||
orion_link with QueryString and EvaluateString (see below for more detailed
|
||||
information on how to use them).
|
||||
|
||||
|
||||
===============================================================================
|
||||
QueryString specifications
|
||||
===============================================================================
|
||||
DSENT is a query-based model evaluator. You use QueryString to specify what
|
||||
information you want DSENT to output. The syntax of a query string is shown as
|
||||
follows:
|
||||
|
||||
[Query type]>>[Instance name (with hierarchy)]:[Sub query type]@[Detail level]
|
||||
|
||||
E.g., Area>>Router->Crossbar:Active@4
|
||||
* Query type: Area
|
||||
* Instance name: Router->Crossbar
|
||||
* Sub query type: Active
|
||||
* Detail level: 4
|
||||
|
||||
Query type
|
||||
----------
|
||||
There are 9 types of queries: Parameter, Property, Energy, NddPower,
|
||||
Area, InstHier, EventHier, NddPowerHier, AreaHier.
|
||||
|
||||
Parameter - Print the model parameters needed to be specified
|
||||
Property - Print the design constraints or utilization
|
||||
Use these to check what needs to be specified in the configuration
|
||||
file for the model. No sub query type is needed for these two
|
||||
types.
|
||||
|
||||
Energy - Print the data-dependent energy cost of an event
|
||||
NddPower - Print the non-data-denepent power of an instance
|
||||
Area - Print the area cost of an instance
|
||||
Use these to obtain the costs of the specified model.
|
||||
|
||||
InstHier - Print the instance name hierarchy
|
||||
Use this to know what sub-instances are built for this model
|
||||
|
||||
EventHier - Print the available events for Energy queries
|
||||
NddPowerHier - Print the available non-data-dependent power types
|
||||
AreaHier - Print the available area types
|
||||
Use this to know what to specify in the "sub query type" field.
|
||||
|
||||
Instance name (with hierarchy)
|
||||
------------------------------
|
||||
The (sub)instance that you want to perform query. The name should be
|
||||
hierarchical starting from the top level model. Hierarchies are
|
||||
separated by the symbol "->".
|
||||
|
||||
Sub query type
|
||||
--------------
|
||||
This field is not required for 'Parameter', 'Property' and 'InstHier'.
|
||||
|
||||
For 'Energy', this field stands for the event that cause this energy
|
||||
cost, such as 'WriteBuffer'.
|
||||
|
||||
For 'NddPower' and 'Area', this field stands for the power and area
|
||||
cost of the model, such as 'Leakage' and 'Active'.
|
||||
|
||||
For 'EventHier', if this field is not specified, all events of this
|
||||
instance will be printed; if this field is specified, then only
|
||||
the specified event will be printed. 'AreaHier' and 'NddPowerHier'
|
||||
also have the similar behavior.
|
||||
|
||||
Detail level
|
||||
------------
|
||||
Defines the hierarchy depth to be printed. '0' means current level.
|
||||
This field is needed for all query types for syntax correctness,
|
||||
although it is not used for 'Parameter' and 'Property'.
|
||||
|
||||
Multi-line queries
|
||||
------------------
|
||||
Query strings specified across multiple lines in the config file
|
||||
must have each line be terminated by a '\'. It is whitespace sensitive,
|
||||
so make sure there are no spaces after '\'. Note that the parser
|
||||
prunes everything after the comment '#' character, including '\'!
|
||||
See configs/router.cfg as an example.
|
||||
|
||||
Examples of individual QueryString's:
|
||||
|
||||
Parameter>>Router@0
|
||||
Property>>Router->Crossbar@0
|
||||
InstHier>>Router->InputPort@2
|
||||
Energy>>Router:WriteBuffer@2
|
||||
NddPower>>Router->Crossbar:Leakage@3
|
||||
Area>>Router->SwitchAllocator:Active@4
|
||||
|
||||
|
||||
===============================================================================
|
||||
EvaluateString specifications
|
||||
===============================================================================
|
||||
DSENT provides a way to let users do custom calculations by specifying the
|
||||
EvaluateString in the configuration file. EvaluateString constains a sequence
|
||||
of statements separated by one ';'. DSENT reads through the sequence and
|
||||
evaluates the statements one-by-one.
|
||||
|
||||
Currently, DSENT supports:
|
||||
Four arithmetic operations
|
||||
--------------------------
|
||||
3 + 4 * (5 + 6) / 7;
|
||||
|
||||
Define local variables through assignments
|
||||
------------------------------------------
|
||||
variable 'a' will be mapped to 7 for future referencing
|
||||
|
||||
a = 3 + 4;
|
||||
|
||||
Global variable referencing
|
||||
---------------------------
|
||||
$(var_name) indicates either a key in the configuration file or a
|
||||
query string. If var_name exists in the configuration file, then the
|
||||
corresponding value will be returned; otherwise, DSENT will do a query
|
||||
using the string var_name@0 and return the query result.
|
||||
|
||||
b = $(Energy>>Router:WriteBuffer) * $(Frequency);
|
||||
|
||||
Printing outputs
|
||||
----------------
|
||||
DSENT prints the string following the keyword 'print'.
|
||||
|
||||
print <expression>
|
||||
print "<string_to_print>";
|
||||
print "<string_to_print>" <expression>;
|
||||
|
||||
print 3 + 4; # Output: 7
|
||||
print "Hello World"; # Output: Hello World
|
||||
print "Hello World " 3 + 4; # Output: Hello World 7
|
||||
|
||||
Multi-line evaluate strings
|
||||
---------------------------
|
||||
Evaluate strings specified across multiple lines in the config file
|
||||
must have each line be terminated by a '\'. It is whitespace sensitive,
|
||||
so make sure there are no spaces after '\'. Note that the parser
|
||||
prunes everything after the comment '#' character, including '\'!
|
||||
See configs/router.cfg as an example.
|
||||
|
||||
|
||||
===============================================================================
|
||||
Units
|
||||
===============================================================================
|
||||
DSENT uses only SI units for all inputs and outputs. For example:
|
||||
time = s (second)
|
||||
distance = m (meter)
|
||||
capacitance = F (Farad)
|
||||
power = W (Watt)
|
||||
energy = J (Joule)
|
||||
resistance = Ohm
|
||||
loss = dB (Decibels)
|
||||
|
||||
|
||||
===============================================================================
|
||||
Known Bugs and Issues
|
||||
===============================================================================
|
||||
|
||||
1. If timing is not met, the timing optimizer will put the model in a state
|
||||
where everything is the maximum size (huge power, area). Thus, model results
|
||||
can be considered a gross over-estimate when timing isn't met. This is just the
|
||||
nature of the greedy timing optimizer and it will be addressed in the future.
|
||||
|
||||
2. The VC control and credit buffer component of the router is currently
|
||||
not modeled, as they have always been assumed to be lumped into the "negligible
|
||||
control cost" category in previous models and evaluations. Our recent
|
||||
experiments have shown that this is not true and we will be adding this in the
|
||||
next iteration.
|
||||
|
||||
3. Some of the connectivity paths have not been checked thoroughly. Thus,
|
||||
timing optimizer may miss some of the paths. However, we tried to make sure
|
||||
that the critical paths are modeled properly.
|
||||
|
||||
4. Local interconnect will have an ever-larger impact on power and timing as
|
||||
technology scales. So far we have not implemented a method for automatically
|
||||
estimating them but we will eventually address this. Evaluations for 22nm
|
||||
and below will tend to underestimate as a result.
