Subject: [Hotspot] 2 D mesh floor plan
Message-ID: <1357672858.12196.YahooMailClassic@web164001.mail.gq1.yahoo.com>


Hi everbody,
first i want to say happy new year to u. 

second i have a question to u.

i use the 

Floorplan close
to the Alpha EV6 processor



 generated by hot spot tool and? used by VARIUS model.
?in this floor plan each? component is refrenced by left-x and bottom y


# Floorplan close
to the Alpha EV6 processor

# Line Format:
<unit-name>\t<width>\t<height>\t<left-x>\t<bottom-y>
i wonder how can they reference a component with single x and single y points?
when i try in analogy to generate a 2x2 mesh with link length Lr2(L,0)
0------0|????? |r1(0,L)
|r3(L,L|? 
0------0?r4 (L,L)
i found that taking the right upper node as the origin
and writing the left-x and bottom y of each link of the meshi will find r3 and r4 to have same coordinate!!!
when u used hotspot to generate floor plan, did u face similar issues??? can you? advise me on how to discriminate such
 symmetry,known that i use? VARIUS model on that floor plan? 

thanks and best regardsEman

Hi,

HotSpot uses 4 values to specify the location of each block: block width,
block height, left x-coordinate and bottom y-coordinate fo the block. The
origin of the entire floorplan is always (0,0) at lower-left corner.

So if you have a floorplan with four square block at each corner with side
length of L, your floorplan would look like this:

Block-LowerLeft L L 0 0
Block-LowerRight L L L 0
Block-UpperLeft L L 0 L
Block-UpperRight L L L L

hope this helps.

-Wei

Subject: [Hotspot] Using ArchFP
Message-ID: <CAMjuK3ZidL6=kXpPOd_zWZpHgsiD0WyGBANL9suVDaCKjuYNxg@mail.gmail.com>

Some people have sent in email asking how to use ArchFP, our pre-RTL
floorplanning tool that is part of the hotspot suite of tools.  Therefore,
I thought I would send this out to a wider audience to try to clarify a few
issues.

ArchFP does not have a GUI or a declarative input language, but instead is
essentially a C++ class library.  There is a not a user guide per se, but
both the ArchFP Techical Report and the VLSI-SoC conference paper give
extensive descriptions of the classes and the methods on them.  You can
find links to those papers, as well as the ArchFP software for download,
here:

http://lava.cs.virginia.edu/archfp/

You can instantiate ArchFP classes to make floorplans by including the
library into your own code, or you can modify the Main.cpp to make
floorplans of your own design.  Main.cpp also contains extensive example of
ArchFP code used to generate various floorplans which can be used as
"starter code" to build your own designs.  ArchFP integrates with other
tools such as hotspot by both reading and writing hotspot file format.  One
can easily visualize an ArchFP floorplan by using the "hs2pdf" script that
is included with the download.  As the name implies, it converts the
floorplan in hotspot format into a pdf file, which you can then view with
the pdf viewer of your choice.  This also makes it easy to include drawings
of floorplans in documents by merely inserting the pdf into the document
file.

I hope this helps.

Hi Wei,
thanks for your reply. if the square represent 2x2 mesh with 4 switches at each corner, and i want the floor to refrence the interconnect not the switch, when i follow your arrangement? and refrecing each link by left x and bottom y , i found that
Block-LowerLeft L L? 0 0Block-LowerRight L L 0 0
Block-UpperLeft L L??? L0Block-UpperRight L L? 0L
?????? y
??????? ^
???????? |upper right
???????? 0------0?lower|??? ? ?? |upper
?left??? |???????? |? left

orgin 0------0--->x???????? lower right

so in my floor 2 links or squares lower left and lower right have same coordinate?
so what do u think?

thanks
Eman

Hi,

I don't quite understand what you are trying to floorplan here. It seems
you are trying to model on-chip network (in this case, 4 switches
associated with four cores)?

Please keep in mind that HotSpot requires that there be no overlap or blank
spaces in the floorplan, and every block has to be rectangle (or square).
So you'll have to floorplan the cores and the switches into different
blocks.

Not sure if I answered your question...

Dear Eman,

if you are trying to model the link connecting the on-chip routers, I think
it's not a good idea to include a block in the Hotspot floorplan, for
mainly two reasons: the links are generally on a different layer of the
chip, so at the end they would overlap (in third dimension) with the logic
floorplan; and second, the power associated to the communication should be
embedded in the drivers at the far end of the links, so you end up in
including them in the on-chip routers.

However, we use Hotspot and Varius with a script to automatically generate
any 2D mesh topology based on Alpha21364. I can share this with you if you
want

Cheers

Hi Wei,
u r right,trying to model on-chip network (in this case, 4 switches associated with four cores).
every link has width, height, and length. and 2 switches with the coordinates u mentioned by its 2 ends.
i am not modeling switches or cores, as i focus on the links. so do u find that not good with hotspot?

if i try to reference the link with left-x, bottom-y, i have the duplication i told u about, i can reference the links by one of the switches it is connected to, but i find my self using switches at the bottom or switches at left or right, no rule i mean.

can u help me on that?

thanks
Eman

HotSpot uses 4 values to specify the location of each block: block width, block height, left x-coordinate and bottom y-coordinate fo the block. The
 origin of the entire floorplan is always (0,0) at lower-left corner.?

So if you have a floorplan with four square block at each corner with side length of L, your floorplan would look like this:
Block-LowerLeft L L 0 0Block-LowerRight L L L 0

Block-UpperLeft L L 0 LBlock-UpperRight L L L L
hope this helps.

i found that taking the right upper node as the origin
and writing the left-x and bottom y of each link of the meshi will find r3 and r4 to have same coordinate!!!


when u used hotspot to generate floor plan, did u face similar issues??? can you? advise me on how to discriminate such
 symmetry,known that i use? VARIUS model on that floor plan? 

thanks and best regardsEman

Dear Simon,
i am assuming the NoC links are short and all of them are in same layers, about the drivers , i am embedding them with the switches, i.e at link ends. any way it will be very kind of u to share ur script with me.
thanks
Eman

Dear Eman, ?if you are trying to model the link connecting the on-chip routers, I think it's not a good idea to include a block in the Hotspot floorplan, for mainly two reasons: the links are generally on a different layer of the chip, so at the end they would overlap (in third dimension) with the logic floorplan; and second, the power associated to the communication should be embedded in the drivers at the far end of the links, so you end up in including them in the on-chip routers.
?However, we use Hotspot and Varius with a script to automatically generate any 2D mesh topology based on Alpha21364. I can share this with you if you want?Cheers

Hi,
I don't quite understand what you are trying to floorplan here. It seems you are trying to model on-chip network (in this case, 4 switches associated with four cores)?


Please keep in mind that HotSpot requires that there be no overlap or blank spaces in the floorplan, and every block has to be rectangle (or square). So you'll have to floorplan the cores and the switches into different blocks.


Not sure if I answered your question...

Eman, I'm still not sure I understand what the problem is. How are you 
generating this floorplan?  If it's a script, it seems you have a bug. 
If it's by hand, you simply need to manually ensure that the blocks have 
the proper x/y coords and height/width so that the resulting floorplan 
has no blank space and no overlapping blocks. This can be tedious, which 
is why I suggested ArchFP (which is not limited to processors - you can 
program any floorplan you want). Or you may find Simone's script useful.

(You can fill in regions of the chip that you don't care about with 
blocks that are assigned zero power in the thermal modeling stage -- but 
this will yield bogus thermal modeling results, unless those are truly 
whitespace in the final chip.)

Hi Keiven
thank u for this. u r right i am using a script to generate
 the mesh, i can fix it, if i understand how the hotspot floor plan 
links of 2x2 mesh. i am doing so only because VARIUS accept floor plans 
in hot spot like format. about your suggestion of using ArchP to 
generate a grid with dummy components. i found it easier to modify my 
script to generate mesh floor plan referencing the switches in the way 
Wei has generously explained to me. i simply need a clarification o how 
to reference the links, without having duplicate.

thanks alot for your willing to help me.

Subject: [Hotspot] Is hotspot restricted by chip dimension
Message-ID: <CAExgYKba7ZY_BQi=oRJ_jN+nSd3OKrYHCEDmMJQa2vWkr+_Azw@mail.gmail.com>

Hello,

I would like to know whether HotSpot has some limits about the chip
dimensions? I've test it with a chip in the size of 100x93 um and the
results are 45 for all floors.
Another thing that I'm concerned is about the power trace file, is that the
average power in W, or is the density i.e. the average power per sq.m or
sq.cm, because the results I'm getting using just W are always around 0,
and the same for all floors.

Best Regards,
Zdravko Georgiev

Hi,

HotSpot doesn't have limit on chip dimensions, although obviously chips
with zero dimensions wouldn't work.

Regarding your observation of uniform temperature on a tiny chip (100x93um
seems to be too small for a realistic chip), the results do make sense.
This is because of two factors: (1) the amount of power applied is small.
and more importantly (2) the lateral heat transfer is comparable to the
vertical heat transfer as 100um is comparable to or smaller than typical
silicon thickness.

Regarding power units in HotSpot power trace, it is in Watts. Again, the
nearly zero degree temperature rise is caused by the tiny amount of power
applied. A quick back-of-envelop calculation: if the power is 10mW (which
is probably already too high for an area of 100umx93um), with a very good
thermal package of 0.1K/W thermal reisistance, the average temperature rise
would be 0.001K.

Hope this helps.

Hi,

I was trying to simulate a vertically stacked IC, with totally 18 layers
specified in the LCF file. I am not using package model. I am also not
using the secondary heat transfer. So when I eventually print out all the
temperatures of all the layers, I see that there are totally 20 layers
instead of the expected 18. Why is that?

Hotspot is merely a library that models temperature as a function of a 
floorplan of blocks, where each block has a certain power dissipation. 
For transient simulations, the power value per block would of course be 
updated every time step.

So yes, in that sense, HotSpot can model multicore, GPUs, heterogeneous 
MP-SoCs, etc.  However, note that HotSpot only models temperature; you 
will need some power model. McPAT is quite popular for this.

For generating the floorplan, I would suggest you consider ArchFP.

Hopefully all the instructions you need for using HotSpot are on the 
website.

We would need more information to help you.

Regarding the constant temperatures, this depends on the power trace you 
are using and how you initialize the temperatures.

Regarding process-specific temperatures, are you using multiple 
concurrent threads?  If you simply mean that one process runs for a 
while, and you want to track it's temperature; followed by another 
process for which you want to track temperature -- you simply need to 
correlate the timestamps of the context switches to the temperature trace.

If you have multiple concurrent threads that are interleaved on a 
fine-grained basis, or even issuing in the same cycle (e.g., SMT), then 
your question is more difficult, because per-process temperature in this 
case does not have a physical meaning. You could, however, look at the 
heat load that any given thread adds by isolating its power dissipation.

You can create the floorplan any way you want, but ArchFP will probably 
simplify the task. In the end, you need a .flp file with the coordinates 
and sizes of the blocks.

Replicating a specific product is only possible to the extent that you 
can find out accurate information about that processor. In the past, we 
have sometimes resorted to finding a publication (in a review or 
academic paper that labels blocks on top of a die microphotograph) and 
measuring with a ruler! This of course trusts that the authors' labeling 
is precise enough for your purposes.

Hope this helps,
--Kevin

Hi Karthik,

HotSpot is a thermal "model" - which means it is a simulator. Given the
power numbers and floorplan information, it can simulate thermals. For your
purpose, if I understand correctly, you are looking for one of the two
following options:

1) Real thermal measurements from a real processor (or)
2) You have an OS simulator setup into which you can integrate HotSpot into.

If it is the former, you can read the CPU thermal sensor at runtime from a
Model Specific Register using tools such as http://openhardwaremonitor.org/

If it is the latter, a couple of options come to mind:

1) UCSC researchers used Athlon for their studies:
http://users.soe.ucsc.edu/~renau/docs/isca07.pdf
2) If you are looking for publicly available info (floorplan etc.) on Intel
CPUs, following come to mind:

a) ISSCC 2007 publication:
Sakran, N.; Yuffe, M.; Mehalel, M.; Doweck, J.; Knoll, E.; Kovacs, A.; ,
"The Implementation of the 65nm Dual-Core 64b Merom Processor," *Solid-State
Circuits Conference, 2007. ISSCC 2007. Digest of Technical Papers. IEEE
International* , vol., no., pp.106-590, 11-15 Feb. 2007
doi: 10.1109/ISSCC.2007.373610
URL:
http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=4242287&isnumber=4242241

b) die photos here:
http://www.intel.com/pressroom/kits/core2duo/#C2D

c) simple floorplan here:
http://www.intel
.com/technology/itj/2006/volume10issue02/art01_Intro_to_Core_Duo/p02_intro.htm

Apart from these, I am not aware of published floorplans for the core
microarchitecture. If you are looking for more detailed floorplan for an
x86 processor, P4 comes to mind:
http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.84.4146&rep=rep1&type=pdf


Hope this helps,
