Dear Professor,

when I tried the following command,

hotspot -c ../hotspot.config -f ../floorplan/abc.flp -p abc.pptrace -o
abc.ttrace -steady_file abc.steady

it gave the following error

error: inordinate floorplan size!


What could be wrong?. Pl help.

"Inordinate floorplan size" typically means that the spreader and/or the 
heatsink size have been configured to be smaller than the area of the 
floorplan.

Dear Prof.,
     Can I tune Hotspot to accept a power trace in nano watts? If
possible, how?

Hi,

You can hack inside HotSpot code (probably hotspot.c, but there may be other
places you need to change as well) by dividing the power numbers read from
the input power trace by 10^9.
The easier way would be just to convert to watts in your power trace file
using a script .

Dear Prof.,

when i tried hotspot -c hotspot.config -f abc.flp -p abc.pptrace
-steady_file abc.steady i got message

hotspot: util.c:165: dmatrix:Assertion `m[0] != ((void *)0)` failed.
Aborted


Is it because the dynamic memory allocation (util.c) has a limit on the
number of blocks the tool can accept? If so, is there a way that I can
increase the number of blocks the tool can accept?

Hi Krishna,

I guess it meant to be "rotatable" so that the direction of the block can be
changed. If you have further questions regarding this, please let us know.
As for the aspect ratio, you can try to make it to 5.0, although I wouldn't
recommend to do so, because unless you are modeling something like a cache
line or register file entry, AR > 5.0 is uncommon. If you are sure the
structure you model has that aspect ratio, then you can use it. HotSpot
should be able to internally divide it into subblocks with AR close to 1.0
to improve the accuracy of the results.

(By the way, if you don't mind, please also cc the mailing list (
hotspot at cs.virginia.edu) in the future, so that it also helps people who
have similar questions and your questions may get faster and better
responses from other HotSpot users.)

Hope this helps.

-Wei

Maybe your browser doens't have plugins for SVG? Have you tried to view
other SVG files that are not generated form HotSpot release?

Dear Prof.,
     I used the tool with ambient temperature 273.15 Kelvin. But I see
some negative temperatures like -50 degree Celsius in temperature
trace file. The maximum temperature generated is about 6 degree
Celsius. These are the temperatures generated by combinational gates.
Why do I get negative temperatures, below ambient temperature?

Hi,

What was your initial temperature? It should also be set in Kelvin.

Hey guys,

I just download the HotSpot 5.0 recently and I am new to Linux.I tried to
compile the HotSpot 5.0 in my school's Linux Machine but keep geting the
following errors: "make: Fatal error in reader: Makefile, line 51:
Unexpected end of line seen." I also tried wtih HotSpot 4.2 in addtion to
re-configure the GNU make, and I still got these errors.

Does anyone compile the HotSpot 4.2 or 5.0 recently? or does anyone know why
I got these error messages?

Hi Bo,

line 51 lies within a Makefile conditional.
It could be that your make does not understand the conditional directive.
As far as I can see, you need GNU make to compile Hotspot (called gmake on some systems).
I compiled Hotspot 4.2 and 5.0 successfully with the following version of make:

Subject: [Hotspot] Power values from cacti
Message-ID: <517638.48542.qm@web54205.mail.re2.yahoo.com>

Hi,
   I am using cacti 6.0 for the dynamic power, lkg power and area estimation of register file, Issue queue, ROB etc with the technology files from ITRS. The power values are very small for the cacti and the average power density of most of the components is in the range of 0.7 W/mm2. I have generated a floorplan using cacti area model. By running cycle accurate simulation for the single core, I get very less temp values. I do not know how to address this problem. I want to address the thermal issue in my experiment by using some microarchitectural techniques. But the avg temp is the range of 45.7 close to ambient temperature. There is significant reduction in power but not equally reduction in temperature. 

Is the problem due to very small area of the core and the heat sink model is large or should I change the package properties.

Is there any method to cope with this issue. Should I multiply the power values of each component with a constant value of 10 so that power density is 7 W/mm2. 


regards,
Fazal Hameed
