RE: Python syntax question
Sir,
I was just wondering that the module that you are utilizing (Rpyc) is a remote
process call module for python? Is this what you are developing with at this
time?
Thanks,
David Blubaugh

What's the syntax problem?
That's Python 3.0 syntax where ``print`` is not a keyword anymore but
a function. Won't work with Python 2.5.

HARD REAL TIME PYTHON
To All, I have done some additional research into the possibility of utilizing Python for hard real time development. I have seen on various websites where this has been discussed before on the internet. However, I was wondering as to how successful anyone has truly been in developing a program project either in windows or in Linux that was or extremely close to real time constraints? For example is it possible to develop a python program that can address an interrupt or execute an operation within 70 Hz or less?? Are there any additional considerations that I should investigate first regarding this matter??

Python for the Playstation 3
To All, I was wondering if there is still a community effort to develop Python for Linux distributions for the Sony Playstation 3?? I have found a few WebPages stating this effort to port Python in such a way to take advantage of the Cell architecture within the playstation? However, all of these WebPages are severely dated back as far as 2005-2006, with absolutely no additional activity since that time. I believe these WebPages are now abandoned. Is there any interest within the Python development team to port the Python language to the cell processor?? If not, I could try!! Anyone else interested in developing the playstation 3 into a powerful supercomputer for the common individual??? I am also interested in developing clusters of playstations for HPC by taking advantage of Python's support for RPC and MPI!

I can pack and unpack a float into a long e.g.

Any suggestions?
One alternative to using struct is to use math.ldexp
and math.frexp:
m, e = frexp(pi)
m
0.78539816339744828
e
2
int(m*2**53)
7074237752028440L
Then you can do your bit twiddling on int(m*2**53),
before using
ldexp to 'repack' the float.
Ah, those are handy. Jeff described his problem: In
particular, I
would like to round my float to the n most significant
bits.
I think this works:
from math import frexp, ldexp, floor
def round_mantissa(x, nbits):
shifter = 1 nbits
(m, e) = frexp(x)
m = floor(m * shifter + 0.5) / shifter
return ldexp(m, e)

Thanks for the help - your function seems to fit the
bill even better
than gmpy since I don't need an external module. In my
case I'll use m =
floor(m * shifter) / shifter instead of m = floor(m *
shifter +
0.5) / shifter

If I am not making any sense, please inform me as soon as possible. Don't do that from inside IDLE. These are some step by step generic instructions to install a new package; they don't assume much about your previous knowledge. 1) Open a command prompt window (or system prompt, or console, or...). Go to the Start menu, click on Run, type cmd (without the quotes), press Enter. 2) See if you can invoke Python directly; type at the command prompt: C:\doesntmatter python -V (use a capital V, press Enter at the end. Don't type the text at the left of the sign). You should get a response like this: Python 2.5.1 If you get a similar response (maybe a different Python version), skip to step 5. If you get an error message telling that python isn't recognized as a command or something, continue on step 3. 3) Let's try to find where Python is located. As you appear to have IDLE installed and working, open it, and execute these two lines: import sys print sys.executable c:\python25\pythonw.exe Take note of the response, but omit the last w. We will call this the full path to python.exe. In the example above, the full path to python.exe would be c:\python25\python.exe 4) Repeat step 2 above, using the full path to python.exe instead of the bare word python: C:\doesntmatter c:\python25\python.exe -V [press Enter] Python 2.5.1 You should get the installed Python version number, not an error. 5) Decompress the package you want to install into any temporary folder -it doesn't matter where- using your favorite tool (WinRar, WinZip, 7zip, the Zip file handler built into WinXP...). Probably you've already done that. Take note of the temporary folder (should contain the setup.py script) 6) Come back to the command prompt and make that temporary folder your current directory, using the cd command. E.g. if it were c:\temp\mypackage-3.2, type: C:\doesntmatter cd c:\temp\mypackage-3.2 [press Enter] c:\temp\mypackage-3.2 7) Now execute: c:\temp\mypackage-3.2 python setup.py install [press Enter] (If you had to go thru steps 3 and 4 above, replace the word python with the full path to python.exe) This should start the package installation; read its documentation for further details. -- Gabriel Genellina This e-mail transmission contains information that is confidential and may be privileged.

SAGE for FPGA development
Bill, The potential idea that I had in store for SAGE would be to first be able to develop complicated algorithms onto hardware. What I mean by this is to take for example, a FFT and then be able to map the entire algorithm into hardware, in a reasonable amount of time.

From what I can gather from the MyHDL website, the package allows one to specify silicon using python (converting the python to verilog code). That seems like a powerful tool for designing silicon, but I can't quite see why one would put this in SAGE. Yes, one would then be able to specify silicon circuits in SAGE, but that's not going to allow SAGE to run on FPGA's. To make it useful, one would then need to modify some of the underlying packages in SAGE, such as GMP, so that they run through the FPGA. Alternatively, one would need to program specific fundamental SAGE functions using MyHDL, then modify the higher level SAGE functions to call them if an FPGA was available. So I guess my question is, if MyHDL were in SAGE, who would actually use it to specify silicon and then use that silicon functionality to do mathematics? I note that you work for Belcan. Do you yourself have exertise in using MyHDL? What would you be able to contribute? Do you have a particular application in mind that you'd like to code for SAGE using an FPGA?

RE: SAGE for FPGA development
Bill, Let me first say that my FPGA experiences are of the following nature: 1.) Developed control algorithms onto a FPGA that were utilized to control a switch-reluctance motor (three-phase as well six-phase). 2.) I am currently in the process of developing a specialized Multidimensional FFT processor that can be utilized to determine the frequency content and angle of arrival of a target via a linear sensor array. I believe that you are deeply mistaken about that I would be the only person to use such a system. The FPGA market will only increase as more embedded systems utilize more and more FPGAs for the processing needs, since embedded system are being task with more computationally intensive tasks, such as for example, image digital signal processing within portable digital cameras. Electrical and Computer Engineers could start to utilize SAGE for system programming and development, not just only mathematicians or physicists doing their own selected work. Also, I think that you may have the wrong idea of porting SAGE to be executed within a FPGA. What I had in mind was to have MyHDL embedded within SAGE, where sage could handle the graphical plot outputs of what is being generated by MyHDL. To be absolutely clear, SAGE could be used to handle the graphs for the simulation side of what the logic that is being generated by MyHDL embedded within the SAGE framework. This could help in testing algorithms as they are being generated into verilog FPGA logic, by having a graphical experience within the entire development process. If you have any more additional questions, please contact me as soon as possible.

Is there a large group of mathematicians who have access to FPGA hardware? Also, you didn't answer my question about what expertise you have. William Stein is the maintainer of SAGE, so he would be able to say more about what fits with the design goals of SAGE, but my feeling is that something would only be added to SAGE if it were going to benefit a large base of its users (or bring a large base of users to SAGE). At this point I only see one person who might potentially use this, i.e. you. Sorry to seem a little discouraging, but I need a little more information to launch into a massive project to put FFT's onto FPGA's for use in SAGE. I mean, can I reasonably afford an FPGA which would be big enough for this and which I can put into my own home computer? Is this the way of the future for mathematicians?

MyHDL project for FPGA development!
Dan, Thank you very much for your reply. My Master's thesis is for Wright State University and is of the following nature: I am currently engaged with a Masters project, that utilizes a linear array of isotropic sensors, or in my case electromagnetic antennas. I am trying to develop a specialized Multidimensional FFT processor, that can determine the angle of arrival and frequency content of a perceived target with respect to the position of the linear array. I should further state that this Multidimensional FFT processor is currently of only two dimensions. Therefore, the MDFFT will only have a result of frequency value versus angle of arrival of the target with respect to the position of the linear array. There is a great deal of mathematics that are involved (SciPy), especially considering that in order to model the two-dimensional signal of the linear sensor array, I have to utilize concepts borrowed from differential geometry. This is why I will need to utilize a toolset like SciPy with python. I would still like to include the ImpulseC environment, since the environment does provide an interesting connection between FPGA hardware and software running on embedded processors ,such as the Power PC on Xilinx FPGAS. I believe that a marriage between Python, ImpulseC, MyHDL, SciPy, Gene Expression Programming, and GNU Plot will develop into a very interesting and powerful algorithm development environment for FPGAS. I will also need a way to develop floating-point hardware, since I will need to have the dynamic range of floating-point in order to determine the angle of arrival of targets placed many miles away from the linear sensor array. This is why Impulse C should still be considered, since they provide the ability of generating efficient floating-point hardware. I have to go now, since I have to report for my employment duties. In conclusion, I would very much to continue development for a Python, Scipy, MyHDL combined. If there are any more questions, Dan, please contact me as soon as possible.
