MeTA update and recreational programming ;)

New MeTA Studio updates are available at: http://code.google.com/p/metastudio/

Features include:
a) subvolume generation and saving
b) Support for Fuzzy Volume generation
c) function value interpolation APIs
d) lots of improvements to UI and standard set of bug fixes..


To get a break of what i generally do, i am (re) learning a bit of windows programming and with it am writing a small set of C++ APIs for doing windows programming on my old Win98 machine. Its called weon and is downloadable from http://tovganesh.googlepages.com/weon.tar.gz

To create and open a window its as simple as:

include "weon.h"

CWeonApp app;

WEON_APP_MAP(app)

weon is under development and right now you cant do much with it. but i promise to make it simple to read and use :)

And with the help of APR and RK we have written a small set of APIs for doing MPI style programming purely using Python. Called pimpi its available from: http://tovganesh.googlepages.com/pimpi.tar.gz


A small test program that uses pimpi looks like this:

import pimpi
import sys

pimpi.init(sys.argv)
noOfProcessors = pimpi.size()
myRank = pimpi.rank()

print "Total number of processors: ", noOfProcessors
print "My rank: ", myRank

if (myRank == 0):
   for i in range(1, noOfProcessors):
       pimpi.send(i, "hi")
else:
   print pimpi.recv()

data = pimpi.bcast(0, "bhello")

print data, myRank

data = pimpi.bcast(0, repr((1,2,3)))

print data, myRank

pimpi.finalize()

To run the above code you use:
python pimpiboot.py test.py

Note that pimpiboot.py reads a file called "node.list" that contains the nodes which you want to use in parallel. You need to setup your cluster environment for password less rsh/ssh access for pimpi to work correctly.

... look back here for more updates on these codes :)
