[Radiance-general] parallel dctimestep

[Sarith Subramaniam]

Hi Santiago,

I pretty much did the exact same thing that you mentioned to run 
multiple instances of dctimestep with Python. The syntax is something like:

/import multiprocessing as mp/

/import os//
/

/#Run dctimesteps, 16 at at time./

/#runCommand is just a call to os.system
/

/#commands is a list of dctimestep commands like ["dctimestep dc.mtx 
sky0001.smx > res0001.smx", ///"dctimestep dc.mtx sky0002.smx > 
res0002.smx" ...]
//

/pools = mp.Pool(processes=16)/

/pools.map(runCommand, commands)/


For the above, you'd have to do some additional scripting to run rmtxop 
and compile all the results into a single file. There is also a method 
that was discussed by Wangda Zuo and Andy Mcneil in this paper:
