How To Parallelize This Nested Loop In Python That Calls Abaqus

I have the nested loops below. How can i parallelize the outside loop so i can distribute the outside loop into 4 simultaneous runs and wait for all 4 runs to complete before movin

Solution 1:

Use concurrent.futures module if multiprocessing is what you want.

from concurrent.futures import ProcessPoolExecutor

defeach(r):
    for k inrange( r*nAnalysis/4, (r+1)*nAnalysis/4 ):
        writeABQfile(ppos,props,totalTime[k],recInt[k],inpFiles[k],i,lineNum[k],aPath[k])
        delFile(aPath[k]+"/"+inpFiles[k]+".lck")
        runABQfile(inpFiles[k],aPath[k])

with ProcessPoolExecutor(max_workers=4) as executor:
    output = executor.map(each, range(4)) # returns an iterable

If you just want to "do" stuff rather than "produce", check out as_completed function from the same module. There are direct examples in the doc.
