Mon 11 May 2020 01:33:45 PM UTC, original submission:  

for loop
    parcellfun_set_nproc(0) ;
    Params = complex code
    [result1, result2] = parcellfun(nproc-4, fun, Params, "UniformOutput", false) ;
endfor

time inside parcellfun ranges from 1 to 5 seconds.
parcellfun_set_nproc returns with the following 8 times with each loop:
    could not terminate child process

After about 8 hours of execution time, I ge the following message:
    could not close child pipe ends in parent
    couldn't create process

Which is a bit frustrating, as I expected my job to run for about 30 hours.
