the program takes 100+ lightweight processes

[shalijiang]

when I was trying to run many jobs on a server, it results in an error "fork: retry: Resource temporarily unavailable" when over 30 jobs are submitted. I googled about it, the reason seems to be the limit of max number of processes is exceeded (by default on that server is 4096). Then I checked the number of lightweight processes of the job "python main.py Hartmann3 EI 4 1", using the command "ps -o nlwp ", it turns out the process has 134 lightweight processes, so I can only run about 30 jobs. Is this because of some parameter setting?
(FYI: I tried to change the "max_num_threads" parameter in line 55 from 8 to 1, but didn't make a difference. I also tested a simple for loop python program, it's only 1 lightweight process)
