Run FEASST as server with Python client
In this example, run feasst in server mode and use a Python client to send text interface commands.
[1]:
import multiprocessing
import subprocess
import time
import socket
PORT = 54321
BUFFER_SIZE = 1000
def server():
subprocess.call('echo "Server port '+str(PORT)+' buffer_size '+str(BUFFER_SIZE)+'" | ../../../build/bin/fst', shell=True, executable='/bin/bash')
def client():
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect(("localhost", PORT))
for line in ['MonteCarlo',
'Configuration cubic_side_length 8 particle_type0 /feasst/particle/lj.fstprt',
'Potential Model LennardJones',
'ThermoParams beta 1 chemical_potential0 1',
'Metropolis',
'TrialTranslate',
'TrialAdd particle_type 0',
'Run until_num_particles 20',
'Remove name TrialAdd',
'Log output_file lj.csv',
'Run num_trials 10']:
sock.send(bytes(line, 'utf-8'))
message = sock.recv(BUFFER_SIZE)
#print(str(message))
if __name__ == '__main__':
proc1 = multiprocessing.Process(target=server, args=())
proc2 = multiprocessing.Process(target=client, args=())
proc1.start()
time.sleep(1)
proc2.start()
proc1.join()
proc2.join()
