在Ubuntu伺服器上需要運作gpu計算任務,由于需要無人值守的在顯存空間滿足條件的時候運作程式,于是有了自動顯示顯存的程式及自動運作任務的程式:
自動顯示顯存:
import os
import re
import time
memory_need = 10800 # 需求顯存大小
sec = 10 # 每幾秒檢查一次顯示卡空餘
flag = False
while True:
#print(time.asctime(time.localtime(time.time())))
output = os.popen('gpustat')
text = output.read()
list = text.split('\n')
#res = re.compile(r'\d+')
for i, m in enumerate(list[1:-1]):
#memory = re.findall(res, m)
#m1 = int(memory[5])
#m2 = int(memory[4])
m1 = m.split('|')[2].split('/')[0].strip()
m2 = m.split('|')[2].split('/')[1].strip().split()[0]
m1 = int(m1)
m2 = int(m2)
print('顯示卡 %d 剩餘記憶體空間 %d (MB)'%(i, m2-m1))
break
import os
import time
cmds = ["python x.py",
"python y.py",
]
