servst

Gitlab

1. Description

servst is primarily a collection of tools designed to inspect the utilization status of each server. Then I add support for MD tasks, to show them or kill them conveniently and thoroughly.

• gpust and cpust provide status for servers
• gpurf and cpurf refresh status information for all or specific servers
• lsmd and lsmds fetch the latest progress of MD tasks for servers
• killmd kill target MD tasks

2. Installation

There is no need for installation. The commands are available as global aliases.

HOWEVER, password-free configuration is recommended for gpurf, cpurf and lsmds

3. Usage

3.1 For gpust and cpust:

These commands can be used on any server to get GPU or CPU status of any server. If prompted, enter the password of rainbow.

3.2 For gpurf and cpurf:

1. gpurf updates the status of all servers. Without password-free configuration, you'll need to enter the password for 11 times... So it's highly likely that you will not use this one.

2. gpurf yellow updates the status of merely the wanted server yellow. You must either have password-free access or provide the password of yellow then rainbow when prompted. The statuses of the other servers will remain as previously displayed. The column Last Updated indicates updating time of each server.

3.3 For lsmd and lsmds

1. lsmd will get MD tasks' status in the current server. lsmds will get the statuses for several servers.

2. lsmds purple will fetch the information of the wanted server purple.

3.4 For killmd

Guide can be called by typing killmd -h.

usage: killmd.py [-h] [-a] [-p PID] [-g GPU]

Kill series of md tasks instantly.

options:
  -h, --help         show this help message and exit
  -a, --all          Kill all md tasks
  -p PID, --pid PID  Process ID to kill
  -g GPU, --gpu GPU  GPU id

• killmd -a will kill all md tasks in the current server.
• killmd -p 12345 will kill the task with pid 12345, as well as related tasks
• killmd -g 0 will kill tasks runing on GPU 0
