Make SiMon behaving as a job submission system, so that if the users have a few jobs, e.g., jobs/python job_1.py, jobs/python job_2.py, dir/my_prog.exe, then the jobs submitted with

simon -c "jobs/python job_1.py"
simon -c "jobs/python job_2.py"
simon -c "dir/my_prog.exe"

Without the need of using ic_generator to generate directories and config files whatsoever.

Set up nbody code on virtual env is not easy, so leave travis-ci for future. Currently write a test code for running simulation on local machine, will be done after #23

• Explicitly display "ID" keyword
• Change the confusing "Unknown" message

@maxwelltsai Any idea?

• Create binary logs, bookkeeping all activities with accurate time stamps
• Periodically generate PDF files for a nicer (high-resolution overview) of the simulation status.

Replace the absolute dir in sim_start_command and sim_restart_command with relative dir, as in icutil_pseudo_simulation.py

sim_start_command = \
    'python -u /Users/maxwell/PycharmProjects/SiMon/pseudo_simulation.py -a %f -o %f -t %f 2>error.txt'
sim_restart_command = \
    'python -u /Users/maxwell/PycharmProjects/SiMon/pseudo_simulation.py -a %f -o %f -t %f 2>error.txt'

Optimize interactive mode dashboard

Hi,
I am having trouble starting simon on two systems, one with a fresh install of python3 (on a docker image) but on my local computer as well.

I installed simon with :
python3 -m pip install astrosimon

which currently install astrosimon-0.8.5

the simon command works but the daemon seems to fail:

Can you reproduce this error on a fresh install?

I tried installing directly from git but there I got a different error, I could open another issue for that.

Any ideas?

as below:

0|---'root' 1969-12-31 19:00:00 1969-12-31 19:00:00

DONE T=[0-80] CID=-1 level=1
T=[0-0] CID=3 level=0

the 3| should not be shown on root here

I guess there are some trigger between start and stop, which requires these two actions to be done in sequence without interruption.

e.g. if users did python simon.py start, and at this time they update the simulation dir and did python simon.py start again, the simulations are actually not started, there is a need to do python simon.py stop first and then start again.

@maxwelltsai Any idea?

@maxwelltsai There is a 'usage' msg pop out (as below) when using simon-start command line, while the command line is correct and Simon daemon is already running. Do you know where in the code does this happen? I didn't found print_help function got called in this case. Thanks!

➜ SiMon git:(logic_conflict_start_stop) ✗ simon-start
usage: simon-start start|stop|restart

Some instances reaches the termination time, but SiMon doesn't mark the simulation as DONE.

I used pip3 install astrosimon and get Successfully uninstalled astrosimon-0.2.0, which is too old and only compatible with Python 2. Then I successfully installed version 0.8.5 with pip install https://github.com/maxwelltsai/SiMon/archive/master.zip.

Just a reminder that SiMon in pip is not updated for long.

@maxwelltsai There are some confusion about variable names such as

In simon.py

• self.sim_inst_dict = dict() -> sim_insts or sim_inst_pool
• self.sim_inst_parent_dict = dict() -> self.sim_inst_parents

Nothing happens when the user attempts to kill a process.

• set simulation code/work space dir
• which sim_tree is using (relevant code also needs to be modified in simon.py )

We could merge two mode entries into one script, and let users choose from terminal which mode to run the code.

Extend SiMon's UI support to iPython notebook.

Maybe we should make a new simulation directory for users instead let users create folder under nbody6/run dir

We should enable sim_root_dir in icutil_pseudo_simulation.py to get dir from reading SiMon.conf, instead of let users to assign it? @maxwelltsai

As seen below, as the running time is changed, the status is not changed as still 'DONE'
@maxwelltsai is this normal?

@maxwelltsai Currently there is no output after starting daemon mode, although user could switch to interactive mode or check the log file to see if daemon is running, while it could be more 'direct' and convenient to put a brief info or even a progress bar.

The error is as below

So the thought it using
simon simulation_dir interactive/daemon to run the code after users pip install it

For example, if the user creates a "restart" directory manually, and this directory does not have a SiMon.conf file, the daemon will crash.

If the user launches SiMon in an empty directory, it will ask the user whether they would like to create a default SiMon.conf on this directory. After the creation of the default config file, it will ask the users whether they want to generate some test simulations.

This measure will hopefully significantly reduce the learning curve of SiMon for new users.
