There are so many ways to install python, that I will not attempt to tell how.

Examples

lufah . units
lufah /rg2 finish
lufah other.local/rg1 status
lufah /mygpu1 config cpus 0
lufah . config -h
lufah host1,host2,host3 units
lufah host1,host2,host3 info

Notes

If not given, the default command is 'units'.

In 8.3, /group config cpus <n> is not limited to unused cpus across groups.

Group names for fah 8.1 must:
  begin "/", have only letters, numbers, period, underscore, hyphen
Group names on 8.3 can have spaces and special chars.
Web Control 8.3 trims leading and trailing white space when creating groups.
Group "/" is taken to mean the default group, which is "".
For a group name actually starting with "/", use prefix "//".

An error may not be shown if the initial connection times out.
If group does not exist on 8.1, this script may hang until silent timeout.
Config priority does not seem to work. Cores are probably setting priority.
Commands start and stop are macOS-only.

Cannot get/set some configs:

Code: Select all

$ lufah . info
  Host: alma
Client: 8.4.2
    OS: linux 4.18
   CPU: 4 cores, amd64, "Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz"
$ lufah . config on-idle
null
$ lufah . config keep-awake
null
$ lufah . config cpus
null
$ lufah . config cpus 4
ERROR: cannot set "cpus" on group None

User, team, passkey, and cause work.

Code: Select all

$ lufah --version
0.4.3

[calxalot]

Some config items are only valid for groups on v8.3+

I think everything but user, team, passkey, cause

[calxalot]

Try

Code: Select all

lufah / config cpus 4

[calxalot]

I didn’t think it was wise to allow some keys to be set on all groups. Nor to allow some and not others.

[calxalot]

If you need to use lufah with v8.4, I can push another release that supports progress and eta. Only matters for the units command.

[Marcos FRM]

Thanks, using "/" works. It would be nice a hint about this in "lufah . config -h" output.

If you need to use lufah with v8.4, I can push another release that supports progress and eta.

No hurry.

[Marcos FRM]

Noob question: can I dump a WU?

[calxalot]

No, because the api requires the uuid of the unit. I was lazy and didn’t think making folks type the uuid was cool.

Suggestions are welcome.

[Marcos FRM]

Perhaps a "dump-all" command.

[calxalot]

Ok. Sounds dangerous. Maybe make it interactive or require a —force flag.

[Marcos FRM]

It would be helpful to have 'timeout' and 'deadline' information in the output of the 'units' command. Or only 'deadline', to know when the WU will be automatically dumped if not completed in time.

[calxalot]

Ok. It will be > 80 columns. I added Core type, which made it 79.
Maybe I should use python os.get_terminal_size()
