Another brain wave I'm afraid. Is there any means to (currently or in future) have smedge engines execute a simple commandline when they 'gracefully' close down?

We're able to have our cpu Table and status changes on their work progress as you'd expect but it'd be interesting to see if the workstations could send a signal to say they're not on the farm 'outside' of the smedge gui.
Cheers

One way to accomplish this is to wrap the SmedgeEngine executable in a batch file. Then you could do whatever you wanted before the Engine process starts and after it finishes, using the batch file.

The event system in Smedge will be expanding in Smedge 2011, and may allow ways to set this up inside of Smedge itself. We'll see how that shapes up as we start implementing it.

Thanks

Hi Robin,

Yup, that's the short term approach I'll be testing today. Possible some process misbehaving may crash it, but let me see if that'll work for the time being.

Cheers

I would suggest in your batch file that you check the result of the SmedgeEngine process. If the process terminates normally, the error level should be 0. That way, your batch file can detect if the Engine shutdown properly or in a not so good way.

Hi Robin,

I've made some great in-roads in python process launching and such but the event where someone 'shuts down' smedge and it's associated launch wrapper the parent process and the smedge engine process both die with immediate effect. The last thing being effectively actioned is the 'shutdown' signal from smedgeengine.exe being sent to the master.

Looks like I'll have to create a pulse system of some sort.

Update: I've thrown every python subprocess variable and dos event at it with no joy. I'm going to have to create a polling app which will query the engine list from our master to keep the node status in the MySQL tables accurate.

Cheers

Jamie

Hi Robin,

I've elected to execute and parse the output from the 'Engine.exe List' command. Thing is the master, specially when it's busy will stop responding to this query if I run it over a long period of time.

I suspect, as mentioned in the other thread, it's the master messaging system failing internally. I'm moving onto 2010 to see how that shapes up but I'm not able to throw over all our cpus onto it till the next release. If I hit any problems I'll mail you directly.

Cheers

Jamie

Hi Jamie,

Smedge 2010 should significantly reduce messenger system problems compared to earlier Smedge 3 versions. If you have trouble with it, please let me know. There will be an update coming out early next month with some more bug fixes as well. Contact me directly if you have any questions about it.

Thanks
