Lion: What is Talagent?

Hello! I use gfxCardStatus to tell me and switch which graphics card is running on my i7 MBP, and i noticed that in lion, fairly often, under dependencies, it lists something called talagent. It is causing the discrete graphics to be triggered on. Apparently it is located in System/Library/CoreServices/

Anybody know what this is or why it would be causing the GPU to come online?

Yes, I did come across that as well. Doubt there is any link though.

One string within "talagent" is:
Quote:
"Used by the persistent state feature to encrypt window snapshots to ensure privacy."
So i think it has something to do with the new "Resume" feature.

Hmmm… Not sure. Used Activity Viewer to see what files it had open and it was directly talking to MDS (aka spotlight) Here is the file list… I opened the one that was in the mds directory (the .db) and it had a bunch of references to security. Not sure if this os common but for what it is worth, the files:

@Demetri:
Your list contains files opened by the kernel and files opened by the app/agent/daemon. It does not mean that talagent has opened these files.

Wow, any developer should know to use the unix manual...

"man talagent" gives this...
Code:
NAME
     talagent -- talagent is a helper agent for the Transparent App Lifecycle
     feature.

SYNOPSIS
     talagent --dump bundle_id_fragment

DESCRIPTION
     The talagent tool provides services related to the Transparent App Life-
     cycle feature.

     talagent may also be run manually to output information about the persis-
     tent state of an application.

     The options are as follows:

     -dump bundle_id_fragment
         Outputs the persistent state of an application whose bundle ID con-
         tains the given fragment, case insensitive ("textedit" for example).
         You may also pass a path directly to the app's persistent state
         directory, usually in ~/Library/Saved Application State.

     -launch bundle_id
         Launches an application stopped, as they are launched when logging
         in, and does not start the app until you press return. Any bitmaps
         for the application are decoded and shown in proxy windows, and the
         app may adopt those windows when it is started. This is a way to test
         the application's behavior when launched from loginwindow, without
         actually needing to log in.

     -memory_pressure
         Simulates memory pressure, which may cause apps that support auto-
         matic termination to exit. This does not actually allocate any mem-
         ory.

HISTORY
     First appeared in Mac OS X 10.7

No one in this thread claimed to be a 'developer'. You also don't need to be a 'developer' to download a torrent.

This looks interesting I wonder if it would be a worth while utility to have that looks for the launch of your big productive apps and fires this off just to clean things up a bit.

Maybe fire it off at regular intervals just to make stuff isn't hanging rounds unless it needs to be.
