Done Threads

[Roedy]

I have 6 cpu cores, but very few utilities will use more than one of them at a time. I thought I might write some bat files that split up and ran in parallel for a while then rejoined. I might use it to zip different directories, validate HTML on different sets of files etc, anything heavily CPU eating.

I am not aware of any TCC tools for doing this. You need a way to launch a btm file to run independently, and and you need something that will wait until N precesses check in.

Take a look at the DETACH command, and the _DETACHPID variable.

I use these to run several batch files at once, writing results to files. Using _DETACHPID I can tell when the batch file has ended, and process the resulting files that were generated from my batch files.

While this is not going to use 6 cpu cores, nor is it actual threading, it accomplishes the same thing for my needs.

Doesn't "START /AFFINITY=n" work?

Or you can use my EVENTUTILS plugin.

Good stuff. Thanks.

There no notes on iinstalling. Do you just put the appropriate DLL in the takecommand directory? You don't have to do anything to configure tcc to go looking for it?

No, not in the TCMD installation directory, but its subdirectory named PLUGINS for automatic activation on TCC start. Alternately, anywhere else, and dynamically activate or deactivate with the appropriate options of the PLUGIN command, as documented by HELP -> PLUGIN.
