Tuning for threads, CPUs and cores

[xrd]

I'm trying to tune my transcription output.

I've got a CPU that indicates it has 12 processors. Can I use -p 12 with this? Or, is this switch for physical individual processors? Should i use a certain number of threads for each processor, depending on the power of the processor? For example, if I specify -t 4 will that use 4 threads per processor, or will it use a total of 4 threads across the processors I specify?

I searched for discussion threads on "tuning" here on GitHub but didn't see any. If i missed them, please send it on.

This is what cpuinfo shows:

The -p argument of main is not related to the CPU processor.
These are "Whisper" processors. It's a strategy that we explored to split the input audio into -p chunks and process the chunks in parallel. Sometimes it can speed-up the process, but the transcription result at the splits will likely be worse due to partial words and losing context.

A rule of thumb is that -p * -t should be less or equal to the number of CPU cores that you have.
