I had been using an Raspberry Pi 4 with 4 gigs of Ram for 3 or 4 months and it was working really great. One thing I noticed about it, which was different from every other Pi i've used was it seemed like it was doing multi-threading on it's own.

I would put " htop" in the terminal and I could see the different processors workload changing, increasing, decreasing, etc.

I upgraded to a Pi 4 with 8 gigs of Ram. One of the Pure Data pieces I was able to play pretty easily on the other pi with 4 gigs I am having a hard time doing on the Pi that is 8 gigs of Ram. I ran htop in the terminal and I was surprised that it's not multi threading. I had one processor doing almost all the work, and I am getting Stack Overflow in the Pd terminal, and the audio will sound crappy and just cut out sometimes.

My question is should I increase the buffer size? Will this make it less likely to have a stack overflow?

Also, is there some setting I need to do to get the multi threading that I don't know about?

Thank you for the help in advance.

By the way, I accidentally corrupted my Pi 4, 4 gigs of ram disc image so I can't go back and look at it. I know, stupid mistake.

I think something is just wrong with this particular patch. I opened a few other patches and they worked ok and did do multi threading.

This one particular patch doesn't and it also has stack overflow problems. I have a feeling it's because it has stuff from older librairies when I made it and it's using newer libraries now, so things are a little messed up.

Anyway, I'm gonna say this one is solved and just trash this patch , or update it.

thanks, Nick
