Something I've noticed.

For a while now, I have not been getting multiple messages per second when decoding on the Mac mini. I used to, but it had stopped.

I know this as I have a program to take the decodes binary files and upload them to a PostgreSQL DB. While importing, it prints out stats. At the end, it shows some totals.

For the win10 box:
Defined Timestamps: 658587   ** Number of timestamps as stated within the .dec file
Total Timestamps: 658587       ** Number of timestamps that the program counted (it better equal the previous one)
Unique Timestamps: 546327    ** Number of unique timestamps (taking into account multiple per second. There can be a max of 2 full messages and a part of a third. Unknown how ADGPS assigns messages to a timestamp).

Unfortunately, I do not have the stats from the Mac mini for this day, as I thought I saved the decodes before starting, but... I did not. I closed ADGPS before realizing this and all that I have is the printed list above.

But I do remember that the three numbers were equal on previous days. Thinking that my program had a bug for not counting right, when run through with the Win10 decodes, it clearly did have multiple per second. There were none > 3 per second as that's a hard coded check and will abort, since it is impossible at 200 bps to have 4 messages.


Chris, can you make a version (for Mac & winders), where we can set the number of decoding threads, from 1 to max? Also, would like an option to pick a set of frequencies to decode. Mainly so I can see if limiting the number of threads makes it more deterministic and also on received signal strength. Not sure how easy this would be.

Right now, the software has a separate thread for each demodulator (frequency and baud rate). I'll have to check and see how difficult it would be to make multiple demodulators run on the same thread. 

One fairly easy test (at least on the Mac) would be to just change the compiler optimization from maximum to minimum. It would run slower, possibly much slower, but you could see if there's a difference in the decodes.  Honestly I have no idea what the optimizations are set to for Windows builds. They just kinda happen

I'd like to see how much slower it would run if it was at max (160? threads) or limited to 1 thread per core. How much context switching is slowing it down?

Yeah, I have no idea about Windows. It just happens to be an available speedy machine.

If you ever make a different one for R Pi, I have one running & ready to go at a moment's notice. And if you can get it going on Raspbian, it shouldn't(??) be too hard to get it going on Ubuntu on x64, and I have one of them that's fairly bored.

Doubt I could write a Perl script to do it. Maybe John Poet can make one in PHP, he seems to be a fan.
