Raspberry Pi 4 - Tips?

(moderation:
Just loaded BOINC on one of my RPI4's, it seems to be running fine, however I wont know for sure until the tasks start completing.
In the meantime, does anyone have any tips for number of tasks to run concurrently or any other setup I should be aware of?

I'm sure that Keith would know. He is our Guru when it comes to RPI4's.

Thanks GW, I'll wait and see if he throws something in here...
I decided to run 3 concurrent for now since my temp appears to be fine at 58c.
I forgot to change the checkpoint time and had to make a couple of other changes that resulted in a reboot so I lost a bit of work. Guess I'll have to wait even longer to see how these tasks do. 69% and counting....

I run a cluster of PI'4s, with my setup I've found that running all the cores with tasks will overall get more work done compared to say running with 3 cores (although when running with 3 cores a task will finish quicker, but not by that much, so 4 cores beat 3 cores)
Most (all but 1) of my pi's live in a flirc case (aluminium case), and also sit on a bit of aluminium as well, and as long as i keep the overclock to 1800MHz or less then no additional cooling is required, but I live in the UK and very rarely gets that hot.
The pi's that are overclocked to 1900 & 2000 MHz (early pi's run safely at 1900 & newer pi's run happily at 2000 24 hours a day). do need additional cooling to help keep temps less than 70deg C, I have a few fans running very slowly to help keep temps in check (but not needed if the office room temp is less than 20 deg). Note my original plan was not to use fans and only use passive cooling (that's why they are in ally cases), but the speed monster in me needed that extra few percentage in speed.

You need to run the BOINC

You need to run the BOINC benchmarks. I use all 4 cores on my Pi4's. I would suggest increasing the check-point interval to reduce wear on the SD card.
Seeing as you have a Pi4 8GB I would suggest you run the optimized app. Its quicker than the project provided app. It uses a bit more memory but given you have 8GB available...

I'm running it on a SSD right now, but I will probably convert it back to SD if I'm going to continue using this with BOINC.
Thanks for the tips guys!

SSD is better than an SD card. SSD's are faster and have wear leveling that the SD cards lack, well the SD cards claim to have rudimentary wear-leveling.

Do you use 1 SSD drive for each Pi or 1 SSD for several Pi's? If the later do you do the 'server' thing that feeds Boinc tasks to each Pi and then back again to return them?
You helped me get my own Pi's running, they are in a box right now but I do hope to get them back on-line at some point, they are still using an SD card for each Pi.

Thought about making one of mine a network boot server as well, but doubt I'll have time to play with it....
