1) Message boards : Number crunching : Time for a 64-bit ARM application? Other platfforms? (Message 548)
Posted 22 days ago by Dirk Broer
I can vouch that the new 64-bit Linux/ARM 1.16 app is twice as fast as the 32-bit 1.15 app was on a 64-bit platform, what do I need to do to test the 64-bit Android app? Is signing up for the project on my Android 9 running Odroid-N2+ enough?

There are both 32-bit and 64-bit x86 applications for Apple OS and Linux/x86, but so far the ARM application is only 32-bit and only for Linux/ARM

My idea is that the project will served by a 64-bit Linux/Aarch64 application in the view of Apple's move to ARM and the rise of 64-bit SBCs (e.g. Raspberry Pi 4, Odroid-N2)

Other missing platforms are Android/ARM, both 32-bit and 64-bit, and PPC (for old Macs, either OSX or Linux, both 32-bit and 64-bit).

I do hope that the new server is -at least- the former top model Power Mac G5, "Cypher" with four PowerPC 970MP cores, and the full 16 GB of DDR2 RAM.
If you have chosen for a laptop again, make it the Apple M1 equipped MacBookPro 17.1 -also with 16 GB, but now DDR4.

Do you use an app_info.xml?
If so, change the suffix to .bak, save and reboot -so you are running without app_info.xml.
5) Message boards : Number crunching : Project pick as FB Sprint -- NEED MORE TASKS! (Message 500)

A limit of 10 WUs per system would be enough to supply my crunchers for this project, the Raspberry Pi 2's already stay below that standard.

A limit of ten WUs per user would hamper me, as I have ten systems on the project, all of them quad cores-though only the six Raspberry Pi's are running WEP-M+2 constantly.

What would happen if I win the lottery and buy a 64-core Threadripper and set it to run WEP-M+2? Guess I'd run into the limit then, but I am generally running 40+ projects on more capable machines, so it wouldn't bother me.

He has been given many suggestions now and in the past and has always ignored them.

Might be a reason of the suggestor.
You have more then 1000 WUs in progress and still want more?

I would suggest to reduce the number of WUs per user to 100 or 10.


I would suggest a limit of WUs per system, not per user. Some of us have so-called 'cruncher farms' -mine is with Raspberry Pi's. Pi 4's are quite productive. As there is no WEP-M+2 at the moment, I'm now crunching Asteroids with the PI's. The Pi 4's usually complete four WEP-M+2 WUs every 2.5 hour, that would be forty in 25 hours per Pi 4....Asteroids takes half a day -per WU- on the Pi 4, a day and a half on the Pi 3 and two days and a half on the Pi 2.

rpi 2, running at 700 mhz stock


700 MHz is stock speed for the ARM11 equipped Raspberry Pi 1!

There are two different models of the Raspberry Pi 2:

    1. The original Raspberry Pi 2 v1.1 with a BCM2836 SOC, featuring a 32-bit ARM Cortex-A7 @900 MHz (stock)
    2. The later Raspberry Pi 2 v1.2 with a BCM2837 SOC, featuring a 64-bit ARM Cortex-A53 @900 MHz (stock)



Basically the model 1.2 is the same as the original Raspberry Pi 3B, but without wifi, so it can easily be 'overclocked' to the same speed as the original 3B: 1200 MHz. Be sure to apply a heatsink though!

Looks like the stats export was broken on March 2:

The export of stats seems to be broken, on both BOINCstats and FreeDC my credit is stuck at 1,843,382.

Strange, just aborted WUs that ran for 17 hours and showed 0.00% progress..
