Sure, on Pine64 and on any other ARMv8 board it's important compile the programs since some algorithms are 20 times slower when not being compiled for ARMv8:
Code:export CXXFLAGS="-O3 -march=armv8-a -mtune=cortex-a53"
export CFLAGS="-O3 -march=armv8-a -mtune=cortex-a53"
Then the board gets as hot as with optimised settings but is still slow as hell. Have a look at the commonly used sysbench: http://forum.odroid.com/viewtopic.php?f=136&t=19158
Hi Andrew,
are you talking about compilation of BOINC app?
I am asking because I wonder if this app is doing any calculations by itself?
I have a feeling that it downloads ready apps and spawns separate processes for them.
Here are some of "ps aux" from my PC machines:
