Theory tasks compile and run pythia8.exe and rivetvm.exe
I ran elfx86exts on them.(A rust program that disassembles a binary and print out which instruction set extensions it uses.)
They use SSE2 at most.
elfx86exts 3/cernvm/shared/pythia8/pythia8.exe
File format and CPU architecture: Elf, X86_64
MODE64 (call)
SSE2 (cvtsd2ss)
SSE1 (movss)
CMOV (cmovns)
Instruction set extensions used: CMOV, MODE64, SSE1, SSE2
CPU Generation: Intel Core

elfx86exts 3/cernvm/shared/rivetvm/rivetvm.exe
File format and CPU architecture: Elf, X86_64
MODE64 (call)
SSE2 (cvttsd2si)
Instruction set extensions used: MODE64, SSE2
CPU Generation: Intel Core
I still haven't figured out how to pass CFLAGS=" -march=native " into container environment even with app_info.xml

This should allow theory to run:
Add systemd.legacy_systemd_cgroup_controller=yes and systemd.unified_cgroup_hierarchy=false to GRUB_CMDLINE_LINUX in /etc/default/grub
Then run update-grub and restart

You should also add instructions for disabling cgroups v2 so Theory tasks don't crash.

Someone needs to create a step by step guide for installing and configuring cvmfs, boinc and apptainer, without building from source.

Append CVMFS_QUOTA_LIMIT=10000 to /etc/cvmfs/default.local to make local cache 10000 mb. You can even set it to 100000.

Try to append systemd.unified_cgroup_hierarchy=false systemd.legacy_systemd_cgroup_controller=false vsyscall=emulate to GRUB_CMDLINE_LINUX_DEFAULT at /etc/default/grub and then run "sudo update-grub".

One good thing is that we won't have atlas unsent tasks any more.
Server will now be able to keep up and generate new tasks.
