I've not personally tested this, but it very much appears that just like x86, you can use a 64-bit ARM kernel that has 32-bit support enabled to run a 32-bit userspace, likely compatible with docker, or even just in a chroot. Then with 120 cores, "make -j 120"
I had been maintaining a fork of the U of KY BDR with SBCs and Arm devices in mind, might need to revive it for RISC-V.
