Run applications on Popcorn Linux

Run the pingpong application

The pingpong application is located at popcorn-compiler/docker/pingpong. You need to follow this link to build it, and then send both of the generated popcorn binaries (i.e., pingpong_x86-64, pingpong_aarch64) to the popcorn guest OSes. Make sure the popcorn binaries are at the same location on each guest OS.

❯ scp pingpong_x86-64 pingpong_aarch64 root@10.2.0.2:
❯ scp pingpong_x86-64 pingpong_aarch64 root@10.2.1.2:

Next, make a copy of the binary and rename the binaries on each VM. You need to have the following three binaries on each VM:

root@x86:~# cp pingpong_x86-64 pingpong
root@x86:~# ls -lth
total 56M
-rwxr-xr-x 1 root root 6.5M Feb 28 18:43 pingpong
-rwxr-xr-x 1 root root 5.5M Feb 28 18:38 pingpong_aarch64
-rwxr-xr-x 1 root root 6.5M Feb 28 18:38 pingpong_x86-64

root@arm:~# cp pingpong_aarch64 pingpong
root@arm:~# ls -lth
total 53M
-rwxr-xr-x 1 root root 5.5M Feb 28 18:44 pingpong
-rwxr-xr-x 1 root root 5.5M Feb 28 18:38 pingpong_aarch64
-rwxr-xr-x 1 root root 6.5M Feb 28 18:38 pingpong_x86-64

Finally, run pingpong from x86 side, and you should see the kernel of code migration:

root@x86:~# ./pingpong                                                              │root@arm:~# cp pingpong_aarch64 pingpong
