mpiexec wont run program couzed by schroot arm64 userland.

[Nivey]

I'm running a bunch of raspberry pi 4's and when i login to a single node i need to run schroot -c pi64 to get to the 64 bit environment.
In this environment my program is installed but when i want to run the mpiexec command to run it on all nodes the master node can not run the program on the other nodes since it won't be in the 64 environment. is there a way to fix this?

thanks in advance
