matmult - baseline VM stress test
matmult multiplies two large matrices together and checks the result. Hopefully this will help detect bugs in the VM system.
The version for OS/161 has been gimmicked to be less efficient space-wise than normal matrix multiplication. This allows it to both take up an interesting amount of memory and run in a non-boring amount of time.
matmult uses the following system calls:
matmult should run correctly once the VM system assignment is complete.
