The main difference between GPOS and RTOS is that the RTOS should be
deterministic. That is, the time consumed by the operating system to execute
it's service is fixed where as in GPOS it's variable.

GPOS

i. Non deterministic

ii. Time insensitive

iii. Can use virtual memory concept

RTOS

i. Deterministic

ii. Time sensitive

iii. Can't use virtual memory
