An assessment of the MODSIM/TWOS parallel simulation environment

The authors assert that the major flaw with the ModSim/TWOS (Time Warp Operating System) system as it currently exists is that there is no compiler support for mapping a ModSim application into an efficient C/TWOS application. Moreover, the ModSim language as currently defined does not provide explicit hooks into the TWOS and hence the developer is unable to tailor a ModSim application in the same fashion that a C application can be tailored. Without sufficient compiler support, there is a mismatch between ModSim's object-oriented, process-based execution model and the Time Warp execution model. The authors present their assessment of ModSim/TWOS and also discuss both components in isolation.<
