Hi Guru, To speed things up, here are some options:
1. Use atomic to get the point of interest, then take a checkpoint. Is this what you are doing? 2. For the above, run with --fast-mem since you’re not warming any caches anyways. 3. If possible, use the KvmArmCPU instead of (1). This should give you a significant boost. If the amount of work is constant, than running with dual should not slow things down. If you’re seeing a slow down, then perhaps something odd is going on in the simulation (interrupts getting lost etc). Have you tried with the latest trunk?
