The program does not execute. #6

Closed hckuo2 closed 6 years ago

hckuo2 commented 6 years ago

I followed the instructions and run with the recommended parameters. The program seems to execute and exit normally. But the result shows this. The compute time is always zero. Is this normal?

Hi,

Most (if not all) of the Splash benchmarks count the time in seconds. What seems to be happening here is that the benchmark finishes in less than a second, hence why the execution time is 0. This, in turn, happens because the input is small. Some benchmarks have bigger inputs that can last more than one seconds, but not all of them. Since Splash-3 is used a lot with simulators, the recommended inputs are aimed at simulation, not native execution, and are not generally very big.

Does this solve your problem?

Regards,

Chris
