I am running a code in Ampl I want to make sure my code is running still ,( I can not see it from software). in activity monitor the %cpu for this software is 99.6 .

Is this mean the code is running?

isn't it too much for cpu? 99.6?

The CPU% value shows how much CPU load a process generates. A value of 100% means that the process uses one CPU core fully. As all modern Macs use multi-core CPUs you can even see processes with more than 100% CPU load sometimes (requires the process to be written in a way to make use of several cores at once of course).

So in your case the process is running happily. What Activity Monitor doesn't show you though is whether the process just runs in an endless loop or whether it actually processes its data as you expect.
