Re: model 720 comparison

Steve,

The new 720 model 2062 has two processors, so it should be able to run two
copies of your CL program in about the same length of time as the old one
runs one.

Unfortunately, both processors in the new 720 cannot be used by the same
job, unless the job has multiple threads.

So, the new 720 is twice as good at multitasking.

And it can do LPARs.
