The larger the supermarket gets and the more complicated the items are to find (large models, complex calculation tasks), the more you benefit from the help of your friends. Ideally, they all require the same amount of time to fetch the items and come back to you in one block. That's the situation when parallel work will be most efficient. | The larger the supermarket gets and the more complicated the items are to find (large models, complex calculation tasks), the more you benefit from the help of your friends.

+ | ??? Can I run ENVI-met on any Supercomputer ? | ||
+ | Yes, if the Supercomputer runs under or supports WINDOWS. If the operating system is LINUX or other, you cannot run ENVI-met as there is no LINUX version so far. | ||

- | The default setting is to use all available CPU cores. | + | The default setting is to use all available CPU cores, that are assigned by the operating system. How many cores this will actually be in the end, will not only depend on your computer, but also on the amount of other applications running parallel to ENVI-met. Also, the amount of cores is assigned dynamically by WINDOWS and is also requested dynamically by ENVI-met depending on the specific simulation task. In other words: If ENVI-met is operating in a model section that is not parallel, it will not request more than one core. |
