The CPU that is operating, as reported by Windows.


Reports the number of GPU devices installed in the system, if GPGPU capable, as reported by NVIDIA drivers, using the name CUDA, the name of the NVIDIA GPGPU programming library which the card must support.  When only one GPGPU capable card is installed in the system, if the card reports the name of the card that will be reported as well as the CUDA level the card supports.  If no GPGPU-capable device has been installed in the system, will report Graphics only for the GPU.  The illustration above shows a system with two GPU cards installed that are GPGPU capable and are thus reported as CUDA (2 devices).

Buy Manifold 9

Appears for Manifold Viewer and does not appear for Manifold Release 9.   Launches the Manifold Online Store entry page in the default browser.


Close the dialog.




The illustration above shows a typical display for Manifold Viewer.    There is no serial number since Viewer is a free product that does not use serial numbers.   The dialog shows an installation on a machine that has an AMD processor and which has only one GPGPU capable card, reported as CUDA (GeForce GTX 1060 6GB (6.1))  - it is a GTX 1060 with 6GB of on-card memory and it supports CUDA version 6.1.  


Windows 10 on the above machine has been updated to the 1809 update.  The "Buy Manifold 9" button is the only place in Viewer where there is any mention of a commercial product.



ico_nb_arrow_blue.png  Manifold does not automatically check for updates.   After installation, at any time check for any newer versions available by choosing Help - About.   When the About dialog is launched, Manifold will reach out through Internet to check for a new version.
