In with a lot of attention to virtual desktop friends to do communication, everyone will ask me: why PCoIP have hardware card scheme? You know, before the advent of the PCoIP, no one in the industry to provide hardware card program Oh!
We first look at the virtual Desktop Connection diagram, the server's virtual desktop to complete the screen information compression, coding, the client performs decompression, decoding.
Transmission in the network is only the change of the screen information (in fact, the transmission is only pixel information, such as Rgb,cmyk color, not the legendary bitmap way), the mouse keyboard instructions (coordinates, action information). Now the display resolution is getting bigger and larger, if the virtual desktop side does not do any compression, the encoding is passed directly to the client, which is obviously unwise, so at present almost all the remote Desktop
Protocols Use this approach to complete user actions.
Let's look at the location of the PCOIP hardware card: Considering the cost factors, in general, only users with very high graphics performance requirements (such as 3D design, animation design users) will use the PCOIP hardware card scheme.
One of the original Jongxiaori to you.
When running a large 3D, animated program, CPU usage is generally higher, and even instantaneous to 100%, and the front of the screen interface to the compression, coding work must be CPU to complete, obviously now the CPU has no ability to complete this operation, so the user interface will be stagnant (play CS etc games will say , this is called "card")
PCoIP Hostcard card is to solve this problem, the CPU on the host is only responsible for running the application, and the screen is transmitted by the PCOIP host card to complete. (Old saying: their own duties)

PCoIP 0 Clients
Similarly, if the client's CPU is now busy, the server on the screen changes obviously can not let users see the first time, therefore, the PCOIP protocol design will naturally appear the dedicated 0 clients.
PCoIP Server Offload Card
In the recently released View 5.0 products from VMware, Teradici also released a server-side host card designed for view, which you can plug into the vsphere server to reduce server CPU load and improve server integration. Reduce the cost per virtual desktop.
