The toolkit also provides the capability to monitor TCP/IP for z/VM, as well as to process Linux performance data.
Application Enablement
•C/C++ for z/VM Compiler (5654-A22)
CMS will host the new C/C++ for z/VM compiler (5654- A22). This environment allows C/C++ programs to be compiled and executed on CMS and creates portability between z/VM and z/OS C/C++ programs. C/C++ source fi les can be read from a CMS minidisk, the SFS, or the Byte File System (BFS) and output can be written to any of these fi le systems. C/C++ will only execute on z/VM V4.4 and can only be licensed to operate on stan- dard processor engines. In order to support the C/C++ for z/VM compiler, the C/C++, the Language Environ- ment has been updated to the level shipped with z/OS V1.4 and is integrated into the base of z/VM V4.4.

Networking with z/VM
TCP/IP for z/VM delivers expanded Internet/intranet access, improved on demand business performance and extended function. Performance of the TCP/IP stack was enhanced by redesigning algorithms to reduce path lengths, recoding procedures to optimize
TCP/IP is designed to support the z/Architecture HiperSockets function for
The z890 and z990 servers include an important perfor- mance enhancement that virtualizes adapter interruptions and can be used with V=V guests (pageable guests) on z/VM V4.4. With the enhancement of the TCP/IP stack in z/VM V4.4 to use adapter interruptions for
z/VM V4.4 exploits the Virtual Local Area Network (VLAN) technology. VLANs ease the administration of logical groups of users so that they can communicate as if they were on the same physical LAN. VLANs help increase traffi c fl ow and may help reduce overhead to allow the organization of networks by traffi c patterns rather than by physical location. To support VLAN, z/VM V4.4 provides:
•Enhancements to TCP/IP for z/VM to enable member- ship in a VLAN for QDIO and HiperSockets adapters
•Enhancements to z/VM
•Management and control of VLAN topology by the z/VM virtual switch
