Proud Friend of the Z Community - Computer Measurement Group

Proud Friend of the Z Community

Founded as a Mainframe User Group in 1975 when a group of some 200 computer professionals rallied to the cause of vendor-independent evaluation and improvement of computer performance. Armed with trusty metrics, focused minds, and unparalleled dedication to CPE, they incorporated as a non-profit organization in 1976 and ever since, CMG has served as a resource and gathering place for unbiased, vendor-neutral discussion about performance, capacity, and all things DX and enterprise technology.
