- 1 minute read
Currently, about 20 instances of SCP (CP270) can execute on a single SCP computer platform; however, performance is application specific. Performance is affected by the number/size/type of blocks in each CP, the number of OM lists, the number of OM sink points, etc.
Some statistics for the supported CP hardware types are shown below.
