Fujitsu Coherent Memory Interface (CMI) driver is a multi-threaded and loadable device driver.
Fujitsu CMI driver provides functions to control inter-node shared memory enabled by Fujitsu Global Coherent Shared Memory (GCSM) Extension. Two or more physical nodes can share data through inter-node shared memory, which provides fast inter-node communication.
The following functions are supported by Fujitsu CMI driver.
Allocate and deallocate shared memory
Map and unmap shared memory to user processes
Export shared memory to remote nodes, and import shared memory from home nodes
Generate error events when data access error occurs on shared memory
Generate error events when home or remote nodes are disconnected from inter-node shared memory network
Special character device to control CMI driver
Special character device to obtain CMI status information
64-bit device driver (SPARC)
