ibacm - InfiniBand Communication Manager Assistant
- Description:
The ib_acm daemon helps reduce the load of managing path record lookups on
large InfiniBand fabrics by providing a user space implementation of what
is functionally similar to an ARP cache. The use of ib_acm, when properly
configured, can reduce the SA packet load of a large IB cluster from O(n^2)
to O(n). The ib_acm daemon is started and normally runs in the background,
user applications need not know about this daemon as long as their app
uses librdmacm to handle connection bring up/tear down. The librdmacm
library knows how to talk directly to the ib_acm daemon to retrieve data.
