(Updated June 24, 2015, 11:56 p.m.) Review request for Default. Repository: gem5 Description ------- Multi gem5 is an extension to gem5 to enable parallel simulation of a distributed system (e.g. simulation of a pool of machines connected by Ethernet links). A multi gem5 run consists of seperate gem5 processes running in parallel (potentially on different hosts/slots on a cluster). Each gem5 process executes the simulation of a component of the simulated distributed system (e.g. a multi-core board with an Ethernet NIC). The patch implements the "distributed" Ethernet link device (dev/src/multi_etherlink.[hh.cc]). This device will send/receive (simulated) Ethernet packets to/from peer gem5 processes. The interface to talk to the peer gem5 processes is defined in dev/src/multi_iface.hh and in tcp_iface.hh. There is also a central message server process (util/multi/tcp_server.[hh,cc]) which acts like an Ethernet switch and transfers messages among the gem5 peers. A multi gem5 simulations can be kicked off by the util/multi/gem5-multi.sh wrapper script. Checkpoint support will follow in a subsequent patch.
