p4sock
Use optimized communication via (Gigabit) Ethernet.
The script handling this hardware type ps_p4sock is also located in the config subdirectory. It
understands the following two environment variables:
PS_TCP
If set to an address range, e.g. 192.168.10.0-192.168.10.128, the TCP bypass feature of the
p4sock protocol is enabled for the given address range.
openib
Use the OpenFabrics verbs layer for communication over InfiniBand.
No script is currently implemented for this communication protocol, therefore no environment
variables are recognized.
mvapi
Use the Mellanox verbs layer for communication over InfiniBand.
No script is currently implemented for this communication protocol, therefore no environment
variables are recognized.
gm
Use communication over GM (Myrinet).
The script ps_gm will load the Myrinet gm driver.
PS_IPENABLED
If set to 1, the IP device myri0 is enabled after loading.
elan
Use communication over QsNet (libelan).
No script is currently implemented for this communication protocol, therefore no environment
variables are recognized.
This communication layer is currently not supported by the ParaStation communication library,
therefore only programs linked with the QsNet MPI will work.
ipath
Use communication over InfiniPath.
No script is currently implemented for this communication protocol, therefore no environment
variables are recognized.
This communication layer is currently not supported by the ParaStation communication library,
therefore only programs linked with the InfiniPath MPI will work.
dapl
Use communication over a generic DAPL layer.
No script is currently implemented for this communication protocol, therefore no environment
variables are recognized.
