Intel MPI
compat-dapl-devel-static-1.2.12-1.x86_64.rpm
compat-dapl-utils-1.2.12-1.x86_64.rpm
Using DAPL 2.0.
$ rpm -qa | grep dapl
dapl-devel-static-2.0.19-1
compat-dapl-1.2.14-1
dapl-2.0.19-1
dapl-debuginfo-2.0.19-1
compat-dapl-devel-static-1.2.14-1
dapl-utils-2.0.19-1
compat-dapl-devel-1.2.14-1
dapl-devel-2.0.19-1
2. Verify that there is a /etc/dat.conf file. It should be installed by the
dapl- RPM. The file dat.conf contains a list of interface adapters
supported by uDAPL service providers. In particular, it must contain
mapping entries for OpenIB-cma for dapl 1.2.x and ofa-v2-ib for
dapl 2.0.x, in a form similar to this (each on one line):
OpenIB-cma u1.2 nonthreadsafe default libdaplcma.so.1 dapl.1.2
"ib0 0" ""
and
ofa-v2-ib0 u2.0 nonthreadsafe default libdaplofa.so.2 dapl.2.0
"ib0 0" ""
3. On every node, type the following command (as a root user):
# modprobe rdma_ucm
To ensure that the module is loaded when the driver is loaded, add
RDMA_UCM_LOAD=yes to the /etc/infiniband/openib.conf file.
(Note that rdma_cm is also used, but it is loaded automatically.)
4. Bring up an IPoIB interface on every node, for example, ib0. See the
instructions for configuring IPoIB for more details.
Intel MPI has different bin directories for 32-bit (bin) and 64-bit (bin64); 64-bit is
the most commonly used.
To launch MPI jobs, the Intel installation directory must be included in PATH and
LD_LIBRARY_PATH.
When using sh for launching MPI jobs, run the following command:
$ source /bin64/mpivars.sh
