5.4.2 kDAPL Installation Verification
The kDAPL test scripts require that both the kdapl and kdapltest kernel modules are
loaded. With two nodes, hostA and hostB, hostA starts the server program first:
# cd <install_dir>/dapl-1.2/bin
# ./ksrv.sh
Dapltest: Service Point Ready - ccil0
hostB can now start the client program and specify hostA’s RDMA address as the address to
connect to:
# cd <install_dir>/dapl-1.2/bin
# ./kregress.sh 10.40.32.52
Server Name: 10.40.32.52
Server Net Address: 10.40.32.52

5.6 Ammasso DAPL Compatibility Settings
The following shell environment variables are provided to enable compatibility with other
DAPL provider libraries. A brief description of each is listed below.
5.6.1 CCAPI_ENABLE_LOCAL_READ
The IBTA Infiniband specification states that all memory regions have local read access
implicitly (vol 1, sec 10.6.3.1). This is not true for the IWARP RDMA Verbs 1.0
Specification, which states that the consumer must explicitly enable local read access on
memory regions. This can lead to application errors for DAPL applications currently running
