Udapl Throughput Test Performance - Cisco GEM318P User Manual

uDAPL Throughput Test Performance

The Throughput test measures RDMA WRITE throughput using uDAPL. To perform a uDAPL
Throughput test performance, perform the following steps:
Start the Throughput test on the server host. The syntax for the server is as follows:
Step 1
/usr/local/topspin/bin/thru_server.x device_name RDMA_size iterations batch_size
The following example shows how to start the Throughput test on the server host:
host1$ /usr/local/topspin/bin/thru_server.x ib0 262144 500 100
RDMA throughput server started on ib0

The server starts and then waits for the client to start.
Start the Throughput test on the client. The syntax for the client is as follows:
Step 2
/usr/local/topspin/bin/thru_client.x device_name server_IP_address RDMA_size
The following example shows how to start the Throughput test on the client:
host2$ /usr/local/topspin/bin/thru_client.x ib0 192.168.0.1 262144
Server Name: 192.168.0.1
Server Net Address: 192.168.0.1
