Step 2 Verify the IPoIB functionality by using the ifconfig command. Step 3 Enter the ping command from 192.168.0.1 to 192.168.0.2. The following example shows how to enter the ping command: IPoIB Performance Page Sample Startup Configuration File IPoIB High Availability Merging Physical Ports Unmerging Physical Ports Page SCSI RDMA Protocol Configuring SRP Configuring ITLs when Using Fibre Channel Gateway Configuring ITLs with Element Manager while No Global Policy Restrictions Apply Page Configuring ITLs with Element Manager while Global Policy Restrictions Apply Page Configuring SRP Host Verifying SRP Verifying SRP Functionality Verifying with Element Manager Sockets Direct Protocol Configuring IPoIB Interfaces Converting Sockets-Based Application Explicit/Source Code Conversion Type Automatic Conversion Type Log Statement Match Statement SDP Performance Page Netperf Server with IPoIB and SDP Page Page uDAPL Introduction uDAPL Test Performance uDAPL Throughput Test Performance uDAPL Latency Test Performance Compiling uDAPL Programs MVAPICH MPI Initial Setup Configuring SSH Page Page Editing Environment Variables Setting Environment Variables in System-Wide Startup Files Editing Environment Variables in the Users Shell Startup Files Editing Environment Variables Manually MPI Bandwidth Test Performance MPI Latency Test Performance Intel MPI Benchmarks (IMB) Test Performance Page 7-11 When the test completes successfully, you see output similar to the following: Compiling MPI Programs Page Page HCA Utilities and Diagnostics hca_self_test Utility Page tvflash Utility Viewing Card Type and Firmware Version Upgrading Firmware 8-5 Diagnostics Page APPENDIX A Acronyms and Abbreviations Page INDEX A B C D E H I K L M N O P R S T U V W
