PC has Linux| (kernel version) 2.6.18-164.15.1.el5 | x86_64 x86_64 x86_64 GNU/Linux. In this phase, I measure the bandwidth with the netserver/nerperf (version netperf-2.4.5) ad hoc tests. They work fine with TCP protocol - as OFED 1.5.1 example programs - and they have some problems with SDP one. I'm trying test with the command lines below: server: LD_PRELOAD=/usr/local/lib64/libsdp.so netserver client: LD_PRELOAD=/usr/local/lib64/libsdp.so netperf -H server_address -c -C -- -m 65536 The /etc/libsdp.conf file contains rules below: use both listen * *:* use both connect * *:* log min-level 9 destination file libsdp.log Client displays "Connection error: Can not allocate memory" and the connection fails. (original text on client log file:libsdp Error connect: failed for SDP fd:6 with error:Cannot allocate memory) The library path is: /usr/local/lib64/libsdp.so Could someone explain me how LD_PRELOAD environment variable must be set? I don't understand why the test work with TCP and not with SDP. Could I work with wrong Linux kernel environment or parameters? I don't know if there is a specific mailing list for SDP so I ask you help.
