Good morning,
I'm testing some Neteffect cards (Intel code E10G81GP - Neteffect
NE020.LP.1.SSR).
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.
Thank you very much,
Andrea
