Re: Socket Direct Protocol: help (2)
Hi, FMR are being used only in a special mode called ZCopy. You could disable this mode by setting the module paramter sdp_zcopy_thresh to 0, or by issuing: # echo 0 /sys/module/ib_sdp/parameters/sdp_zcopy_thresh This means that you won't get the benefits of Zero-copy. - Amir On 04/14/2010 11:51 AM, Andrea Gozzelino wrote: On Apr 13, 2010 10:22 PM, Tung, Chien Tin chien.tin.t...@intel.com wrote: Chien, does the NE020 support FMRs?

Re: Socket Direct Protocol: help (2)
Hey Amir, I don't think this helps because sdp_add_device() will not add rdma devices that fail to create fmr pools. So I guess you could key off of fmr pool failures and set sdp_zcopy_thresh to 0 and allow the device to be used? But what we really need is sdp support for fastreg_mrs as an alternative to fmrs.

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.

Could be a firmware problem?
