[ofa-general] uDAPL question

[Yong Qin]

Is there any progress on this issue? We are seeing exactly the same
error on OFED 1.1 + Intel MPI 3.0 -- "unexpected DAPL event 4006" and
wondering if there is a fix.

Thanks,

Yong

Hi Woody,

Thanks for your help.
I guess the problem is in the CM - is it ?
Can you point me to relevant communication/bug reports that explain the
fix for this issue ?
Would Sean be the right person to ask regarding what exact patch should
be added/removed ?
I would prefer to stick to OFED-1.1 code with minimal changes - if
possible -
to avoid compatibility issues. 

Thanks,
Boris

This is a known problem and should be fixed by now, There was a bad
patch that somehow got into OFED that was not in Sean main tree.
Assuming this bad patch has been removed, the problem should be fixed.

Hi, 
 
I'm trying to get simple Intel MPI benchmark running over IB (uDAPL)
using OFED-1.1 stack.
I'm consistently getting the following error:
 
[root at ibd005 ~]# ./runjob_I_MPI.boris 2
Task 0 of 2 tasks started on host ibd005.ibd.mti.com clock_resolution =
1.00e-06 s Task 1 of 2 tasks started on host ibd006.ibd.mti.com
[0:ibd005] unexpected DAPL event 4006 from 1:ibd006 [1:ibd006]
unexpected DAPL event 4006 from 0:ibd005
rank 0 in job 14  ibd005_36193   caused collective abort of all ranks
  exit status of rank 0: return code 254 

I did some digging and found out that event 4006 (actually 0x4006) means
DAT_CONNECTION_EVENT_BROKEN and it is returned by function dat_rmr_bind.

So my question is why this function consistently fails.
I'm using standard dat.conf file:
 
OpenIB-cma u1.2 nonthreadsafe default
/usr/local/ofed/lib64/libdaplcma.so mv_dapl.1.2 "ib0 0" ""

Appreciate your help,
 
Boris Shpolyansky
