I have the same problem... It has been solved? Can I get the solution?
Hi, we encountered a similar problem when trying to reproduce Freeflow with the MT27710 family [ConnectX-4 ]. Do you have any suggestions for this problem?
Problem
I'm reproducing freeflow on my own machine, and when I run ib_send_bw in two containers located at the same physical machine,
Floating point exception(core dump)
occured. The error is also in two containers located at two machines while these two machines can run ib_send_bw correctely. I am strictly following the quick start of github. Here is my environment and how I run freeflow.Environment
host IPs and virtual IP to host IP mapping
I have two machines, 192.168.2.203 and 192.168.2.206. They are connected by weave overlay.I have modied host IPs and virtual IP to host IP mapping in my code. In ffrouter.h#L76,
In ffrouter.cpp#L215,
Implementation
At host 203, enter freeflow router container and excute
./router router1
, and run a container named node1, whose ip is10.47.128.0
, and runib_send_bw
. At host 206, enter freeflow router container and excute./router router1
, and run a container named node2, whose ip is10.47.0.8
, and runib_send_bw 10.47.128.0
. Then the error happened. In container which runib_send_bw
, log is In container which runib_send_bw 10.47.128.0
, log is How should I solve it? And can you tell me your gcc version ?
