Hi,
I'm trying to configure qos-policy.donc file for service-id use.
I've tried basic RDMA_PS_TCP service-id level with service id 0x0106
[]# cat /etc/opensm/qos-policy.conf
qos-levels
qos-level
name: DEFAULT
sl: 0
end-qos-level
qos-level
name: TCP
sl: 4
end-qos-level
qos-level
name: MPI
sl: 5
end-qos-level
end-qos-levels
qos-ulps
default : 0 # default SL
any, service-id 0x0000000001060000- 0x000000000106FFFF : 4
end-qos-ulps
I add this rule in my configuration and check by mapping
sl 4 on a vl with a weight of 0
# QoS default options
qos_max_vls 8
qos_high_limit 1
qos_vlarb_high 0:1,1:0,2:0,3:0,4:0
qos_vlarb_low 0:1,1:2,2:4,3:8,4:0,5:32
qos_sl2vl 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15
I've launched qperf on the server side
and listen on client:
j=100; for i in $(seq 0 $j) ; do /usr/bin/qperf -ri mlx4_0:1 -li mlx4_0:1
10.12.1.4 -sl 4 -lp 20004 rc_bw; done;
rc_bw:
bw = 0 bytes/sec
rc_bw:
bw = 0 bytes/sec
j=100; for i in $(seq 0 $j) ; do /usr/bin/qperf -ri mlx4_0:1 -li mlx4_0:1
10.12.1.4 -sl 5 -lp 20005 rc_bw; done;
rc_bw:
bw = 3.37 GB/sec
rc_bw:
bw = 3.37 GB/sec
Qperf gives me results I expected due to qos-level configuration part,
but no
expected results using qperf tcp_bw, bandwith is not
filtered/blocked by sl weight.
# j=100; for i in $(seq 0 $j) ; do /usr/bin/qperf 10.12.1.4 tcp_bw; done;
tcp_bw:
bw = 923 MB/sec
tcp_bw:
bw = 935 MB/sec
j=100; for i in $(seq 0 $j) ; do /usr/bin/qperf -ri mlx4_0:1 -li mlx4_0:1
10.12.1.4 -sl 5 -lp 20005 rc_bw; done;
rc_bw:
bw = 2.23 GB/sec
rc_bw:
bw = 2.24 GB/sec
rc_bw:
bw = 2.21 GB/sec
Could you help me to understanding service-id mechanism or give me a
relevant
test to test TCP service id level ?
Thanks.
Céline Bourde.
