Hi,
I am currently facing issue in brining up DPDK application. It is failing with the following message. rte_errno is set to 12 in this scenario. (Out of memory).
It would be great if you can kindly point me to what am I doing incorrectly.
I am using DPDK 2.2.0 version on ubuntu 16.04.

Have you tried allocating memory on both numa nodes to rule that out?

The DPDK email etiquette is to not top-post.
The DPDK drivers and libraries are going to allocate memory in general
on the same numa node as where the device is present. Some resources will
allocate memory on socket 0 the default socket.
In a numa environment, then you need to have some memory on socket 0
and the bulk of it on the same as your device. Not all nodes need
to have the same reserved memory.

Hi Cliff,
But I want to allocate memory on only NUMA node where my lcore's and DPDK NICs are connected.
I think this gives the most optimized performace when everything is connected to the same NUMA node.
Thanks,
Raghu

Hi Cliff,
Yes, I had tried it.
When I set memory on both NUMA nodes it works without this issue.
I set using the following commands:
root@rg2-14053:/home/adara/raghu_2/dpdk-2.2.0# echo 128 > /sys/devices/system/node/node1/hugepages/hugepages-2048kB/nr_hugepages

Hi Cliff,
Yes, I had tried it.
When I set memory on both NUMA nodes it works without this issue.
I set using the following commands:
root@rg2-14053:/home/adara/raghu_2/dpdk-2.2.0# echo 128 > /sys/devices/system/node/node1/hugepages/hugepages-2048kB/nr_hugepages
root@rg2-14053:/home/adara/raghu_2/dpdk-2.2.0# echo 128 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
root@rg2-14053:/home/adara/raghu_2/dpdk-2.2.0#
root@rg2-14053:/home/adara/raghu_2/dpdk-2.2.0# cat /sys/devices/system/node/node1/hugepages/hugepages-2048kB/nr_hugepages
128
root@rg2-14053:/home/adara/raghu_2/dpdk-2.2.0# cat /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
128
Thanks,
Raghu
