[dpdk-dev] Issues with running multicore
Hi All,
Iam trying to create multi core application by mapping separate function for
each core.
I had followed Multi process example and I had used pthread.
The use case is:
1. In a single process, launch pthread and run rte_eal_init
2. Once rte_eal_init is done, create 3 pthreads
3. Launch master core.
4. In each of 3 pthread, launch slave core.
The issue is, I don't see 4 cores running. Instead I see only single core
running.
Here is the Pseudo code:
Init_pmd{
ret = rte_eal_init(args, argv) ==> I had set the number of cores to 4 in the
params.
pthread_create(&thread1, NULL, (void*)threadFun1, NULL);
pthread_create(&thread2, NULL, (void*)threadFun2, NULL);
pthread_create(&thread3, NULL, (void*)threadFun3, NULL);
rte_eal_mp_remote_launch(launch_pmd_single_lcore, NULL, CALL_MASTER);
}
Iam mapping each core to threadFun1, threadFun2 and threadFun3.
threadFun1
{
RTE_LCORE_FOREACH_SLAVE(lcore_id)
{
if( lcore_id == 1 )
rte_eal_remote_launch(threadFun1_launch_one_lcore, NULL, lcore_id);
}
}
Has anyone seen this issue?
Please let me know if iam missing something?
Thanks

If you want to do these more complex manipulations uthash is probably a better route. But it will be slower than the DPDK hashes by quite a ways I think. I used DPDK hash for my TCP socket table where everything is a very predictable size, but I had to use uthash for my unpredictably sized byte buffers for security indicators (IP, URL, Domain, Email, File Hash, etc.) Of course, when you do this kind of stuff in your app it is going to give you scaling problems and you'll have to spend a lot of time tuning it.

HI Bruce, Thanks for your inputs. I am wondering why Cuckoo hash is pushing the entry into new bucket why not add a new entry in the same bucket ?

The current DPDK hash library does not support this, unfortunately. There is currently an effort underway to do a cuckoo hash implementation for DPDK (patches already on-list), to allow items to move between buckets rather than just failing if a bucket is full. Please feel free to try out these patches and provide feedback on them if you can! /Bruce >

[dpdk-dev] KNIC to Kernel IP interface mapping
HI Is there any many to one mapping schemes available for KNIC interface. Let's say I have 5 kernel IP interfaces and I want to map all the five interfaces to one KNIC (single KNIC), so we can transmit all the frames to KNIC from all the five kernel IP interfaces and when we get the packet from forwarding plane we can put the packet into KNIC and give the packet to corresponding Kernel IP interfaces. We have one to one mapping available according to the documentation but if I have too many IP interfaces I don't want to use too many KNIC as well to provide one to one mapping Thanks in advance! Please let me know if you have any suggestion/ideas to solve this problem! Thanks Jaffar
