kandi X-RAY | dpctl Summary
. Data Parallel Control (dpctl) is a Python library that allows a user to control the execution placement of a [compute kernel] on an [XPU] The compute kernel can be either a code written by the user, e.g., using numba-dppy, or a code that is part of a library like oneMKL. The dpctl library is built upon the [SYCL standard] and implements Python bindings for a subset of the standard [runtime classes] that allow users to query platforms, discover and represent devices and sub-devices, and construct contexts and queues. In addition, dpctl features classes for [SYCL Unified Shared Memory (USM)] management and implements a tensor [array API] The library also assists authors of Python native extensions written in C, Cython, or pybind11 to access dpctl objects representing SYCL devices, queues, memory, and tensors. Dpctl is the core part of a larger family of [data-parallel Python libraries and tools] to program XPUs. The library is available via [conda] and [pip] It is included in the [Intel Distribution for Python*] (IDP).

- Is the total number of incoming packets equal to (lookups.hit + lookups.missed)?
Yes. (Plus lookups.lost except that I see that's zero for you.)
- If the total number of incoming packets is equal to (lookups.hit + lookups.missed), why is the value of masks.hit:39862430 greater than (lookups.hit:37994604 + lookups.missed:218759)?
masks.hit is the number of hash table lookups that were executed to process all of the packets that were processed. A given packet might require up to masks.total lookups.
- Why is the masks.hit/pkt ratio greater than 1? What is the reasonable value in what interval?
The ratio cannot be less than 1.00 because that would mean that processing a packet didn't require even a single lookup. A ratio of 1.04 is very good because it means that most packets were processed with only a single lookup. Higher ratios are worse.

QUESTION
I am running a switch test Switch Test on real environment with one openvswitch and real sdn switch.
I created a bridge on openvswitch and added ports (ex. eth0, eht1). But I want to know logical port numbers (like 1, 2) which command gives me correct information. ovs-ofctl show bridge s1
shows

QUESTION
I downloaded mininet, opendaylight, etc.. and I wanted to add flow table to switches.I used dpctl
and sh ovs-ofctl
command. but it was too hard to add flow tables to each switches.
I want to add flow table on Dlux UI. But I don't know how to fill in that blank. I made a topology by:
sudo mn --controller=remote,ip=127.0.0.1,port=6633 --switch ovsk --topo tree,2,2
I could see the Node Id of switches. it was "openflow:1","openflow:2","openflow:3"
So i input openflow:1.. but it occured an error! i don't know how to fill that blank
