We are glad to propose to you an exciting challenge “Deterministic Scheduling for Extended Reality over 5G and Beyond”, which is prepared by Huawei Wireless Product Line.
In this contest, we focus on a XR-service scheduling problem to maximize the total number of successfully transformed XR-data frames under specific transmission requirements. Extended reality (XR) is an umbrella term for different types of realities such as virtual reality (VR), augmented reality (AR), and mixed reality (MR), which can provide people with immersive experience. To achieve better user-experience, scheduling algorithm should be proposed to efficiently utilize the limited radio resources, e.g., time resource, frequency resource, and power resource. Due to several practical constraints, the scheduling task is a typical NP-hard problem.

This time we’re delighted to provide you with a new challenging problem from Huawei — Buffer Sharing in Multi-Tenant Database Environment, which is prepared by Huawei 2012 Labs and Huawei Cloud Computing.
Nowadays everyone uses databases directly or indirectly. For example, databases of service providers store shopping records, transaction records, or ticket purchase records. During this challenge, you will work with the multi-tenant database, in which a single database instance is divided into multiple virtual sub-databases, serving different tenants of cloud service.
In such databases, different tenants need to be isolated from each other to prevent services from affecting each other. Therefore, buffer is considered as an important resource for management of large amount of data. When the amount of data in the database buffer reaches the maximum value, the database buffer evicts some data from the memory based on the eviction algorithm and loads new data pages from the disk. Your goal is to optimize sharing and isolation of database buffers in the multi-tenant database. While replacement algorithms considered in this contest be one of the core algorithms, we believe there are multiple approaches one can try here, and some crossover of the algorithms will also increase your chances to win!

Benchmarks are popular for estimating and comparing the performance of computer systems which has always been a challenging task faced by computer architects and researchers. However, it is known that as emerging applications evolve, benchmark characteristics drift with time and an optimal design using benchmarks of today may not be optimal for applications of tomorrow. This problem has been aptly described as: “Designing tomorrow’s microprocessors using today’s benchmarks built from yesterday’s programs”. One of the approaches for addressing these challenges is to complement application benchmark suites with synthetic benchmarks.
Program control flow generation algorithm is one of the most difficult questions for synthetic benchmarks. Hence, this problem focuses on generating program control flow for synthetic benchmarks based on MIC related to behavior of conditional branch instructions. In this question, program control flow generation is abstracted to draw a route on a directed graph. The route and the graph with MIC closest to the input will be the winner.
This is a problem about job scheduling and data assignment. Consider a scenario, where we want to run a complicated software project, on a computing cluster or on a multi-core heterogeneous computing chip. The computing cluster has multiple computing units of various computing power, as well as multiple memory disks with various reading and writing speed. The software project consists of many small computing tasks with inter-dependence among them. During the execution, these tasks will also produce data that need to be stores onto some memory disks. Our goal is to design an efficient task scheduling algorithm, that is able to assign the tasks to different computing units, and to store the data to different memory disks, such that the overall makespan, which is the time the finish the last task, is minimized. As you can imagine, usually when a task starts its execution, it needs to first read the necessary data from the memory disks, and when the computation completes, it will then write its own data to some memory disk for other tasks to read. This means, the schedule of tasks to computing units, and the assignment of data to memory disks are tightly connected to each other, and they will together decide the overall running time of the whole software project.

This time HUAWEI has prepared 2 challenging tasks for you from different business domains – Data Communication and Cloud.
You are free to choose which problem you would like to solve, and you are also welcome to solve both problems, but please remember the total runtime of both rounds, which start simultaneously, is 15 days only. We hope you'll enjoy this complex yet very exciting Challenge!
Each problem will have its own scoreboard and its own prize fund, so this is a unique chance for you to win double prizes for two solved problems!
This problem comes from HUAWEI’s Data Communication business domain, in which routing algorithms have always been a critical issue. In the future, as more and more communication devices are connected to networks, data communication will face an interconnected network formed by ultra-large-scale network devices.
In this challenge, data communication experts of HUAWEI will provide you several network topologies. By dividing them into abstract domains, you need to scale down these topologies and enable quick route calculation, so that fast route convergence can be implemented on large-scale networks. Domain division must address the optimal routing and network scale constraints, so a routing algorithm that effectively divides domains while also meeting these constraints is the core of the algorithm design.
This problem comes from another HUAWEI’s business domain – Huawei Cloud. To win the competition in cloud computing market, major cloud service providers are focusing on improving the utilization of cloud resources, as this will allow to reduce the cost of cloud services. It is estimated that even a 1% increase in cloud service resource utilization can save millions of dollars in costs. The optimization of resource utilization, in turn, requires the development of advanced algorithms and technologies for cloud resource management.
The virtual machine (VM) placement algorithm considered in this contest is one of these critical algorithms, which is used to select a physical machine for running a user VM. Since VM requests arrive dynamically, this algorithm works in online fashion. The main goal is to maximize the number of successfully placed VMs. As the algorithm runs on a resource pool of fixed size the more requests are allocated, the less resources are wasted and the more resource efficient is the algorithm. A secondary goal is to maximize the number of VMs placed without violation of additional soft constraints, as it improves the cloud user experience.
