5 GPU-as-a Service Project Asaka

6 What is GPU & GPGPU? Graphical Processing Unit Designed for Parallel Processing Latency: Increase Clock Speed Throughput: Increase Concurrent Task Execution General-Purpose GPU Why: Scientific Computing and Graphical processing => Matrix & Vector Prerequisite: key feature supported in GPU, such as float point computing Easy to use: CUDA => Theano, Tensorflow and etc. Popular use-case: Scientific Calculation, ML/DL, Crypto, Bitcoin and etc. 6

7 Problems today Not widely deployed High cost Low availability when sharing Hard to monitoring in fine-grained Remote GPU as a Service Fine-grained resource control Sharable Fine-grained resource monitor and tracing Offering GPU in cloud makes it more complex: How to abstract GPU resource? Pass-through solution today Performance issues caused by network Resource discovery and provisioning 7

8 Project Asaka - GPU as a Service Remote GPU Access Consume remote GPU resource transparently Based on queue model and various network fabric GPU Sharing N:1 model: multiple user consume same GPU accelerator Fine-grained control and management GPU Chaining 1:N model: multiple GPU hosts chaining as one to serve a large size to 1 application; Dynamical GPU number fit to application Smart Scheduling GPU pooling, discovery and provision Fine-grained resource monitor and tracing Pluggable intelligent scheduling algorithms: o Heterogeneous resource o Network tradeoffs 8

9 How to access remote GPU transparently? Transparent remote GPU resource access: C Asaka CUDA APIs CUDA APIs interception CUDA APIs Fine grained GPU resource management and control: vgpu -side GPU resource chaining Intelligent selection of network fabric: TCP or RDMA Asaka GPU Library vgpu Network (TCP, RDMA) Asaka CUDA APIs C CUDA APIs Compatible with existed CUDA applications Asaka GPU Library vgpu Asaka CUDA APIs Client Network Fabric 9 C : CUDA Application

10 How to manage GPU pool and scheduling? Pooling and managing GPU resources: Consul based Add/remove node, failure detection, resurrect GPU scheduling challenges: Two-level dispatching: 1 st level: Find GPU hosts 2 nd level: CUDA request to devices GPU server chaining Network Strategy Host Dispatcher Q-Length Strategy H-Res Strategy Intelligent Analysis Client Application Asaka GPU Library Distributed Global State Store Global intelligence and smart scheduling: Global status monitor and tracing Frontend Network topology analysis Queue-based priority profile Pluggable scheduling algorithms Tasks Queue Smart Dispatcher 10

11 How to integrate with Cloud Native Platform? Offering allocation strategies as a service: High-level abstraction of scheduling functions 3. Execute the Job Cluster Manager 1. Job requests Allocation API Global Scheduler XaaS_Controller Non-invasive design, easy to integrate with existed schedulers in Cloud Native Platform Access GPU transparently from applications deployed in Cloud Native Platform 4. Transparently consume GPU as a service Ease of integrating to Cloud Native Platform Sync nodes attributes & status 2. Allocation Strategies : Job : Allocation Strategy 11

13 Cloud Foundry What is it and why should I care?

14 Let Daily me Struggle solve that for you Need to MOVE at a faster pace Constant Requests New Machines New Databases New Services Manual Installation Processes Things Crashing Developers writing crappy code Software Platform for rapid pace Self Help Marketplace Automated Orchestration High Availability with Scalability Enforces good software pattern Identical Environments for Dev, Test and Production 14

15 What is Cloud Foundry? Cloud Foundry DevOps CLI Web GUI Cloud Controller Diego Brain Loggregator Marketplace Diego Cell Diego Cell Router Users 15

16 Cloud Foundry Marketplace Fully Self Serviced Industrial standard services available Different Service Levels Charge back based on Usage Easy API 16

17 Cloud Foundry with Asaka Run my app with GPU! I don t care how!

18 But why? New Requests for GPU Manual Management and Orchestration No Network Traffic Control Hard to predict budget Not releasing GPU GPU dependent App cannot run on CF Self-Service Marketplace Automates orchestration of entire stack Centralize Compute Location Pay and use as you go Easy GPU Service Provision GPU Access from Cloud Foundry! 18
