Dstack - Performance and Accuracy
Performance
Dstack’s performance, particularly with AI models like Llama 3.1 405B, is highlighted in benchmarks involving AMD MI300X GPUs. Here are some key points:Throughput and Time to First Token (TTFT)
Throughput and Time to First Token (TTFT): In benchmarks using 8x AMD MI300X GPUs, the TGI backend consistently outperforms the vLLM backend in terms of token throughput and TTFT, especially for larger batch sizes and sequence lengths. For instance, TGI shows significant advantages in throughput and TTFT as the batch size increases beyond 64 tokens.Batch Size and Context Size
Batch Size and Context Size: The performance difference between TGI and vLLM becomes more pronounced with larger batch sizes and context sizes. For example, with prompts of 10,000 tokens, TGI demonstrates better performance in both throughput and TTFT.Requests Per Second (RPS)
Requests Per Second (RPS): At higher request rates, TGI generally outperforms vLLM, although it starts to drop requests at very high RPS (e.g., 5 RPS), indicating some limitations in handling extremely high request volumes.Memory and Resource Utilization
Memory Saturation
Memory Saturation: Benchmarks comparing NVIDIA H100 and AMD MI300X GPUs show that the MI300X can handle larger prompts and batch sizes before hitting memory saturation. However, when memory saturation is reached, the inference engine has to compute or offload tensors, which degrades throughput.GPU Utilization
GPU Utilization: The AMD MI300X GPUs, with their high memory capacity (192 GB) and peak memory bandwidth (5.3 TB/s), are well-suited for large AI models, allowing for efficient use of vRAM, especially for larger batches.Limitations and Areas for Improvement
Request Dropping
Request Dropping: At higher request rates, TGI may drop requests, which can affect the accuracy of throughput and TTFT measurements. This issue needs further investigation to ensure reliable performance under high load conditions.Backend Configuration
Backend Configuration: The performance of vLLM could potentially be improved with better backend configuration tuning, which was not fully explored in the benchmarks.Resource Matching
Resource Matching: Ensuring that the configuration does not set conflicting resource requirements is crucial. For example, specifying exact resource values can limit the selection of instances, and setting resource ranges can help match more instances.Feature Support
Feature Support: Some features of Dstack may not be supported by all backends, which can limit the selection of instances and affect performance. Ensuring that the chosen backend supports all necessary features is important. In summary, Dstack demonstrates strong performance with AI models, particularly when using the TGI backend and AMD MI300X GPUs. However, there are areas for improvement, such as handling high request rates without dropping requests and ensuring optimal backend configurations. Additionally, careful resource matching and feature support are essential for maximizing performance. Dstack - Pricing and Plans
