CPU and System Topology
Server Description
A GPU-accelerated virtual server featuring dual dedicated accelerators, local SSD storage, and balanced system memory for parallel computing workloads.
Alibaba Cloud ecs.gn5-c8g1.4xlarge is a GPU-accelerated instance designed for parallel computing workloads. It features 16 dedicated vCPUs from an Intel Xeon E5-2682 v4 processor running at 2.5 GHz, paired with 120.0 GB of system memory. The hardware configuration includes two NVIDIA Pascal P100 GPUs with a total of 32 GB VRAM, alongside a 944 GB local SSD and a 5 Gbps baseline network bandwidth. Benchmark data reveals modest single-core CPU performance, but stable multi-core and memory bandwidth capabilities, including a multi-core stress-ng score of 9532.02 and 10.88 million Redis SET operations per second. This instance is qualitatively cost-efficient for legacy GPU-accelerated tasks, scientific simulations, and database workloads that leverage dedicated hardware accelerators and local SSD storage rather than demanding high single-threaded CPU speeds.
