CPU and System Topology
Server Description
A dedicated 32-vCPU compute-focused instance balancing multi-threaded processing capabilities with a 1:2 memory-to-core ratio and no local storage.
Alibaba Cloud ecs.u1-c1m2.8xlarge is an x86_64 compute-optimized server instance featuring 32 dedicated vCPUs and 64.0 GB of RAM, powered by an Intel Xeon processor at 2.5 GHz. Operating under the KVM hypervisor, it lacks local storage and GPU accelerators, utilizing a 10 Gbps baseline network interface. Performance benchmarks indicate a distinct tradeoff: single-core execution is weak, placing in the bottom 25%, while multi-core performance, memory bandwidth, and database operations consistently achieve average, mid-tier results. This hardware profile is suited for parallelized workloads such as multi-threaded software compilation, image processing, and Redis database operations that can utilize the 32 vCPUs effectively, offering a qualitative balance of compute density without the added cost of local storage or specialized accelerators.
