Inspector tasks

Container images built from the images/ folder of the sc-images repository.

Benchmark

Image	Description
benchmark	General CPU, memory, and compression benchmarks: Geekbench, OpenSSL speed, lmbench memory bandwidth (bw_mem), and compression of the Silesia corpus.
benchmark-ffmpeg	FFmpeg transcoding-capacity benchmark of audio and H.264/H.265 video encoding.
benchmark-llm	Low-concurrency LLM inference speed benchmark with llama.cpp's llama-bench, measuring prompt processing and text generation across models and token counts.
benchmark-passmark	PassMark PerformanceTest CPU and memory benchmark suite.
benchmark-pgbench-postgres	PostgreSQL database benchmark focusing on CPU and memory performance, measuring transactions per second and latency against a local or remote server.
benchmark-redis	Redis 7.4 in-memory key-value store benchmark.
benchmark-storage	Raw block device benchmark with fio, testing each distinct disk type of the host and multi-disk groups concurrently.
benchmark-vllm-cpu	High-concurrency LLM inference benchmark with vLLM and GuideLLM, targeted CPUs with AVX-512.
benchmark-vllm-cpu-avx2	High-concurrency LLM inference benchmark with vLLM and GuideLLM, targeted CPUs with AVX2 but no AVX-512.
benchmark-vllm-gpu	High-concurrency LLM inference benchmark with vLLM and GuideLLM, using tensor parallelism across all available GPUs.
benchmark-web	Static web server benchmark, serving files with binserve and measuring throughput and latency with wrk.
nvbandwidth	NVIDIA GPU memory bandwidth benchmark with nvbandwidth, measuring host-to-device and device-to-device copy speeds.
stress-ng	CPU benchmark running stress-ng stressors and counting their operations per second.
stress-ng-longrun	Pinned stress-ng version for the 24-hour long-running benchmark.

Hardware discovery

Image	Description
dmidecode	Reads the server's DMI/SMBIOS tables with dmidecode to report hardware details such as memory modules and firmware.
hwinfo	Collects CPU, memory, and topology details with lshw and hwloc, plus the measured CPU frequency.
virtualization	Checks whether the server supports KVM hardware virtualization and reports the result as JSON.

Base

Image	Description
resource-tracker	Spare Cores resource-tracker binary, copied into the other images to record resource usage while benchmarks run.
vllm-cpu-base-avx2	vLLM CPU build for x86_64 hosts with AVX2 but no AVX-512, used as the base of benchmark-vllm-cpu-avx2.

Service

Image	Description
benchmark-postgres-server	PostgreSQL 18 server running at high priority, used as the remote target of database benchmarks.
llama.cpp	llama.cpp server (llama-server) with CUDA support, built from a pinned commit.
