+## PDS-H (TPC-H variant)
+
+The steps below reproduce the PDS-H benchmark results using cudf.pandas.
+
+### Setup
+
+Install `cudf` following the
+[RAPIDS installation guide](https://docs.rapids.ai/install). For nightly wheels:
+
+```bash
+CUDA_MAJOR=$(nvidia-smi | grep -oP 'CUDA Version: \K[0-9]+')
+pip install --extra-index-url https://pypi.anaconda.org/rapidsai-wheels-nightly/simple \
+    "cudf-cu${CUDA_MAJOR}>=0.0.0a0"
+```
+
+Then install `tpchgen-cli`, a Rust-based TPC-H data generator used to produce the benchmark
+dataset as Parquet files:
+
+```bash
+pip install tpchgen-cli
+```
+
+### Generate data
+
+Set the scale factor once and reuse it across all steps. The following generates SF50
+(scale factor 50, roughly 50GB of data):
+
+```bash
+export SCALE_FACTOR=50.0
+export DATA_PATH="data/tables/scale-${SCALE_FACTOR}"
+
+tpchgen-cli parquet -o "${DATA_PATH}" -s ${SCALE_FACTOR}
+```
+
+`tpchgen-cli` generates Decimal and `datetime.date` columns. pandas cannot use these types
+in arithmetic, so convert them to float64 and timestamp before running the benchmark. This
+conversion step may not be needed in the future (see [#21204](https://github.com/rapidsai/cudf/issues/21204)).
+
+```python
+from pathlib import Path
+import pyarrow as pa
+import pyarrow.parquet as pq
+import os
+
+data_path = Path(os.environ["DATA_PATH"])
+tables = ["lineitem", "orders", "customer", "supplier", "part", "partsupp", "nation", "region"]
+
+def cast_schema(schema):
+    return pa.schema(
+        f.with_type(pa.float64()) if pa.types.is_decimal(f.type)
+        else f.with_type(pa.timestamp("ms")) if pa.types.is_date(f.type)
+        else f
+        for f in schema
+    )
+
+for table in tables:
+    table_path = data_path / f"{table}.parquet"
+    parts = [table_path] if table_path.is_file() else sorted(table_path.glob("*.parquet"))
+    for part in parts:
+        tbl = pq.read_table(part, schema=cast_schema(pq.read_schema(part)))
+        pq.write_table(tbl, part)
+```
+
+### Run
+
+**CPU** (`--executor cpu`, pandas):
+
+```bash
+python -m cudf.pandas._benchmarks.pdsh all \
+    --executor cpu \
+    --path "${DATA_PATH}"
+```
+
+**GPU** (`--executor in-memory`, cudf.pandas):
+
+```bash
+python -m cudf.pandas._benchmarks.pdsh all \
+    --executor in-memory \
+    --path "${DATA_PATH}"
+```
+
+### Results
+
+Results are written to `pdsh_results.jsonl` in the current directory by default (override with `-o`).
+Each run appends one JSON line containing metadata and a `records` field with per-query,
+per-iteration timings:
+
+```json
+{
+  "query_set": "pdsh",
+  "executor": "in-memory",
+  "dataset_path": "data/tables/scale-50.0",
+  "scale_factor": 50,
+  "records": {
+    "1": [
+      {"query": 1, "iteration": 0, "duration": 0.79, "status": "success"},
+      {"query": 1, "iteration": 1, "duration": 0.55, "status": "success"}
+    ]
+  }
+}
+```
+
+`duration` is in seconds. Running multiple executors with the same `-o` file appends each as a
+separate line, making it easy to compare CPU and GPU results in one file.
