# cpufp
This is a cpu tool for benchmarking the peak performance of floating-points and AI ISAs.
It can automatically sense the local SIMD|DSA ISAs while compiling.

## Support e2k ISA
| Arch | ISA |Feature| Vector Width | Data Type |Description
|:-----|:------|:-----:|:------------:|----------:|:----------
| SIMD | v6 | Vector| 128 | fp32/fp64 | FMA
| SIMD | v5 | Vector| 128 | fp32/fp64 | Combined operations
|Scalar| v1-v4 | Scalar| | fp64 | Combined operations
| SIMD | v1-v4 | Vector| 64 | fp32 | Combined operations
### Combined operations
E2K has support for instructions that perform two independant operations.
It is like FMA, but with additional rounding as these operations is independant.
#### Example `fmul_addd`
```
fmul_addd src1, src2, src3, dst
```
##### Description
Multiply double-precision (64-bit) floating-point values from `src1` and `src2`,
and add the intermediate result to value from `src3`. Store the result in `dst`.
##### Operation
```
dst[63:0] := src3[63:0] + src1[63:0] * src2[63:0]
```
##### Latency and Throughput
| Architecture | Latency | Throughput (CPI) | ALC
|:--------------|:-------:|:----------------:|:---:
| elbrus-v4 | 8 | 0.16 | `012345`
| elbrus-v1 | 8 | 0.25 | `01-34-`
* ALC (Arithmetic Logic Complex/Channel) is an execution port for RISC-like instructions
## How to build
build x64 version:
`./build_x64.sh`
build arm64 version:
`./build_arm64.sh`
build riscv64 version:
`./build_riscv64.sh`
build loongarch64 version:
`./build_loongarch64.sh`
build e2k version:
`./build_e2k.sh`
clean:
`./clean.sh`
## How to benchmark
`./cpufp --thread_pool=[xxx] --idle_time=yyy`
--thread_pool: [xxx] is the list of cpu thread to benchmarking, from setting affinities. Please reference the result of lstopo command. For example, [0,3,5-8,13-15].
--idle_time: the interval time(sec) between any two adjacent benchmarks, default is 0.
