Benchmark Milk-V Mars RISC-V SBC

[geerlingguy]

See: geerlingguy/sbc-reviews#46

It will likely be similar in performance to the Mars CM (#20)

Attempting to install Ansible to run the benchmark from the board itself:

1. sudo apt install python3-pip
2. pip3 install ansible

For the Mars CM, it had trouble compiling the Python cryptography library. And I found an issue for riscv64 build - OOM kill, high memory usage, but I seem to be hitting an issue where it tries to find a Rust compiler and bails:

      copying src/cryptography/hazmat/bindings/_rust/openssl/x448.pyi -> build/lib.linux-riscv64-cpython-310/cryptography/hazmat/bindings/_rust/openssl
      running build_ext
      running build_rust
      error: can't find Rust compiler
      
      If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it. Installing from the wheel would avoid the need for a Rust compiler.
      
      To update pip, run:
      
          pip install --upgrade pip
      
      and then retry package installation.
      
      If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain.
      
      This package requires Rust >=1.63.0.
      [end of output]
  
  note: This error originates from a subprocess, and is likely not a problem with pip.

I tried installing musl-dev with gcc musl-dev python3-dev libffi-dev as suggested here, then I tried installing cryptography standalone, but that's not working either.

Going to just run Ansible from my Mac like I did with Mars CM.

[geerlingguy]

Running from my Mac, it gets stuck during the apt cache update, so I've disabled that for now...

Final result: 2.058 Gflops at 4.7W, for 0.438 Gflops/W

An explanation of the input/output parameters follows:
T/V    : Wall time / encoded variant.
N      : The order of the coefficient matrix A.
NB     : The partitioning blocking factor.
P      : The number of process rows.
Q      : The number of process columns.
Time   : Time in seconds to solve the linear system.
Gflops : Rate of execution for solving the linear system.

The following parameter values will be used:

N      :   23314
NB     :     256
PMAP   : Row-major process mapping
P      :       1
Q      :       4
PFACT  :   Right
NBMIN  :       4
NDIV   :       2
RFACT  :   Crout
BCAST  :  1ringM
DEPTH  :       1
SWAP   : Mix (threshold = 64)
L1     : transposed form
U      : transposed form
EQUIL  : yes
ALIGN  : 8 double precision words

- The matrix A is randomly generated for each test.
- The following scaled residual check will be computed:
      ||Ax-b||_oo / ( eps * ( || x ||_oo * || A ||_oo + || b ||_oo ) * N )
- The relative machine precision (eps) is taken to be               1.110223e-16
- Computational tests pass if scaled residuals are less than                16.0
