Benchmark Milk-V Mars CM - JH7110 4x 1.5 GHz RISC-V

As the title says... I can't get ansible running locally on the device since cryptography won't install, and I had trouble upgrading pip. So I'll run it from my Mac over SSH.

Hmm, MPICH compile fails:

    hostinfo               =
    /bin/universe          =
    /usr/bin/arch -k       =
    /bin/arch              =
    /usr/bin/oslevel       =
    /usr/convex/getsysinfo =
  
    UNAME_MACHINE = riscv64
    UNAME_RELEASE = 5.15.0
    UNAME_SYSTEM  = Linux
    UNAME_VERSION = #9 SMP Sun Oct 8 17:14:43 CST 2023
    configure: error: cannot guess build type; you must specify one

Maybe mpich 4.1.2 will work? (Using 3.1.2 currently).

Looks like it! Compiling now...

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      :   14745
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

Need to measure power consumption next.
