Benchmark AmpereOne A192-32X

[geerlingguy]

I have a system Ampere / Supermicro sent over for testing, it's the 192-core CPU, with 512 GB of DDR5 RAM at 5200 MT/s.

See: geerlingguy/sbc-reviews#52

CPU was self-reporting 297W power draw, I don't have my wall power measurement set up yet, but will soon. The power strip showed 8A at 120V (for the full rack), so somewhere between 500-600W for the full system probably.

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      :  203788
NB     :     256
PMAP   : Row-major process mapping
P      :       1
Q      :     192
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

That score would put this system at rank #460 on the 2006/06 Top500 List (see https://hpl-calculator.sourceforge.net/hpl-calculations.php and https://www.top500.org/lists/top500/list/2006/06/?page=5).

It about matches the Saguaro cluster at Arizona State University, which consumed around 80 kilowatts of power in 2006.
