I have been sent an ADLINK Ampere Altra Dev Kit with a Q64-22 CPU for testing.
I've installed 96 GB of Samsung DDR4 3200 ECC RAM, and would like to see how it compares to some of its beefier bretheren (see #10 and #17).
Some interesting notes/observations are documented on the unofficial Ampere Altra Dev Kit wiki.

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 : 87236
NB : 256
PMAP : Row-major process mapping
P : 8
Q : 8
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

Also going to try with Ampere's optimized config: https://github.com/AmpereComputing/HPL-on-Ampere-Altra

Optimized version, 655.9 Gflops, at about 140W again. So 4.685 Gflops/W
