Benchmark Sipeed Lichee Console 4A #29

Closed geerlingguy closed 7 months ago

geerlingguy commented 7 months ago

I would like to see how the Lichee Console 4A runs; it uses the 4-core TH1520 SoC, underclocked to 1.5 GHz. See related: https://github.com/geerlingguy/sbc-reviews/issues/39

If trying to install Ansible locally, to run the playbook on the device itself, I run into:

            building '_cffi_backend' extension

So I'll have to run it from outside.

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      :   34581
NB     :     256
PMAP   : Row-major process mapping
P      :       1

- 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

I don't have power metrics. I'll run it again on the test bench later and get that.

geerlingguy commented 7 months ago

To get a power reading, I plugged in the wall charger and charged the device for a few hours until the power reading was under 1W (meaning the battery was fully charged):

Then I re-ran the benchmark a couple times, measuring power consumption:

Here is the final result:
