Running it from my Mac instead of local, because installing Ansible on RISC-V is annoying (but not impossible), and also running with a newer version of mpich because it seems the 4.1.2 version won't compile for some reason...

[geerlingguy]

It breaks specifically here:

$ ./configure --with-device=ch3:sock FFLAGS=-fallow-argument-mismatch
...
checking whether routines compiled with -O2 can be linked with ones compiled without -O2... yes
checking for shared library (esp. rpath) characteristics of CC... done (results in src/env/cc_shlib.conf)
configure: error: No Fortran compiler found. If you don't need to
        build any Fortran programs, you can disable Fortran support using
        --disable-fortran. If you do want to build Fortran
        programs, you need to install a Fortran compiler such as gfortran
        or ifort before you can proceed.

I was attempting to run this on WSL, and I managed to solve the issue by installing gfortran-10 with apt, then changing line 56 in main.yml to - ./configure --with-device=ch3:sock FFLAGS=-fallow-argument-mismatch FC=gfortran-10. Hopefully this helps someone else out there!

I ran sudo apt install -y gfortran, which installed gofrtran-13, and then tried again. Also had to manually install git, then it ran all the way through:

================================================================================

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      :       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
