Hello everyone,

I’m struggling to run the CUDA accelerated Linpack benchmark on my university’s cluster. I got the benchmark from here: https://developer.nvidia.com/rdp/assets/cuda-accelerated-linpack-linux64

Building it seems to work, I do not get any errors there. But when I try to run the benchmark with

```
mpirun -np 4 ./run_linpack
```

I get the following output and error:

```

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 : 25000
NB : 768
PMAP : Row-major process mapping
P : 2
Q : 2
PFACT : Left
NBMIN : 2
NDIV : 2
RFACT : Left
BCAST : 1ring
DEPTH : 1
SWAP : Spread-roll (long)
L1 : no-transposed form
U : no-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

```

There seems to be some problem with the OPENBLAS library (**undefined symbol: dtrsm**). I was unsuccessfull to fix that and couldn’t find any help online yet. I hope someone here has an idea what I should do/try next.

If you need more information to assist me I will gladly provide them.

Kind regards
