Comments on HPL (High Performance Linpack): Benchmarking Raspberry PIs
Benchmarking is the process of running some of the standard programs to evaluate the speed achieved by a system. There are a number of standard bechmarking programs and in this tutorial we benchmark the Linux system using a well known program called the HPL, also known as High Performance Linpack.

I followed your instructions; uset your HPL.dat file;;i am getting following error:HPL ERROR from process # 0, on line 355 of function HPL_pdinfo:>>> Number of values of NB is less than 1 or greater than 20 <<<HPL ERROR from process # 0, on line 621 of function HPL_pdinfo:>>> Illegal input in file HPL.dat.

I have been following your instruction and I am stuck on the 4th step. I have no bin/rpi and makeh gives me "command not found". Please help me if you can. My grade depends on this working.
Background: cluster of 4 RPI 2 Bs, trying to benchmark them with Linpack before I move on to my own testing. I should have all the required software installed
I installed libmpich2-dev and I get the error "gfortran: error: /usr/local/mpich2/lib/libmpich.a: No such file or directory" when execute make arch=rpi command. ¿What's wrong?
Thank you so much for the info. It was very usefull to me. I am a Bachelors student from Spain and I started a project from this manual.
PS: to Lanze, step 4 is a mistake. Just try "make arch=rpi".
Hello sir, do you have link or tutorial how to install mpich2, because i have followed your step and not found in my directory
/usr/local/mpich2 and i am stuck in step 3.
A better, easier way to install and run linpack bench on the pi (pi3). Be sure to reboot after install and before running.
sudo apt-get install libmpich-dev wget http://web.eece.maine.edu/~vweaver/junk/pi3_hpl.tar.gz tar -xvzf pi3_hpl.tar.gz chmod +x xhpl run: ./xhplStock Pi 3 6.1 Gflops

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 : 8000
NB : 256
PMAP : Row-major process mapping
P : 1
Q : 1
PFACT : Left
NBMIN : 2
NDIV : 2
RFACT : Right
BCAST : 2ring
DEPTH : 0
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

Is there a formatting issue? (I didn't post it the way it is shown above), here is the raspberry pi linpack instructions again:
sudo apt-get install libmpich-dev
wget http://web.eece.maine.edu/~vweaver/junk/pi3_hpl.tar.gz
tar -xvzf pi3_hpl.tar.gz
chmod +x xhpl

Hi, i am in step 4, when i execute make arch=rpi
the file starts executing but stops with the following error

you need to modify TOPdir.
if you untar hpl in Downloads then
TOPdir = $(HOME)/Downloads/hpl
mpirun was unable to launch the specified application as it could not access
or execute an executable:
Executable: ./xhpl
Node: 0d6d82c2706c
while attempting to start process rank 0.
For those who have problems compiling it here is my Makefile.rpi. I used hpl-2.2. and mpich3.
It uses different paths and additional compile flags to compile successfully. Tested on Rpi 3 model B. The resulting xhpl executable is located under ~/hpl-2.2/bin/UNKNOWN. Using the HPL.dat from the article gave me the next result:

Hi all,
Is it possible to run the same HPL.dat file for single node and the GFlops to be 1.302e+00???? instead of MFlops???
what am I doing wrong??
