Subject: [OMPI users] Problem in using Linpack with open MPI when specifying the host file
From: Hameed Alzahrani (ibn_aibaan_at_[hidden])
Date: 2012-04-03 12:38:31


Hi,

I tried to benchmark a condor HPC cluster I installed open MPI on all the nodes (3 nodes) when I run mpi program and specifying the host file it works on all the nodes but when I tried to run the Linpack it does not work as expected (it takes most of the processor power but the memory still free and it does not shows the output even when I but small size of problem) but when I ran it without specifiyng the host it works fine. How can I benchmark the cluster using LINPACK?
Running

Running the MPItest program shows the response from each processor:

[condor_at_CM LinuxGeneric]$ mpirun -np 8 --hostfile hosts New
Process 5 on N1 out of 8
Process 6 on N2 out of 8
Process 4 on N1 out of 8
Process 7 on N2 out of 8
Process 0 on CM of 8
Process 3 on CM of 8
Process 1 on CM of 8
Process 2 on CM of 8

Running the LINPACK does not give any output:

[condor_at_CM LinuxGeneric]$ mpirun -np 8 --hostfile hosts xhpl

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 : 20
NB : 80 120
PMAP : Row-major process mapping
P : 1 2
Q : 8 4
PFACT : Left Crout Right
NBMIN : 2 4
NDIV : 2
RFACT : Left Crout Right
BCAST : 1ring
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
