Hi,
I have installed intel2020u0 on RHEL 7.6 based system having intel 8280M processor.
While running a quick test with linpack binary provided under compilers_and_libraries_2020.0.166/linux/mkl/benchmarks/mp_linpack , i end up with issues. Here is how i setup and run the linpack binary (on single node) -
[user@node1 BASELINE]$ cp /home/user/COMPILER/MPI/INTELMPI/2020u0/compilers_and_libraries_2020.0.166/linux/mkl/benchmarks/mp_linpack/xhpl_intel64_static /home/user/COMPILER/MPI/INTELMPI/2020u0/compilers_and_libraries_2020.0.166/linux/mkl/benchmarks/mp_linpack/runme_intel64_static /home/user/COMPILER/MPI/INTELMPI/2020u0/compilers_and_libraries_2020.0.166/linux/mkl/benchmarks/mp_linpack/runme_intel64_prv /home/user/COMPILER/MPI/INTELMPI/2020u0/compilers_and_libraries_2020.0.166/linux/mkl/benchmarks/mp_linpack/HPL.dat .

[user@node1 BASELINE]$ ls HPL.dat runme_intel64_prv runme_intel64_static xhpl_intel64_static [user@node1 BASELINE]$ ./runme_intel64_static This is a SAMPLE run script.

now, in the 2020u0 environment, if i remove the xhpl_intel64_static binary and use the one supplied with 2019u5 (HPL 2.3), HPL works fine -
[user@node1 BASELINE]$ cp /home/user/COMPILER/MPI/INTELMPI/2019_U5/compilers_and_libraries_2019.5.281/linux/mkl/benchmarks/mp_linpack/xhpl_intel64_static .
[user@node1 BASELINE]$ ./runme_intel64_static
This is a SAMPLE run script. Change it to reflect the correct number
of CPUs/threads, number of nodes, MPI processes per node, etc..

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 : 1000
NB : 192
PMAP : Column-major process mapping
P : 1
Q : 1
PFACT : Right
NBMIN : 2
NDIV : 2
RFACT : Crout
BCAST : 1ring

SWAP : Binary-exchange
L1 : no-transposed form

- 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
