[QE-users] Unexpected KNL MCDRAM cache size 269156352, Unexpected KNL MCDRAM cache size 269156352, Abort(1) on node 35 (rank 35 in comm 0): application called MPI_Abort(MPI_COMM_WORLD, 1) - process 35

[Gürcan Serttaş]

Hello,

We have Intel(R) Xeon Phi(TM) CPU 7210 @ 1.30GHz processor and we want 
to run quantum espresso 6.5 with
Intel(R) MPI Library for Linux* OS, Version 2019 Update 8.  We are using 
Slurm Workload Manager and when we want to submit a job in three nodes 
and using 192 cores (64x3 ), we encountered the following error. We 
cannot run a job more than 64 cores in three codes.

-Cluster mode Quadrant - Memory Mode Flat

#mpirun -np 192 numactl -m 1  /apps/q-e-qe-6.5/bin/pw.x <test.in> test.out

*Unexpected KNL MCDRAM cache size 269156352**
**Unexpected KNL MCDRAM cache size 269156352**
**Abort(1) on node 35 (rank 35 in comm 0): application called 
MPI_Abort(MPI_COMM_WORLD, 1) - process 35*

-Cluster mode Quadrant - Memory Mode Cache

*Abort(1) on node 35 (rank 35 in comm 0): application called 
MPI_Abort(MPI_COMM_WORLD, 1) - process
*

How do we compile properly the quantum espresso 6.5 according to Xeon 
Phi(TM) CPU 7210 processor and How we change BIOS setting in regarding 
with  Intel® Xeon Phi™ processors code-named Knights Landing (KNL).

Could you please help us in this problem?

Kind Regards.
