Gabriel WlazłowskiThis example describes step by step procedure that was executed in order to install the W-SLDA Toolkit on Eagle (PCCS) system.
- Step 1: Cloning the toolkit
- Step 2: Compiling supporting libraries and tools
- Step 3: Compiling ELPA
- Step 4: Setting templates for st codes
- Step 5: Setting templates for td codes
Step 1: Cloning the toolkit
git clone https://gitlab.fizyka.pw.edu.pl/wtools/wslda.gitStep 2: Compiling supporting libraries and tools
# On Eagle system compilation can be executed only via an interactive session
srun --pty -n 1 /bin/bash
# load compilers
module load openmpi/1.10.2-1_gcc482
# go to W-SLDA folder

See here for instructions.
Step 4: Setting templates for st codes
The same operations were applied to st-project-template and st-testcase-uniform folders. The following files were modified to the form as presented below.

## ------ QUEUE SYSTEM ------
## For submission use:
## sbatch job.sh
## For checking status use:
## squeue
## To kill job use:
## scancel pid

## ------ COMPUTATION -------
## For computation it is recomended to use location:
## cd ~/grant_518/scratch/
cd $SLURM_SUBMIT_DIR
source ./env.sh
## NOTE: YOU MUST ASSURE: -np=N*32 for altair
## -np=N*28 for standard
mpirun -np 56 ./st-wslda-2d input.txt
predefines.h
The job.sh script is configured to send the code to standard CPU nodes. Thus, one needs to set the correct drivers for ELPA.
#define DIAGONALIZATION_ROUTINE ELPA
// ...
/**
* uncomment it if you want to activate GPUs for diagonalizations
* */
// #define ELPA_USE_GPU
/**
* Select ELPA kernels,
* for more info see documentation of ELPA lib
* */
#define ELPA_USE_SOLVER ELPA_SOLVER_2STAGE
#define ELPA_USE_COMPLEX_KERNEL ELPA_2STAGE_COMPLEX_GENERIC
#define ELPA_USE_REAL_KERNEL ELPA_2STAGE_REAL_GENERICYou can always check the available ELPA kernel on your system by executing the tool elpa2_print_kernels.
Testing st codes
For testing, it is recommended to use st-testcase-uniform.
# Use scratch area for tests
