Alya is a simulation code for high performance computational mechanics. Alya solves coupled multiphysics problems using high performance computing techniques for distributed and shared memory supercomputers, together with vectorization and optimization at the node level.
This kernel corresponds to the algebraic system assembly of a finite element code (FE) for solving partial differential equations (PDE’s). The matrix assembly consists of a loop over the elements to compute element matrices and right-hand sides and their assemblies in the local system.
There are two available versions of this kernel:
The kernel requires at least gfortran 10.1.0 to be built.
#> export OMP_NUM_THREADS=4 (or whatever you want) #> ./miniapp.x
If everything goes fine, you should see something like that:
start read VECTOR_SIZE read= 16 ifdef read= NO_COLORING element chunks= 300 end read Number of subdomains= 1 Assembly Execution Time = 2.008 seconds. loop finished correctly
