Presentation

YALES2BIO is a red blood flow solver. It is used for the analysis of medical devices in contact with blood such as flow diverters, Ventricular Assist Devices, extra corporal circulation, artificial heart and valves, cytometers among others. Optimizing such devices requires dealing with both macroscopic (pressure loss, residence time, wall shear stress, turbulence) and microscopic (blood cells deformation and interaction with other cells or solid boundaries) features.

Technical information:

• website : https://imag.umontpellier.fr/~yales2bio/index.html
• Scientific domain : haemodynamics
• Language : Fortran
• Parallelism : MPI + OpenMP
• GPU acceleration : No
• Scalability : good
• Vectorization: poor

Compilation and simulation:

Here we describe the different phases from the download to the validation of the simulation.

Download:

The sources are available in a tarball and correspond to a stable release. To un-tar this release, run

export TARBALL_PATH=path/to/yales2bio-devel/tarball (on occigen TARBALL_PATH=$SCRATCHDIR/abs_porject/)
./download.sh

The path of the tarball is given by the environement variable TARBALL_PATH, exported in the .

Compile:

To compile the code, several librairies are needed:

• hdf5 in sequential (works with the 1.8.17 version)
• parmetis
• scotch

Then, a Makefile.in is needed. For IRENE, OCCIGEN and JEAN-ZAY platforms, this file is already made. For another platform one has to write it. An example can be found in...

Compile the code using:

source machines/occigen-bdw/env
./compile.sh

machines/occigen-bdw/env contains the information for compilation (module load gcc openmpi lapack hdf5 ...)

Run and validate the simulation:

For each test case, given in a separate folder (e.g. testcase_small), you can find three scripts:
