|Description||We are carrying out rapid, patient specific simulations of bloodflow in intracranial cerebral aneurysms to assess the short and long range effects of their treatment via the introduction of a stent or flow diverter. The simulations are to be executed over a full range of physiological states to inform clinicians about the long term consequences of their choice of treatment.|
|Computational requirements||Programming language: C++
Dependencies: cmake, parmetis, tinyXML, boost, MPI, ctemplate, cppunit.
Memory requirements:1-2G per rank depending on sparsity and problem size.
Disk requirements: HDF5 is required for some features.
|Type of software licence||Open.|
|Input requirements||Format: STL (for surface geometry), XML (config file), GMY (HemeLB own format)
Coming from:The XML and GMY are generated from the STL using the HemeLB setup tool.
Disk use: GMY is the only large file, and it is typically 100M to 2G in size.
|Output requirements||Format: Own format, XTR.
Used by: Paraview.
Disk use: Depends on geometry size/output frequency. Can be between 500Mb and 20G.
|Performance and HPC profile|
|Parallelism||Type of parallelism: MPI.
Scalability: Typical runs 7200 cores / 300 nodes. Large runs 60000 cores / 2500 nodes.
|Mode of operation||One single extreme parallel run for each problem required.|
|Deployed on||LRZ SuperMUC, Prometheus (PLGrid), Eagle (PLGrid), Inula (PLGrid), ARCHER (EPCC).|
