“…We implement the software running on the compute cluster with an emphasis on modularity, allowing for flexible adjustment of the infrastructure and a good scalability with respect to the number of network interfaces, available CPU cores, and deployed machines. By using a modular design we are able to not only employ CPU-based fitting algorithms, but also have the possibility to take advantage of the performance offered by a GPU-based approach to fitting.…”

“…We have also simulated wave conduction in the three-dimensional (3D) anatomic heart with GPUs where we found the computational speed with a single GPU is 1.6 times slower than with a 32-central processing unit (CPU) Opteron cluster. However, a cluster with two or four GPUs is faster than the CPU-based cluster. …”

“…Regression tests are required to be performed by the Geant4 team within a short period of time (2 to 3 weeks), basically demanding vast computational resources (equivalent to approximately 4 CPU years). In order to cope with this abrupt rise in CPU power, EGEE Grid resources are utilized (several EGEE sites provide resources for these Geant4 production series). …”

“…METHODOLOGY/PRINCIPAL FINDINGS: Our algorithm, named Murasaki, makes it possible to identify anchors within multiple large sequences on the scale of several hundred megabases in few minutes using a single CPU. Two advanced features of Murasaki are (1) adaptive hash function generation, which enables efficient use of arbitrary mismatch patterns (spaced seeds) and therefore the comparison of multiple mammalian genomes in a practical amount of computation time, and (2) parallelizable execution that decreases the required wall-clock and CPU times. …”
