Best bang for your buck: GPU nodes for GROMACS biomolecular simulations

The molecular dynamics simulation package GROMACS runs efficiently on a wide variety of hardware from commodity workstations to high performance computing clusters. Hardware features are well exploited with a combination of SIMD, multi-threading, and MPI-based SPMD/MPMD parallelism, while GPUs can be used as accelerators to compute interactions offloaded from the CPU. Here we evaluate which […]

Mega-KV: A Case for GPUs to Maximize the Throughput of In-Memory Key-Value Stores

In-memory key-value stores play a critical role in data processing to provide high throughput and low latency data accesses. In-memory key-value stores have several unique properties that include (1) data intensive operations demanding high memory bandwidth for fast data accesses, (2) high data parallelism and simple computing operations demanding many slim parallel computing units, and […]

High Performance Approximate Sort Algorithm Using GPUs

Sorting is a fundamental problem in computer science, and the strict sorting usually means a strict order with ascending or descending. However, some applications in reality don’t require the strict ascending or descending order and the approximate ascending or descending order just meets the requirement. Graphics processing units (GPUs) have become accelerators for parallel computing. […]

Modelling the Formation of Ordered Acentrosomal Microtubule Arrays

Acentrosomal microtubules are not bound to a microtubule organising centre yet are still able to form ordered arrays. Two clear examples of this behaviour are the acentrosomal apico-basal (side wall) array in epithelial cells and the parallel organisation of plant cortical microtubules. This research investigates their formation through mathematical modelling and Monte Carlo simulations with […]

Texture Cache Approximation on GPUs

We present texture cache approximation as a method for using existing hardware on GPUs to eliminate costly global memory accesses. We develop a technique for using a GPU’s texture fetch units to generate approximate values, and argue that this technique is applicable to a wide variety of GPU kernels. Applying texture cache approximation to an […]

GPU phase-field lattice Boltzmann simulations of growth and motion of a binary alloy dendrite

A GPU code has been developed for a phase-field lattice Boltzmann (PFLB) method, which can simulate the dendritic growth with motion of solids in a dilute binary alloy melt. The GPU accelerated PFLB method has been implemented using CUDA C. The equiaxed dendritic growth in a shear flow and settling condition have been simulated by […]
