The Big Data of Holistic Performance Analysis

Mar 19, 2014 |

Without the possibility of revolutionary new shifts in large-scale computing on the hardware horizon, an increasing amount of attention is being turned to various modes of optimization. These efforts extend beyond tweaking codes for HPC systems into the realm of using detailed, holistic performance data to maximize performance and efficiency across existing architectures. According to Read more…

Is the ECC Performance Price Worth it for GPUs?

Mar 13, 2014 |

Listen to the podcast followup on this story. One of several elements that separates high performance computing GPUs from their gaming and graphics brethren is the addition of ECC codes, which target critical bit-flip errors in memory, which can lead to invalid results or system problems. While ECC is often deemed a necessary component for Read more…

Benchmarking MPI Communication on Phi-Based Clusters

Mar 12, 2014 |

Intel’s Many Integrated Core (MIC) architecture was designed to accommodate highly-parallel applications, a great many of which rely on the Message Passing Interface (MPI) standard. Applications deployed on Intel Xeon Phi coprocessors may use offload programming, an approach similar to the CUDA framework for general purpose GPU (GPGPU) computing, in which the CPU-based application is Read more…

Centaurus Energy Donates IBM Supercomputer to NSU

Mar 5, 2014 |

Centaurus Energy has donated an IBM supercomputer nicknamed “Megalodon” to Nova Southeastern University. Megalodon is an IBM P6 supercomputing cluster composed of 32 nodes that each have 16 POWER CPU’s with 256 GB of RAM. Each CPU contains two processor units and has about 790 million transistors as well. Megalodon is also water-cooled and uses Read more…

Supercomputers Advance Understanding of Black Holes

Mar 3, 2014 |

Black holes, so fascinating to star-gazers of the professional and backyard variety, are definitely not empty as their name might imply. Quite to the contrary, they are exceedingly dense. According to NASA, these astronomic objects comprise a great amount of matter packed into a very small zone. It’s like a star ten times more massive Read more…
