Right after the kickboxing class, I saw one of classmate and friend of mine trying to solve a physics exercise. I studied physics in high school, and I had a exam in college; it was long time ago and even at that time I wasn't very strong in the matter (and I used to soothe … Continue reading Physics for martial arts students
"... mi ritrovai per una selva oscura, ché la diritta via era smarrita ..." (Divina Commedia - Canto I) Like Dante in his allegoric journey, I (also) "found myself deep in a darkened forest, for I had lost all trace of the straight path" in the computing world. The "darkened forest" in which I found … Continue reading First step of my journey for rediscovering the straight path (aka I’m using again GNU Emacs after many years)
In Parallel and Distributed Processing Symposium, 2014 IEEE 28th International We propose a cluster scheduling technique for compute clusters with Xeon Phi coprocessors. Even though the Xeon Phi runs Linux which allows multiprocessing, cluster schedulers generally do not allow jobs to share coprocessors because sharing can cause oversubscription of coprocessor memory and thread resources. It … Continue reading A Coprocessor Sharing-Aware Scheduler for Xeon Phi-Based Compute Clusters
In Proceedings of the 23nd international symposium on High-performance parallel and distributed computing (HPDC ’14). ACM, New York, NY, USA, 1-12. Intel Xeon Phi coprocessors provide excellent performance acceleration for highly parallel applications and have been deployed in several top-ranking supercomputers. One popular approach of programming the Xeon Phi is the offload model, where parallel … Continue reading Snapify: capturing snapshots of offload applications on Xeon Phi manycore processors
In Proceedings of the 22nd international symposium on High-performance parallel and distributed computing (HPDC ’13). ACM, New York, NY, USA, 215-226. It is remarkably easy to offload processing to Intel’s newest manycore coprocessor, the Xeon Phi: it supports a popular ISA (x86-based), a popular OS (Linux) and a popular programming model (OpenMP). Easy portability is … Continue reading COSMIC: middleware for high performance and reliable multiprocessing on Xeon Phi coprocessors
It is one year since my last post. I don't have too much to tell, I wanted just to mark time.
