A Coprocessor Sharing-Aware Scheduler for Xeon Phi-Based Compute Clusters

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 →

Snapify: capturing snapshots of offload applications on Xeon Phi manycore processors

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 →

Decaffeinated: experiencing the effects of caffeine by its abstinence

"I don't believe in caffeine!" I found myself repeating that sentence more than once, while hearing colleagues or friends talking and debating about the effects that caffeine has on them. It is said that caffeine gives addiction, that, in a moderate dosage, it can help the humor and increase the alertness; people drink coffee or … Continue reading Decaffeinated: experiencing the effects of caffeine by its abstinence →

The Gulf of Naples as seen from Princeton

I'm just back in Princeton, and I decided to share with you this picture taken few days ago during a walk in Naples (Napoli). I really enjoyed my stay at Home in Italy, having dinner with my family, visiting some relatives, going around in some amazing places, sharing few beers with friends of a lifetime … Continue reading The Gulf of Naples as seen from Princeton →

COSMIC: middleware for high performance and reliable multiprocessing on Xeon Phi coprocessors

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 →
