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
"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

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
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
CRUX PPC 3.0 is now available. Toolchain ships with Graphite support (PPL backend) and also with LTO (Link Time Optimization). CRUX PPC 3.0 is released as two different archives: 32bit and 64bit. The 32bit version is based on a single lib toolchain instead the 64bit one comes with a multilib toolchain. These two versions share … Continue reading CRUX PPC 3.0 released!
