Proceedings of the ACM SIGCOMM 2010 conference, 2010
The basic building block of ever larger data centers has shifted from a rack to a modular container with hundreds or even thousands of servers. Delivering scalable bandwidth among such containers is a challenge. A number of recent efforts promise full bisection bandwidth between all servers, though with significant cost, complexity, and power ...

Helios is a distributed, highly-scalable system used at Microsoft for flexible ingestion, indexing, and aggregation of large streams of real-time data that is designed to plug into relational engines. The system collects close to a quadrillion events indexing approximately 16 trillion search keys per day from hundreds of thousands of machines across ...

<span>Este elemento, que se genera en las estrellas, es el segundo más abundante en el Universo después del hidrógeno y constituye el 7% de la materia total en él. En cambio, en la Tierra es tan escaso, que ni siquiera fue descubierto aquí y es el único elemento que se descubrió fuera de ella.

Proceedings of the ACM SIGOPS 22nd symposium on Operating systems principles, 2009
Helios is an operating system designed to simplify the task of writing, deploying, and tuning applications for heterogeneous platforms. Helios introduces satellite kernels, which export a single, uniform set of OS abstractions across CPUs of disparate architectures and performance characteristics.

Helio-hydro and helio-thermal production of hydrogen
International Journal of Hydrogen Energy, 2003Fossil fuels account for about 80% of the world annual energy demands. Renewables contribute 14% and nuclear some 6%. These numbers will soon change as the world's population grows, energy demand rises, cheap oil and gas deplete, global warming effects continue rising and city pollution worsens the living conditions.
