The GMT offsets shown reflect the offsets at the moment of the conference.

Time Band

By setting a time band, the program will dim events that are outside this time window. This is useful for (virtual) conferences with a continuous program (with repeated sessions).
The time band will also limit the events that are included in the personal iCalendar subscription service.

Abstract

Array slicing is an operation which selects a subset of elements from a source array and copies them into a destination array. In this article we present an algorithm for generating code for a subset of Fortran slicing expressions, targeting the Intel Xeon Phi coprocessor. The resulting code outperforms the code produced by Intel’s Fortran compiler by 2.40X on average for a set of slicing expressions, and by 2.23X and 1.13X on average for two slicing expressions relevant for border exchange code.
