The latest innovations in multicore technology are meaningless if the software you run is not written to take advantage of the advanced hardware design. To help address this and other issues, attendees at the Second Barcelona Multicore Workshop (BMW) met October 21-22, 2010, to critically examine developments in computer chip technology in the two years since the highly successful 2008 workshop.
Today, sequential chips are almost entirely superseded by multicore processors. The hardware community is focused on designing these processors to maximize the potential performance. Meanwhile, software developers need to know how best to program for machines that use this multicore technology, particularly when it is used for desktop workloads or on mobile devices rather than traditional scientific applications.
To help understand and solve these concerns in a multidisciplinary manner, representatives from Barcelona Supercomputing Center, Hipeac, Microsoft Research, and academics and researchers from Europe, Asia, and the United States met and cross-fertilized ideas across the hardware and software communities. Many participants report that the conference sparked new plans for collaboration, including company partnerships with academia and the sharing of valuable tools and ideas.
Among the key discussions were:
