The time_t type in 32-bit Linux overflows in January 2038, which breaks all existing application binaries. We'll talk about how we are addressing this in the kernel, in glibc and in distributions, what problem are still unsolved, and the various ways in which even 64-bit systems are still affected.

With the exponential rise in quantity of data to manage, the modern data centre is increasingly limited by the capacity of individual machines. Since storage and compute demand more capacity than can be provided by a single machine, we distribute both over large clusters and use the network to transfer data between where it is stored and where it is processed. Moving all that data around uses deep storage stacks which incur a significant performance impact. If we could somehow flatten the storage stack and provide applications with direct access to data, then we could improve performance by orders of magnitude. Hewlett Packard Enterprise recently demonstrated that we can do exactly with their research project, ""The Machine"". Instead of moving data around with a network, The Machine uses multi terabytes of persistent memory and a next generation fabric-attached memory interconnect to provide a single pool of storage which can be accessed by any processor in the cluster. It shows that we can provide applications with immediate load/store access to huge data sets in a model called Memory-Driven Computing. Proof in hand, now it is time to bring Memory-Defined Computing to the data centre. Gen-Z is an open systems interconnect designed to provide memory semantic access to data and devices via direct attached, switched or fabric topologies. HPE has joined the Gen-Z consortium and is using the knowledge gained with The Machine to help shape Gen-Z to set the stage for true Memory-Driven Computing. With putting memory at the centre, this enables us to overcome the limitations of today's computing systems and power innovations. This session will cover two topics. It will start with a status update on The Machine and an overview of how it works. Then we'll shift into an introduction of Gen-Z, and how it can reshape the architecture of computing in the years to come.

This session will cover new features and additions to QEMU that happened over the last year, ranging from new features for KVM support to Multi-Threaded TCG (MTTCG) and QEMU linux-user improvements. We will also discuss upcoming work to support LITE and IoT development and hope for a healthy discussion on requirements for members interested in these areas.
