PDL CONSORTIUM SPEAKER SERIES
A ONE-AFTERNOON SERIES OF SPECIAL SDI TALKS BY
DATE: Thursday, May 10, 2012
SPEAKER: Brian Hirano, Corporate Architecture, Oracle
BIO: After twenty-four years, Oracle is still my first job after studying applied mathematics at MIT. I have spent most of my Oracle life working in Oracle RDBMS development working on the Virtual OS team. I've owned many components of the Oracle RDBMS, including locks (latches), memory management, and exception handling and designed or help to design various features up and down the Oracle RDBMS stack. While in RDBMS development, I also worked with hardware vendors and OS vendors in the areas of Oracle performance and specifying future hardware and OS features beneficial to Oracle features and performance. I am currently deciding what to do next at Oracle, but I remain involved in design discussions on hardware and software interactions with developers from the Oracle database product teams, Java development, and Linux development.
SPEAKER: Nisha Talagala, Fusion-io
This talk covers the implications of nonvolatile memory on software. We describe the stresses that non volatile memory places on existing application and OS designs, and illustrate optimizations to exploit flash as a new memory tier. Until the introduction of flash, there has been no compelling reason to change the existing operating system storage stack. We will describe the technologies contained in the upcoming Fusion-io Software Developer Kit (ioMemory SDK) that allow applications to leverage the native capabilities of non-volatile memory as both an I/O device and a memory device. The technologies described will include new I/O based APIs and libraries to leverage the ioMemory Virtual Storage Layer, as well as features for extending DRAM into flash for cost and power reduction. Finally, we describe Auto-Commit-Memory, a new persistent memory type that will allow applications to combine the benefits of persistence with programming semantics and performance levels normally associated with DRAM.

BIO: Nisha Talagala is Lead Architect at Fusion-io, where she works on innovation in non volatile memory technologies and applications. Nisha has more than 10 years of expertise in software development, distributed systems, storage, I/O solutions, and non-volatile memory. She has worked as technology lead for server flash at Intel - where she led server platform non volatile memory technology development and partnerships. Prior to Intel, Nisha was the CTO of Gear6, where she developed clustered computing caches for high performance I/O environments. Nisha also served at Sun Microsystems, where she developed storage and I/O solutions and worked on file systems. Nisha earned her PhD at UC Berkeley where she did research on clusters and distributed storage. Nisha hold more than 30 patents in distributed systems, networking, storage, performance and non-volatile memory.
SPEAKER: James Nunez, Los Alamos National Lab
BIO: James is currently a member of the Ultrascale Systems Research Center at Los Alamos National Lab exploring I/O, file systems and storage for exascale systems and beyond. As part of the High Performance Systems Intergration Group, James has been involved with the ASC File System Path Forward effort to create a high scalable global parallel file system based on secure object device technology, organized the High End Computing File Systems and I/O Workshop for seferal years, and concerned with evaluating and benchmarking HPC file systems, I/O middleware solutions, and understanding the I/O interface and application of new storage innovations to real science applications. James was awarded a Master of Science in Computer Science in 1998 and a Master of Science in Mathematics in 1996 from the University of Michigan, Ann Arbor, and a Bachelor of Science in Mathematics in 1994 from the University of California, Irvine.
SPEAKER: Wojciech Golab, HP Labs
SPEAKER: Tom Ambrose, Emulex
BIO: Tom Ambrose is the Sr. Director of Engineering, Systems/Technology/Architecture at Emulex Corporation. He has a B.S. ECE from Carnegie Mellon and 15+ years in ASIC design/management. He has been working for 5 years in his current Architecture role.
SPEAKER: Jiri Schindler, NetApp
This talk will reflect on the evolution of flash memory in enterprise storage systems from the prospective of an enterprise storage vendor. It will outline the design rationale behind alread-released products with SSDs and PCI-attached I/O accelerators in a centrally managed dedicated storage system. Most of it will focus on exploratory work in combining host-side (client) Flash deployments with the benefits of centrally-managed storage system. [SLIDES - PDF]
BIO: Jiri Schindler is a member of technical staff in the NetApp's Advanced Technology Group. For the last three years he has been working on new storage systems architectures that combine flash memory and hard disk drives (HDD): his previous work proposed the use of flash memory to achieve suitable data allocation strategy for efficient execution of workloads dominated by small logical updates followed by large serial reads. Jiri is a Carnegie Mellon alum (he was the first PhD student of Prof. Greg Ganger).
