This residency kicks off on May 6, 2013. The objective of this project is to highlight IBM Technical Computing Solutions as a flexible infrastructure for clients looking to reduce capital expenditure, reduce operational expenditures, energy optimization of resources, re-use the infrastructure, and get the most of their current and future hardware purchases to continue developing their business. Technical Computing is not just for High Performance Computing (HPC) clients, but for commercial clients who want to use the advantages of technical computing, for example, to analyze large quantity of data in their enterprise.
The residency team encourages you provide any comments on your opinion about IBM Technical Computing, any areas you might think can be studied during the residency, or any topic you would like to discuss with the team.
Keep an eye on this blog as the residency team continues to explore this area and the benefits IBM Technical Computing brings to the industry.

SAP HANA on IBM Power Systems helps to simply information technology (IT). The POWER8 server compliments the speed and agility of SAP HANA. The combination of these technologies helps to run large workloads, helps to run faster transactions, and helps to answer to the new customer demands. After all, you must be asking yourself: What else do you need in a great solution?
The combination of SAP HANA with IBM Power Systems simplifies the management of the technology, and together with Power Systems virtualization provide a flexible platform with high availability, capacity, and with high throughput: http://bit.ly/2qjYpHn.
The goal of the IBM Redbooks project is to develop an implementation guide for SAP HANA on Power Systems. This guide includes information on how to implement the solution, best practices, and incorporates high availability and disaster recovery. The guide combines theory and hands-on samples, illustrating scenarios discovered during field implementations.
The following example shows a global manufacturer Kennametal improving performance of their operations with IBM Power Systems and SAP HANA: http://bit.ly/2qL4zj7.

I am working brainstorming topics with my residency team about IBM PowerHA with focus on migration practices.
After evaluating the current documentation including: Installation guides (manuals) and available Redbooks, there is very good documentation on migration scenarios already available including combinations of operating systems and PowerHA versions.
I am asking the broader technical audience via my blog if there is anything outside of what is currently documented that you think might be useful to create content, and document it an IBM Redbooks.
Feedback would be greatly appreciate it.
I have a few question to help me influence and steer the residency team for the upcoming IBM PowerHA SystemMirror for AIX residency.
1. What are the challenging your customer face?
2. What are the gaps in technical content which can be developed during the residency?
3. Where can we make a big bang during this residency?
From a business perspective, field perspective? Your perspective! What is missing? gap?
Please let me know your comments so I can relay the message to the residency team.

PowerAI started off as a package of software distributions of many of the major deep learning software frameworks for model training like TensorFlow, Caffe, Torch, Theano, and the associated libraries like cuDNN. The PowerAI software has always been optimized for performance using the NVLink-based Power server, the IBM Power 822LC for HPC. The AI stack foundation starts with the right hardware: servers with accelerators and the right storage. GPU accelerators are extremely well suited for the compute-intensive nature of deep learning training, and servers with the highest CPU to GPU bandwidth, like IBM’s NVLink server, enable the high performance data transfer required for larger and more complex deep learning models. But all of this first starts with getting the right data.
IBM has announced a new set of PowerAI tools to make deep learning easier to use for data scientists. The four major additions are as follows:
AI Vision: A custom application development tool aimed at computer vision workloads. AI Vision enables application developers with little or no experience with deep learning to build a trained deep learning model for different input data sets.
Apache Spark-based Data Extraction, Transformation and Preparation tool: We enhanced IBM Spectrum Conductor with Spark (https://ibm.co/2s5xZwR) with a GUI-based set of tools that enable the data scientist to create functions that transform an input data set to the format required by frameworks like TensorFlow or Caffe, making it a cinch to match data sets to frameworks. For example, clients can have a transform function that resizes images for Caffe, and then simply transform and load any input data set into the right format to use with Caffe. IBM Spectrum Conductor with Spark automatically launches a whole set of Spark jobs on the cluster, each of which resizes a portion of the input data set.
DL Insight: Model tuning software that automatically tunes hyper-parameters for models based on input data sets using Spark-based distributed computing. We enhanced IBM Spectrum Conductor with Spark (https://ibm.co/2s5xZwR) so that it automatically launches multiple model training runs with different hyper-parameters using a subset of the data. It then monitors the training progress and searches and identifies the best hyper-parameters using several different search methods such as random and Bayesian search. To improve usability, DLInsight comes with a powerful and intuitive GUI that visualizes training and provides continuous feedback to quickly create and optimize deep learning models.
Distributed Deep Learning: To accelerate the training time, we are adding methods to scale a single training job across a cluster of servers. We have both a MPI-based scaling approach, inspired by high-performance computing methods, as well as a Spark and HPC converged distributed computing model, for clusters with either an Ethernet or InfiniBand network.

The IBM Redbooks Open DBaaS Implementation and Best Practices Guide residency (https://ibm.co/2rus6ch) has been announced and its goal is to create a technical enablement document describing IBM's scalable and reliable Cloud Database as a Service provisioning functionality for both relational and non-relational database engines. The goal of the residency project is to deliver a guide to educate users to quickly and easily utilize the features of a relational or non-relational database without the burden of handling complex administrative tasks. Moreover, the focus is to enhance the client experience by helping cloud users and database administrators to provision and manage multiple database instances as needed initially focusing on providing resource isolation at high performance while automating complex administrative tasks including deployment, configuration, patching, backups, restores, and monitoring. This integration document implements an Open Database as a Service environment for Linux on Power showing the ecosystem, open source tools, optimization guidelines, user management, monitoring, and so on.
For feedback on the upcoming Open DBaaS residency project, including ideas on what areas the publication should focus, kindly reply to this blog.
