MQTT: MQ Telemetry Transport. It is a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks
MQTT is a machine-to-machine (M2M)/”Internet of Things” connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium. For example, it has been used in sensors communicating to a broker via satellite link, over occasional dial-up connections with healthcare providers, and in a range of home automation and small device scenarios. It is also ideal for mobile applications because of its small size, low power usage, minimised data packets, and efficient distribution of information to one or many receivers
Mantissa Corporation: 32bit Intel on IBM mainframe
Q. What level of hardware is required for x86VM? A. An IBM System zEnterprise class server. At minimum a z114 or z196 or higher level. Q. What operating systems can I run on z86VM? A. At this point, only Linux has been successfully tested. We’re working to enable additional systems. Q. When will Windows be certified? A. That’s a two step process. First we have to complete our own testing. Then we need to submit our test results to Microsoft for review. We hope that will be quick. When that Beta is ready, customer experience will help. Q. When will 64 bit support be completed? A. We believe there is sufficient function and performance in our 32 bit capabilities. We’ll see how well that is accepted before we make any commitment to 64 bit.

On DB2 and Table-Pinning by Robert Catterall
In some non-DB2 DBMS environments, a table that is to be pinned in memory must be explicitly marked as such. With DB2, this is not the case.
How do I pin a DB2 table in memory? Easy – I just assign it to a buffer pool that has enough buffers to hold all the table’s pages. Here’s a very simple example: I have a DB2 table, called XYZ, that occupies 1000 4K pages (the page size doesn’t matter – could be 4K pages, 8K, 16K, whatever). I want to pin this table in memory. I set up buffer pool BP8 (the actual buffer pool name doesn’t matter) with 1000 4K buffers.
Dongarra+Hinds: Unrolling Loops in FORTRAN
The technique of ‘unrolling’ to improve the performance of short program loops withoutresorting to assembly language coding is discussed. A comparison of the benefits of loop
‘unrolling‘ on a variety of computers using an assortment of FORTRAN compilers is
KEY WORDS Unrolled loops FORTRAN Loop efficiency Loop doubling
It is frequently observed that the bulk of the central processor time for a program is
localized in 3 per cent of the source code.6 Often the critical code from the timing perspective
consists of one (or a few) short inner loops typified, for instance, by the scalar product of
two vectors. A simple technique for the optimization of such loops, with consequent
improvement in overall execution time, should then be most welcome. ‘Loop unrolling’ (a
generalization of ‘loop d~ubling’),~ applied selectively to time-consuming loops, is just
such a technique.
TmaxSoft provides a full range of advanced enterprise system software to industry leaders throughout the world. TmaxSoft’s legacy modernization software products provide IT integrity, reliability, expandability and cost reduction to over 1,400 leading organizations throughout the world, including clients within the US, Korea, Japan and China.
TmaxSoft specializes in legacy system modernization and provides two comprehensive paths for enterprises: mainframe rehosting and implementing SOA-based total enterprise systems. Our powerful OpenFrame rehosting software has been used worldwide to migrate mission-critical IT systems from mainframe-based environments to more flexible and cost-efficient open system environments. In April of 2006, TmaxSoft completed rehosting the system of Samsung Life Insurance, a major life insurance provider. At the time, this was the largest rehosting project ever undertaken (7,500 MIPS). Our ProFrame application framework and associated products have been
Dell guns for IBM mainframes with Clerity gobble
Clerity says it has over 1,300 sites worldwide using its migration and rehosting tools today. At the time Sun bought the UniKix business from Critical Path more than a decade ago, that business had 300 customers with 900 installations and Sun was expecting to do around 50 mainframe replacements a year and generate maybe $100m in hardware, software, and services revenues a year. Sun boosted the UniKix installed base to 1,400 sites by the time it sold it to Clerity in 2006.
Clerity to Revive Mainframe Rehosting after Acquiring Sun Tools
Clerity Solutions has a 15-year history of providing porting services and tools from obscure computing systems to more modern computers. But by acquiring a set of mainframe application porting and rehosting tools from Sun Microsystems, which the company quietly did at the end of June, Clerity is now a relatively big player at many mainframe shops.
Clerity, which is based in the Chicago suburb of Oakbrook Terrace, has been doing ports of old Wang word processing systems and HP 3000 MPE-based minicomputers to other platforms, and had approximately 25 employees before buying Sun’s Mainframe Transaction Processing (MTP) and Mainframe Batch Manager (MBM) systems software and middleware for an undisclosed sum. The MTP software is, in essence, a clone of IBM’s CICS transaction monitor and COBOL environment for mainframes, and MBM is a set of software that can mimic the Job Control Language of a mainframe that runs batch jobs. Clerity has acquired all of the intellectual property associated
