Intel's Developer Forum kicks off today, and the show will include a host of news for developers, highlighted by the update of Intel Parallel Studio XE to version 2013. The new version includes debugging support for Java and more reliable floating-point processes. Additionally, Intel announced that it would be consolidating its many developer networks into a single cohesive network.
Christos Georgiopoulos, vice president of the Software and Services Group and general manager of Developer Relations Division at Intel, said that the newly named Intel Developer Zone will include all of the content, educational materials and software that had previously been available across Intel's many different developer sites.
Specifically, he said, Intel Developer Zone will offer help for developers building software on multiple platforms, working with multi-threaded applications, or working on HTML5.
“We're also launching an HTML5 initiative, with tools capabilities and all kinds of stuff we can give to developers, so they can address in a standardized way the fragmentation of the ecosystem as it is now,” said Georgiopoulos. “We believe we want to give developers a way to write down to the metal if they want. HTML5 gives them that capability.”
He said the Intel Developer Zone will be free for all developers, with some paid-for tools offered inside the network. “This is completely free, like it always has been. We've transitioned logins of developers, so basically all the people that have been using our facilities are auto-registered for this. Some of the tools are free, some are not.”
Intel also hopes the new Intel Developer Zone will spark participation in open-source projects from members. Specifically, Georgiopoulos mentioned Tizen, an effort to build a feature-phone operating system.
“We encourage developers to participate in our open-source projects there, specifically what we'll be doing with Tizen,” said Georgiopoulos. “We'll incentivize them to contribute collateral.”
Intel's new Developer Zone opens today.

Intel Adds Programming Support for Latest Silicon

We're only a little more than halfway through 2012, but Intel has already announced the 2013 versions Parallel Studio XE and Cluster Studio XE, two software suites that support x86-based parallel programming for high performance computing and beyond. Intel refreshes their software development offerings each year at about this time to sync up its tool support with the latest and greatest silicon and to add new features for developers. And since the chipmaker has been busy churning out new microarchitectures, there's lots of new software gadgetry.
The refresh will be especially interesting for HPC developers, since Intel is including full support for its upcoming Xeon Phi coprocessor, the chipmaker's manycore product line that is set to debut before the end of the year. Although Intel had beta versions of some of these Phi-capable tools and libraries prior to this, the 2013 toolset will provide complete support for HPC programmers developing codes for Knights Corner, the company's first commercial manycore offering.
By design, Xeon CPUs and Xeon Phi share the same basic x86 ISA. However, the SIMD instructions and vector width are not shared, so it's up to the compiler and libraries to abstract away that difference by automatically generating the appropriate code for the intended target -- which it does. But as we've reported before, tuning applications for optimal performance on Xeon Phi is more than likely going to involve code changes. Nevertheless, the ability to do a simple recompile and link on existing code to get a working Xeon Phi executable will remove a lot of pain and suffering while porting HPC applications.
The new Parallel Studio will also include compiler and tool support for "Ivy Bridge," the 22nm shrink of the Sandy Bridge microarchitecture. Again, Intel had support for these processors prior to this release, but they've been able to tune performance thanks to early customer feedback and in-house experience with the chips. Ivy Bridge parts for desktop and mobile platforms are already in the field; server versions are set to arrive next year.
Support for "Haswell," Intel's next microarchitecture following Ivy Bridge, has also been added. Haswell will include interesting goodies like transactional memory support, a feature that is designed to make parallel programming much easier since it automates the protection of shared data across threads. IBM's Blue Gene/Q chip implements this feature today and it's no big surprise that Intel has followed suit. The first Haswell CPUs should start shipping in 2013, although the server chips are not likely to arrive until the following year.
Beyond just supporting new silicon, Intel has also added a bunch of enhancements designed to make programming and debugging parallel apps easier. Some of major new features include:
Java profiling: Although Java is not used much in HPC codes, some financial applications do wrap Java around their performance-sensitive algorithms. This new profiling capability could help those users determine if those code bits are causing bottlenecks.
CPU power analysis: This is used to determine the sleep state of the processor to make sure unused resources are in their proper low-power mode. Obviously, if unused cores are spinning rather than sleeping, that just heats up the datacenter and make the utility companies richer.
Pointer checking: An option for the C/C++ compiler that determines when a pointer with a specified address range (one attached to a malloc, array or other data structure) starts accessing data outside its specified limits. This can be quite a useful feature since rogue pointers can silently corrupt your data, which as far as programmers are concerned, is the devil's work.
Heap growth analysis: Intel added a variety of new ways to run down memory leaks. Tracking them manually with a debugger or printf statement can be one of the most frustrating and tedious endeavors. Even if this feature only works some of the time, it's still worth it.
Conditional numerical reproducibility: This ensures that floating point calculations produce consistent results every time they are executed (assuming the same machine). Since the order of operations can change across different runs, rounding errors can generate somewhat different results, which while still valid, can be problematic for things like test suites and acceptance testing. The only downside to turning on this feature is a 10 to 20 percent performance penalty.
Fortunately, performance is usually going in the other direction. According to Intel Software director James Reinders, these latest C/C++ and Fortran compilers and runtime libraries are speedier than ever and among the best in the business. For AVX floating point operations in particular, the Intel C++ compiler outruns some of the more popular competition by a wide margin. Using the SPECfp_base2006 floating point benchmark, Intel generates code that executes 97 percent faster and 164 percent faster than that of Microsoft's Visual C++ and GCC, respectively.
Not everyone relies on fast compilers though. Reinders says their most demanding customers will resort to the analysis tools to get the ultimate in performance. "If you just want to do a recompile and link with a library, you can get a good speedup," he explains. "But if you want to start chasing how many TLB misses you have and get the compiler to push pages around so you can get the top score on something, we support that too."
Parallel Studio XE 2013 is available starting this week and retails at $1,599-$2,299 -- depending on if you want Fortran, C/C++ or both. Cluster Studio XE 2013 is basically a superset of Parallel Studio, adding MPI libraries and analysis tools, as well as a cluster installation utility. It retails for $2,949, and is scheduled to ship in the fourth quarter of 2012.
Intel unveils Parallel Studio XE 2013
By Alex Handy
SD Times
Intel will announce an update to its Parallel Studio development tools at next week’s Developer Forum. The update will include debugging support for Java and more reliable floating-point processes.
Intel's Parallel Studio XE 2013 includes a host of improvements aimed at saving developers time when building and troubleshooting multi-threaded and parallel applications. James Reinders, director of software products and an evangelist for Intel Software, said that, traditionally, the Parallel Studio tools have focused on Fortran and C++.
“Java, to us, is something that shows up in applications,” he said. “It's mixed in. Users want us to be able to tell them a little about that. Our tools do some of the debugging and find memory leak errors, and our performance tools have been extended to use Java. The Java runtimes today have hooks in them for performance tools to get info back. We can tell the computer is running something in the Java runtime. The users want to see which Java application was doing what. We're able to do that now. We've had some Java support in the past, but it was always limited to one JVM.”
Now, he added, Intel's Parallel Studio XE 2013 can attach to multiple JVMs running on the same system. That gives developers more flexibility to find problems that may exist across a Java application ecosystem.
But Parallel Studio XE 2013, and the company’s forthcoming HPC-focused Intel Cluster Studio XE 2013, both offer new capabilities for standard C++ and Fortran applications as well. Both software suites support C++11 and Fortran 2008, though there are still areas where said support is being filled in.
“No one has implemented C++11 and Fortran 2008 completely,” said Reinders. “We're working very hard to implement features. We're implementing them in order of customer feedback. We've made great strides, and we have most of C++11 and most of Fortran 2008 done, but we aren't ready to say everything is done.”
Still, there are plenty of new features for users of the traditional versions of these languages as well. Chief among them is the new ability to lock floating-point numbers into place, to prevent variables from changing between application usage.
Reinders said this comes from “conditional numeric reproducibility. It's about floating-point numbers. I think a lot of people don't think about it: We were taught in school [that] addition and multiplication are associative. Well, they're not associative if you do round off. Floating points are approximations. When you run programs multiple times, if it computes the math at all differently, you could get different results. They shake your ability to be confident your program is stable.
“So we've implemented things to allow the programmer to take control of that, and ask our libraries and compilers to ensure the same math is done every run. That comes with a performance penalty, and in practice it's around 10% to 20%. Our customers are telling us the overhead is usually quite reasonable and having that reproducibility is valuable.”
Intel Parallel Studio XE 2013 is available in three versions: one for Fortran, one for C++ and one for both. The Fortran edition is US$1,899, the C++ edition is $1,599, and the mixed edition is $2,299. Later this year, Intel will ship Intel Cluster Studio XE 2013, which includes some additional tools targeted at the HPC market. Specifically, Intel Cluster Studio XE 2013 includes the new Intel Message Passing Interface library, as well as the Intel Trace Analyzer and Collector. Intel Cluster Studio XE 2013 will cost $2,949.
All of these new capabilities make Intel's Parallel Studio a useful tool for finding difficult bugs in multi-threaded programs. One example of this is the new heap growth analysis available in this version. This new capability can be used to track down memory leaks.
“As people take programs and add parallelism to them, they find that they're debugging a program that has concurrency, and that's not easy,” said Reinders. “Problems can happen many different ways. Even if you make a simple programming error, in a program with thousands of threads, there's so much that can happen, it's difficult to envision where the source of the error is. We've extended traditional error-checking methods or made them work in parallel environments.
The traditional definition of a memory leak is a piece of memory that was allocated, and all references and pointers to it are obliterated, and it was never released back to the OS, so it's lost without any benefit to the application.
“Memory leak tools look at all memory and find lost memory. But there's another case where a program's logic has gone awry and it’s keeping memory and keeping pointers, so it’s not considered a leak. What we can do is give the user a number of intuitive tools to track how much heap usage they have at given points in time, and to look at if there's steady growth happening.”

Intel has shown off two new versions of its development suites for developers wanting to build shared memory and distributed applications.
Intel Parallel Studio XE 2012 has been released today, and is aimed at developers who want to build shared memory applications. It includes Intel C++ and Fortran compilers, and threading, math, multimedia and signal processing performance libraries.
The software comes with extensions that provide parallelism models that you can simply use in your applications. One extension, Intel Cilk Plus, is designed to improve the performance of programs on multicore and manycore processors. You use it simply by including three keywords in your app, and there are runtime and template libraries that show how to put together a well-tuned environment for building parallel applications.
Intel Threading Building Blocks is a C++ template library for creating high performance, scalable parallel applications. The library contains components that implement higher-level, task-based parallelism. Parallel Studio XE also includes a threading assistant for Linux and Windows. Intel Advisor XE can be used with C, C++, C# and Fortran. It finds the regions of your apps with the greatest performance potential from parallelism, shows the estimated speed-up, and identifies critical synchronization issues.
The other package, Intel Cluster Studio XE 2013, provides support for distributed and hybrid applications and will ship before the end of the year.
Both packages can be used to write apps to run on Intel Ivy Bridge Core processors or on Intel Xeon Phi many-core co-processors. There’s a trial version of the new version of Parallel Studio XE available for download from the Intel Software Evaluation Center.
The full version costs $2,299.

Applications built with the new suites would run on systems ranging from servers and clusters to desktops and Ultrabooks. "If you're in a Windows environment, these tools integrate with Visual Studio. If you're in a Linux environment, most people will use these standalone, or they'll use them along with the GNU tools like the GNU debugger," said James Reinders, a director with the Intel software products group.
Although the suites primarily are for building applications via C, C++, and Fortran, they also feature low-overhead Java profiling for applications that do include some Java code. "We're able to do analysis of the whole program, including the parts that are written in Java," Reinders said. Expanded support is included for C++ 11 and Fortran 2008.
A pointer-checker capability detects buffer overflows that can result in crashes and security. CPU power analysis is featured as well, along with improved MPI fault tolerance and, to check memory usage, heap growth analysis.
Parallel Studio XE is available today, while Cluster Studio XE is expected in November.

All Round PC
Known for its processor manufacturer Intel has only just introduced the latest version of its Parallel Studio development environment. The two new products are specifically aimed at application developers who want to make fast, stable and economical software.
The 2013er version of the software is optimized for use with the Ivy Bridge
microarchitecture and already with the upcoming Haswell architecture. Additionally, it is possible to program the also first appearing Intel Xeon Phi coprocessor technology with the software suite. Doing so, the development for the specific coprocessor indistinguishable from any other processor in order to relieve the programmer.
Further included in Parallel Studio XE 2013 and Cluster Studio XE 2013 many new analysis tools to test their own software development through its paces and optimize. Including, for example, is also the measurement of performance of the processor when running the application. Use is made of the advanced C + + '11, then on the advanced 2008 and the MPI 2.2 standard. Featuring the Intel C + + Compiler 13.0 will also work from 54 to 164% faster than competing products, thus effectively save time.
Another innovation is the parallelization assistant that helps the developer in optimizing their own program on the multi-core operation. Here, the code is analyzed and highlighted effective and ineffective ways of programming. Intel wants to give the developer using this wizard feel a multicore-experienced senior developer to have to side. The software Parallel Studio XE 2013 is available today at a price of 2,229 U.S. $. The Cluster Studio XE 2013 version follows in November (Q4) at a price of 2,949 U.S. $.
New Intel compiler support Xeon Phi and Haswell
By Andreas Sebayang
Golem.de
Intel has announced new versions of its developer tools. They should better parallelize tasks. In addition to the existing Ivy Bridge architecture will also have changes in the Haswell architecture of version 13 considered.
The new developer tools Parallel Studio and Cluster Studio 2013 have been announced by Intel. Therefore, the compiler for C + + and Fortran were raised to the version 13. The new compiler will primarily support parallel programming better. Besides optimizations for Ivy Bridge processors is also support for new architectures. So shall the coming processors under the code name Haswell be considered when compiling this. Haswell is expected in mid-2013 and is the next big leap in processor architecture.
Also supports the new Xeon Phi, previously known as the Knights Corner, a many-core card, which originally was to make Larrabee graphics card AMD and Nvidia competition .
The supported instruction set extensions next AVX includes AVX2, which only comes with Haswell. Intel also promises with the new compilers do not wake the processor cores and thus needlessly use energy saving features on modern Intel processors better. For better analysis, a developer can be displayed, a processor which uses frequency straight and which is part of the source code responsible for ensuring that a processor core from one of the sleep modes wakes. Should also be easier to find memory leaks and buffer overflows can be avoided even better.
Intel Parallel Studio XE 2013 is already available and costs around 2,300 U.S. dollars. The Cluster Studio version will cost 2949 U.S. dollars and in the fourth quarter of 2013 will be available. Intel hopes to release cluster studio still in November 2012.
Intel supports with his tools Windows, Linux, and sometimes Mac OS X.
