Oprofile works well with Java code. The JIT compiler has enough smarts to register dynamically-generated code with oprofile, and you get the added benefit that you're profiling native code, not just Java. Like I said, hard to beat.

Recently (7.3) it happens sometimes that the socket connexion is lost with the profiled application. In pisces context, I use the bootstrap prepend option to inject my patched classes into the openjdk jvm. Then netbeans is unable to instrument them. Moreover, I use the instrument mode over sampling because I want accurate method call counters and I advocate it is still difficult / obscure how to tell netbeans which classes to instrument or set profiling points: it often profiles nothing when I try tuning them.

Apparently, I understood the documentation and the default CPU_CLK_UNHALTED setting is perfect. Moreover, it is able to annotate java source code (dtrace like) and it is so easy: opannotate --source -o src/ -t 0.1 --search-dirs=/home/bourgesl/libs/openjdk/pisces/src/sun/java2d/pisces/ PS: It would be so great if there is a netbeans plugin (apparently an eclipse one exists in the fedora packages) ...

Part of the discussion on this is in the comment section of the following blog which I had with David Homes: https://blogs.oracle.com/dholmes/entry/minimize_garbage_generation Many Java objects can either be allocated on the stack as well as deleted if allocated in the heap without it being passed for GC. Since stack allocation will only work for some objects and will break the current memory model an annotation can be introduced to mark stack allocation. Any contained objects cannot outlive the containing object in this case unless they are annotated to escape. Escaping objects can be heap allocated and collected through the normal GC process. If an object is heap allocated it can be deleted at define points like block exit, return or end of iteration (in loops) etc. Appropriate annotation can be introduced to mark the deletion. In this case contained objects can out live the containing object. The objects that cannot be deleted will be marked for GC during the normal GC cycle. Also an annotation can be introduced to help mark fields and methods which might escape and which does not statically. For methods all parameters, local variables and returned objects will not escape thus can be deleted after method returns. For methods parameters, any objects passed will not escape and can be safely deleted after method returns. Not all parameters may be marked. For fields, the objects can be deleted when the containing object is deleted. These objects if returned from a method will be clones and any pass to methods which are not marked for non escape would be clones else the compiler should complain. For local variables, they can be deleted when method returns or go out of scope. Also for return values an annotation to mark the return value safe to delete after returning. More fine grain resource management can be done through annotation like calling close() before trying to GC with appropriate annotations. Also appropriate API can be defined also to perform some of the memory management operations. For further examples of possible annotations see the discussion on: https://blogs.oracle.com/dholmes/entry/minimize_garbage_generation Also ability to turn off GC within a code block or function unless an outofmemory error happens. This would leave lesser workload for the GC system. Large part of memory management workload will be at know at appropriate point in code (if the programmer is disciplined). In GCing we do not know where the execution is when GC happens. If this is in latency sensitive code block you are in trouble. This way the developer is in true partnership with the GC and memory management system. Suminda -- Suminda Sirinath Salpitikorala Dharmasena, B.Sc. Comp. & I.S. (Hon.) Lond., P.G.Dip. Ind. Maths.

As Doug said jvm.cpp is the native implementations for a bunch of native method defined in the JDK libraries. Look for JVM_ methods. Some of those Java-level methods may also be subject to intrinsification by C1/C2 in which case the JVM_ version will only be used from interpreted code.

For the record, together with the GNU Classpath and IcedTea communities we decided to do this experiment, and allocated one resource to help students to be introduced to OpenJDK development. The project is still part of the GNU Classpath umbrella and will be followed by GNU Classpath people. If the experiment will succeed, we may try to turn next year into a proper organisation fully dedicated to OpenJDK. I will be mentoring Elisa, and the code will be probably hosted on the icedtea server once ready for use (although for the time being we will develop the code on an external repository until everything is set correctly). Once again, welcome Elisa! Cheers, Mario From danilo.ansaloni at usi.ch Thu May 30 16:43:10 2013 From: danilo.ansaloni at usi.ch (danilo.ansaloni at usi.ch) Date: Thu, 30 May 2013 16:43:10 +0000 Subject: Modularity 2014 - Call for Papers Message-ID: *** MODULARITY 2014 *** 13th International Conference on Modularity April 22-26, 2014 Lugano, Switzerland http://aosd.net/2014/ In cooperation with: * ACM SIGSOFT * ACM SIGPLAN CALL FOR PAPERS - RESEARCH RESULTS TRACK Modularity at the semantic as well as the syntactic level is a key enabler for the expression of high quality software systems, because one of the most important techniques for complexity reduction in any context is separation of concerns. Novel concepts and abstraction mechanisms including aspect-oriented techniques are a focus point for improvements in the support for modularity. The scope of this effort covers all perspectives on software systems in all their life-cycle phases, for instance application domain analysis, programming language constructs, formal proofs of system properties, program state visualization in debuggers, performance improvements in compiler algorithms, etc. As the premier international conference on modularity, Modularity continues to advance our understanding of these issues and the expressive power of known techniques. The Modularity 2014 conference invites full, scholarly papers of the highest quality on new ideas and results. Papers are expected to contribute significant new research results with rigorous and substantial validation of specific technical claims, based on scientifically sound reflections on experience, analysis, experimentation, or formal models. Compelling new ideas are especially welcome, which means that the requirements in the areas of validation and maturity are higher for papers that contribute more incremental results. Modularity 2014 is deeply committed to eliciting works of the highest caliber. To this aim, two separate paper submission deadlines and review stages are offered. A paper accepted in any round will be published in the proceedings and presented at the conference. Promising papers submitted in the first round that are not accepted may be invited to be revised and resubmitted for review by the same reviewers in the second round. Authors of such invited resubmissions are asked to also submit a letter explaining the revisions made to the paper to address the reviewers' concerns. While there is no guarantee that an invited resubmission will be accepted, this procedure (similar to major revisions requested by journals) is designed to help authors of promising work get their papers into the conference. Submission to both rounds is open for all, and authors who submit to the first round may of course choose to resubmit a revised version in the second round without such an invitation, in which case new reviewers may be appointed. Finally, the same paper cannot be simultaneously submitted to other conferences or journals. In case of doubt, please get in touch with the Program Chair. TOPICS Topics of interest include, but are not limited to, the following: * Varieties of modularity. Context orientation; feature orientation; generative programming; aspect orientation; software product lines; traits; families of classes; meta-programming and reflection; components; view-based development. * Programming languages. Support for modularity related abstraction in: language design; verification, contracts, and static program analysis; compilation, interpretation, and runtime support; formal languages and calculi; execution environments and dynamic weaving; dynamic languages; domain-specific languages. * Software design and engineering. Requirements and domain engineering; architecture; synthesis; evolution; metrics and evaluation; empirical studies of existing software; economics; testing and verification; semantics; composition and interference; traceability; methodologies; patterns. * Tools. Crosscutting views; refactoring; evolution and reverse engineering; aspect mining; support for new language constructs. * Applications.
