| SC98 Java Grande Panels -- DRAFT July 1 1998 |
To be held at SC98 Orlando for a total of 3 hours on the morning of Friday November 13
|
| Overview |
| This is a set of two linked panels, which will focus on the status, issues and futures of Java Grande and include a presentation of and public comment on the activities of the Java Grande forum. |
| Grande applications are large-scale applications typical of HPCC, scientific and engineering computations, or distributed simulations. |
| The goal of the Java Grande forum is to further community activities that will make Java a much better (and probably the best) programming environment for Grande applications. The first three meetings of the Forum were March 1,98 May 9-10 and August 6-7. The Panels will consist of presentations from the community covering technologies, applications and studies relevant to Java Grande, which will set the scene and give possibly controversial position papers. |
| The two Java Grande working groups will present their current findings and lead an open discussion. |
| The public comments will be integrated into revised versions of the working group reports. |
| Audience for both panels should include academia, government and industry. |
| The topics should interest people from both application and computer science (technology) fields. |
Leading questions and issues:
|
| Abstract of First Panel -- Java Grande I: Rationale, Status and the Forum |
| Moderator: Siamak Hassanzadeh (Sun Microsystems) |
| This panel will set the scene and present initial findings of the two Java Grande Forum working groups. It will consist of approximately 5 presentations. |
| The first part of the panel (of about 50 minutes) will consist of 3 presentations, which will define Java Grande and describe critical technologies, applications and performance studies of relevance to Java Grande. |
| Technologies could include nifty compilers or distributed computing infrastructure. Applications could include libraries or larger scale systems. |
| These talks will be designed to complement any related papers in the main SC98 technical sessions. |
| The final 40 minutes will feature the two forum working groups |
| Here we will briefly describe forum (goals and process) and present current state of findings of these two working groups. |
| Abstract of Second Panel -- Java Grande II: Issues and Futures |
| Moderator: Geoffrey Fox (Syracuse University) |
| This session will start with selected short (approximately 10 minute) presentations on alternative or augmentative ideas with goal of broadening the involved community. |
| Topics will include "experiences from Industry users" , views from world community (there is a relevant meeting in Europe(Cardiff) during the summer), and naysayers (Why Java Grande is doomed). |
| These talks will be chosen for their broad impact on Java Grande and not particularly their technical wizardry. We will actively solicit suggested contributors. |
| This 60 minute introduction will be followed by a debate of the two draft reports presented in previous panel. To encourage this, we will make the documents available on the web and on the exhibit floor before the meeting. |
| Audience comments will be incorporated into revised versions of the reports and will help set the agenda for future forum activities. |

We have had several conferences with 50---- attendees
|
Topics of conference papers:
|
| "Spun off" Java Grande forum to promote needed community standards and activities. |
| Must be proactive because Grande computer market is perhaps 1% of total computing market -- not Sun's highest priority |

The Java Language has several good design features
|
| Java has a very good set of libraries covering everything from commerce, multimedia, images to math functions (under development at http://math.nist.gov/javanumerics) |
| Java has best available electronic and paper training and support resources |
| Java is rapidly getting best integrated program development environments |
| Java naturally integrated with network and universal machine supports potentially powerful "write once-run anywhere" model |
| There is a large and growing trained labor force |
| Can we exploit this in Grande Computing / computational science? |

| Java has potential to be a better environment for "Grande application development" than any previous languages such as Fortran and C++ |
| The Forum Goal is to develop community consensus and recommendations for either changes to Java or establishment of standards (frameworks) for "Grande" libraries and services |
| These Language changes or frameworks are designed to realize "best ever Grande programming environment" |
| First Meeting Mar 1 Palo Alto at Java 98 -- 200 Attendees set Agenda -- 30 permanent people and further meetings May 9-10, Aug 6-7 |

1) Most important in the near term -- encourage Sun to make a few key changes in Java to allow it to be a complete efficient Grande Programming Language
|
2) As a community, recognize that sometimes standards are more appropriate than creativity and pool results of experiments to produce a Java Grande framework covering libraries and computer access
|
| 1) requires us to work with the computing mainstream -- 2) is internal to community |

We are initiating Community actions
|
| Note European involvement has been excellent so far |
| Now is a good time for full international community to comment on and participate in activities |

| Don't need to rewrite existing codes in Java! |
| Rather use Java freely at client and middle tier |
| One can wrap existing codes as CORBA or Java distributed objects |
| Conduct suitable experiments in using Java in complete Grande applications |
| Make certain your interests are represented in Java Grande Forum |
| Retrain your staff in Java Web and distributed object technologies |
| Put "High Performance Grande Forum compliant" Java support into your RFP's for hardware and software |
