| <strong>Time:</strong> 1:00 PM EST</p> |
| <p><strong>Attendees:</strong></p> |
| <p>Rod Mach, Absoft<br> |
| Beth Tibbitts, IBM<br> |
| Bill Chung, IBM<br> |
| Don Pazel, IBM<br> |
| Wyatt Spear, University of Oregon<br> |
| Greg Watson, LANL <br> |
| Nathan Debardeleben, LANL <br> |
| Craig Rasmussen, LANL <br> |
| Gregor von Laszewski, Argonne National Lab</p> |
| <ol> |
| <li><b>FDT Status</b> <br> |
| Craig reports the FDT release is fairly static since December. |
| Integration with Photran has caused some problems. Currently the FDT |
| is more stable than Photran. Craig has added a refactoring action, of |
| refactoring reals to double precision. |
| <p> |
| <li><b>PTP Team Status</b> <br> |
| Nathan is only 1/2 time on PTP now. <br> |
| New PTP team member: Randy Roberts from LANL, also 1/2 time. Randy |
| will focus on Job Scheduling systems, and remote systems. |
| <p>Will need testers soon for binary build. Beth and Wyatt |
| volunteered for Linux testing.</p> |
| <p> |
| <li><b>EclipseCon</b> <br> |
| <a href="http://eclipseCon.org">EclipseCon</a> is March 20-23, 2006 |
| in Santa Clara, CA. |
| <ul> |
| <li>Greg's PTP "long talk" entitled <a |
| href="http://www.eclipsecon.org/2006/Sub.do?id=265">Parallel |
| Application Development With Eclipse</a> is Tuesday at 3:15. |
| <li>[Addendum Feb. 27] A Demo entitled <a |
| href="http://www.eclipsecon.org/2006/Sub.do?id=507"> Parallel Tools |
| Platform Demo</a> has also been accepted and will presented by Beth |
| Tibbitts - Wednesday at 2:00 pm (with a little help from her |
| friends). Nathan had suggested a portable bproc cluster would be |
| good for this? |
| <li>A BOF (Birds of a Feather) session will be scheduled one |
| evening. Date/Time to be determined. |
| <li>CDT Conference is scheduled for Friday March 24. |
| <br>Univ. Houston - CDT changes - Craig/Greg |
| </ul> |
| <p> |
| <li><b>MPI and OpenMP Development tools</b> |
| <br>Beth Tibbitts from IBM reported that the OpenMP tools are almost |
| done to the level of the MPI tools (finding artifacts, help, content assist, |
| hover help, etc.). Also some beginnings of static analysis in finding |
| regions applicable to #pragma scope. |
| <p> |
| <li><b>Commodity Grid (CoG)</b><br>Gregor von Laszewski from ANL gave a <a |
| href="http://wiki.cogkit.org/images/4/45/Cog-eclipse.ppt">presentation</a> |
| on the possible integration of the Commodity Grid (CoG) Kit with |
| Eclipse PTP. |
| <p> |
| <li><b>Parallel Debugger (Greg)</b> <br> |
| Debugger features being worked onover the next year include: |
| <ol> |
| <li>Missing CDT functionality - conditional breakpoints, hit counts, |
| signals, memory view, etc. |
| <li>Parallel Visualization - e.g. view variables from a range of |
| processes. Viewing specific data structions, such as arrays, better. |
| |
| <li>MPI-specific debugging: debugger needs knowledge of messages, |
| communicators, etc. |
| </ol> |
| <p> |
| <li><b>PTP Scalability (Greg)</b> |
| <ol> |
| <li>Baseline study: how scalable is it now? Greg has 256-node |
| cluster, 4 proc per node = 1024 processors. Expects o(n) scaling - |
| confirmed. Startup was 15 sec.; debug operations were 7 sec per |
| operation. This is comparable to TotalView for 1K processes. |
| <li>Plans: (a) take advantage of MPI collectives e.g. broadcast |
| communication, to control debug processes more effiently. <br> |
| (b) add a process hierarchy so don't need to scan across all |
| processes. Want to scale to 10K+ processes. |
| </ol> |
| <p> |
| <li><b>Current PTP release</b> <br> |
| Builds should be ready this week; Release should be shortly after |
| that. |
| <p>Target pre-reqs: |
| <ul> |
| <li>Java 1.4 |
| <li>CDT 3.0.x |
| <li>Eclipse 3.1 |
| </ul> |
| <p> |
| <li><b>TAU plug-in (Wyatt)</b> <a |
| href="http://www.cs.uoregon.edu/research/tau/home.php">TAU</a> |
| (Tuning and Analysis Utilities) plug-in should be available soon. |
| <p> |
| <li><b>Miscellaneous</b> |
| <br>Next meeting March 14 |
