HP-UX 11i Release Notes: HP 9000 Computers > Chapter 4 HP-UX 11i Operating Environments
HP-UX 11i Technical Computing Operating Environment (new) |
|
|
The HP-UX 11i Technical Computing Operating Environment includes these applications:
The FirstSpace VRML (Virtual Reality Markup Language) Viewer Version B.11.11 allows you to "drag-and-drop" a VRML model in the view space for viewing. FirstSpace has changed from revision 1a to 1.10. The HP 3D Technology for the Java Platform Version 1.1.3a contains the classes for creating 3D applications. The HP 3D Technology for the Java Platform may be distributed with your Java applications as long as you adhere to the terms of the LICENSE file. Vendors also need to include an installer. This release for HP-UX 11i is a maintenance release which provides numerous defect fixes. In addition, some improvements have been made in the area of memory release. An enhancement has been made to ensure that Java 3D releases memory when a branch graph is detached from the scene graph. In some cases however, you may need to detach the View from the scene graph to release the memory. Prerequisites are HP-UX Software Developer's Kit (SDK) for Java version 1.2.2.x, and the HP-UX 700 OpenGL 3D Graphics Runtime Environment (B6268AA). High Performance Math Libraries (HP MLIB) Version B.07.01 contains both the Linear Algebra Package (LAPACK) and the Vector Library (VECLIB) subprograms, providing mathematical software and computational kernels for engineering and scientific applications involving linear equations, least squares, eigenvalue problems, and the singular value decomposition. New features include:
HP MLIB incorporates algorithmic improvements, and several tunable parameters are adjusted for good execution performance. You can use HP MLIB as archive or shared libraries. Performance of your applications is better when you use archive libraries. However, if you need to keep executable files small, you can use shared libraries on any PA-RISC 2.0 system running the HP-UX 11.0 or later operating system. VECLIB is optimized by using a highly efficient implementation of the Basic Linear Algebra Subprograms (BLAS), Levels 1, 2, and 3, as well as a subset of the newly-defined BLAS Standard. Performance for key BLAS routines has been improved. MLIB fully conforms to the public domain version 3.0 of LAPACK in all user-visible usage conventions. The internal workings of some subprograms have been tuned and optimized for Hewlett-Packard computers. This version simplifies sparse solver interface use and improves its performance. Version 4.0 of the METIS reordering technology has been incorporated. You can now use the C or C++ compiler to link applications built with MLIB. Previous to this release, you were required to link using the Fortran compiler when using VECLIB or LAPACK. For more detailed information, see:
Refer to the http://hp.com/go/mlib web site for additional product information. HP Message-Passing Interface (MPI) Version B.11.11 is a high-performance implementation of the Message-Passing Interface Standard. HP MPI complies fully with the 1.2 standard and partially with the 2.0 standard. HP MPI provides an application programming interface and software libraries to support parallel, message-passing applications. New features include:
HP MPI supports the TotalView debugger on HP-UX version 11.0 or later. You can collect profiling information for applications linked with the thread-compliant library in addition to those linked with the standard MPI library. Counter instrumentation (MPI_INSTR) is supported for the thread-compliant library regardless of thread level. Trace file generation (XMPI) is supported for all thread levels except MPI_THREAD_MULTIPLE. This release expands MPI-2 support by supporting MPI-2 object naming routines. The new error checking flag (-ck) allows you to check appfile set-up, host machine and program availability, and file permissions without creating MPI processes. Timeout errors before MPI_Init that may have been seen in older versions of the product do not occur in this version because mpirun no longer makes assumptions about time to MPI_Init. The following HP MPI documentation is provided for 11i:
Refer to http://hp.com/go/mpi for the HP MPI Release Notes and other product information. HP Visualize Conference Version 1.4 (B.11.11.06) is a collaborative conferencing solution for HP Visualize UNIX Workstations that can interoperate with Microsoft's NetMeeting, Sun's SunForum, and SGI's SGImeeting products. Functionality changes have not occurred in HP Visualize Conference since version 1.3 was released. Version 1.3 added support for NetMeeting 3 while maintaining backward compatibility to version 1.2 and NetMeeting 2 via two running modes:
The HP-UX 11i release of HP Visualize Conference is functionally identical to HP Visualize Conference 1.4 for HP-UX 10.20. There is no impact on other system performance or other system components. HP Visualize Conference 1.4 (B.11.11.06) on HP-UX 11i is compatible with HP Visualize Conference on HP-UX 11.0 and 10.20, Microsoft's NetMeeting, Sun's SunForum, and SGI's SGImeeting. |
