AIMS (Automated Instrumentation and Monitoring System)
AIMS is a software toolkit that facilitates performance evaluation of parallel applications on multiprocessors. It consists of a suite of software tools for measuring and analyzing performance of FORTRAN and C message-passing programs written using the NX, PVM, or MPI communication libraries. AIMS can be used to illustrate algorithm behavior, help analyze program execution, and highlight problem areas that can then be modified to improve program execution.

The Chimera Grid Tools (CGT) software is a package containing a variety of tools for the Chimera overset grid approach for solving Computational Fluid Dynamics (CFD) problems. The Chimera approach has been found to be a very powerful method for solving complex configuration fluid dynamics problems. The package contains programs which can be used to perform: surface grid generation; volume grid generation; grid manipulation, smoothing, and projection; input preparation for domain connectivity utilities and flow solvers. It also contains post-processing tools for surface data extraction, surface pressure cuts, velocity profile extraction, and force and moment integration. It also contains a program known as OVERGRID, which serves as a graphical user interface to most of the package tools.

INS2D
The INS2D code solves the incompressible Navier-Stokes equations in two-dimensional generalized coordinates for both steady-state and time varying flow. The equations are formulated into a hyperbolic set of PDE using the method of artificial compressibility. The convective terms are differenced using an upwind biased flux-difference splitting. The equations are solved using an implicit line-relaxation scheme. The code is written for single or multiple-zone calculations. It can utilize either pointwise continious zonal interfaces, or random overlapped zonal interfaces if a PEGSUS interpolation database is supplied. The flow solver contains pre-coded boundary conditions for slip and noslip walls, symmetry planes, inflow and outflow boundaries, and far-field boundaries.

The INS2D code is written in Fortran 77, with some extensions and several routines which are written in C. The source code comes ready to compile and run on either a Cray computer or a Silicon Graphics workstation.

INS3D
The INS3D code solves the incompressible Naiver-Stokes equations in three-dimensional generalized coordinates for both steady-state and time varying flow. The equations are formulated into a hyperbolic set of PDE using the method of artificial compressibility. The convective terms are differenced using an upwind biased flux-difference splitting. The equations are solved using an implicit line-relaxation scheme. The code is written for single or multiple-zone calculations.

NAS Trace Visualizer
The NAS Trace Visualizer (NTV) is a trace visualization tool for trace files produced using The IBM Parallel Environment for AIX, Version 2.1, or later, or the Automated Instrumentation and Monitoring System (AIMS, Version 3. NTV detects the trace type, so the same version of NTV works for both trace formats. Performance profiling information is also produced and displayed.

Noshell
Noshell is a replacement shell to track access to disabled accounts. When an account is disabled, the shell field is changed to noshell. When someone accesses a disabled account (either login, rlogin, telnet, rsh, rcp or ftp) a message will be sent to a designated account. This message reports on the remote host attempting access, and if available, the remote user.

NAS Parallel Benchmarks (NPB/NGB)
NAS Parallel Benchmarks (NPB)
The NAS Parallel Benchmarks have been developed for performance evaluation of highly parallel supercomputers. These benchmarks consist of five parallel kernels and three simulated application benchmarks. Together they mimic the computation and data movement characteristics of large-scale CFD applications. In version 2.4, options for measuring I/O were added. In version 3.0 new parallelization paradigms were added. In version 3.0-MZ, a multi-zone capability for testing multi-level parallelism was added.

OVERMAGG
OVERMAGG is an automated script system used to perform OVERset Multi-element Airfoil Grid Generation. It is a collection of FORTRAN programs and C-shell scripts. It is capable of generating overset grids for an airfoil which may or may not include a leading-edge slat, and/or multiple-slotted flaps. Given the surface definition of the airfoil elements, the script-system will: generate surface grids, generate volume grids, generate box grids which surround the airfoil and extend to the farfield, run software to perform hole-cutting and generate interpolation stencils for updating overset boundaries, and generate boundary condition and flow-solver inputs for either the INS2D or OVERFLOW code.

OVERMAGG requires the Chimera Grid Tools software, and either the PEGSUS 4.1 or the PEGASUS 5.1 software.

Pegasus 5
PEGASUS 5 is the latest version of the PEGASUS series of mesh interpolation codes. The main purpose for the development of this latest version was to significantly decrease the number of user inputs required and to allow for easier operation of the code. The result is a process which is automatic for many flow analysis problems. All that is required from the user is the OVERFLOW input file and the volume grids. Other cases will require some additional input from the user.
