AVS Express, the world's most popular scientific visualization software is the industry standard in platform-independent, visual computing software and application development. AVS helps application developers, scientists, and engineers develop graphics-based applications and perform data visualization and analysis.

Supervisor : Stephen H Olson

Principal Software Engineer, AVS Express Technical Team

(, MIT Lincoln Lab)

Work : Design, port, debug and release tasks of AVS/Express Software on Windows, Linux (32 & 64 bit), Mac/Darwin, Solaris (32 & 64bit)

o

During release, my responsibilities included

project management through release cycle of AVS/Express on several high end

platform/architectures namely Windows, Linux - RedHat8/9/Enterprise Linux

2.1/3.0 (32 bit), RedHat Linux Itanium (64 bit), Mac OS X/Darwin,

SUN Solaris (32bit & 64bit), IBM RS 6000 AIX, HP-UX 11(32 &

64bit) SGI IRIX (N32 & N64).

o

Developed

InstallShield Project for AVS/Express Multipipe Edition on Windows with custom

installation option for AVS/Express Master component, AVS/Express Node

component & CaveLib component.

o

Automated release

engineering (build, test and release) for AVS/Express by writing Perl and shell

scripts. The scripts supported branch, label & changelist options

provided by Perforce SCM

o

Worked in the

re-implementation of AVS/Express core Object Manager and components implemented

in C/C++ to handle large datasets. Quantities

like the number of nodes in a field and array dimensions can be represented by

64-bit integers (on 64-bit platforms).

o

Studied readFLD and readUCD field file format and implemented

writeFLD (AVS field file to read and write data) and writeUCD (Unstructured

Cell Data format) file formats in C.

o

Implemented

examples in Java/C to demonstrate the ability to read different data types

using HDF file format in AVS/Express.

o

Ported

AVS/Express to Darwin 7/Mac OS X, RedHat 8, 9, RedHat Enterprise Linux 3.0

and RedHat 2.1 on Itanium.

o

Identified and

fixed memory leaks in Graphics Display (GD) Kit of AVS/Express using Valgrind

and Purify memory debug tools.

o

Developed ActiveX

Control Demo Project explaining how to use AVS/Express & Microsoft Visual

C++ to create an ActiveX Control.Teaching Assistant (Aug 1999 - Dec 2000)

Department of Computer Science, University of Missouri-Columbia, USA.

Courses : Object Oriented Programming using Java

Algoithm Design & Programming

Organized the course material, lectured, set & graded assignments, monthly test & final exam, office hours, final grading.

Software Engineer Intern (June 1999 - Aug 1999)

NASA Goddard,Washington D.C.

Program : Visiting Student Enrichment Program

Michael Manyin

The (IISS) was developed as a scientific visualization tool for NASA's Mission to Planet Earth program to enable quantitative visualization and analysis of large datasets from earth observing system satellites, especially with meteorological applications. The IISS is an interactive visual spreadsheet collaborative environment for visualizing, interpreting, comparing, organizing, and analyzing extremely large hyper-image remote sensing datasets and 3-D volumetric numerical model results. During this on-going research, implemented - a high performance platform independent implementation of Loop module of IISS.worked on implementing bitwise image processing operators in C & C++ for different data types.
