Confidential, Arlington, Virginia

Responsibilities:

• Senior designer/programmer in the prototype development of the Integrated Simulation Assessment of Air base Capability ( Confidential ) model, an 80286/MS-DOS based Monte Carlo discrete event simulation model. Confidential is written in Ada and makes extensive use of Ada generics and strong typing.
• Redesigned critical Confidential data structures in order to remove performance bottlenecks.
• Directed the conversion of low-level graphics subroutines in Confidential from real mode to protected mode.
• Rewrote one of the critical graphics subroutines in Confidential, reducing the time required to initialize from minutes to less than a second. This performance boost was achieved despite the fact that the original routine was written in assembler and the new one in Ada.
• Senior designer/programmer for the Terminal Virtual (TV) CPC in SAFE Delivery 2. SAFE is an online information system that incorporates message switching, real-time document dissemination, electronic mail, textual database management and specialized workstations in an integrated electronic office environment. Supporting thou­ sands of users, the system employs multiple 3090 and 308x processors operating under VM/SP HPO and Confidential /XA. Interactive computing is performed under CMS while Confidential is used for real-time document dissemination and database maintenance. Confidential 's portion of the SAFE system consisted of over 750K lines of IBM Assembler (H) source code that interfaced with another 1 million lines of code from other vendors. TV is the end-user interface for SAFE, and is written in Assembler (H) and REXX. It interfaces with a government-built office automation system, and also makes limited use of the under­ lying CMS environment of VM/SP Release 4.
