Experience

Northeast Parallel Architectures Center at Syracuse University          1991 - date

Cheng has participated in several MPP application projects at NPAC in the  area of 
financial modeling, electromagnetic scattering simulation, four-dimensional data 
assimilation, weather modeling and geographic information system.  Serving as a 
system analyst and a researcher in those projects, he has broad experience in 
developing scientific and industrial applications of parallel computing.

In a financial modeling project funded by Digital Equipment Co. and Syracuse 
University,  Cheng developed a set of parallel stock option pricing models on 
massively parallel systems, Connection Machines CM2 and CM5, DECmpp-12000, 
nCUBE2, and on networked workstations. He designed and implemented an interactive 
visualization environment for this application, in which computational models 
running on multiple MPP systems and workstations are coupled over  a local area 
network with a network-based graphical user interface.

Cheng has developed a high performance computing and visualization system for 
an electromagnetic scattering(EMS) simulation. In this DARPA-funded project, 
he integrated parallel EMS programs on the CM5 into an interactive data 
visualization environment to take the advantages of high performance computing 
and sophisticated 3D graphical display. 

Cheng is currently playing a major role in a NASA funded "Grand Challenge" 
application project in four-dimensional data assimilation. The goal of this 
project is to apply leading research in parallel software and algorithms to 
a number of existing techniques for data assimilation and to explore new 
data assimilation methodologies .

Cheng has also actively involved in a variety of other MPP application projects 
at NPAC.  He has extensive expertise in MPP software development, algorithm 
design and programming, including CM2/5(CMfortran, C*, CMMD, CMX11), DECmpp-12000 
(MPFortran, MPL, MPPE), nCUBE2(NDB), Intel iPSC/860(NX, Express, PVM); in network 
programming, including Express, PVM and TCP/IP, and in computer graphics, 
including X Window (Xlib, X toolkit and OSF/Motif), AVS, as well as in programming 
languages such as Fortran, C, C++, SQL, LISP, Prolog.

Information System Support Laboratory,  Virginia Tech, VA          March - August 1991

Working as an application analyst in the VirGIS(Virginia Geographic  
Information System) project, Cheng developed a vector-based spatial  database 
management and map display system which manages and generates  high quality 
graphics of DLG maps in many ways. 

Chengdu Institute of Computer Applications,  Chinese Academy of  Sciences    1988 - 1990

As a project leader or a software engineer, Cheng was involved  in a number of 
application projects in the area of artificial  intelligence programming environment, 
database and GIS systems,  and magnetic-card data processing products.
   
Chengdu Institute of Geography,  Chinese Academy of Sciences       1983 - 1985
                            
Cheng was working as an application programmer in the area  of computer applications 
in earth science, particularly, GIS applications in mountain disasters.
