Hsinchu County/City, Taiwan

a software developers in data segmentation, and distribution with parallel computing in NCHC－ 6 years experiences in the National Center for High-performance Computing from 2006 ~ 2012.Scientific data visualization－Effective visualization helps developers/users in analyzing and reasoning about data from those evidence. Display tremendous scientific data to the large display wall (LDW) system.Parallel computing－data distributions and parallel via misc distribution library such as chromium, MPI, or OpenMP. 3D computer graphics, rendering engine and pipeline－including computer graphics in texture, shading, primitives, modeling transformations, lighting, clipping. Computer graphics rendering 3D objects based on OpenGL library.Volume Rendering－a set of techniques used to display a 2D projection of a 3D discretely sampled data set, typically in a 3D scalar field, commonly used in scientific visualization and computer graphics. A volume viewed by extracting isosurfaces (surfaces of equal values) from the volume and rendering as polygonal meshes, or by rendering the volume directly as a block of data.Rendering huge medical images of the CT/DICOM format－DICOM is a standard for handling, storing, printing, and transmitting information in medical imaging, created by the NEMA, for a network communication protocol and the distribution and viewing of CT scans, MRIs, and ultrasound.Display scientific data in LDW－Utilization of ParaView, VTK and ITK library to achieve the implementation of a volume rendering for a human CT medical image data, up to 8GB in the LDW system.Scalability, High Availability, Highly Accesible Server Farm－academic scientific computing services in NCHC, accomplishment of a more reliable, highly available, easily scalable, and providing non-stopping academic services, Ganglia, RRDtool, and a network load balancer...etc. the server farm scaled to handle clusters within 2000 nodes.

Parallel Computing, Cluster/Grid Network AdministrationInstallation/configurations of Cluster/Grid, High Performance Computing, Scientific Calculation4 years of cluster/grid maintenance and network administration－from 2002 ~ 2006 in the NTU-HEP group.Router configurations－setting up of the CISCO router configurationsFirewall configurations－ firewall rules of IP masquerading, the PREROUTING/POSTROUTING in NAT, and INPUT/OUTPUT/FORWARD via iptables.Scientific calculation－academic cooperation, researches for the new physics of the fundamental particles between the NTU-HEP and the Belle/KeK group in Japan.Text Processing－extractions of plain-text, images from misc document format such as pdf, doc/docx, and html/xml...etc.Administrative Documentations and Manuals of Configuration/Installation for the Server Farm in NTU-HEP－network administration documentation in NTU-HEP by means of docutil, an open-source text processing system, for processing plain-text reStructuredText, a markup language, documentation into useful formats such as HTML, LaTeX, man-pages, and XML.

Xindian, Taipei City

4 years of system integration engineer－from 1998 ~ 2002 in LEO System Inc., a branched subsidiary company of FIC group.Benchmark tests for compatibility/performance－PCMark rendering heavy tasks to simulate the PC/server severe workloads, and 3DMark on the other hands, was tests on the GPU system.Innovative system integration engineer－offering four years of experience in the full system integration compatibility, development lifecycle of PCs/Servers – through delivery of next-generation applications and solutions to provide highly compatible PCs/Servers.Wintel/Lintel compatibility – providing servers more stability based on windows/Linux OS.Misc Linux distro－Mandrake, Redhat, Archlinux, Fedora, CentOS..., and CLE (Chinese for Linux Extensions).Highly IO bus via SCSI architect－installation of the high through-put performances I/O bus, with SCSI hard-drive.Raid Storage－A disk array controller, managing the physical disk drives and represented as logical units, almost always implements hardware RAID. RAID also often provides additional disk cache. Backup Strategies－ Integrity, checksum of the filesystem via linux utilites - fsck. Experiences of backup strategies, including full, differential, incremental, and remote backup to restore the data and prevention of data disaster for business, industry, enterprise entity.MIB Parser－mib file parsed to generate a list of devices and OID information via python Snimpy library. Experienced troubleshoots in error SMI (Structure of Management Information) code. Network Administrative Features－ snmpget, snmpset and snmpwalk in the net-snmp library, however, are hard to use in shell scripts, and snmptranslate converts the OID to display information drawn from the MIB files themselves. PySNMP, a python snmp library, can be implemented as to retrieve and modify equipment's' configuration.
