CAChe Work System

CAChe Work System CAChe Scientific Tektronix, Inc. 

The semi-empirical molecular orbital calculation software MOPAC in the CAChe Work System for Windows ver. 6.01 (Fujitsu, Inc.) was used in all of calculations for optimization of geometry by the Eigenvector Following method, for search of potential energies of various geometries of intermediates by use of the program with Optimized map, for search of the reaction path from the reactants to the products via the transition state by calculation of the intrinsic reaction coordinate (IRC) [10]. 

Synchronous DRAM SDRAM works at the same speed as the system bus, up to lOOMHz. While the technology is significantly faster than other forms of DRAM memory, the speed increase is often not apparent because the system cache masks it. 

For 3-D modeling and FEA applications, a Pentium 100 MHz processor running on a 32-bit Windows NT operating system works significantly better. The minimum memory requirement for Windows NT is 32 MB and the operating system requires 160 MB of hard-drive space. The system should have a 16-K internal cache with 256 K to 512 K of external cache for increased performance. The monitor for these applications should be 21 inch with 0.25 ultrafine dot pitch, high resolution (1600 x 1280), and 65,536 colors Peripheral component interconnect (PCI) local bus (a high-bandwidth, processor-independent bus) and a minimum 1-GB SCSI-2 hard drive are also required.
