Abstract : The VAX 11/750 was purchased from Digital Electronics in the Spring of 1985. According to our benchmarks using GAUSSIAN82 and GAMESS, VAX throughput is approximately 1/13th of an IBM 3081. The reliability of the computer has been excellent. In the approximately 18 months since the computer was obtained, there has been virtually no down time, except for that caused by air conditioning failure or to install software updates. This has allowed us to run jobs which require several CPU days to be completed. This would clearly be impossible on any campus machine. The system has 900 megabytes of disk storage, and the main memory has been upgraded to 8 megabytes. This allows us to perform calculations on very large molecules. Because it is so easy to use the VAX VMS operating system, nearly all of our program development is performed on the VAX.
