Leumi Bank in Israel had a problem. It has very intensive I/O branch applications serving approximately one million customers. For clients who are buying and selling stocks, the bank has to complete its computer run and calculate the taxes overnight. It was running out of time.
“We have typical commercial banking applications that includes online applications to our branches,” explained Eli Alperin, head of infrastructure and technology division. We run overnight for online services and we have to be prepared with all our data at 8 a.m.” The tax application was very complex and had heavy I/O demands. The bank considered rewriting the program to run in parallel, but it was a sensitive application they felt would be risky to revise.
