Put your COBOL applications into HYPERDRIVE on z14 without having to recompile a single line of source
Advanced optimization and z hardware exploitation are key to improving application performance and reducing CPU utilization and operating costs. Gone are the days when COBOL applications will run faster simply by moving them to new z hardware. Performance increases delivered by modern z/architecture are more workload-targeted and require exploitation of new hardware features. Therefore, to maximize ROI, it’s important to stay current with compiler technology and selectively optimize CPU-intensive parts of the applications.
IBM Automatic Binary Optimizer (ABO) is a unique, cutting-edge technology designed to optimize the performance of COBOL program modules built with VS COBOL II v1.3 to Enterprise COBOL for z/OS v4.2 without the need for recompiling from program source. ABO uses advanced optimization technology shipped i

ABO v1.3 is complementary to Enterprise COBOL v6.2. Many development organizations only compile code that require source changes. By using ABO v1.3 together with Enterprise COBOL v6.2, clients can compile/optimize programs that require source changes with COBOL v6.2 and optimize modules they do not plan to recompile with ABO v1.3. This way, both CPU utilization and the operating costs of business-critical COBOL applications is reduced to maximize ROI without a major impact to existing development process.
