Compilers

Keeping current on your mainframe compilers really does make a difference Read the MacFarlkand Consulting analyst whitepaper (US)

Improving system utilization by exploiting IBM architectures

IBM delivers industry-leading compiler optimization technology across multiple platforms. Compilers let you focus on the business logic of your application, while they find the best way to transform the source code for the target platform. Backed by IBM’s longstanding commitment to forward compatibility of hardware and software, IBM compilers improve programmer productivity by exploiting advances in hardware and advances in performance optimization, without requiring special coding or source code changes.

IBM compilers provide features for organizations to modernize their existing applications on IBM System z, zEnterprise, IBM Power Systems and IBM PureSystems. These compilers:

Integrate existing business-critical applications with dynamic Web applications
Support interoperability with Java and promote the exchange and usage of data with XML
Optimize the performance of commercial and high-performance computing workloads
Reduce CPU cycles consumed for a given task, maximizing your IBM hardware investments
