Improving system utilisation by exploiting IBM architectures

IBM delivers industry-leading compiler optimisation 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 optimisation, without requiring special coding or source code changes.

IBM compilers provide features for organisations to modernise 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
Optimise the performance of commercial and high-performance computing workloads
Reduce CPU cycles consumed for a given task, maximising your IBM hardware investments
