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 organization to modernize their existing applications on IBM System z, zEnterprise, and IBM Power Systems. These compilers enable:
- 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
