Supported Platforms

Currently, the full functionality of the PMOD modules is offered on three platforms:

• Windows Operating Systems starting from Windows 2000
• Linux
• MacOSX

Maintenance and Compatibility

PMOD is based on the Java Runtime Environment (JRE) which evolves over time. In order to avoid compatibility problems in the operation PMOD is deployed with a tailored JRE on Windows and Linux systems. On MacOSX systems however, the JRE is a part of the operating system and can therefore not be tailored. If a MacOSX upgrade happens to cause an incompatibility, PMOD Technologies will react and provide a new build of the current release to be freely downloaded using the customer's support login on the PMOD website.

Note, however, that prior versions of PMOD will not be fixed. Therefore we recommend that the user of PMOD versions older than 3.1 do not upgrade their system JRE.

Performance

The performance of PMOD is crucially dependent on the

• CPU clock: Java performance increases approximately linearly with the CPU clock; a better internal organization of a CPU usually does not compensate a higher clock rate.
• Cores: The pixel-wise modeling tools supports parallel calculations, if a system has more than 2 cores or CPUs. Systems with 4 and more cores will therefore calculate parametric maps significantly faster.
• Operating system: To process large data sets it is mandatory to use 64-Bit operating systems. With 32-Bit systems, the RAM available to PMOD is limited to <2GB, and in practice only about 1.2-1.5GB can be used!
• RAM: The use of at least 4GB together with a 64-Bit system is highly recommended to avoid swapping and running out of memory.
