Types of memory

When you are configuring your computer(s) for aPriori software, you must consider two kinds of memory:

  • RAM: the total hardware memory installed in your machine
  • Heap: portion of that memory which is allocated aPriori software.

Reasons for increasing heap

Since heap size determines how much memory is allocated exclusively to aPriori software, it can have a significant impact on how aPriori performs. If you work with many very complex CAD parts, you will probably benefit from increased RAM memory and an increased heap size setting.

To determine how much RAM, you should install and how large your heap size settings should be, please refer to “Basic Requirements” in the latest aPriori System Requirements document.

Types of aPriori heap

There are different heap size requirements and different procedures for adjusting heap size for:

  • aP Pro in Creo® direct integration mode
  • aP Pro in standalone mode
  • aP Pro bulk costing
  • aP Admin and aP Analytics

This section covers aP Pro, in both Creo® direct integration mode and in standalone mode. For adjusting heap for bulk costing procedures, see the aPriori System Requirements document. For aP Admin and aP Analytics, see the Enterprise Platform Installation Guide and the Cost in aPriori NX™ Plug-in Administration Guide.
