While APT can run on a more minimal system, we generally recommend a minimum of 4GB of memory and the equivalent of an Intel 3.6 GHz Pentium 4 (for example Dell OptiPlex GX620).
For very large data sets we recommend using a 64-bit computing platform and/or a compute farm; 64-bit versions of APT can leverage the extra memory on a 64-bit machine by reducing the number of iterations required to process the entire data set. Analysis of CytoScanHD arrays is not supported under 32 bit Windows.
Hardware/Software configurations used for internal testing of APT are listed below:
