What are the CPU, GPU, RAM and storage requirements?

The minimum specifications to run StarTools depends mostly on the resolution the data you intend to process.

Low resolution data sets (for example from a 1MP CCD or Webcam) may be processed successfully on a Pentium 4 with 512Mb RAM. High-resolution data sets, such as those from a DSLR typically require at least 4Gb of RAM. For best results, 16GB and a modern many-core CPU are recommended, in addition to running from a RAM disk (or alternatively a Solid State Drive).

As of version 1.7 StarTools is fully GPU accelerated. Heavy arithmetic is offloaded to any OpenCL 1.1 compliant GPU present in your system. Significant processing speed can be seen on even modest, older GPUs.

Regardless of your machine's specification, consider binning your data if your data is oversampled.
