GPU Acceleration

In preparation: Acceleration with Graphics Processing Units.

We plan on implementing GPU acceleration using the CUDA development platform. GPU acceleration will be integrated at a low level with our PixInsight Class Library C++ development framework, so it will be available to the PixInsight core application—including native implementations of JavaScript runtime objects—and most existing tools. Hopefully the first GPU-accelerated versions of PixInsight will become available during 2015. Stay tuned!

Processor

Minimum required processor: Intel Core Duo or equivalent.
Minimum reasonable processor: Intel Core i5 or equivalent.
Minimum recommended processor: Intel quad-core Xeon, quad-core Core i7, or similar.
Recommended performance processors: Intel Xeon E5-2697 v3 @ 2.60GHz / Intel Xeon E5-2680 v3 @ 2.50GHz / Intel Xeon E5-2697 v2 @ 2.70GHz / Intel Xeon E5-2695 v2 @ 2.40GHz / Intel Core i7-5960X @ 3.00GHz / Intel Core i7-4960X @ 3.60GHz.
By default, the PixInsight platform will use all processors and processor cores available on your machine. There are specific preferences settings to control the maximum number of processors used by PixInsight, along with other parallel execution options such as thread execution priority, thread processor affinity, etc.

See the PixInsight Benchmark community-driven project for up-to-date information on hardware performance.

RAM

Minimum required amount of RAM: 4 GiB on a 64-bit machine and operating system.
Minimum reasonable amount of RAM: 8 GiB on a 64-bit machine and operating system.
Recommended performance RAM: From 16 GiB to 64 GiB (depending on the sizes and number of images to process) on a 64-bit machine and operating system.
Being a 64-bit application, PixInsight has no practical memory limit. It will use all memory available to applications, and will cause the operating system to allocate virtual memory on disk when necessary.
