Can JMP Software's JSL operations use GPU acceleration?

lala — Sun, 16 Feb 2025 00:18:51 GMT

Currently, it's easy to leverage GPU acceleration for computations in Python. Can this be achieved using JSL alone?

Thanks Experts!

Here is a recent reply to a discussion item from MZWald of the JMP Staff about multiple core usage and GPU's

Some platforms in JMP only use a single thread so having many threads wouldn't add much value, but having that single thread running at a faster frequency would add value. Some platforms in JMP do take advantage of multiple threads so having more threads/cores does help.

With the Torch add-in in JMP Pro 18, now for the first time a GPU will be utilized for image classification and deep learning which does those tasks orders of magnitude faster than a CPU.

How can to JSL？

At present, you can't.

Using Python and either PyCUDA or pyOpenCL is about the only way to access GPUs from scripting in JMP. As shown in one of my previous posts, you can create user defined JSL functions that implement functionality in Python using the Python Execute(). This way you can write the GPU Code in Python, yet still present a JSL interface for the rest of your scripting.
