Speed up processing through GPUs

[marpet]

I’ve written a post some time ago about it:

Performance of snap desktop and snappy

No, these settings are not helpful to improve the performance of python code. Please not that python, by default, is not the fastest language. But there are ways to improve the speed. For example you can use numpy, especially when working with arrays. Also numexpr by be worth to have a look at. Just to give you an indication of what is possible. Recently we improved the performance of one algorithm from taking 3:40 h to 5 minutes. This was mainly achieved by using numpy.

Also increasing the available memory might help:

Snappy error - ProductIO.writeProduct

I’m not sure, I’m not very familiar with snappy, but I think you have to set a value in the jpyconfig.py script in the snappy folder. Try setting jvm_maxmem = None to jvm_maxmem = '6G' Another place to change the memory usage might be in snappy.ini in the snappy folder. Change the line # java_max_mem: 4G to e.g. java_max_mem: 6G
