[Numpy-discussion] Re: New feature

For a start you could share the link for the stand-alone package here, with a short description of what it does. Additional steps would be to write a blog post about it, write it up on reddit's python subreddit, give a talk about it at a conference. Matti On 25/04/2024 23:36, Alexei Lisitsa

Ok, thanks package stand alone I did but how I advertise it? Maybe you as expert can say some thing that is needed , something to develop I want some new experience чт, 25 апр. 2024 г., 23:30 Matti Picus : > On 25/04/2024 23:16, Alexei Lisitsa wrote: > > > Waiting for answer > > > What kind of an

[Numpy-discussion] Re: New feature: binary (arbitrary base) rounding

Hi all, an advantage of sub-byte datatypes is the potential for accelerated computing. For GPUs, int4 is already happening. Or take int1 for example: if one had two arrays of size 64, that would be eight bytes. Now, if one wanted to add those two arrays, one could simply xor them as a uint64 (o

Thanks! That does indeed look like a promising approach! And for sure it would be better to avoid having to reimplement the whole array-part and only focus on the data types. (If successful, my idea of a project would basically solve all the custom numerical types discussed, bfloat16, int2, int4 et
