Hi, Is there any chance that the following code could be optimized? The matrices are not sparse. I wonder whether the fact that the matrix A doesn't change might make it possible to pre-calculate an expression before the loop to avoid the double multiplication in this A*V*A' term. ...
Multiplication with tilingTiling is a technique in which you partition data into equal-sized subsets, which are known as tiles. Three things change when you use tiling.You can create tile_static variables. Access to data in tile_static space can be many times faster than access to data in ...
Lecture2 Memory Hierarchies and Matrix Multiplication Start with single processors… Why? Looking Under the Hood Most applications run at <10% of the “peak” performance Most of the performance is lost on a single processor, moving data Why we care about serial performance? With only using a ...
The matrix is not just a Hollywood movie trilogy, but an exceptionally powerful mathematical tool that greatly simplifies the process of solving one or more equations with variables that have complex relationships with one another(矩阵不像东汉书院那样,是个花花肠子,天天想着多圈点粉丝,完了还想兜售课程...

Ex 1. Proof of identity matrix multiplication: AI=A. As you can see, aiwith non-one coefficient are zeroed-out. Ex 2. Prove when a nxn matrix is invertible, Ax=b exists unique solution for all b belongs to Rn. From the following, we see the uniqueness of solution relies on uniquene...
Matrix multiplication order vs Basis vectors order To introduce even more complication to an already confusing problem let’s introduce the following problem. For example, the 2D coordinate system which we are most familiar with, with basis vectors X,Y{X,Y}X,Y where the XXX axis points to th...
Hi, The following minimal working example reproduces the error. The code computes the Matern kernel and then computes the multiplication of the kernel and the identity matrix. import math import torch import gpytorch from pykeops.torch i...
