Problem Statement
When I run the command on my local machine, I observe a noticeable performance boost as the number of threads increases.
However, on Setonix, regardless of whether I specify 1 or 128 threads, the performance remains consistently sl...
It can be done. XB,XC contain all the information of the matrix X, and the same for Y.
So you can get whatever you need from those matrix.
I would suggest you to reverse thinking, from what to be calculated to what can be used.
It is something like putt...
Multiplication of XC XB YC YB does not seem to work
Hi - I might just be being a dumbass, but, it doesn't seem mathematically possible to convert the matrices XC XB YC YB into the value that is found by doing the multiplication of X and Y.
If anyone ...
The project mentions to write the results for the B and C matrices to different file.
I am confused what it means the final results for B and C.
for example, I have three pair X1,Y1; X2,Y2; X3,Y3;
for pair1 I have X1B X1C, Y1B,Y1C; for pair2...
and I ...
The project said there should be two consective zero in B and C
if A has no non-zero elements.
But what's the point of that? Since for B it only contains non-zero elements,
that simply means all the zero are used for representing null.
So one zero is ...
I would say for N 100000 , it is more efficient to store the result in an uncompressed form. When N is large, even if the original matrix has a low non-zero rate, the resulting matrix is likely to have a non-zero rate close to 1 .
Hi Professor,
If we have a matrix A with N rows and N columns, we can compress it into two new matrices, AX and AY , each with N rows and M columns. The problem is, we don t know what M is when allocating memory for ...
Hi,
It says on the unit outline that the mid semester test is on the 11th of September. Is that correct?
I only ask since often there tends to be inconsistencies with the dates on the unit outline, and the actual dates.
Thanks

I just checked your code and confirmed that I have the same result.
Yes, this behavior is pretty standard.
When using more threads, we must consider the cost of thread creation and deletion, data distribution, memory access, etc. Using...

I have four questions
1. For the dimensions of matrices B and C, are we assuming that the number of columns is fixed to be two? If not, would that mean a zero-element row in the original matrix would get a full row of zeroes in B and C (i.e. if I hav...
