Re: Multiple queues and sgemv_batched

So it really doesn't matter for these sizes. Thank you for your thorough reply, really helps to know specific numbers.

Re: Toeplitz Matrix Batch

My specific problem is a batch of 16000 equations, all of which have the same A matrix, but different b matrices. Also its a symmetric, dense matrix.

Toeplitz Matrix Batch

Hello I have to solve a batch of several (16000) equations AX=B where A is a Toeplitz Matrix . Which of the solvers in Magma is more suitable for a problem like this (apart from gesv that seems generic)? (For anyone who might not know, a Toeplitz matrix is one comprised solely of diagonals) Kind reg...

Multiple queues and sgemv_batched

Hello I have a problem where i have to call 9 different sgemv_batched calls, on completely different data, save for the batch of A arrays, which is really the same matrix over and over. So i thought i could parallelize the bunch by creating 9 different queues and assigning each queue to one batched ...

Re: Batched GEMV with float4

To clarify, do i break up my float4 into 4 gemvs OR use gemm with a 4 column matrix?

Cant see posts and cant contact people

I know this doesnt concern MAGMA but its currently the only way i can see how to contact someone, as my PMs are disabled. I have tried to post twice on this forum and neither can see my posts nor have received any feedback for them. Could someone please respond as to why those things happen? Is it a...

Batched GEMV with float4

I want to use batched GEMV with a vector of float4 elements. However, I am ambivalent about how to proceed- do I break my float4 and do the gemv four times and then reassemble tem, or just write the size of float4 as inc and it will sort itself out?



Kind regards
