Re: Complex types of the MAGMA routines

Malcolm, I don't see any technical reasons. As far as I know they are working on it and would have it soon. My guess is that the reason is combination of man-power needed to do it and priorities. There are many routines to do; others to optimize; maintain them for different platforms; the ones to be...

Re: Complex types of the MAGMA routines

The complex version of the 3 one-sided factorizations will be included. We still don't have some BLAS in complex so if NVIDIA does not provide it until then we are going to provide wrappers for what we need. For example, to do a cherk on the GPU we will just copy the data needed for the operations o...

Re: MAGMA version 0.1 Released

Thanks for trying out MAGMA and the input. The GTX 285 results look impressive! the GPU interface offer better GPU's performance than the same ones in the CPU interface's case (e.g.: sgetrf and sgetrf_gpu). Is that because the time to exchange data between CPU's memory and GPU's memory in the CPU's ...

Re: Multi-GPU support in the future?

Hi Mike, I don't think (correct me if I'm wrong) that complex support is there yet in MAGMA. Presumably this will only increase the number of flops/s since complex arithmetic is more compute intensive? We have the MAGMA routines for complex but not all the complex BLAS that is needed. NVIDIA is work...

Re: Some questions..

Hi, are you going to release compiled binaries for mainly MacOS and Windows systems where CUDA is also supported? If you are not consider adding support for it are you considering releasing as an open source project so still interested users can compiler for that platform? MAGMA version 0.1 is a fre...

Re: Multi-GPU support in the future?

Thanks for your interest in MAGMA! We are planning to support multi-GPU, along with multicore+multi-GPUs. Here are some slides summarizing MAGMA's current work and near future plans. Effect of multi-GPU implementation would be observed on large problems though. If you have for example 4 cards, each ...

Re: MAGMA Roadmap

Yes, we need and welcome any user input. The purpose of starting with a basic version release of MAGMA was to test the level of interest in the library and get as much user feedback as possible. The interest so far has been very high and we plan to quickly extend MAGMA's functionality. Although the ...

Re: OpenCL?

That's an interesting post and I would be happy to see more people commenting on this. We have been thinking about portability issues in MAGMA and we have been monitoring the developments around OpenCL. OpenCL is a standard that many have decided to support. This is great but in my opinion it will t...
