Problem with dsytrd and dsyevd

[Abdelfattah]

Hi,

I'm trying to run the MAGMA test for tridiagonalization (SYTRD) and symmetric eigen values (SYEVD) on double precision. I was running to get results up to 15000 matrix dimension. However, I had a seg fault after 8000 on dsyevd, and after 10000 on dsytrd. It seems this is a memory issue. But I do really extend the runs beyond 10000.

I'm using MAGMA 1.0.0-rc5 and running on Fermi C2070.

You comments are appreciated.

One remedy for the memory issue would be to use a multi-GPU sytrd. Does anyone on the magma team have an idea of when this type of feature will be ready for use?

Thanks,
Jeremiah

For larger matrices you would have to use algorithms supporting multiGPUs. We developed them for the symmetric and general matrices cases and will release them in MAGMA 1.2.

Do you have a features list and estimate of release date for 1.2?

Thanks
