Re: MAGMA 2.5.1 compilation problem on windows

Hello, I compiled with NMake. I broke the command to compile magma_intermediate_link.obj in two new objects magma_intermediate_link1.obj and magma_intermediate_link2.obj and them added both the the compilation of the magma.lib.

LOBPCG single precision fails to converge for most problems

Hello, I have been testing the LOBPCG. On double precision, it works fine. On single precision, it seems quite sensitive.

When doing the device linking of the object magma_intermediate_link.obj, NVCC sends an error "command line is too long". I saw this is a problem with cmake deals with CUDA long commands...
