Re: Nan problems with dgetrf_gpu on RC3
yes this patch is to be applied to strsm too. And the memset for d_x is also going to be in future RC or release. Thanks a lot for the patience and reminder on d_x.

Re: Error from magmablas_dtrsm
I planted a printf in dtrsm so that when magma_dtrsm is called, we know it for sure. This is what I'm seeing so far: du:disco ~/disco-home/sandbox/bugfix> ./nan <- 11:08AM [ [ 0.391137 , 0.37845 , 0.676826 , 0.828647 ]; [ 0.572013 , 1.29715 , 1.72296 , 3.94056 ]; [ 0.382288 , 0.33823 , 1.39019 , 2.5...

Re: Error from magmablas_dtrsm
Hello Katayama,
Could you please give some more details about your running environment? For example, version of CUDA, nvcc, driver, which GPU. Also the exact size of g that causes NaN or wrong result. This so that we could repeat the issue on our side and pinpoint the bug.
thanks!

Re: Error from magmablas_dtrsm
Hi all
We are trying to locate the bug.
First off, could you change NB to different value (a multiple of 16) and see if you still get NaN?
Thanks.
