Hello, I modiffied the testing_dgetrf_mgpu.cpp code, to check the correct use of the app. ... // checksum // lapack y magma double max_double = 1073741824; // 2^30 (2^52) double auxl= 0.0; double auxm= 0.0; double res_lap = 0.0; double res_mag = 0.0; double *aux = NULL; double *h_lA[ngpu]; //aux_ldn...

Re: My problem with compiling MAGMA

Hello, I solved the problem. I don't know why or how, two files were modified when I coppied all the folder (to make changes) The files testing_cutil.cpp and testing_sutil.cpp, were corrupted (I didn't change them, ¿wtf?) So, making diff I saw it: diff -r MAGMA_SRC/MAGMA/1.4.1/mkl+cuda60/magma-1.4.1...

Re: My problem with compiling MAGMA

No. The only difference is in this file. I posted the make.inc file before in this post. I don't know why takes errors in files I didn't change. Anyway I will make the diff of the folder and i will tell you which are the results. --------------------- The result of the diff between the folders, one ...

Re: My problem with compiling MAGMA

Hello, I only changed the variable MagmaMaxGPUs from 8 to 12 value, to see if it's possible use more gpus. I recompile my code and I have some errors: ======================================== test ( cd testing && make ) make[1]: se ingresa al directorio `xxx/MAGMA_MGPU/MAGMA_SRC/MAGMA/1.4.1/mkl+cuda...

Re: My problem with compiling MAGMA

Hello,

I'm new with MAGMA.

Is there any document with the different options to compile testing programs in MAGMA? I am making testing times and improvements with multigpus and I want to know if it is possible take better times changing the compiling options.

Thank you so much.

Hello, I have one similar doubt, I don't know exactly which is the difference between the testing programs with _gpu, _mgpu, _m and normal ones. I suppose that _gpu are implemented for compute the algorithm in the gpu, and _mgpu and _m, for multigpus. But I am not sure. I want to know how it works r...
