Hello all, I would like to use the gotoblas, as it's more than 30% faster than the blas of the sunperf lib.
So, i compiled gotoblas, with the f90 interface for sun studio. The tests run fine. Then i compiled Lapack. I then got the error in a test program : t at 140277880952688 (l at 15655) signal FPE (Exception en point flottant) in sgemm_kernel at 0x61cd90 0x000000000061cd90: sgemm_kernel+0x3390: mulps %xmm8,%xmm9 dbx: fetch at 0x8 failed -- Erreur d'entr??e/sortie dbx: warning: No frame with source found But, when i'm running the sgemm test program from the lapack blas test, i've got : SGEMM PASSED THE COMPUTATIONAL TESTS ( 17496 CALLS) So it seems that the BLAS is ok !!! I really don't know where to look at. I tried many options for the compiler. With or without optimizations... I succeed in compiling it with gnu fortran (gfortran). But i still would like to use sunstudio with gotoblas. Have you got some ideas of where the problem could be ?
