Re: wishlist

Hi Mark! I need zstedc function, which is absent in Magma. Is it correct implementation: #include "common_magma.h" extern "C" magma_int_t magma_zstedc(char range, magma_int_t n, double* d, double* e, cuDoubleComplex* z, magma_int_t ldz, cuDoubleComplex* work, magma_int_t lwork, double *rwork, magma_...

zhetrd

Hi guys! I work on a program in which I'd like to substitute ZHETRD function with MAGMAF_ZHETRD. After substitution I got error message with information that parameter 9 is invalid (length of work array). LAPACK documentation says LWORK is INTEGER The dimension of the array WORK. LWORK >= 1. For opt...

Re: Compilation of MAGMA with PGI for CUDA F

Hi! I faced with the same problem. I failed to compile MAGMA with PGI. it looks like you have to compile MAGMA with GNU compiler tools and write an appropriate interfaces for them http://www.pgroup.com/lit/articles/insider/v3n1a5.htm http://icl.cs.utk.edu/magma/forum/viewtopic.php?f=2&t=249 http://i...

Re: magma_dsytrd questions

Hi! I'm a little bit confused about performance results on the first page. In my task I substituted LAPACK function with MAGMA one: #ifdef MAGMA CALL MAGMAF_DSYTRD( UPLO, N, A, LDA, W, WORK(INDE), WORK(INDTAU), $ Z, LLWORK, IINFO ) #else CALL DSYTRD( UPLO, N, A, LDA, W, WORK(INDE), WORK(INDTAU), $ Z...
