Jerome Robert	1a1935507b	[z]ger: increase multithread threshold The ones given in `3ae30cd` was by far to low because I mixed m and m*n in my measures. Note that the new ones are closed to the [z]gemv ones which is comforting that both are right.	9 years ago

Jerome Robert	b17ccb4c5c	Fix a segfault in gemv when MAX_STACK_ALLOC is set * stack_alloc_size is needed after the implementation call but it may be overwritten if it's optimized to a register, because some gemv implementation (ex: dgemv_n.S) do not restore all register (ex: r10). * do the same in ger.c for the same reasons even if the bug has not been observed.	10 years ago
Jerome Robert	e9d9a8eae3	Allow to do gemv and ger buffer allocation on the stack ger and gemv call blas_memory_alloc/free which in their turn call blas_lock. blas_lock create thread contention when matrices are small and the number of thread is high enough. We avoid call blas_memory_alloc by replacing it with stack allocation. This can be enabled with: make -DMAX_STACK_ALLOC=2048 The given size (in byte) must be high enough to avoid thread contention and small enough to avoid stack overflow. Fix #478	10 years ago
