Comment (by fbissey):
Not sure what happened I wanted to do another run to post tuning.c but the
value of ZNP_mpn_smp_kara_thresh is now 133. I swear it was SIZE_MAX
before. There is still plenty of SIZE_MAX value in the file:
{{{
#include "zn_poly_internal.h"
size_t ZNP_mpn_smp_kara_thresh = 133;
size_t ZNP_mpn_mulmid_fallback_thresh = 4868;
tuning_info_t tuning_info[] =
{
{ // bits = 0
},
{ // bits = 1
},
{ // bits = 2
94, // KS1 -> KS2 multiplication threshold
SIZE_MAX, // KS2 -> KS4 multiplication threshold
SIZE_MAX, // KS4 -> FFT multiplication threshold
270, // KS1 -> KS2 squaring threshold
SIZE_MAX, // KS2 -> KS4 squaring threshold
SIZE_MAX, // KS4 -> FFT squaring threshold
206, // KS1 -> KS2 middle product threshold
SIZE_MAX, // KS2 -> KS4 middle product threshold
SIZE_MAX, // KS4 -> FFT middle product threshold
1000, // nussbaumer multiplication threshold
1000 // nussbaumer squaring threshold
},
{ // bits = 3
105, // KS1 -> KS2 multiplication threshold
SIZE_MAX, // KS2 -> KS4 multiplication threshold
SIZE_MAX, // KS4 -> FFT multiplication threshold
270, // KS1 -> KS2 squaring threshold
9634, // KS2 -> KS4 squaring threshold
SIZE_MAX, // KS4 -> FFT squaring threshold
120, // KS1 -> KS2 middle product threshold
SIZE_MAX, // KS2 -> KS4 middle product threshold
SIZE_MAX, // KS4 -> FFT middle product threshold
1000, // nussbaumer multiplication threshold
1000 // nussbaumer squaring threshold
},
{ // bits = 4
123, // KS1 -> KS2 multiplication threshold
SIZE_MAX, // KS2 -> KS4 multiplication threshold
SIZE_MAX, // KS4 -> FFT multiplication threshold
154, // KS1 -> KS2 squaring threshold
SIZE_MAX, // KS2 -> KS4 squaring threshold
SIZE_MAX, // KS4 -> FFT squaring threshold
132, // KS1 -> KS2 middle product threshold
