compiled msieve on PS3
 

hi all,

i just want to announce i successfully compiled msieve on the
playstation3 (on yellow-dog linux)

using a single PPE i got a 272 bits number factored in 37 mins
(its not canned heat but its ok)

for compiling you have to fix the file dd.h (because no ppc_intrinsics.h on PS3)

starting at:

#if defined(__GNUC__) && (defined(__powerpc__) || defined(__ppc64__))

//#include <ppc_intrinsics.h>

/*
* fmsub - Floating Multiply-Subract (Double-Precision)
*
* (a * c - b) double precision
*/
static inline double __fmsub (double a, double c, double b) __attribute__((always_inline));
static inline double
__fmsub (double a, double c, double b)
{
double result;
__asm__ ("fmsub %0, %1, %2, %3"
/* outputs: */ : "=f" (result)
/* inputs: */ : "f" (a), "f" (c), "f" (b));
return result;
}

regards

Very cool. Just to be pedantic, the compiled binary would not be using the special Cell processing engines everybody is drooling over, but rather the 64-bit PowerPC core. Once in a while I think about what it would take to make sieving SIMD-friendly, but any of the ideas I get would require major code transformations to even test.

haha :-)

hey - we got the toy for 3 days now in ancient europe :-)
so first tests with the spe's are made - i also don't expect fast progress
but some stuff is already working with spe support
(coded some RC4 code running on SPE's :-)
