S38 is out. :-) Comparing

S38 is out. :-)
Comparing akosf's C-37 with some S-38 on his 1,86 GHz Pentium-M it's again alot faster, ratio: 0.61
Let's crunch some S-38 :-)

S38 is 30% faster than C37 on

S38 is 30% faster than C37 on a P3T and 20% faster on a P3. But it doesn't work on a AMD Thunderbird yet:
***UNHANDLED EXCEPTION****
Reason: Illegal Instruction (0xc000001d) at address 0x0040A84E

S38 works fine on the 2 computers I have tried it on. :)

The S38 is SSE optimized, a T-BIRD cannot handle SSE, only MMX. I know this cause I have run the cpu-z app on my own t-bird 1.2 ghz. CPU-z does NOT see the t-bird as SSE capable

Akosf, Just an update on

Akosf,

Just an update on my K6-2's.

One of them appears to be continuing to return invalid results with C37. What's really baking my noodle on this one is these two machines are pretty similiar from a hardware and basic performance viewpoint!

I had expected if there was going to be a problem it would be with the K6/300, but this has really got me scratching my head. I think the next step is to go back to 387 on the malfunctioning one to make sure it hasn't developed a hardware fault.

Unbelievable! My time went

Unbelievable!

My time went from 4 hours on the regular science application to 1 hour ll minutes using S38. That is 30% of the time it used to take my AMD 3500+!

That means the 120 day workload could potentially be reduced to about 36 days (for Windows machines, anyway) if everyone used and got the same efficiencies from S38. Not bad! :D

My Athlon XP 1700+ shows as a T-Bird with CPU-Z. S38 appears not to work on it.

AMD introduced XP 1700+ with three core variation (Palomino, Thorougbred-A and Thoroughbred-B), all of them know SSE.
