Re^9: Performance goes upwards!

Alex Granovsky


glad to know that!

00400 means simply 400 i.e. leading zeros do not affect the value.

I'd suggest you to check the sequence I have suggested - i.e.,
the consequent powers of two: 512, 1024, 2048, etc...

>I was mistaken in arithmetics! Performance appeared much better! Now I have for 16, 24, 32 cores performance about 165, 244, 312%. I've made runs with unknown to me (but not for FF) values mxgsum=00400, 00800, 001000, 004000. In all these runs results rather close. What these values (00400 etc) means in my case?

>>Hi, Alex,
>>I've edit my previous post and insert first results (before your post has appeared on page) - but with wrong number 00400 (as I've learnt now from your post). I've tried to run FF with mxgsum=0x400 however FF wrote that he doesn't understand what is means. Then I put mxgsum=00400
