  • of an hour on a 233Mhz K6 and gave the same file size though the byte order is different as expected You re certainly a better C programmer than I as you only use integers and pointers where as I used array references with the occasional floating point operation If you are interested you should submit it to The Prime Pages Your code is faster smaller more understandable and therefore would be easier to impliment than others Have a look at http www smdp freeserve co uk erato cpp for a somewhat faster version should run in 10mins or 11 5 minutes with the file output back in less on a 233Mhz PC Basically it uses bitmaps instead of character arrays and an 8Mb buffer to speed thing up Im sure this could be reduced to less than 2mins runtime 1Mb memory usage if it was hacked a bit further I suppose you could even use a 2D graphics accelerator to make things much faster That would be interesting might even be worth watching tata PG PS I took out the code that output the primes to a file I put them back in to to give me a better timing comparison to other routines I ve run I ve got a lot to learn about C coding tuning I will try Jim s blocking technique and your bitmaps on my 64 bit prime number field routines Thanks to both you and Jim 703CCF9197824E830D9AD423 Content Type text plain charset us ascii name erato cpp Content Transfer Encoding 7bit Content Disposition inline filename erato cpp erato sieve of eratosthenes for up to 2 32 Two steps first find all primes less than 2 16 then use them to sift the remaining numbers in blocks Jim Gillogly 24 Apr 1999 Hacked by

  • else I am forgetting A 1 bit bitmap still has a palette it s usually black and white If you make a new 1bpp bitmap you get black and white automatically You can easily make a two color black white palette and set the bitmap s Palette to it Like you use unit GrayPal interface uses Windows function GetGrayPalette THandle creates and returns a HPALETTE that the caller needs to Delete Object function GetBWXPalette THandle 2 entry palette with entries 0 1 entries 1 0 implementation var GrayColorTable TMaxLogPalette type PBWXLogPalette TBWXLogPalette TBWXLogPalette packed record palVersion Word palNumEntries Word palPalEntry array 0 1 of TPaletteEntry end var BWXColorTable TBWXLogPalette function GetGrayPalette THandle begin result CreatePalette PLogPalette GrayColorTable end function GetBWXPalette THandle begin result CreatePalette PLogPalette BWXColorTable end function MakeGrayPalette TMaxLogPalette var j byte begin with result do begin palVersion 300 palNumEntries 256 for j 0 to 255 do begin with palPalEntry j do begin peRed j peGreen j peBlue j peFlags 0 end end end end function MakeBWXPalette TBWXLogPalette var j byte begin with result do begin palVersion 300 palNumEntries 2 for j 0 to 1 do begin with palPalEntry j do begin peRed 1 j 255 peGreen 1 j
