This makes multi-threading possible with algorithms that aren't inherently parallel (such as LZMA). There's also a central index of the sizes of the blocks, which makes it possible to do limited random-access reading with granularity of the block size. =EE=CF =D1 =C2=D9 =CE=C5 =D3=CF=D7=C5=D4=CF=D7=C1=CC =CF=C2=CF=CC=D8=DD=C1= =D4=D8=D3=D1 =CE=C1 =DC=D4=D5 =D4=C5=CD=D5. =EB=C1=CB =D0=CF=C9=D3=CB =D0= =CF =D3=CC=CF=D7=C1=D2=C0, =D4=C1=CB =C9 =DE=C1=D3=D4=CF=D4=CE=CF=C5 =CB=CF=C4=C9=D2=CF=D7=C1=CE=C9=C5= -- =DC=D4=CF =D0=CF =D3=D5=D4=C9 =CF=DE=C5=CE=D8 =C9=CE=CB=D2=C5=CD=C5=CE= =D4=CE=D9=C5 =C1=CC=C7=CF=D2=C9=D4=CD=D9, =C9 =CE=C9=DE=C5=C7=CF =D2=C1=D3=D0=C1=D2=C1=CC=CC=C5=CC=C9=D4=D8 =DA=C4=C5= =D3=D8 =CE=C1 =D3=C1=CD=CF=CD =C4=C5=CC=C5 =CE=C5=CC=D8=DA=D1. =F2=C1=D3= =D0=C1=D2=C1=CC=CC=C5=CC=C9=D7=C1=CE=C9=C5 =C4=CF=D3=D4=C9=C7=C1=C5=D4=D3=D1 =DA=C1 =D3=DE=A3=D4 "independent blocks",= =C1 =DC=D4=CF =D5=C8=D5=C4=DB=C1=C5=D4 =D3=D6=C1=D4=C9=C5. =F4=CF =C5=D3=D4=D8 =D0=CF=D2=D5=C2=C9=CC=C9 =C6=C1=CA=CC =CE=C1 =CB=D5=D3= =CB=C9 =C9 =C4=C1=D7=C1=CA =D3=D6=C9=CD=C1=D4=D8 =D0=CF =CB=D5=D3=CB=C1=CD.= =F0=D2=C9 =DC=D4=CF=CD =D3=C8=CF=C4=D3=D4=D7=CF =CD=C5=D6=C4=D5 =CB=D5=D3=CB=C1=CD=C9 =D5=D6=C5 = =CE=C9=CB=C1=CB =D5=DE=C5=D3=D4=D8 =CE=C5=CC=D8=DA=D1. =E1 =C9=CE=CB=D2=C5= =CD=C5=CE=D4=CE=CF=C5 "=D3=CB=CF=CC=D8=DA=D1=DD=C5=C5 =CF=CB=CE=CF" =D5=CC=C1=D7=CC=C9=D7=C1=C5= =D4 =DC=D4=CF =D3=C8=CF=C4=D3=D4=D7=CF =CF=DE=C5=CE=D8 =C8=CF=D2=CF=DB=CF. --yh423QPMiEk4ZruG Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkhaaUsACgkQfBKgtDjnu0YGpgCfSGpFHFmUxi57OqSFXGIp03yg IKQAn1wQNWLAZ8heN2bpWlv6tJkA+Qza =BKPM -----END PGP SIGNATURE----- --yh423QPMiEk4ZruG--
