, ▁the ▁difference ▁here ▁is ▁that ▁expansion ▁produces ▁more ▁memory ▁overhead . ▁The ▁reason ▁for ▁this ▁is ▁that ▁the ▁memory ▁space ▁needed ▁for ▁priv at ization ▁is ▁proportional ▁to ▁the ▁number ▁of ▁process ors , ▁while ▁in ▁expansion , ▁it ' s ▁proportional ▁to ▁the ▁number ▁of ▁loop ▁iterations . ▁As ▁it ▁was ▁previously ▁mentioned , ▁the ▁number ▁of ▁tasks ▁is ▁typically ▁higher ▁than ▁the ▁number ▁of ▁process ors ▁available , ▁which ▁makes ▁memory ▁required ▁here ▁much ▁larger ▁than ▁what ▁is ▁required ▁for ▁priv at ization . ▁ ▁As ▁previously ▁mentioned , ▁changing ▁the ▁scope ▁of ▁parallel ism ▁to ▁explore ▁a ▁different ▁parallel ▁region ▁is ▁also ▁one ▁of ▁the ▁techniques ▁used ▁to ▁enable ▁parallel ization . ▁Ch anging ▁the ▁scope ▁in ▁which ▁the ▁parallel ▁tasks ▁are ▁identified ▁might ▁sometimes ▁greatly ▁change ▁the ▁behavior ▁of ▁the ▁variables . ▁Hence , ▁re anal yz ing ▁the ▁code ▁and ▁performing ▁this ▁technique ▁may ▁often ▁change ▁read / write ▁conflic ting ▁variables ▁into ▁non - conf lic ting . ▁ ▁See ▁also ▁▁ ▁Par allel ▁computing ▁ ▁Open MP ▁ ▁Crit ical ▁section ▁ ▁Loop - level ▁parallel ism ▁ ▁References ▁▁ ▁Category : Comput er ▁programming <0x0A> </s> ▁The ▁Ber ger - G raham ▁House ▁is ▁a ▁historic ▁house ▁at ▁ 1 3 2 7 ▁South ▁Main ▁Street ▁in ▁Jones bor o , ▁Ark ansas . ▁ ▁Situ ated ▁on ▁one ▁of ▁the ▁highest ▁points ▁in ▁the ▁city , ▁this ▁is ▁an ▁impos ing ▁brick ▁structure ▁with ▁Class ical ▁Rev ival ▁and ▁Richard son ian ▁Roman
