streight doubt: so, if kernel not read gmem (only reads @ begin), , uses gmem storage storage only, writing gmem stall warp reading gmem do? background: the kernel sweep across set of partiotioning patterns can predicted , managed. single pattern may use lot of sem , registers calculated , advanced. if statistical value of specific parttern higher previous highest value among processed values in warp, highest value replaced , pattern has saved. kernel carries on evaluationg alternative patterns until end. number of alternative patterns high , necessary recover alternative pattern of highest statistical value @ kernel end , every warp should elect 1 winning pattern (every warp can have own space in gmem) , can keep highest value in register. using more sem store best pattern reduces pattern lenght or number of threads in block, may work to... indeed initial problem little computing in warp call each pattern (poor performance)... thanks in advance

#1 code $row = $result->fetch_assoc()); while ($row) { // code here } #2 code while ($row = $result->fetch_assoc());) { // code here } why #1 code , #2 code give different result? because in #1 execute fetch_assoc() once, while in #2 execute on every loop iteration. in other words, in #2 fetch_assoc() keep on returning rows long there rows available in result set. #1 enter infinite loop if there @ least 1 row available.

i have sevral modules a b c and each module has core module 1 of dependency a+core b+core c+core and i'm supposed package a,b,c in d managed exclude core modules b , c , kept core module in a d |+ a-core |+ b-removed core |+ c-removed core what best thing in situation, bad practise ? you may have more 1 dependency pulls core dependency in d pom.xml so, exclusion not required. important thing here a , b , c depends on same version of core dependency otherwise d packaging include version of core rather one. may compile without error, generate exceptions @ runtime if use of these 2 versions not compatible between them. so focus on using unique version of core in a , b , c . using parent pom or creating dependency aggregating common dependencies tools ease that.
