oracle - Sum Every N Records SQL -


i have query, returns (right below 'query results') grouped date(varchar), , values. vehicles have passed toll plazas.

select substr(cab_momento,1,12), sum(case when comvsauto = '1' , nome in ('sul','oeste') 1 else 0 end)  sul_oeste_auto, sum(case when comvsauto = '0' , nome in ('sul','oeste') 1 else 0 end)  sul_oeste_com, sum(case when comvsauto = '1' , nome in ('norte','leste') 1 else 0  end) norte_leste_auto, sum(case when comvsauto = '0' , nome in ('norte','leste') 1 else 0  end) norte_leste_com (select a.idtransaccion, a.cab_momento, a.cab_via, a.comvsauto, b.nome (select idtransaccion, cab_momento, cab_via, cab_estacion estacion, case ctl_clase when '01' 1 when '07' 1 when '08' 1 else 0 end comvsauto usrhost.atransaccion cab_momento > '20170818000000') inner join (select sen.estacion estacion, via.via via, sen.nome nome  usrhost.aestacion_sentido sen inner join usrhost.avia via on sen.estacion = via.estacion , substr(via.via,3,1) = sen.sentido order 1,2) b on b.via = a.cab_via , b.estacion = a.estacion) group substr(cab_momento,1,12) order 1

i need sum every 15 minutes (1st column).

for example: minute x minute y - 1231 | 12314 | 1241 | 21415 minute x+15 minute y+15 - 1111 | 13344 | 1345 | 22455 ...

thank in advance

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
