sql - Django complex model - matching events with where clause -


in existing database have table tracking , correlating events , need ideas on how in django. intent query table sets of events occur @ same time. (this used things create scatter-plot graph 1 type of event on x-axis , type of event on y-axis each data point matched time occurred).

the db schema looks this.

table: event eventtime,        eventtype, eventvalue 2017-08-01 10:00, type1,     100 2017-08-01 11:00, type1,     200 2017-08-01 12:00, type1,     300 2017-08-01 10:00, type2,     10 2017-08-01 11:00, type2,     20 2017-08-01 12:00, type2,     30 2017-08-02 14:00, type3,     20 2017-08-02 16:00, type3,     30

a sample query might (yes, ms-access - won't after porting django):

select      xaxis.eventtime xeventtime, xaxis.eventtype xeventtype, xaxis.value xvalue,       yaxis.eventtype yeventtype, yaxis.value yvalue,       event xaxis, event yaxis      xaxis.eventtime = yaxis.eventtime      , xaxis.eventtype='type1' , yaxis.eventtype='type2'      , xaxis.date_hour_utc > #2017-08-01 00:00# , xaxis.date_hour_utc < #2017-08-02 00:00#

with result looking looking this:

xeventtime,       xeventtype, xvalue, yeventtype, yvalue 2017-08-01 10:00, type1,      100,    type2,      10 2017-08-01 11:00, type1,      200,    type2,      20 2017-08-01 12:00, type1,      300,    type2,      30

any suggestions on how accomplish django models? or should run custom query pulls data? know rather complicated question assistance!

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...
