How would I rewrite my code so that I can implement the use of multicore on
an Rstudio server to run regsubsets using the "exhaustive" method? The data
has 1200 variables and 9000 obs so the code has been shortened here:


    model<-regsubsets(price~x + y + z + a + b +  ...., data=sample,
nvmax=500,  method=c("exhaustive"))


Our server is a quad core 7.5 gb ram, is that enough for an equation like
this?
