Very Slow Gower Similarity Function
...ould appreciate it. I suspect having a pair of nested for loops is the problem, but I couldn't figure out how to get rid of them. The function is: ### Gower Similarity Matrix### sGow <- function (mat){ OBJ <- nrow(mat) #number of objects MATDESC <- ncol (mat) #number of descriptors MRANGE <- apply (mat,2,max, na.rm=T)-apply (mat,2,min,na.rm=T) #descr ranges DESCRIPT <- 1:MATDESC #descriptor index vector smat <- matrix(1, nrow = OBJ, ncol = OBJ) #'empty' similarity matrix for (i in 1:OBJ){ for (j in i:OBJ){ ##calculate index vector of non-NA descriptors betwe...

[PATCH v2 00/15] Consolidate the mmu notifier interval_tree and locking
From: Jason Gunthorpe <jgg at mellanox.com> 8 of the mmu_notifier using drivers (i915_gem, radeon_mn, umem_odp, hfi1, scif_dma, vhost, gntdev, hmm) drivers are using a common pattern where they only use invalidate_range_start/end and immediately check the invalidating range against some driver data structure to tell if the driver is interested. Half of them use an interval_tree, the others
