Hello there, With the use of CUDA and ptx I managed to make a disassembler for at least one of the nv50 microcode/shader formats. This might come in handy for some people, hence I'm posting it here: http://www.cs.rug.nl/~wladimir/decuda/ I'm not yet sure if pixel/vertex shaders use the same instruction format as the compute shaders used by CUDA, but you'd think so, as nv50 is supposed to have unified shader units. If anyone can help me a bit in finding the shader instructions in valgrind-mmt-extend of mmiotrace dum...

...ast one. That is I want and array [1:65,1:25,1:660] The only way to do this, I know, is tmp.a<-array(dim=dim(a1)[c(2,3,1)]) for(i in 1:dim(a1)[1]) tmp.a[,,i]<-a1[i,,] a1<-tmp.a rm(tmp.a) Is it possible to avoid 'for' loop here? Thank you! --- Best regards, Wladimir mailto:wl at eimb.ru

Hi all, >From a vector, I want to get the unique values and the counts of these unique values in the vector. For example, x<-c(2 ,1 ,2, 1, 4 ,2 ,1, 4 ,1 ,1) xu<-unique(x) xn<-numeric(length(xu)) for (i in 1:length(xu)) {xn[i]<-length(which(x==xu[i]))} There must be a very much simpler method of doing this. Can somebody direct me to the functions that I must read in order to do
