hi Antonio, The name's Sachin :) . I need this because im not implementing the ATLAS, fast BLAS or anything like that. What im trying to do is to make a GPU version of blas. I have implemented this so far but extremely inefficiently. What i need to do is to do things like initialisation of the GPU hardware as soon as Rblas.dll gets loaded.
Whats happening so far is something like this: GPU_DGEMM (arguments)}/*this is a blas function*/ initialise_GPU; /*rest of code*/ return; } sorry for not being clear sachin Antonio, Fabio Di Narzo wrote: > > hi, whoever you are (I've seen no signature), > > 2009/1/22 sachin1234 <sachinthaka.abeyward...@csiro.au>: >> >> hi everyone, >> >> Im implementing a new RBlas dll but just for optimising sake i need to >> know >> how and WHERE (which source code) RBlas gets loaded. there is a call to >> loadlibrary() in dynload.c BUT it seems this is not the function that is >> loading Rblas. > > Why do you need this?
