Ditto. Very happy with EasyDNS these last 6 years. Had some wierd renewal issue 3 years ago similar to what the OP described but had someone on the phone immediately and the problem was resolved within the hour.

This is precisely a strategy for optimizing away the cost of function calls and other indirection. You basically really want this in any case where you're applying a dynamic expression to a large dataset. We use the technique in Renjin

by bedatadriven 10y ago
This is similar to a technique used in Renjin to compile specific vector computation expressions down to straight-line JVM bytecode, which is then JITed down to machine code. It's a very powerful technique because it removes all the in

This looks pretty nice. Pointer/array arithmetic seems to be handled nicely, (double)malloc(sizeof(double)*100) looks pretty ugly but it's hard to tell what's going on under the DoubleContainer hood. For OSS (or other project

I think this conversation is incomplete without considering the economics of the Mike Palls of the world. Yes, there exist experts who can write hand-tuned assembly that dramatically outperform optimizing compilers. More importantly, a well

Will have to take another look, but it still sounds to me like LLVM IR is more comparable to RTL ( https://gcc.gnu.org/onlinedocs/gccint/RTL.html#RTL ). Gimple variables have types comparable with C types - you get

I should mention that the only problem we have this approach is that neither the AST structure nor the plugin API is guaranteed to be stable between releases, so if you want to use Renjin's full tool chain, you have to be able to insta

by bedatadriven 12y ago
GCC has multiple, rich ASTs that you can access by modifying (and freely distributing) the source, or you can build a plugin that access the AST through the API. The debate hinges on a very subtle point: GCC does not commit to keeping the p

Wow! Terrific. We've needed a resource like this for a long time in the R community, and Hadley is the one to write it!

These are points that need to be addressed for any implementation of R, or any other domain specific language for which numerical guarantees nearly always outweigh performance concerns. GNU R, for example, is implemented in C, and the imple

I think compatibility with GNU R and CRAN is a pretty reasonable goal - even if it's not the focus of this particular Oracle research project. We've been working hard and now systematically to get Renjin (also R on the JVM) to run
