GraalVM: Run Programs Faster Anywhere

Didn't know about this. Can you point me to some references that list the tradeoffs?

You can check libraries here: http://www.graalvm.org/docs/reference-manual/compatibility/

We don't test all of them but many.

We have considered .NET support but we are not actively working on it right now. But GraalVM is an open platform. Everyone can develop a language for it: http://www.graalvm.org/docs/graalvm-as-a-platform/

Is anyone else so leery of Oracle's lawyers you want nothing to do with this? Even if it's awesome work, as I expect it is, I don't trust Oracle not to someday find a new way to screw me, whatever the text of the license.

(I'm having doubts if this comment belongs here. But it's my genuine reaction, for what it's worth.)

On the "why graal" page, it says that one benefit is you can use a larger heap size for nodejs applications. I would imagine one other big benefit is that you can have true multithreading since the app now runs on the jvm. Is this indeed possible? Is there any guidance on how to do it? Rhino had the concepts of Scope's and Context's to somewhat safely parallelize code, so curious if there are similar primitives in Graal?

I have been paying some scant attention to GraalVM for some time, having been excited by "universal VMs" for decades now (including setups like LLVM, which most people forget was designed as a JIT-compiled VM, despite that being in the name), and I develop Cycript (which is somewhat the "opposite" technology, binding together existing virtual machines all into the same process space and doing crazy interop; though I haven't done a public release now in well over a year).

I am excited to see such a beast coming from a major company with a strong track record in VMs, and particularly given that it is based on their existing JDK, and am particularly excited that it now seems to be available!

I have some questions that I did not managed to easily get answered from looking over the website.

Can I AOT with this (via SubstrateVM) and deploy to "mobile" targets, and specifically iOS?

Are there any examples of embedding GraalVM in an existing native application (such as the noted idea of having GraalVM accessible inside of MySQL)?

Is there an existing embedding for node.js? (I don't mean "can I run node.js apps on GraalVM?"; I mean: from node.js, can I instantiate a GraalVM and give it code to execute in a new context, or will I need to build my own bindings to the GraalVM embedding API for that first?)

I did find some documentation for using an embedded GraalVM in a Java application, but while I work on many projects in many languages, none of them have been written in Java now for over a decade. I guess I was expecting a C/C++ API to be documented somewhere, not a Java API (due to the listed prototypical embeddings, and based on my long experience with embedding other virtual machines, including the Oracle/Sun JVM).
