GRAAL VM

Click Here To Know More About Graal VM

           GraalVM is a high-performance runtime that provide significant improvement in application performance and efficiency which is ideal for microservice. It is designed for applications written in Java, JavaScript, LLVM-based language such as C and C++, and other dynamic languages. It removes the isolation between programming languages and enables interoperability in a shared runtime. It can run either standalone or in the context of OpenJDK, Node.js or Oracle Database.GraalVM can run in the context of OpenJDK to make Java application run faster with a new just-in-time compilation technology. GraalVM takes over the compilation of Java bytecode to machine code. In particular for other JVM-based languages such as Scala.GraalVM is a Java Virtual Machine implementation that address & nbsp;part of the “cold start” problem by doing Ahead-Of-Time (AOT) compilation on JVM-based applications. GraalVM can create a “native image” of your application so that it no longer needs to run inside a JVM environment . This can reduce startup time and in some cases improve overall performance. The native images can also be much smaller than the usual OS + JVM + all  dependency JARs. For example, a recent application I was working on went from a pretty trim 208MB docker image (OS + JVM + deps + app) that started in 2 seconds, down to 14MB and a 0.5s startup time. The Graal name in the GraalVM comes from the GraalVM compiler. GraalVM is one compiler to rule them all, meaning that it’s a single implementation of a compiler written as a library which can be used for many different things. For example we use the GraalVM compiler to compile both ahead-of-time and just-in-time, to compile multipleprogramming languages, and to multiple architectures.One simple way to use GraalVM is to use it as your Java JIT compiler.GraalVM is written in Java, rather than C++ like most other JIT compilers for Java. We think this allows us to improve it more quickly than existing compilers, with powerful new optimisations such as partial escape analysis that aren’t available in the standard JIT compilers for HotSpot. This can make your Java programs run significantly faster.The “Graal” Oracle project started out as a research project inside Oracle Labs, attempting to make a Java compiler while being fast and easy to maintain. The “VM” in “GraalVM” comes from the fact that it runs inside the JVM.The “Graal” Oracle project started out as a research project inside Oracle Labs, attempting to make a Java compiler while being fast and easy to maintain. The “VM” in “GraalVM” comes from the fact that it runs inside the JVM.To run without the GraalVM JIT compiler to compare, I can use the flag -XX:-UseJVMCICompiler. JVMCI is the interface between GraalVM and the JVM. You could also compare against your standard JVM as well.

Combine JavaScript, Java, Ruby, and R

           As well as Java, GraalVM includes new implementations of JavaScript, Ruby, R and Python. These are written using a new language implementation framework called Truffle that makes it possible to implement language interpreters that are both simple and high performance.

 Hotspot is getting old

          The JVM traditionally uses the Hotspot JIT compiler, which is made of 2 compilers:C1 emits simple native code, but which is still faster than executing bytecode in an interpreter, and C2 is a more aggressive compiler that generates better native code based on execution profiles, but it may frequently de-optimize.C2 is the compiler that gives performance, but it is and older, complex code base written in C++. Very few people on this planet have the ability to maintain it.Pricing for GraalVM depends on the edition being used. The Community Edition is open sourced. This edition is built from sources available on GitHub. GraalVM Enterprise is available from Oracle under the Oracle GraalVM OTN License Agreement and under the Oracle Master Licence Agreement. The price of the enterprise edition may vary depending on the license.
