A Java library for accessing NUMA (Non Uniform Memory Access) API.
You can simply use ByteBuffer-like APIs to handle NUMA properties as follows:
// Allocate memory on a NUMA node 1, and the memory is
// automatically collected by GC.
NumaByteBuffer buf = new NumaByteBuffer(16, 1)
// Access data by using ByteBuffer-like APIs
buf.putDouble(1.3, 39L)
buf.putLong(8, 6L)
System.out.println(bb.getDouble(0)) // Print 1.3
System.out.println(bb.getLong(8)) // Print 6
As you imagine, you can directly access primitive NUMA APIs through the NUMA class.
Currenty jnuma supports 64-bit Linux only. For the other operating systems, standard memory allocation in JVM will be used.
If you create a JAR package, you type bin/sbt assembly.
- libnuma (2.0 or higher)
- gcc (glibc 2.5 or higher)
- jdk (1.6 or higher)
