[jira] [Created] (IGNITE-1497) Support CPU architectures different
from x86/x64
Denis Magda created IGNITE-1497:
-----------------------------------
Summary: Support CPU architectures different from x86/x64
Key: IGNITE-1497
URL: https://issues.apache.org/jira/browse/IGNITE-1497
Project: Ignite
Issue Type: Improvement
Components: general
Reporter: Denis Magda
Ignite widely uses {{Unsafe}} instance throughout the code and the usage is mostly based on the fact that the platform will be running on a little-endian x86/x64 machine.
As an example the following classes work with short, int, long and other type values bigger than 1 byte in size without taking CPU endiannes into account:
- {{DirectByteBufferStream}};
- {{PortableObjectOffheapImpl}};
- {{GridUnsafeDataOutput}};
- etc.
This leads to VM crashes on different CPU architectures:
- IGNITE-1493;
- http://stackoverflow.com/questions/32592881/apache-ignite-arm-unsafe-getfloat-segmentation-fault
All the classes that use {{Unsafe}} in Ignite have to be revisited and modified in a way to support different CPU architectures.
