IBM open sources its A2O POWER processor core through the OpenPOWER Foundation

The A2O core is an out-of-order, multi-threaded, 64-bit POWER ISA core that was developed as a processor for customization and embedded use in system-on-chip (SoC) devices. It’s most suitable for single thread performance optimization. A follow-up to its parent high-streaming throughput A2I predecessor, it maintains the same modular design approach...

Researchers demonstrate in-chip water cooling

As desktop processors were first crossing the Gigahertz level, it seemed for a while that there was nowhere to go but up. But clock speed progress eventually ground to a halt, not because of anything to do with the speed itself but rather because of the power requirements and the heat all that power generated. Even with the now-common fans and massive...

Non-POSIX file systems

Operating systems and file systems have traditionally been developed hand in hand. They impose mutual constraints on each other. Today we have two major leaders in file system semantics: Windows and POSIX. They are very close to each other when compared to the full set of possibilities. Interesting things happened before POSIX monopolized file system semantics.When...
