Law-abiding hardware and

• perating system trends

■ User Space APIs are not enough ■ Accelerating OS functionality

• vs. Kernel API vs. transparent usage

■ PTasks, GPUStore, Gdev framework, … ■ IBM CAPI, ARM, …

Rack-Scale Resource Management

■ Data-Center Trend: High density of SoCs incorporated with few HEs of rackspace ■ SoCs may contain both general purpose and special purpose units ■ General purpose units may vary in type (performance/power/…) ■ Using high-speed interconnects, logical machines can be formed in accordance to specific workloads
