Phase Change Memory Architecture and the Quest For Scalability
Memory scaling is in jeopardy as charge storage and sensing mechanisms become less reliable for prevalent memory technologies. In contrast, phase change memory...

seL4: Formal Verification of an Operating-System Kernel
We report on the formal, machine-checked verification of the seL4 microkernel from an abstract specification down to its C implementation. We assume correctness...
From Communications of the ACM
Technical Perspective: Learning To Do Program Verification
When you decide to use a piece of software, how do you know it will do what you need it to do? Will it be safe to run? Will it interfere...

Asserting and Checking Determinism For Multithreaded Programs
The trend towards processors with more and more parallel cores is increasing the need for software that can take advantage of...
From Communications of the ACM
Technical Perspective: Building Confidence in Multicore Software
Surprises may be fun in real life, but not so in software. One approach to avoiding surprises in software is to establish its...

Automatic Program Repair With Evolutionary Computation
There are many methods for detecting and mitigating software errors but few generic methods for automatically repairing errors once they are discovered. Recent...
From Communications of the ACM
Technical Perspective: Automated Patching Techniques: The Fix Is In
Finding bugs is technically demanding and yet economically vital. How much more difficult yet valuable would it be to...
