Xv6, a simple Unix-like teaching operating system Introduction Xv6 is a teaching operating system developed in the summer of 2006 for MIT's operating systems course, 6.828: Operating System Engineering. In 2019, we ported xv6 to RISC-V for a new undergraduate class 6.S081. Xv6 sources and text The latest xv6 source and text are available via git clone git://github.com/mit-pdos/xv6-riscv.git and gi

Project overview Biscuit is a monolithic, POSIX-subset operating system kernel in Go for x86-64 CPUs. We wrote it to study the performance trade-offs of using a high-level language with garbage collection to implement a kernel with a common style of architecture.

6.828 teaches the fundamentals of engineering operating systems. You will study, in detail, virtual memory, kernel and user mode, system calls, threads, context switches, interrupts, interprocess communication, coordination of concurrent activities, and the interface between software and hardware. Most importantly, you will study the interactions between these concepts, and how to manage the compl

We at PDOS build and investigate software systems for parallel and distributed environments, and have conducted research in systems verification, operating systems, multi-core scalability, security, networking, mobile computing, language and compiler design, and systems architecture. PDOS builds high-performance, reliable, and working systems. We are part of MIT CSAIL. See our publications for mor

About SCIgen is a program that generates random Computer Science research papers, including graphs, figures, and citations. It uses a hand-written context-free grammar to form all elements of the papers. Our aim here is to maximize amusement, rather than coherence. One useful purpose for such a program is to auto-generate submissions to conferences that you suspect might have very low submission s

We build and investigate software systems for multicore computers. We have analyzed and fixed scalability problems in existing software, such as the Linux kernel, and built scalable software from scratch, such as RadixVM and the Corey kernel. To facilitate this work and help identify scalability bottlenecks on multicore computers we have built analysis tools, like DProf. Current Projects The Scala
