Congratulations to the first paying subscriber of my machine rack service! Thank you for your business.

Note: this the third and final draft of the machine colocation rack costs sheet and service terms. Prices have not changed since the last revision. The service is now live. Rack space, as described below, is immediately and henceforth available exclusively to my L1 and L2 WoT (presently visible here.) If you, reader, are not […]

Update: As of 26 Nov 2019, all of the auction items in my boneyard have been sold and sent to their purchasers. I have been asked to catalogue certain contents of my machine boneyard which are due to change hands on account of imminent liquidations of two operations in which I took part. The items […]

I have provisioned a machine colocation rack for the exclusive use of The Most Serene Republic, as represented by the WoT L1 and L2. If you, reader, are not in this roster, you may […]

Edit (27 Oct 2019) : This document is supplanted by the second draft of the prospectus. I have provisioned a machine colocation rack for the exclusive use of The Most Serene Republic, as represented by the WoT L1 and L2. If you, reader, are not in this roster, you may safely skip this article.

This article is a continuation of the M series. The vpatch given below entirely re-implements the TLB (MMU) of M to use SIMD instructions from the AMD64 SSE2 set. Whereas previously TLB entries were kept in memory and searched iteratively, now we keep the Tags (3 byte each) sliced into three XMM registers, and search […]

This article is a continuation of the M series. The vpatch given below speeds up the execution of M by approximately 30% (as measured by the Dhrystone benchmark.) It implements separate single-entry TLB caches for reads and writes; a set of fastpath exception handlers; and several other minor optimizations. You will need: A Keccak-based VTron […]

Current Table of Contents: M is a MIPS-III system emulator, written purely in AMD64 assembly to make optimal use of commonplace iron. As discussed previously. M will run lightly-modified Linux kernels with strict logical isolation vs. the host (and vs. any other instances of itself.) That is, it in fact does exactly what e.g. QEMU […]
