The Boneyard.

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 pictured below [...]

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.

An Inexpensive Machine Park, of Yet-Indeterminate Quality.

Oct. 16 edit: included name of the vendor being evaluated.

Today I had occasion to lease some local rack space in my town. Currently I will not mention the vendor by name here, as I do not yet know the quality of the service, but if it proves satisfactory, will reference the vendor in an appendix [...]

"M" Performance... Pessimizations! or: SSE is a Scam.

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 them in [...]

"M" Performance Optimizations.

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 [...]

"M" Genesis.

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 fraudulently pretends [...]

“Finite Field Arithmetic.” Chapter 19: Peh Tuning and Demo Tapes.

This article is part of a series of hands-on tutorials introducing FFA, or the Finite Field Arithmetic library. FFA differs from the typical “Open Sores” abomination, in that — rather than trusting the author blindly with their lives — prospective users are expected to read and fully understand every single line. In exactly the same [...]
