Rack Service Launch.

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 in [...]

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 [...]

TMSR North Ameristan Rack Prospectus: Initial Draft.

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.

Logotron Genesis.

Warning: If you reached this page from anywhere other than loper-os.org or my IRC logger site, please do not send me bug reports. Chances are that you were looking at a hostile fork of this program. All questions pertaining to such ought to be addressed to the maintainers of those forks.

"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.

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 to do.

To keep [...]

“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 [...]

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.

25 Years of Loud, Expensive Space Heaters.

A half-written draft of this piece has been living on my HDD for nearly half a year. Recent discussions re: the subject of “aging and death of PC irons” prompted me to dust it off and quickly post. Regularly-scheduled programming will resume shortly…
