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 […]

Congratulations to the very first ‘Dulap’ subscriber of my machine rack service! … installed with a colocated customer-owned FG (this service carries no additional charge!) : Thank you for your business!

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 […]

Note: this the second, revised draft of the prospectus, incorporating feedback from prospective customers. The previous draft can be seen here. 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.

Aug. 2020 Update #1: Paginated search; automatic replacement of ancient logger link targets; fix for unicode barf in eat_dump.py. July 2020 Update #3: Automatically skip empty […]

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 […]
