I want to thank @theregister.com for the comprehensive review of the @tenstorrent.bsky.social Blackhole Quiet box. Blackhole is a fascinating bit of kit, and we're hopeful that, over time, our software team can enable and fix all of the very fair points of critique mentioned.

That’s a wrap on #SC25, spending time with so many of my favourite people on the planet. While HPC is known for what it makes, what makes HPC is the community. See you all in Chicago for #SC26. Signing off from Saint Louis #WeAreAllHPCGuru

Glenn Posted his ISC recap, and as always, it's excellent. The exert on Mixed precision and Ozaki did have me giggling whilst reading. I think it's relevant to add some high level context on *why* we vendors decrease FP64; it's not just chasing AI, it's the shear *cost* of FP64. The short ...

Loosing it to this… DO NOT OVERLOAD OPCODES YOU {redacted}

A 25-bit instruction encoding space corresponds to a major opcode in the base and standard
extension encodings.
There are four major opcodes expressly designated for custom extensions Table 75, each of which
represents a 25-bit encoding space. Two of these are reserved for eventual use in the RV128 base
encoding (will be OP-IMM-64 and OP-64), but can be used for non-standard extensions for RV32 and
RV64.
The two major opcodes reserved for RV64 (OP-IMM-32 and OP-32) can also be used for non-standard
extensions to RV32 only.
If an implementation does not require floating-point, then the seven major opcodes reserved for
standard floating-point extensions (LOAD-FP, STORE-FP, MADD, MSUB, NMSUB, NMADD, OP-FP) can
be reused for non-standard extensions. Similarly, the AMO major opcode can be reused if the standard
atomic extensions are not required.
If an implementation does not require instructions longer than 32-bits, then an additional four major
opcodes are available (those marked in gray in Table 75).
The base RV32I encoding uses only 11 major opcodes plus 3 reserved opcodes, leaving up to 18
available for extensions. The base RV64I encoding uses only 13 major opcodes plus 3 reserved
opcodes, leaving up to 16 available for extensions.

Happy place @ the computer history museum!

Really not sure how to square these two images. One implies V length min is 256, the other implies it’s 128. Spec lawyer in me says you go by CPUID

One of the coolest things ever; one of my favorite people in the world, roboticist extraordinaire, and best mate Austin, got me a pair of mugs with the incredible artwork from @mcy.gay!

“You have to choose between optimizing a chip for AI training or AI inference” No, you need to optimize for the workloads you will see, and the ones you expect to see emerge. CNNs have massively different inference requirements than LLMs, which in turn are different from diffusion models.

With the next product launch season fast approaching, a reminder of the first question you should *always* be asking when a figure of merit is presented without context: #HPC

A version of the goose chasing meme with the text changed to read “What type of FLOPS?!?!?”

Call for help #HPC/ #SC / #SC24 : One of the crates for the TexasTech booth never made it to Atlanta; they’re in need of: - AC power strips (preferably with long cords) - A couple of small computers to drive displays - Ethernet cables (at least 20' long) - A small network switch Booth 814

A mastodon post from Alan Sill saying:

If anyone in our #HPC circle of friends at #SC24 can spare a few items to help us out with a missed shipment, we'd appreciate a short-term loan of the following materials for at least a few days until we can get our shipment there:

- AC power strips (preferably with long cords)
- A couple of small computers to drive displays
- Ethernet cables (at least 20' long)
- A small network switch

Again, look for a spare-looking metal frame with some forlorn Texas Tech people at booth 814.
