A cfront-ish approach to templates leads to hellish duplication of

Most of the data the GPU needs is never touched by the CPU, except to move

Yes, AMD's EPYC line and derivatives, with their reasonably nice memory
partitioning is *excellent* for running independent VMs. It does a good
job of letting you scale your core counts appropriately to the size of the
VM.

The hard part is memory consistency.
x86 has a strong coherence model, which means that any write is immediately
visible to any other core that loads the same address. This wreaks havoc
on your cache architecture. You need to either have a global
synchronization point (effectively a global share
Xeon Phi was the last remnant of the first GPU architecture I worked on.
It was evolved from Larrabee, meant to run DX11 graphics workloads.
The first Phi was effectively the Larrabee chip but with the texture
sampling hardware fused off.
The remnants of that work are now living on in the AVX512 in

Not directly. The AVX512 instructions include some significant
permute/shuffle/mask hardware, available on pretty much all instructions.
These in turn lead to very long capacitance chains (ie, transistors in
series that have to stabilize each clock) and so constrain how fast the
clock can run. Fo

I'll take 6912 simple cores at 1Ghz over 192 core at 5GHz any day. So long
as I can spend the 3 months rebuilding the implementation to be cache and
memory friendly.
I love the EPYC line, and have spec'd them into DCs. But for raw compute
it's just not competitive for HPC-like workloads.

Hi,
I was trying to bring up 9front on another machine I have (Lenovo
Thinkstation P620 with a Threadripper Pro 3955WX), and I hang right after
the "boot\n" output of the EFI loader.
Any suggestions on how to debug this? Is there a simple way to just build
the EFI and 9fat partitions on a USB s
boot image too big; will only load the first 2K
Is it normal for 9bootiso to be 6664 bytes long? Or is there something
broken in my source tree?

The multiboot specification says: If bit 16 in the ‘flags’ word is set,
then the fields at offsets 12-28 in the Multiboot header are valid, and the
boot loader should use them instead of the fields in the actual executable
header to calculate where to load the OS image.
I believe they are valid in
