* iq2_kt and iq3_kt work with new int trellis
Much slower than the fp16 based trellis. I guess, Apple doesn't
have int8_t SIMD on the M2-Max GPU.

* This seems slightly faster for IQ2_KT, IQ3_KT TG
* This looks better for iq4_kt TG
* WIP
* Cleanup
* With fancy simd also set func16
* Enable next_128() also on AVX2
Despite having just 16 vector registers it is still faster.

* New iq4_kt trellis
The new trellis generates int8_t values via
sum_as_uint8_t[(ka * idx + kb) & 0x3f33f3f3f] - 126.
CUDA dequantize works.
AVX2 case Ny > 32 works, and we get 273 t/s for L3-8B.
PPL is on par or even slightly lower than original QTIP trellis.
* Something is not working with the AVX2 dot product
* New iq4_kt: CUDA MMVQ
* New iq4_kt: CUDA MMQ
* For now have only iq4_kt use the new trellis
* Fix iq2_kt that got broken along the way
* New iq4_kt: AVX2 dot product finally works
We get 13.6 t/s vs 8.4 t/s with the f16 trellis and f32 arithmetic.
Still somewhat slower than other quants, but no longer pathetic.
* New iq4_kt: fix vanilla AVX2
* New iq4_kt: NEON implementation
We get very respectable PP-512 = 120 t/s.
TG-128 is pathetic at 5.3 t/s, so 20+% slower than the f16 variant.
* New iq4_kt: slightly faster NEON
* New iq4_kt: slightly faster NEON
* New iq4_kt: faster NEON
We are now at 9.4 t/s, up from 6.6 t/s for the f16 trellis.
* Minor
* New iq4_kt trellis: not working Metal implementation
* Remove the extra 4 bytes of row meta data that is no longer used
* Cleanup
* Adding forgottent file
* Switching iq2_kt to new trellis - CUDA MMQ
* New iq2_kt: CUDA GEMV
* New iq2_kt: AVX2 dequantize
* New iq2_kt: AVX2 GEMM/GEMV
* Adding forgotten file
* New iq2_kt: NEON GEMM/GEMV
* New iq2_kt: slightly faster NEON GEMM
* New iq2_kt: Metal - very slow.
It seems Apple Silicon cannot quickly add 4 8-bit ints.
Or I don't know how to do it - but I didn't find anything
in the Metal Shading Language Specification.
So, performance is quite a bit worse than the original trellis.
* Add missing break
* Trying @louiehelm's multiplier
* CPU
* iq3_kt: use integer trellis + CUDA dequantize and MMVQ
* iq3_kt: MMQ
* iq3_kt: AVX2 GEMM
* iq3_kt: AVX2 GEMV
* The trellis quants now need super-blocks of 256, so we need a check

* Repack q4_0 and q8_0 to q8_0_R8
q8_0 is fine, but I observe a very significant PPL increase
for q4_0. Best guess: precision loss with the 32 bit <-> 16 bit
scale conversions.
* Change q8_2_x4 to store in16_t sums
With that q4_0 now works.
I need to check all quants that use q8_2_x4!
* q5_0 and use a dequntizing template
* q6_0
129 t/s -> 296 t/s. q6_0_r4 is at 244 t/s.
* iq4_nl
137 t/s -> 293 t/s. iq4_nl is at 251 t/s.
* q4_1: 135 t/s -> 262 t/s
* q5_1: 125 t/s -> 253 t/s
* iq3_xs
178 t/s -> 363 t/s. iq4_xs_r4 is at 275 t/s.
* q2_K
202 t/s -> 364 t/s. q2_k_r4 is at 247 t/s.

* iq4_ks

* iq4_k
175 t/s -> 353 t/s. iq4_k_r4 is 208 t/s.
PPL is actually lower!
* iq5_ks
180 t/s -> 359 t/s. iq5_ks_r4 is 210 t/s.
PPL is actually lower - 7.4160 vs 7.4494 for LlaMA-3.1-8B-Instruct
* iq5_k - accuracy loss is too big
* iq5_k - there was a bug with the shifts
...and that's why PPL was so high. It is also high on main.
This fixes it.
* iq6_k
148 t/s -> 350 t/s. There is no iq6_k_r4
PPL is actually lower because we have a bug in the existing
implementation!
* iq3_k
169 t/s -> 363 t/s. iq3_k_r4 is at 200 t/s.
* iq2_k
190 t/s -> 364 t/s. iq2_k_r4 is at 232 t/s.

* q6_K dequantizing GEMM
* Much easier: just use different vec_dot types!
* WIP
* Finally q6_K x q8_2_x4 dot product works
* Very slightly better
* We don't need the changes in ggml.c
* Fix AVX2
* iq2_xs
* Fix AVX2
* iq2_s
* q3_K
* Fix q8_k_r8 on Zen4
* q3_K: repack to q8_k_r8 instead of q8_0_r8
With that we hit 360 t/s for LlaMA-3.1-8B on a Ryzen-7950X.
q8_k_r8 is 386 t/s, so for a batch size of 512 repacking costs
~7% of the time taken by the actual GEMM.
* q3_K: don't scale when all quants in a block are <= 127 when repacking
* iq2_s: repack to q8_k_r8 instead of q8_0_r8
* iq2_xs: rapck to q8_k_r8
* WIP
* iq2_xs: repack to q8_k_r8
* iq3_xxs: repack to q8_k_r8
* iq3_s: use q8_k_r8
* iq1_s: repack to q8_k_r8
* iq1_m: repack to q8_k_r8
* iq1_m: slightly faster
* Slightly faster

* q4_K: dequantize to q8_1_r8 for batch >= 32
We get 268 t/s, up from 186 t/s.
* q4_K: GEMM with q8_2_X4
* q5_K: GEMM with q8_2_X4 and repack to q8_1_r8
* Remove the scales, they are not needed

* Much faster iq2_xxs GEMM
PP-512 = 290 t/s vs ~110 t/s (iq2_xxs) or 148 t/s (iq2_xxs_r4) on main.
* iq2_xxs: q8_2_x4 GEMM

* Fix AVX2
* Cleanup
* NEON is not working yet, so still use Q8_K GEMM

* Add RPC backend in device list to override tensors.

* support for models with non-512 aligned tensors
* rpc : do not wait for response when sending RPC_CMD_SET_TENSOR (#12943)
RPC_CMD_SET_TENSOR always returns an empty response and we send this 4
times per token. We can improve TG speed if we don't wait for this empty
response.
The performance impact of this change depends on the network latency.

* fix(rpc): Improve input validation and error handling (#13069)
* fix(rpc): Improve input validation and error handling
The `rpc-server` was vulnerable to Denial of Service attacks via
several RPC commands (`SET_TENSOR`, `GRAPH_COMPUTE`, etc.). Malformed
messages could trigger failed assertions (e.g., invalid `ggml_type`)
or out-of-bounds reads/writes leading to `GGML_ABORT` calls,
crashing the server process.
This PR introduces robust input validation and replaces `abort()`
calls with graceful error handling:
- **Type Validation:** `deserialize_tensor` now checks if the
`tensor->type` is within the valid `GGML_TYPE_COUNT` range
*before* calling `ggml_new_tensor_4d`. Returns `nullptr` on
invalid type.
- **Bounds Checks:** Replaced `GGML_ABORT` in `set_tensor`,
`set_tensor_hash`, and `get_tensor` handlers with error
logging and returning `false` when data/offset parameters
are out of buffer bounds.
- **Size Checks:** Added safe arithmetic checks (for overflow) in
`graph_compute` when calculating required message sizes based
on client-provided `n_nodes` and `n_tensors`. Returns early
if the reported sizes conflict with the actual message size or
would lead to overflow.
- **Error Propagation:**
- `create_node` now checks for `nullptr` return values from
`deserialize_tensor` and its recursive calls, propagating
`nullptr` upwards on failure. Uses `find` instead of `at`
for safer map access.
- `copy_tensor` now checks for `nullptr` from `deserialize_tensor`
and sets the response status to failure if deserialization
or bounds checks fail.
- `graph_compute` now checks for `nullptr` return from
`create_node` and returns failure status correctly. The final
return value now reflects the actual computation status.
These changes improve the RPC server's resilience
against malformed client requests, preventing crashes and ensuring
errors are handled more gracefully.

* refactor(rpc): ambiguous nullptr from create_node
rpc_server::create_node could previously return nullptr if the input ID
was 0 (valid) or if an internal error (deserialization, recursion
failure) occurred (invalid). This ambiguity made error handling
difficult for the caller (`graph_compute`).
This commit clarifies the meaning of nullptr:
- `graph_compute` now checks if the input 'id' was non-zero when
`create_node` returns nullptr, correctly identifying failures
versus intentional null links.
- `create_node` avoids recursive calls for zero IDs and propagates
nullptr unambiguously on failure during recursion.

* refactor(rpc): initial zero check in create_node
The caller (`graph_compute`) already checks `id != 0` when handling
a `nullptr` return from `create_node`, correctly distinguishing
intentional null links from actual errors. This makes the initial
`if (id == 0)` check redundant.
Also removes the log message when a tensor ID is not found in the
provided map which was added in this branch.

Removes the explicit setting of `response.result = GGML_STATUS_FAILED`

* refactor(rpc): remove extra status code setting
Removes the explicit setting of `response.result = GGML_STATUS_FAILED`
when `create_node` returns `nullptr` within `graph_compute`.
Primary signal is the `false` return value in case of failure.

* Experimenting with dequant + f32 GEMM
For iq4_kt this results in a massive PP improvement
from PP512 = ~42 t/s to PP512 = 128 t/s.
* Experimenting with dequant + f32 GEMM
iq2_kt: from PP512 = 57.3 t/s to PP512 = 135.0 t/s
iq3_kt: from PP512 = 43.8 t/s to PP512 = 131.4 t/s

iq2_kt: PP512 = 79 t/s from 42 t/s
iq3_kt: PP512 = 81 t/s from 35 t/s
Also, found the reason why the f16 implementation for iq4_kt was
not working: it overflows. It works after mltiplying with the row scale
before doing the multiply-adds.

* WIP

* WIP
* Testing Trellis quantization
Using 12 bits per 8 weights I get a better rmse than
iq2_xxs. I still need to see how quantizing the group-of-8
scales will affect accuracy. By AVX2 SIMDifying the search
for the best code, LLaMA-3.1-8B gets quantized in 130 seconds
on the Ryzen-7950X CPU - sluggish but still acceptable.
* Testing Trellis quantization: 4-bit quantized block scales
rmse increases by just 3%, so this is beating iq2_xss in terms
of rmse at the same 2.0625 bpw.
* Testing Trellis quantization: playing with scales and generators
* iq2_kt: quantize / dequantize
I now see that I was comparing apples to oranges:
iq2_xxs was using a weight of sigma^2/4 + x^2, while
the Trellis approach wasn't (weight = 1). Once I use the same weight,
iq2_kt is actually slightly worse than iq2_xxs in terms
of rmse, so does not look promising at this point.
Also, once each group of 8 Trellis values no longer has a
constant sum(q^2) that we can precompute, quantization
becomes significantly slower (476 seconds for LLaMA-3.1-8B).
* iq2_kt: CUDA dequantize
so we can run perplexity calcs.
As already indicated by rmse, the 2-bit trellis approach is
quite a bit worse than iq2_xxs.
* WIP
* WIP
* WIP - try larger blocks
With blocks of 32 and 16 bits per groups of 8 the brute force
seach becomes prohibitive in terms of CPU time (30+ minutes
for 8B LLaMA after SIMDifying with AVX2). The trick is to
group the points in clusters, find the nearest cluster,
and only search within the cluster.
* iq2_kt - this is better
Using blocks of 32 and 16 bits per group of 8 weights
it beats iq2_xxs in terms of PPL by a significant margin.
It is 0.0625 bpw larger, but even if we go to 15 bits per
group od 8 (so 0.0625 bpw less than iq2_xxs), PPL is still
lower.
* iq2_kt - even better
Re-quantize after determining block scales
(at the epxense of much longer quantization time).
* iq2_kt: CUDA dot product
Implemented as DMMV.
Very slow - just 81 t/s for LLaMA-3.1-8B.
Then again, Q2_K_S with forced to use DMMV only
gets 112 t/s vs 145 t/s via MMVQ. My memory is that
when the DMMV kernels were properly maintained/used,
DMMV was about on par with MMVQ for k-quants on my GPU.
* iq2_kt: very slightly faster CUDA dot product
* iq2_kt: f16 CUDA dot product
We arrive at 112 t/s.
* iq2_kt: faster f16 CUDA dot product
We arrive at 139 t/s (no FA), and 149 t/s (FA).
My RTX-4080 is ~20% slower than the RTX-6000 quoted in the
QTIP repository, so with FA (which I'm sure they also used)
we are at around ~180 t/s on their GPU, so almost matching
their performance.
* iq2_kt: faster f16 CUDA dot product
We arrive at 146 t/s (no FA), and 158 t/s (FA).
This is measured for LLaMA-3.1-8B with output.weight
left as f16.

* iq3_kt WIP: slowly improving
PPL(LLaMA-3.1-8B-Instruct, 8192) is now 6.8322, which is
starting to be competitive/slightly better than other quants.
* WIP
* iq3_kt WIP: slowly improving
PPL(LLaMA-3.1-8B-Instruct, 8192) is now 6.7892
* iq3_kt WIP: slowly improving
PPL(LLaMA-3.1-8B-Instruct, 8192) is now 6.7689 after shrinking
by 0.015 bpw by using iq4_k instead of q5_k for attn_v.
* iq3_kt WIP: speed up quantization
Nearly 60% improvement of quantization speed by having the
points nelonging to a cluster copied to contiguous memory
during initialization, and then accessed sequantially while
searching for the closest point. LLaMA-3.1-8B now gets
quantized in ~150 seconds on the Ryzen-5975WX.
* iq3_kt speed up quantization
Same trick as last commit applied to iq2_kt. Here we get
an even larger speedup: quantization time on the Ryzen-5975WX
for LLaMA-3.1-8B drops to 195 seconds from 375 seconds!
* iq3_kt: CUDA dot product
* iq2_kt: SOTA
We arrive at
PPL(LLaMA-3.1-8B-Instruct, 8192) = 9.2406
PPL(LLaMA-2-7B, 4096) = 6.4179
* iq2_kt: SOTA
We arrive at
PPL(LLaMA-3.1-8B-Instruct, 8192) = 9.1642
PPL(LLaMA-2-7B, 4096) = 6.3920
* Adding iq4_kt - not competitive at this point
* WIP
* WIP
* iq4_kt: CUDA dot product

PPL(LLaMA-3.1-8B-Instruct, 8192) = 9.0297
PPL(LLaMA-2-7B, 4096) = 6.3913
Ah, quantization is faster too. About 20% faster.
* iq3_kt: small improvements and faster quantization
* iq2_kt: SOTA
We arrive at
PPL(LLaMA-3.1-8B-Instruct, 8192) = 8.9627
PPL(LLaMA-2-7B, 4096) = 6.3825
Quantization is faster too: ~200 seconds for LLaMA-3.1-8B
on Ryzen-5975WX.
* iq3_kt: small progress
* WIP
* iq4_kt: go to 4.0 bpw
15 bits per group of 4, plus 8 bit scales ifor blocks of 32.
This gives a slightly better PPL than iq4_kss.
* iq4_kt: very slightly better
at the expense of much longer quantization time.
* iq4_kt: failed attemt to adjust CUDA dot product
It was working for 4.125 bpw. But after changing to 4.0 bpw
there is something wrong and I don't see the bug.
* DRY
* DRY
* iq4_kt: CUDA dot product works
* DRY
* Report actual bpw
* Minor tweaks
* Checkpoint
Go to groups of 8 for iq3_kt. 2 x 8 = 16 bits for the magnitude
plus 1 bpw for the sign. It goves a visible improvement in the
PPL vs bpw plot, but that comes at the expense of much longer
quantization time (7.5 minutes for LLaMA-3.1-8B on the Ryzen-5975WX).
I also notices that the 3INST generator is not actually generating a
Gaussian distribution. But going to a better generator means
readjusting all the hyper-parameters, so leaving it for later.
