State Accumulation Problem +- Each segment was processed independently without properly restoring accumulated results from previous segments +- The accumulated attention output wasn't being carried forward correctly + +### 2. VKQ Initialization Issue +- The VKQ accumulator was always initialized to zero +- Previous accumulated results from earlier segments weren't being restored +- This caused each segment to start fresh instead of building on previous work + +### 3. Test Logic Problem +- The test was only using the final segment's output +- It wasn't properly accumulating results across all segments during validation + +## Technical Implementation Details + +### State Tensor Format +- **Structure**: `[2, n_heads * q_len]` tensor storing `[M, S]` pairs +- **M**: Maximum KQ value encountered so far (for numerical stability) +- **S**: Sum value for online softmax computation +- **Purpose**: Enables proper continuation of attention computation across segments + +### Key Algorithm Components +- **Online Softmax**: Maintains running maximum and sum across segments +- **State Restoration**: Checks if previous segments exist (`M != -INFINITY && S > 0`) +- **Output Accumulation**: `VKQ_new = prev_output * S_prev + current_segment_contribution` + +## Fixes Applied + +### 1. ops.cpp Modifications +Updated `ggml_compute_forward_flash_attn_ext_f16_with_state` to: +- Check state tensor for previous segment indicators +- Load and scale previous accumulated output by previous sum `S` +- Initialize VKQ accumulator with scaled previous results instead of zeros +- Properly update both accumulated output and state tensor for each segment + +### 2.

Flash attention segmentation requires careful state management between segments +2. The state tensor must properly encode both numerical stability (max values) and accumulation state (sums) +3. VKQ accumulator initialization is critical - must restore previous accumulated results, not start from zero +4.

State Accumulation Problem -- Each segment was processed independently without properly restoring accumulated results from previous segments -- The accumulated attention output wasn't being carried forward correctly - -### 2. VKQ Initialization Issue -- The VKQ accumulator was always initialized to zero -- Previous accumulated results from earlier segments weren't being restored -- This caused each segment to start fresh instead of building on previous work - -### 3. Test Logic Problem -- The test was only using the final segment's output -- It wasn't properly accumulating results across all segments during validation - -## Technical Implementation Details - -### State Tensor Format -- **Structure**: `[2, n_heads * q_len]` tensor storing `[M, S]` pairs -- **M**: Maximum KQ value encountered so far (for numerical stability) -- **S**: Sum value for online softmax computation -- **Purpose**: Enables proper continuation of attention computation across segments - -### Key Algorithm Components -- **Online Softmax**: Maintains running maximum and sum across segments -- **State Restoration**: Checks if previous segments exist (`M != -INFINITY && S > 0`) -- **Output Accumulation**: `VKQ_new = prev_output * S_prev + current_segment_contribution` - -## Fixes Applied - -### 1. ops.cpp Modifications -Updated `ggml_compute_forward_flash_attn_ext_f16_with_state` to: -- Check state tensor for previous segment indicators -- Load and scale previous accumulated output by previous sum `S` -- Initialize VKQ accumulator with scaled previous results instead of zeros -- Properly update both accumulated output and state tensor for each segment - -### 2. Test File Corrections (Attempted) -- Modified test logic to copy accumulated results after each segment -- Changed from using only final segment output to properly accumulating across segments - -## Build System Resolution -Encountered and resolved CMake configuration issues: -- Switched from Ninja to Unix Makefiles generator -- Disabled CURL dependency to avoid missing library issues -- Successfully cleaned and reconfigured build system - -## Current Status -- **Core Algorithm**: Fixed state accumulation logic in ops.cpp -- **Build System**: Successfully configured and compiling -- **Testing**: Implementation ready for validation but final test run pending - -## Key Insights -1. Flash attention segmentation requires careful state management between segments -2. The state tensor must properly encode both numerical stability (max values) and accumulation state (sums) -3. VKQ accumulator initialization is critical - must restore previous accumulated results, not start from zero -4. Test validation must accumulate across all segments, not just use final output - -## Next Steps -1. Run the updated test to verify alignment between standard and segmented flash attention -2. Validate that state accumulation works correctly across multiple segments -3. Performance testing to ensure the state management doesn't significantly impact performance - -## Technical Notes -- Flash attention requires `ggml_flash_attn_ext_set_prec(cur, GGML_PREC_F32)` to trigger F16 computation path -- State management follows online algorithms for numerical stability -- Implementation maintains compatibility with existing flash attention infrastructure \ No newline at end of file diff --git a/test_simple_flash_state b/test_simple_flash_state deleted file mode 100755 index 50686c789bed00194fba7040c6744a3eabc5e503..0000000000000000000000000000000000000000 GIT binary patch literal 0 HcmV?d00001 literal 16856 zcmeHOe{fvIeczKM5XR`v{1h_54{=W9fXH;Pi!eB4O2|ypGLUv?Q^4&6V#w483^t^Y8m1|9GAWJ+l2eF{i&7(?`1<+o z?)UELMMr3-GwmPRn|t5){p|Pq-S2*P-@e`V_TAAH>8|j21gAyf8bRE|#R_TH8E>r9 zCm`*jRn*{Uh~?r8@Rbr%`R$4zS0&$~xwKm21e4x(b-tTkqUD&fheS!QTpBrBN#1+m-+1o4|BR8Xn{N5%r;dhSSe1wmtX;h-5o=7u zlViIYceSoblrQCd>K*RoRom#xpNT3 zkiGfvbIRajW$mY&5oE++fJI+ zE?bGCAX~e-BW~?9SI6d+&04mZ&RB!jy&5WBA$sLGKIulRYL+0Sfm%t3o;UGGw zLpK_YCq>pqlrs<;+!Zy4;>lEDtHN|sCp|e!rk|_NaVT5F^3TN(I9w$lW zC+KrD9vk>~%zg_)U6nWijFJZ<>RURW`0s!7ehhz=;$w}C)y2=EQMVdeWW&Cg_zH18 zcuK|lv0}ycI(6dX`?SUljaRoTfcri3Z(OTz8hdHX;dIo2qu^r7JMg7NREU!f{5%If z>%cE?;Cvm@eTK$)PQ6nWbZA9UbLB%%(FIB>dWaoXp=y$pixci=n+ zpzJ9J?i?>)bl`OV=5)k?U&!DBU5LO!1QsIj|1bhG-b+6W?f!LjXtL_(tAq&MIb~NA zj)ZnUUwu$|TUb*ExUk|99KFli1<8+4&h)WDp)j;p@^qt_eyzmQ4QBee5>Gdl>Ax@W zbVHebsKnEaWcp7^Jl#O1|G31{jbl1f;^~GlJy7E520OjE#M6yqx}(I?4P&~c#M6yp zy1vBI4PyG-5?@1nMTw^y#q@ipi}j@&#PqQuUs!QZK!_pl@=hV+Q&@2dt9K`V!o~l> z#s8a&{}&hkV;6tO#UF6-PrCTWT>M|T_&;~?_q+IeT>M=w{&p9?V-6p@KD1}e!{-R` z40Vj=so)obTY~*t`q1x2^8bi19_sY>3UEf~aHoGeWPEfYyV;O81t>Jx=}&u?R{BG^ zPQNdI5t;^F)Ie|be)Uh$TSB>m!KbJf%0u(1;C?FUX#LgA>U6bxi^)R%6^Kv zp_Dm5s^Q!rvR)nhhgV*H`Q`lOP;g2^*`*N5y^#MH-cwFHnWBR>^?d$eog=G!>S-cm zzBd02nX%1pL~O^uUdnTWpg+Nd4eR%OslXtnuy^;IZA@93WVejKFgr3b`zNd1+ zGqv*B8Sm%uzo9COE<6)NME)YQ`=BS1dq003nO*nB9fv}bWP9=nGKiY1>b$ewyLWS z{I#9A*PxbzT4%1`e`WsnWg*B2O?I_9JN#3s%btLnoAzA2Og0627CPkXo29dbu~1>G zy*ED%3sN|e`vru__tr34tCcQMr$wn1@jgBqygpd4{UJI)|F5A>qEEG>dNA-bQGFd9 z&fkPw-5C2mq~ITr%}re+UjPu9jQD-Br9YsSp!RLT{UAhfBX4x;=Lcb@)ZT~k4@+aR zB_S5h-9=`@lU+^WTz3;_D=4bb)ehPY8UhXFe?}$dPK9%5qQm(VINdu=!$^Kr$tH@w z68?PJ9#RFDRS)^$2db|(Y3-NLT6yF;yH}`Ej&J#UAseB~J-lawC-_6^Mxoua72Z3~ z#9+{q`xW(pR*a-_fz^DxXYwJcWRDsf-uaxop9j6Z%EvI2Y^(g+(C!yJ-u|kWP}+>w zgxZXEDUNgnK0#is%inPX-elRE=BfNSgzs6i10_fY-Bp%#g7q8Epu;Uo==jBII&Q4Y zADNZPH~dcJh`*9lD*bfa=9gCb{nhz!qR?<0xmo_{vNsS%f}&wZqfD` zOe4IjZX?`x&Tk+Jiu|3|Li021g9_|g@(c~S5wv*<%4?3|F5_KABgy?!=&U0*-5lH& zyg7JF&^!qBCt+GTq14}hzfgGRnb2h0fzQ%Kdco^ZJ|J%dQ~B?~r1bHf{XCy)J|51! zdP^vGEVTQrlfC_2%~Q>2^|ogrS-9W}F!7tAfOq*zUO#XvYg+e|CUk_FN1ia^F=nAL)^iE_#t2o!( z&9h5@3uz$&3lUg|z(NH6Pa;51;IZCmo2guL%|$4J;zL7i@Xj)>CL7jDS%YKWxm(F~2g4DU+%;`17*674l%ZbqWE~NS zEf$M=GpRu zmqDK5ONkFBA-#n$`HaYifVbd-l%i32|-Ry3b$buLmmiw}I}1FH(^}B(iJc{|MovuhVUy zcjNyce7%I84|Ui0?ycypsl8`WM~$(kvZJQq?y6u-(_Lo-Yg%`o*;(_TXJgHjCk47_ zd{NCKo>0v`&xV@)o*>X$fL;%*3s{%N!X)`<#p0S)SP9lNz-mWLZAXo-qoz8D)e{n} z=*U-ci{9N+qDNgc)1yTB+ws4>?(~nkJ2#0xthdM0R{i?=m^Dy;Wqm4()3JfEq&)^M z86BmpVS3pHc88V8;-Ul65?I~bxK_zEBPW^}9Esc3pgoo$h3IH(?dtkJLNN_Uht3q-8oE&mm>fVuJT0@di%L|Bus!6bVkzgcFJ8@s!%nP*f9<*ZF!GR@^tN zX0WBbL(aWLWI?NmR=uBv=d=&#`q8|c5>34+@!qE+csNXn@mcLK`~8N>7Fw*hcj;1% zvmBn*%le@>3E_dZ!Hp6uMysl?Kaq?+q+%UUQM@a zn$~ne)4iHLsOdgUr!+mH=}}EjYKqO6GWj$$G;MNjDswyc34C?C%DisFhV@3n7P%@h znpX!}0!@w0>(uI_Wu-k$NR+%oke@y=96Dl244@nLU_eK zzJRoyt2KVqg>TY0U)Ne(SUB-uKWjs~LUgwlUzYeq#p_Px3h@9=s9YW=82_%6zp!{6 zGhWXBgHrxH(Rw*cmgszOcvWVfD`qb%$`1e@&rS zvzNge%HS=)eWFhI+S!7lU&e)K02eNNT^T!D%HYGmms008lwDdwQ`%8R{=PE!qrmHx z>YU??QXcK7gCUjQ;xk|T$0Y78es3e6 zoxoUK8TplEaN5^;ZUshl9v`$rZNSNYcYB4)*x5$%^X&6Z0jG8s?OanuZ!!l%55woe_a`Q(Knc}n*%9q zxQ-6QO*=X)up{0!v+`N0IV88AXXy!QU@)B)5YF0TLqmZ1k$M3}x_K$&8JSj*dgc z!O1=4b3{$Edvma-%k0|NNxSb&Jkm0|LK+NpZWdclUMm zoBhF#NEd08Hl()~w}xX6`23#;m{u%mM^)yh-pg->H(`@|ES@ySveu{Bu0Q`S`#GE9 zi@ws{b-8z5?UJ8^qd~GMa|92u=|cqyGwMsv>KuFSiwf8eFY8Q?#C7e9A3(?q)gAb2 z1X#j%5IXKESf$Se@CAX|%3rijZo(Y|Pn9ju)cA719LQ!F_=K+rl$p{V{$hFR1BN-D z6%>o4o&2Bl<%TrE-%z+d<0uwT`u;(hD*t82+~_#J)ewQ~_^2Hn0JSrUj__GBg==d# zITlD~QfVt=kBdMNlD(iY9uon4KVfCkLJE%H{e}p{#*;9rsGU(c`swQ&#zbDmN<>LP zpQRHvSwtfTa2gm+>60uz775VH4-t?(C6GzUz8L+>+^G$ofprhq6;&v}@5OMY$X{ zz+-dD5oi6+77=wqzEW~h?z<{S9b374J@C -#include -#include -#include -#include -#include -#include -#include -#include - -int main() { - printf("=== Simple Flash Attention State Test ===\n");
