Revision Author Date Message Commit Date
c995994 Amit Agarwal 11 December 2015, 19:38:56 UTC Fixed a bug in device selection enforcement. The enforcement function was file static instead of global due to which each source file was getting its own copy of the function and the static variable inside it. 11 December 2015, 19:48:04 UTC

f5b6f0e Mark Hillebrand 10 December 2015, 15:07:21 UTC Scripts/build-and-test: for "--target cpu" also do CPU-only build on Linux CPU-only build output will go the build/cpu/{debug,release} directories. Note: test and clean-after functionality needs to be adapted in future changes. 11 December 2015, 10:45:13 UTC
29cd86e Amit Agarwal 11 December 2015, 10:20:00 UTC Implemented sharing of node output value matrices sharing which hugely reduces the amount of GPU memory required for evaluating/training a CNTK model. Currently this feature is off by default and needs to be enabled through a boolean config setting named shareNodeValueMatrices. After this feature has been tested more throughly, this will be turned on by default 11 December 2015, 10:20:00 UTC

17cd7a8 Frank Seide 10 December 2015, 09:25:16 UTC Merge branch 'fseide/network' of https://git.codeplex.com/cntk into fseide/network 10 December 2015, 09:25:16 UTC
c0d4e86 Frank Seide 10 December 2015, 09:24:36 UTC towards implementing MBLayout not as dense bits but an explicit set of sequences (which will be needed for sequence-to-sequence, and woiuld also make fix DelayedValueBase for m_timeStep > 1): flags can now ONLY be set through AddSequence() or AddGap(), i.e. in full sequences (MBLayout::Set() is now private, and SetWithourOr() and Mask() are commented out); HTKMLFReader and LUSequenceReader have been modified to follow the new method (also heavily commented that code); BatchSequenceReader (LMSequenceReader project) not so much: It did not set end or gap flags, so it could not be fixed (and likely did not work before this change, either). Instead, it now throws at those places; EvalReader did not maintain the needed state, so the fix will have incorrectness for DelayedValueNodes with m_timeStep > 1; RecurrentNode currently disabled for m_timeStep > 1, as that will be fixed very differently once this is complete; DecimateMinibatch() temporarily disabled. We need a new method in MBLayout to support this 10 December 2015, 09:24:36 UTC
7b08e39 Frank Seide 10 December 2015, 04:37:48 UTC (comment) 10 December 2015, 04:37:48 UTC
780b9ee Frank Seide 10 December 2015, 01:53:26 UTC MBLayout::AddSequence() now also remembers per-sequence distance to boundaries 10 December 2015, 01:53:26 UTC
6755d97 Frank Seide 10 December 2015, 01:29:04 UTC added a workaround for a bug in distributed reading (returning an inconsistent MBLayout at end of epoch), which the recenly fixed to GetNumSamplesWithLabel() to return a wrong value (the old version returned the right value out of pure luck); deleted unused function ComputationNetwork::SetNodeValue(); added some code to MBLayout::AddSequence() w.r.t moving a way from the bit masks 10 December 2015, 01:29:04 UTC
b0c1156 Yongqiang Wang 10 December 2015, 01:10:09 UTC Add support of subminibatch for sequence training. 10 December 2015, 01:10:09 UTC

799f9ed Frank Seide 10 December 2015, 00:25:25 UTC (brought back old GetNumSamplesWithLabel() to see where it differs in Jenkins) 10 December 2015, 00:25:25 UTC
9ea21ab Frank Seide 09 December 2015, 23:59:25 UTC clarified and enforced the contract that GetMinibatchIntoNetwork() thinks it has with GetMinibatch() regarding the meaning of the return value 09 December 2015, 23:59:25 UTC
d2ac9bb Frank Seide 09 December 2015, 21:59:02 UTC one more bug fix 09 December 2015, 21:59:02 UTC
06ebc74 Frank Seide 09 December 2015, 21:52:59 UTC bug fix in AddSequence(), a comparison was off by 1 09 December 2015, 21:52:59 UTC
2be7f9b Frank Seide 09 December 2015, 20:14:58 UTC changed MBLayou::SetAsSentence() to AddSequence() which now also takes an utterance id; deleted MBLayout::GetNumSamplesWithLabel() as it did the same thing as DetermineActualNumSamples() 09 December 2015, 20:14:58 UTC
084b843 Frank Seide 09 December 2015, 19:06:31 UTC (moved GetNumSamplesWithLabel() into MBLayout) 09 December 2015, 19:06:31 UTC

92dea80 Frank Seide 08 December 2015, 16:45:54 UTC removed ValidateNetwork(), BuildAndValidateSubNetwork(), and BuiltAndValidatedSubNetwork() in lieu of new method VerifyIsCompiled() which merely verifies 08 December 2015, 16:45:54 UTC
4bc7fb9 Alexey Reznichenko 08 December 2015, 15:39:20 UTC Revert accidenatlly pushed "Address uniform random inconsistencies" This reverts commit 643139e5e9896b08583c35c586f9e1380c1c28ee. 08 December 2015, 15:39:20 UTC
643139e Alexey Reznichenko 08 December 2015, 09:28:34 UTC Address uniform random inconsistencies * Use mt19937 instead of ranlux64_base_01. Replace std random with boost random. * Fix floating point issues in _rescaleToRange. Flip range to [min, max). Add CUDA intrinsics and a unit test for doubles. 08 December 2015, 09:31:57 UTC
98b4b3d Frank Seide 08 December 2015, 02:12:50 UTC (bug fix: previous check-in had a wrong type parameter which caused it to fail for precision 'double') 08 December 2015, 02:12:50 UTC
e6583bf Frank Seide 08 December 2015, 01:54:34 UTC FormNestedNetwork() now only creates it, but one must now use the new non-lazy GetNestedNetwork() method to get it; deleted m_cacheGradientCalcOrders 08 December 2015, 01:54:34 UTC
4869583 Frank Seide 08 December 2015, 01:29:35 UTC ProcessPassNDLScript() did one too many ValidateNetwork(), which conflicted with the new CompileNetwork() approach 08 December 2015, 01:29:35 UTC
98ed2c9 Frank Seide 08 December 2015, 01:06:20 UTC made gcc happy 08 December 2015, 01:06:20 UTC
1b19264 Frank Seide 08 December 2015, 00:57:19 UTC GetEvalOrder() is no longer lazy, instead must call FormEvalOrder() before (in CompileNetwork()); deleted GetGradientCalcOrder() because its result is now always the straight reverse of GetEvalOrder(). EnumerateNodes() no longer needs to know whether to go forward or backward; bug fix: CompileNetwork() now calls CollectInputAndLearnableParameters() after FormEvalOrder() since GetEvalOrder() is no longer lazy 08 December 2015, 00:57:19 UTC
233b452 Frank Seide 07 December 2015, 23:57:47 UTC Merge branch 'master' of https://git.codeplex.com/cntk into fseide/network 07 December 2015, 23:57:47 UTC
df0d890 Frank Seide 07 December 2015, 23:57:28 UTC ComputationNetworkBuilder::NewNode() and related functions no longer return nullptr upon failure, but throw (their return value was not checked everywhere) 07 December 2015, 23:57:28 UTC
76f8114 Frank Seide 07 December 2015, 23:09:29 UTC changed how the network is prepared for computation. The goal is to move away from lazy creation of the various evaluation structures: new method ComputationNetwork::CompileNetwork() which precomputes everything, and is called after a network was created or loaded (or modified in case of old MEL); renamed UpdateEvalTimeStamp() to BumpEvalTimeStamp() and ResetEvalTimeStamp() to ResetEvalTimeStamps(); removed lots of ResetEvalTimeStamps() calls from SimpleNetworkBuilder functions, since there is now a global CompileNetwork() call at the end for all network types, which does this; renamed ClearNet() to ClearNetwork(); Load() and LoadPersistableParameters(), which were 80% identical, now share a common sub-function; renamed m_recurrentInfo to m_allSEQNodes; renamed GetOuterLoopNode() to FormNestedNetwork(); bug fix in ErrorPredictionNode: lacked an UpdateFunctionMBSize() overload. This was a reason why we had to allocate matrices early on 07 December 2015, 23:09:29 UTC
