* OS: Windows 7
* CPU: i7 4770k Haswell
* MKL: 11.0 Update 1
There is a unknown program crash while calling DGEMM function with a parameter for transpose.
So DGEMM ( "N",...) is OK but DGEMM ( "T",...) fails.
AVX2 instruction set running on Haswell CPU is bug suspicious because AVX or SSE2 instruction set runs well.
mkl_cbwr_set(MKL_CBWR_AVX); // code path change
Is there any suitable way to solve this problem?
this is an unknown issue for the team and we would like to recomend you the following steps:
1. Would you please check this problem with the latest update 5? ( version 11.0.5) like Sergey Kostrov have already recommended.
2. in the case if you will continue to see the crash - then could you please give us the example of the code. we will check and investigate the problem on our side and will prepare the fix of the problem as soon as we can.
my previous message was not completely correct - we have met the similar problem which came from our internal testing but not from external customers. This is very similar issue like you reported. The fix of this issue has been available since 11.0 update 2 only. We are very sorry for inconvenience.
