A bug in vsldConvExec

Zbigniew_L_ — Thu, 02 Apr 2015 17:53:47 GMT

I use 64-bit AMD Linux machine. When I run the test file (attached) I get wrong results with the current MKL 11.2 update 2:

EXAMPLE executing a convolution task
result: z[0]=1343342.8
result: z[1]=1333310.3
result: z[2]=1323248.1
result: z[3]=1313220.0
result: z[4]=1303165.3
result: z[5]=1293145.8
result: z[6]=1283102.6
result: z[7]=1273095.5
result: z[8]=1263067.9
result: z[9]=1253077.2
result: z[10]=1243069.1
...

But when I switch to MKL 11.1 update 2 I get the correct results:

result: z[0]=1.0
result: z[1]=4.0
result: z[2]=10.0
result: z[3]=20.0
result: z[4]=35.0
result: z[5]=56.0
result: z[6]=84.0
result: z[7]=120.0
result: z[8]=165.0
result: z[9]=220.0
result: z[10]=286.0
...
