* | Disable Packet2f/2i halfpacket support in NEON. | Benoit Jacob | 2015-02-27 |
| | | | | | | I believe that it was erroneously turned on, since Packet2f/2i intrinsics are unimplemented, and code trying to use halfpackets just fails to compile on NEON, as it tries to use the default implementation of pload/pstore and the types don't match. | ||
* | Replace a static assert by a runtime one, fixes the build of unit tests on ARM | Benoit Jacob | 2015-02-27 |
| | | | | | Also safely assert in the non-implemented path that should never be taken in practice, and would return wrong results. | ||

| | | | | | | | inlines. It performs extremely well on Haswell. The main issue is to reliably and quickly find the actual cache size to be used for our 2nd level of blocking, that is: max(l2,l3/nb_core_sharing_l3) | ||

* | So I extensively measured the impact of the offset in this prefetch. I tried ↵ | Benoit Jacob | 2015-02-25 |
| | | | | | | | | | | | | | | offset values from 0 to 128 (on this float* pointer, so implicitly times 4 bytes). On x86, I tested a Sandy Bridge with AVX with 12M cache and a Haswell with AVX+FMA with 6M cache on MatrixXf sizes up to 2400. I could not see any significant impact of this offset. On Nexus 5, the offset has a slight effect: values around 32 (times sizeof float) are worst. Anything else is the same: the current 64 (8*pk), or... 0. So let's just go with 0! Note that we needed a fix anyway for not accounting for the value of RhsProgress. 0 nicely avoids the issue altogether! | ||

* | Fix my recent prefetch changes: | Benoit Jacob | 2015-02-23 |
| | | | | | | | | | | | - the first prefetch is actually harmful on Haswell with FMA, but it is the most beneficial on ARM. - the second prefetch... I was very stupid and multiplied by sizeof(scalar) and offset of a scalar* pointer. The old offset was 64; pk = 8, so 64=pk*8. So this effectively restores the older offset. Actually, there were two prefetches here, one with offset 48 and one with offset 64. I could not confirm any benefit from this strange 48 offset on either the haswell or my ARM device. | ||

* | bug #955 - Implement a rotating kernel alternative in the 3px4 gebp path | Benoit Jacob | 2015-02-18 |
| | | | | | | | | This is substantially faster on ARM, where it's important to minimize the number of loads. This is specific to the case where all packet types are of size 4. I made my best attempt to minimize how dirty this is... opinions welcome. Eventually one could have a generic rotated kernel, but it would take some work to get there. Also, on sandy bridge, in my experience, it's not beneficial (even about 1% slower). | ||
