This commit adds a formal specification of tvdiff_usec and a partial specification of subtract_timeval. These may be proved using Frama-C. The existing functions ignored overflow, but it is possible to call the functions with parameters that will cause overflow. So to create a formal specification I had to modify the functions to signal overflow. Luckily GCC and Clang have convenient

This series is based on my blog posting here: https://rwmj.wordpress.com/2019/09/13/nbdkit-supports-exportnames/ It depends on the fix for realloc: https://www.redhat.com/archives/libguestfs/2019-September/thread.html#00103 This series adds a fun plugin, and also an semi-related feature I've long thought to be desirable. You can consider patches 1 & 4, and patches 2 & 3 as forming

I imagine that most interesting load/store optimizations happen before vectorization, so I am not sure how much we can gain by optimizing masked load/stores.

I want to compare two documents in the index (i.e. retrieve the cosine similarity/score between two documents term-vector''s). Is this possible using the standard Ferret functionality? Thanks in advance, Jeroen Bulters -- Posted via http://www.ruby-forum.com/.

- Use more friendly output with GiB and MiB/s - Measure time per operation, providing finer grain stats - Add total stats for understanding system throughput - Add missing stats for flush I hope that these changes will help to understand and improve virt-v2v performance. Changes since v1: - Keep bytes values - Increase precision to 0.001 GiB and 0.001 MiB/s - Add total stats - Show time before

We're looking at how to handle masked vector operations in architectures like Knight's Corner. In our case, we have to translate from a fully vectorized IR that has mask support to llvm IR which does not have mask support. For non-trapping instructions this is fairly straightforward: ; Input t1 = add t2, t3, mask ; llvm IR -- assuming we want zeros in the false positions, which is not

For virt-v2v we have been discussing how to limit network bandwidth. The initial discussion has been around how to use cgroups to do this limiting, and that is still probably what we will go with in the end. However this patch gives us another possibility for certain virt-v2v inputs, especially VDDK. We could apply a filter on top of the nbdkit plugin which limits the rate at which it copies
