...endencies cannot issue immediately. The benchmark was intentionally written to avoid this hazard but LLVM's code generator seems to ignore that when it schedules instructions. When I run this benchmark on my 2.83 GHz CPU, I observe the following performance results: 1 threads 0.648891 GFLOP/s 2 threads 1.489049 GFLOP/s 3 threads 2.209838 GFLOP/s 4 threads 2.940443 GFLOP/s When I rewrite the generated assembly by hand to exhibit the same interleaving as in the LLVM IR form . . mulss %xmm8, %xmm10 mulss %xmm7, %xmm9 mulss %xmm6,...

Hi Tobias, according to [1], we can expect 90% of the turbo boost peak of the processor with a C version of Matrix-Matrix Multiplication that is similar to the one presented in [1]. In case of Intel Core i7-3820 SandyBridge, the theoretical maximal performance of the machine is 28.8 gflops and hence the expected number is 25,92 gflops. However, in case of, for example, n = m = 1056 and k = 1024 a code based on BLIS framework takes 0.088919 seconds and hence 25,68 gflops. I’m not sure whether a C implementation, which similar to one the presented in [1], can outperform a code based...

Hi, has anyone tried to compile the lustre patchless client on a debian linux for arm architecture? Could be possible to do? Thanks in advance.

...block. In addition to this kind of parallelism, grids of blocks (which do not share memory, unlike threads within the same block) can be used to process several audio frames at once. This is somewhat tricky, given the explicitly stream-oriented API, and also some CUDA peculiarities. With the 330 GFLOPS from the current cards... I'd expect quite a significant acceleration. Does anyone find this interesting? Josh: do you think this would be worth including in the FLAC codebase when implemented? -- boris

...tinuum is a smartphone the other end of, exactly? The one in my pocket has multiple general-purpose GHz-class CPU cores, a few specialized coprocessors, several hundred megs of RAM, dozens of gigs of fast local storage, and several high-tech radios. Its raw processing power is on the order of 100 GFLOPS.

I have a coworker, who''s primary expertise is in another flavor of Unix. This coworker lists floating point operations as one of ZFS detriments. I''s not really sure what he means specifically, or where he got this reference from. In an effort to refute what I believe is an error or misunderstanding on his part, I have spent time on Yahoo, Google, the ZFS section of

To improve the performance of scripts that manipulate zfs snapshots and the zfs snapshot service in perticular there needs to be a way to list all the snapshots for a given object and only the snapshots for that object. There are two RFEs filed that cover this: http://bugs.opensolaris.org/view_bug.do?bug_id=6352014 : ''zfs list'' should have an option to only present direct
