With Intel seemingly ramping up work on their open-source OSPray portable ray-tracing engine now that they have pulled it under their oneAPI umbrella as part of a forthcoming rendering tool-kit, I figured it would be the latest interesting candidate for benchmarking of AMD EPYC 7742 vs. Intel Xeon Platinum 8280 performance. In addition, the Embree ray-tracing kernels are also being benchmarked as part of this performance comparison.

OpenMandriva is one of the few Linux distributions (and arguably the only prominent one) that uses LLVM Clang as its default compiler toolchain over GCC for building its packages and the preferred C/C++ compiler exposed to its users. One of the last hold outs for this Clang'ed Linux distribution has been the kernel build but that is now no longer a blocker...

The virtual GPU/display landscape particularly for having accelerated guest graphics was once non-existent and then suffering for the open-source Linux virtualization stack around QEMU, but that is no longer the case. There are options these days to rival the GPU/display offerings of VirtualBox and VMware albeit to newcomers may not be so clear...

It turns out Linux 5.3 shipped with potentially subpar performance for the allocation of hugepages but that should be rectified in the now open Linux 5.4 cycle for trying to provide a sane default allocation strategy on NUMA boxes...

While CPU speculative execution has caused a lot of frustrations over the past two years due to the likes of the Spectre vulnerabilities, it turns out CPU speculative execution can be exploited to be a viable source of random entropy for random number generators...

It was just two days ago that Richard Stallman said he would continue as head of the GNU project after last week having resigned as head of the Free Software Foundation (as well as his post at MIT), but this afternoon he reportedly has stepped down from his GNU leadership role...

Given recent updates to the Intel Scalable Video Technology (SVT) open-source video encoders as well as other open-source video encoders/decoders, here is a fresh look at the performance of the AMD EPYC 7742 2P server against the Intel competition with the dual Xeon Platinum 8280...

Added back during the Linux 5.1 cycle was IO_uring for fast and efficient I/O. This new interface allows for queue rings to be shared between the application and kernel to avoid excess copies and other efficiency improvements over the existing Linux AIO code. With Linux 5.4, IO_uring is in even better shape...
