You have 16 NVIDIA H200 GPUs spread across 2 nodes. That is, conservatively, several 100,000 dollars of silicon sitting in a data center, connected by RDMA/InfiniBand, running Kubernetes, and serving a large language model. You're living the agentic dream (not really, but it's a great start). Except your time to 1st token (TTFT) is thousands of milliseconds.

This was done to improve the long-term security of our communications with our customers and also to meet current key recommendations from NIST (NIST SP 800-57 Pt. 1 Rev. 4 and NIST SP 800-131A Rev. 1). The old key will continue to be valid for some time, but it is preferred that all future correspondence use the new key.

As part of our commitment to the wider user community, we are introducing this tool via this article. This tool is not a Red Hat product. As such, it is not supported and does not come with any kind of warranty. The tool only works on static binaries and does not simulate an entire running system. This means it will neither follow jumps through 2018-07-18T13:30:00+00:00Red Hat Security Blog (legacy)tag:trvny.github.io,2024:feedseek/redhat/feda5e7c9a1c552dRed Hat’s disclosure process2018-07-10T13:00:00+00:00Last week, a vulnerability ( CVE-2018-10892 ) that affected CRI-O, Buildah, Podman, and Docker was made public before some affected upstream projects were notified. We regret that this was not handled in a way that lives up to our own standards around responsible disclosure. It has caused us to look back to see what went wrong so as to prevent this from happening in the future.

Unfortunately, many times the answer is that "tool X does not measure Y." This leads to a dicussion about the performance problem being investigated. With additional background information, it becomes much easier to suggest more promising tools and techniques to get the desired measurements.

The cache has access latencies ranging from a few processor cycles to 10 or 20 cycles, rather than the hundreds of cycles needed to access RAM. If the processor must frequently obtain data from the RAM rather than the cache, performance will suffer. With Red Hat Enterprise Linux 6 and later distributions, the system use of cache can be measured with the perf utility avail2014-03-26T20:39:35+00:00Red Hat Performance Blog (legacy)tag:trvny.github.io,2024:feedseek/redhat/4f71f2d6dc541760Examining Huge Pages or Transparent Huge Pages Performance2014-03-26T20:35:16+00:00All modern processors use page-based mechanisms to translate the user-space processes virtual addresses into physical addresses for RAM. The pages are commonly 4KB in size, and the processor can hold a limited number of virtual-to-physical address mappings in the Translation Lookaside Buffers (TLB). The number of TLB entries ranges from tens to hundreds of mappings. This limits a processor to a few megabytes of memory it can address without changing the TLB entries.
