Invalid SSL certificate








What happened?

The origin web server does not have a valid SSL certificate.

What can I do?

If you're a visitor of this website:

Please try again in a few minutes.

If you're the owner of this website:

The SSL certificate presented by the server did not pass validation. This could indicate an expired SSL certificate or a certificate that does not include the requested domain name. Please contact your hosting provider to ensure that an up-to-date and valid SSL certificate issued by a Certificate Authority is configured for this domain name on the origin server.

It appears there has been some misinformation spreading. The memory barrier requirement was referring to popular lock-based synchronization mechanisms and has nothing to do with the work stealing memory barrier example (where language used is "may" specifically because of the bounded nature of store buffers and invalidation queues).

All I can say is, A complex topic very well explained. http://goo.gl/XhFtP

Wondering about value of the x86 Fetch and Add Op rather than CAS to reduce contention costs.

"Consider, for example, the fetch-and-add (F&A) primitive. Figure 1 shows the difference in the time it takes a thread to increment a contended counter on a modern x86 system when using F&A vs. a CAS loop. Avoiding the retries and paying only the synchronization price leads to a 46 performance improvement. In this 2013 paper we transfer this insight to the domain of FIFO queues, henceforth simply queues"
