08 Nov 2015 Salesforce Developers User Group Meeting [47148]
Monday, November 9th, 2015: 4:00 PM to 7:00 PM

ArtServe - Ft. Lauderdale

The Dreamforce catchup is done! By now you all should be ready to consume new information :) I hope all of you had a chance to attend Dreamforce, because it was pretty great, so great that I have been struggling to come up with original content for this next meeting. Thankfully, we have GREAT content. One of the most interesting (and mysterious) features in the platform right now are Custom Metadata Types. Someone posted on our chatter group that they would like to get more information about this, sooooo, guess what? we are gonna be talking about CMT and the feature roadmap!

22 Apr 2014 Parallel Java with Fork/Join on SPARC CMT [35939]
By Amit Hurvitz

"Java 7 Fork and Join allows an easy way to perform dividable work by executing parallel tasks on a single computing machine. This article introduced a fork/join example of counting occurrences of a word in all files/directories under a root directory. I thought to check how these forked threads scale on a T5-4 server. Oracle T5-4 server has 4 processors, each has 16 cores. CMT technology allows 8 threads contexts per core (each core includes two out-of-order integer pipelines, one floating-point unit, level 1 and 2 caches, full specs here).

It took 1131.29 seconds for a single thread to process a root directory with 1024 files, 1.25MB each. Doing the same work with Java fork/join (available from Java 7), increasing "parallelism level" - using the Java fork/join pool terminology - up to 2048, took 7.74 seconds!..."

13 Feb 2013 Rick Hetherington on the SPARC T5 [29778]
Plus 'SPARC T5: 16-core CMT Processor with Glueless 1-Hop Scaling to 8-Sockets': Hot Chips Presentation

Rick Hetherington delivers an overview of the SPARC T5 processor, explaining how doubling the number of S3 cores allows the T5 to achieve 2X throughput improvements, and how 28 nanometer silicon enables clock speed increases to 3.66 Gigaherz (GHz). Hetherington adds that on-die PCI Express Rev 3 results in a doubling of I/O bandwidth. Scaling the SPARC T5 to eight sockets and 16 cores gives the processor the capability of gluelessly interconnecting eight sockets for a total of 128 cores, each supporting up to eight independent threads totaling 1024 CPUs. An accompanying Hot Chips presentation provides a detailed look at the SPARC T5.

17 Jan 2013 Slide Sets for Two DOAG Talks: LDoms and T4 Red Crypto Stack [29388]
Considering IO Ooptions for both Disk and Networking; Securing the Database

The DOAG Konferenz & Ausstellung 2012 featured two presentations by Stefan Hinker, for which he now shares the slides in an oracle.com post. The first was entitled "LDoms IO Best Practices,"] in which he discussed different IO options for both disk and networking and gave recommendations on how to choose the right ones for your environment. The second, co-presented with Heinz-Wilhelm Fabry, was entitled "T4 and the Red Crypto Stack." The presenters showed how to use encryption and other security mechanisms throughout the red stack to deploy a quite well secured database.
