X10 Day Tokyo 2015

The X10 Users Community proudly presents the second X10 Day Tokyo.

Date and Time: Thursday 29 January 2015, 9:30-18:00
Place: IBM Research - Tokyo (Toyosu)

Agenda:

9:30 - X10 tutorial (in Japanese)
13:00 - Keynote by Dr. Vijay Saraswat
14:30 - Presentations by selected X10 related projects in Japan (program to be announced shortly)
18:30 - (Optional) paid social dinner

We invite most of the serious X10 users in Japan as well as the active X10 project members from IBM Research - Tokyo, so it should be a good opportunity to meet them in person and discuss the current and the future X10 language and its applications.

We also welcome prospective X10 users who would like to master the language quickly. X10 tutorial in the morning is a perfect fit for you. Don't hesitate to join us.

IIT Madras Benchmark Suite Released

A new kernel benchmark suite -- IMSuite: IIT Madras benchmark suite for simulating distributed algorithms has been released. IMSuite implements twelve classical distributed algorithms in two task parallel languages - X10 (x10-2.3.0) and HJ.  IMSuite is an open source benchmark suite, which can be freely downloaded at: http://www.cse.iitm.ac.in/~suyash/imsuite/

The slides and sample programs from the first X10 2.4 tutorial APGAS Programming in X10 given at the Hartree Centre Summer School are now available. 

X10 won the HPC Challenge "Best Performance" Award in the Class II competition at SC'12.

The X10 submission (paper, presentation, code) was based on X10 code for Global HPL, Global Random Access and Global FFT and Unbalanced Tree Search (UTS) benchmarks and performance runs on the PERCS machine. All benchmarks were run at 32K cores, some also at 55K cores. We showed good scaling and good to outstanding absolute performance on all benchmarks. More details are available at the HPC Challenge 2012 Awards page.

All papers and presentations from the X10 2012 Workshop are now available from the workshop program page.  Videos of the X10 tutorial and the Main Memory Map Reduce presentations are also available.
