FPTalks Community Meeting (Mar 5): Ichitaro Yamazaki (Sandia) on large-scale linear systems

[Zachary Tatlock]

Howdy folks!

Next Thursday, March 5 at 9:00-10:00 AM pacific time, we’ll have the next FPTalks Community Meeting on this Zoom:

We’re super excited to welcome Ichitaro Yamazaki from Sandia National Laboratories to present on Challenges and opportunities in large-scale linear systems. Here's the abstract:

Linear solvers often play paramount roles in large-sale scientific and engineering simulations. In order to maintain the quality of our software's functionalities and performance over various hardwares, our solvers are implemented within the open-source software framework, called Trilinos. However, it is still a challenge to maintain the robust implementation of the parallel solvers, and we often spend significant amount of time maintaining our solvers on each new hardware. Furthermore, in order to effectively utilize the current large-scale computers, many techniques have been proposed (communication avoiding/hiding, asynchronous communication, mixed-precision, random sketching, etc.), which often pose further challenges to maintain the reliability of our solvers. In this talk, we discuss some of these techniques integrated into our solvers, and associated challenges. The hope is to see if there are any potential collaboration in order to enhance the reliabilities of our solver implementations on the current and emerging computers.

Looking forward to seeing everyone!

As a reminder, if you would like to give a talk or know of someone that would be great for an FPBench Community meeting, please have them fill out the speaker suggestion form!
