Finally reached my true rank and this is only the beginning ♥️ This is what my ( the best mercy EU ) stats look like if you wanna know. I feel like i have truly unlocked Mercys' full potential with her recent changes ♥️😇#heroesneverdie #mercy #GMsupport

I wanna thank my mercy influencers for helping me improve on this hard journey. Improvement takes time, 34 seasons and counting i will never stop trying. @skiesti_ @Animetic @LuxyCoulee @KhaleesiBB @AngelxoTv @HoshizoraOW @eleyzhau @Niandra_ @AquaBoostTV
I have benchmarked the new @AMDInstinct MI250 #GPU at @fzj_jsc, and it is disappointing but also impressive. Let me explain.

The #MI250 is misleadingly marketed as "one chiplet GPU" with 13312C, 90TFLOPs & 128GB @ 3.2TB/s.
But it is not. The 2 GCDs are 2 separate GPUs with 64GB each, like a K80 dual-GPU but in a socket. One #GPU can't directly access the other's memory.

To use both GCDs, the software needs to be multi-GPU capable. For many algorithms this is very difficult and for some it is entirely infeasible. The desire for large unified memory is huge.
The #MI250 promises exactly that with "128GB", but delivers only half.

1/11 Ever wondered how Supercomputers multiply? Efficient multiplication is a critical part of traditional high performance computing as well as machine learning. Let's look at the #IBM Blue Gene/Q, which led the #Top500 and #Green500 in the late 2000s.

2/11 IBM Open Sourced the core to Blue Gene/Q (the @OpenPOWERorg A2I) so it offers a fantastic insight into a CPU that taped out at frequency and in volume. The #VHDL for the core is available at:

3/11 We quickly see that it uses a few well established techniques for optimising multiplication. The first step uses Booth encoding:

People have asked me about my #Top1000 list and how it is calculated so I thought I would do a thread about it.
I have been doing this list for over 10 years since I joined Twitter in April 2009 as I wanted a way to grow my followers and also reward engagement.

It started as a #Top500 list but a few years ago I changed it to a #Top1000 list.
I don't determine where people are in the list as it is based on people engaging with with my tweets over a 7 day period since my last list update.

I award Engagement Points for different activities as follows:
Retweets 9 points.
Replies 6 points.
Likes 3 points.
I accumulate the totals for each person in a file and I have an Excel Spreadsheet and VB Macros to produce the list. It also builds the blog post and tweets.

2/ Nvidia announced A100 this morning and you can read about it from any number of outlets, e.g. nextplatform.com/2020/05/14/nvi…
3/ Nvidia, as usual, have themselves published a great set of detailed blogs about the architecture and specs, really diving into the approaches they've taken and how they might impact workloads.
