[JLSE-Intel-NDA] B0 Stream triad
by Vitali A. Morozov 25 Mar '16

25 Mar '16

Hello, here are the figures that I have obtained for STREAM triad. The peak numbers are: L2 peak bandwidth 44.7 GB/s, based on the size of the request table, L2 hit latency, and core capabilities to issue memory requests clocked at 1.3 GHz. MCDRAM peak bandwidth 480 GB/s scaled down to 1 port of L2 tile => 15 GB/s. Could be slightly less if the port was provisioned to 36 tiles (13.3 GB/s in this case). DDR4 peak bandwidth 112 GB/s is based on 6 channel DDR4-2400. Being scaled down to 2134 GT/s, it will be 100 GB/s. The first graph provides STREAM triad bandwidth for 1 core and 1 tile (2 cores, 1 thread is running on each core). I do not look at L2 cache bandwidth, as 44.7 GB/s number is very hard to reach and there might be many factors that can reduce effective bandwidth (moreover, I was not carefully coding stream to get the full L2 bandwidth anyway). The measured 32 GB/s from a core and 37 GB/s for 2 cores on a tile are within 80% of expected tolerance. Running more then 2 threads on a tile severely degrades performance (20 GB/s at best), which is expected as the L2 request table gets quickly full. When data fits into MCDRAM, I have measured 10-12 GB/s for a core and 10-13 GB/s for a tile with strange repeatable artifacts at around 64 MB and 640 MB. The tile performance is more uniform, but starts quickly degrade at around 900 MB, which is strange as we should have plenty of room in MCDRAM. Also, I am measuring triad, so the cache must be warmed out by the time I started it as triad is one of the last benchmarks in STREAM suite. In fact I do not expect any performance drop between about 8 MB up to 192 GB - the memory bandwidth should be capable to provide single port MCDRAM-available bandwidth at ease. The second graph provides STREAM triad numbers for 8 tiles. Again L2 cache bandwidth is a kind of OK except that it quickly gets down not reaching the expected max of 8 MB combined L2 cache. The MCDRAM bandwidth is within the expected range (with a very strange dip in between 12 - 40 MB. Then, the bandwidth decreases with a very unusual change of curvature at around 2 GB. Even if MCDRAM does not work as cache, I would expect to see around 90 GB/s - I am measuring 4 GB/s at 38 GB. Sounds like Ben have installed CR instead of DDR :) The second graph numbers can slightly be improved with careful mapping the processes to the cores, but not very much. Vitali

The 7 coming in April are all bin-3 with 16GB and 64 cores. I asked again about the A0. They are checking. My bet is that the one person responsible for the A0 shipments is out this week and didn't tell anyone. I am not happy.

What I see must be an artifact of the way MCDRAM interacts with DDR. I am preparing a graph which demonstrates that the MCDRAM bandwidth severely drops after about 2 GB.
