[Beowulf] FPGA storage accelerator

[John Hearns via Beowulf]

It’s so interesting to look at what was old being new again though.

Lovely insight as always Joe!

Indeed. Ideas always come around again in computing.

My aphorism - always follow the herd. Look at what everyone is buying an
implementing.
Don't delve too deeply into the technical minutae of a particular
technology which takes your interest.
For if you don't follow the herd it will trample you.

lying flattened on the plains)

Ha! "Then maybe, just maybe, perhaps 640 PB ought to be enough. Maybe."

Thanks for spotting that. I really am trying. Peebees :-)

Back in 2005 or so, we had these little USB connected FPGA
Yep!

ATM Networking?

ATM isn't dead, it's just morphed a little...

cheers,
Chris (built an on-site ATM network back in the mid 90s)

ATM
 I remember it well- it was going to be: “100 Mbps + to the desktop!” so you don’t have rely on an ISDN PRI or a 10Mbps ethernet.
The next step past ISDN (“It still doesn’t network”) although I had a BRI to my apartment, then house, for several years. We had ISDN phones at JPL for a number of years, and now we’re all Cisco VOIP phones – heck, the astronauts on ISS call home on a unmodified Cisco VOIP phone. I guess Cisco was more motivated to deliver a “solve everyone’s problems” solution than the fractious baby bells.

I remember well ATM’s short packets (so you don’t need echo suppressors within continental France) – compared to 100Mbps Ethernet Jumbo frames that became pervasive, and now we’re GigE to the desktop.

Silicon is wonderful – you can make adaptive equalizers that figure out and compensate for all the impedance discontinuities getting from chip to board to connector to cable etc. If you had asked me, in 1985 as an RF /DSP kind of guy, will we send many Gbps over twisted pair for a few dollars/port I would have said that would be quite a feat.

ATM… I remember it well- it was going to be: “100 Mbps + to the desktop!”

Ah yes, I had an OC3 link to my DEC Alpha from the network we built, 155Mbps
to my desktop in the mid 1990s! :-)

I remember well ATM’s short packets (so you don’t need echo suppressors
within continental France)

Yeah, France wanted 32 byte payloads for that, the rest of the world wanted 64
bytes so they compromised and we got 48 bytes (plus header giving 53 byte
cells). Not sure how that worked out for France in the end! :-/
