Do you want to add the Protea/Marriot hotel as a suggestion? It's very
close to SAAO for those who can foot the bill...

Re: [casper] UltraScale+ 100G Ethernet Configuration

[Adam Isaacson]

Hi Arash,

I am afraid I don't have the expertise on this yet or a solution to this
problem. We also have a VCU118 board and will be implementing a 100GbE
yellow block in the months to come, so it would be good to stay in touch
about this - maybe not duplicate work, but help one another if time
pressures allow.

Kind regards,

[casper] Hardware/Yellow Block Porting Workshop - 30 July - 3 August, SAAO, Cape Town

[Adam Isaacson]

Hi Casperites,

Thanks to those of you that filled in the Doodle poll. We have a venue and
a date! Please see details below and diarise:

*Workshop:* Hardware/Yellow Block Porting Workshop

*Workshop Leadership Team: *Jack Hickish (University of Berkeley), Jonathon
Kocz (Caltech) (TBC), Wesley New (SARAO), Adam Isaacson (SARAO) and Amish
Patel (SARAO)

*Workshop Description: *
1) You bring your completed firmware with hardware and we will help you
integrate it into the new CASPER toolflow, so that you can target your
hardware with the new CASPER toolflow
2) We will show you how take existing firmware and create a yellow block.
3) Workshop will be run informally and will be hands on

*Workshop Prerequisites: *

I would suggest, at least, having run through tutorial 1 and tutorial 2 to
familiarise yourself with Ubuntu, Matlab and Vivado- see tutorial section
under http://casper-dsp.org (new unofficially released CASPER site)

*Venue:* South African Astronomical Observatory (SAAO), Cape Town,
Auditorium
*Date: *30 July - 3rd August 2018
*Time:* 9am - 5pm
*Workshop Cost:* Free :)

*Accommodation:* I suggest City Lodge Pinelands (
https://clhg.com/hotels/155/City-Lodge-Hotel-Pinelands-Cape-Town
)

*Directions:* https://www.saao.ac.za/contact-2/ (Cape Town) - just between
the River Club and Valkenburg hospital here in the suburb of Observatory.
Security will direct you to the auditorium after you have signed in.

*What to Bring:* Your lap top/desktop, target hardware, ethernet switches,
cables and firmware. We will cater for the food and venue hire. There is
internet availability (WiFi) at the venue.

*RSVP:* Please respond to my email (aisaac...@ska.ac.za) and not the whole
CASPER emailing group, if you will be attending by no later than the *31
March 2018*, thanks.

If you reply, it would also be great if you could give some background as
to what software tools you are currently using and what you want to achieve
through this workshop. I would like to know whether you are a beginner or
advanced.

All further communication will be sent out to participants. I hope to see
you there!

Kind regards,

Adam Isaacson
