Right after the conference in Tucson, I had to go the the SC11/SC12 committee meeting in Seattle. It didn’t seem useful to fly back to Champaign over the weekend (I could have spent 20 hours in planes and 6 hours at home, probably sleeping anyway. So I just stayed in Seattle over the weekend. I received very bad news during that trip but fortunately, I was around a friend and we went hiking in Seattle (thanks Frank!).

We did two day-hikes that were not trivial. Unfortunately, I had my knee injured before but it was ok. On the first day, we climbed mount SI, acutally, we climbed from the bottom to the *very* top (the rock thing on the top!!). This was quite a hike. Approximately 4000 feet height difference and three hours walking (one way). The last climb was up a massive rock wall, it was very dangerous (adrenaline!) but also very impressive and nice. We beat the mountain!

The second day hike was to a large waterfall and a lake at the top of a mountain at Lake Serene. It was just stunningly beautiful even though I got a bit wet in the waterfall, and slipping was somewhat dangerous too :-).

Here is the GPS tracking of our Lake Serene hike (my new phone rocks!):

Here are some pictures:

This year’s ICS has been in Tucson, AZ. I have served on the program committee and also contributed two papers (one with Marc Snir and the other one with the folks from IU) to the conference. I also co-chaired a workshop with Kamil Iskra. So I had tons of reasons to go there — I wasn’t very thrilled about the location (isn’t Arizona a boring desert, eh?). And actually, it’s not too easy to get to Tucson, it was a 21 hour travel from Zurich *uff*.

Well, I was very surprised! The hotel was just amazing and the landscape even more. I would have never believed that such large cacti exist! I mean – wow! And they’re hundreds of years old. The pool was also amazing, during the day it was full of “tourists” and at night, many computer scientists accumulated around (and in) it :-). It was really nice!

The conference was amazingly well organized. Actually, this was one of the best (if not *the* best) conference I visited since a long time! Congratulations Dave!

Here are some pictures:

I’ve been at IPDPS in Alaska this week. Actually, not just in Alaska but in *the* city in Alaska, Anchorage! Well, I was shocked, seriously. Achorage supposedly had 300.000 citizens, however, it seemed much smaller than Champaign or Chemnitz! There was really nothing happening there :-(. The mountains in the background are extremely nice, I agree.

The other nice things was that it was effectively light until 12am. It’s really weird when you step out of a bar at 11pm and it’s like noon …. well, one weird thing was that all the natives seem to be drunk after 10pm for some reason. As I said, a strange place!

The conference was amazing! It seemed to me as if I knew every other person. And the IPDPS 25th anniversary show and Moose and Awards sessions were just great (with the right people around ;-)).

This year, I was chairing the HIPS workshop there which also went extremely well! We had 58 attendees during the (excellent) keynote of John Mellor-Crummey!

Unfortunately, I had barely time to visit the wildlife, but we made a small trip. Here are some pictures to get an impression of Alaska (it’s basically like the Alps, nothing too special).

Interestingly, it wasn’t all that cold, around 12-15 degree Celsius. A fun fact is that Monday was colder in Champaign (10 degree Celsius) than in Alaska (14 degree Celsius) :-).

Yes, I have been there! Eklutna lake, near Anchorage!

Mountains …

More mountains …

View on the city (small, isn’t it?)

Even more mountains …

(Thanks to Jens and Thomas for the pictures, I forgot my camera …!)

This week I have been at the DOE ASCR Exascale meeting in San Diego. It was actually a very nice and informative meeting. I hope the strategy documents will be published soon. We identified a couple of challenges for Exascale (yes, more challenges :-)).

My flight was in the afternoon of the last day and nobody else was around that afternoon :-(. Well, so I decided to take the local commuter train to Mexico ($2.50 each way ;-)). It’s pretty cool, one usually doesn’t walk across international borders like this. The funny thing was that nobody cared when I walked into Mexico (the officer was sleeping), however, the controls to get back in the US were extremely strict so that there was a line of at least 1000 people and I would have missed my plane if I wouldn’t have walked to the front of the line (which worked surprisingly well).

Here are some pictures:

Apparently, the parking Lot and Mexico are the same direction 🙂

Glad that I didn’t come by car, seems like there are more serious controls.

The famous US-Mexican border, well, not too spectacular.

Walking through those prison-bar things is actually fun, and they twist rather fast if you want ;-).

The border stone, not sure why it says something about water commission there??

The only Mexican guard (the immigration officer was sleeping on his chair a bit further but they didn’t want me to take pictures. Too bad. Btw., this guy had a G3 *lol*.

Very very inviting … really. I read that many people are robbed in this area.

But they had a gigantic flag! Viva la Mexico!

Well, time to go home (there was really not much to see actually — but the food was just *awesome*. I love *real* Mexican food now! Cilantro is not that bad if it’s used in the right combination.). Those signs were actually very helpful for dumb tourists like me.

Taco Bell has a branch in Mexico. If they know?

Probably Tijuana’s main sight, well, kinda sad but it’s humongous and the steel rods make funny noises in the wind.

Again, good that I didn’t go by car, the line into the US was hideous and sneaking to the front seems harder by car ;-).

All-in-all an experience that I didn’t want to miss. I didn’t have much time though, but I guess Tijuana is not that touristy in general ;-).
