In Tomasulo’s algorithm, how do reservation stations recognise which results are directed to them, especially where functional units are pipelined?

I am currently researching instruction level parallelism in CPUs and have come across Tomasulo’s algorithm for dynamic scheduling.

As I understand it so far, once a functional unit computes a result, it is sent on the CDB from which it can be received by reservation stations waiting for this result. How do these reservation stations recognise that the result is one they are waiting for? I assume results sent on the CDB are tagged with the ID of the reservation station involved in computing them, but then how is this implemented where the functional units are pipelined or there are multiple reservation stations per functional unit? Is the ID of the reservation station corresponding to the instruction being executed passed through the functional unit’s pipeline to be used as a tag when the result is sent?

Shortest path between any origin to any destination through some way stations

How can one find the shortest path between any one of the origins to any one of the destinations through a number of way stations on the way using Dijkstra algorithm?

You can visit those way stations in any order. There will be multiple origins and multiple destinations, but a path from any origin to any destination will suffice as long as it’s the shortest.

theoretical question about difference between transmitting stations in Bit-Map Protocol

i am wondering about the difference between the transmitting station in a bit map protocol.

for instance, if we have 8 broadcasting stations numbered 0-7, and the racing (contenting) time is $ t_0$ and the length of each broadcasting frame is $ 20t_0$

then, will there be a difference, if for instance, only station 0 wants to broadcast in each time slot and all of the other stations doesn’t want to broadcast at all(at any time slot), or the exact same thing if the only station that wants to broadcast in each time slot is station 2?

is there any difference except of the station number(both seem to be low numbers)?

curious about that

Are gas/petrol stations in Ireland typically “pump your own gas/petrol”?

In past trips to Ireland, I remember petrol stations being full-service like the US states of Oregon and New Jersey. I also remember a few self-service stations. But I don’t recall which was more prevalent and I am sure its changed since I last visited.

But what kind of service is typically found nowadays in Ireland?

And if it is self-service, are they typically pay at the pump with credit card?

Which Caltrain stations only have parking for Caltrain train customers only?

Which Caltrain stations only have parking for Caltrain train customers only?


http://www.caltrain.com/riderinfo/Parking.html indicates which Caltrain stations have parking (e.g. http://www.caltrain.com/stations/mountainviewstation.html -> “340 [parking] spaces; pay through ticket vending machine”), but I couldn’t find any information regarding which Caltrain stations have parking for Caltrain train customers only. Looking at the Caltrain parking signs online, I see some mention “Permit Parking for Caltrain Patrons ONLY” or some don’t.

E.g., from https://www.parkme.com/en-gb/lot/187135/mountain-view-station-mountain-view-ca, found by Nate Eldredge: “Permit Parking for Caltrain Patrons ONLY”.

enter image description here

and some doesn’t mention it, e.g. from https://www.parkme.com/en-gb/lot/187136/palo-alto-caltrain-station-palo-alto-ca:

enter image description here

Note that parkme.com doesn’t have a picture of the parking sign for each Caltrain station (e.g. https://www.parkme.com/en-gb/lot/225138/sunnyvale-station-sunnyvale-ca).

OpenBTS mobile stations loose network connection

Initial setup

OpenBTS installed on Ubuntu 16.04, two mobile phones connected to the OpenBTS network. Transceiver is USRP X310.

Problem

In turn, the phones loose connection to the network for some seconds.

If i initiate a call from a phone while it is in “no-network moment”, the OpenBTS server does not receive anything. Dial error is displayed on the phone.

If a phone that is in “no-network moment” is called by a working phone, the call fails. Asterisk log return:

Any idea about what could be the cause? Thank you

How can I find which police stations in Taiwan have camping facilities for cyclists?

Two and a half years ago I walked and hitchhiked around the island of Taiwan. I liked it so much I’m starting my next trip by doing it again.

Ar into my trip I learned that some police stations, especially in rural areas, especially on the east coast, actually provide camping facilities for cyclists. (And walkers can use them too.)

This time I’d like to make the best use of them. So I’m looking for their official site, an official list of them, or any unofficial list.

I’m especially interested in whether they exist elsewhere on the island. I passed by or visited a couple of random police stations for unrelated reasons on my last trip and the one in Dulan, Taitung was the only one I saw with my own eyes.
