Filling up Delayed Branch slots


Filling up Delayed Branch slots

seems to work fine For (A), J X is an unconditional jump to a single fixed label (presumably within the range provided by the ISA), so it does not have any data dependencies on previous instructions.
Since the ADD has a name dependence on the result of the OR, if it is to be moved after the OR the destination of the OR would have to be changed (assuming there is a free register available and that a later move can either be free in terms of scheduling or eliminated by changing the instructions that later use this value in R3 to use the register used as the destination for the OR). This would be a relatively complex change and is probably excluded from consideration.

Making missing time slots and filling in 0 values in a Pandas series

Making missing time slots and filling in 0 values in a Pandas series

it helps some times Usually when you have a Series, ts, with DatetimeIndex, you can expand it to include new dates by using ts.reindex, or ts.asfreq or ts.resample. Since ts.reindex has a fill_value parameter for filling in missing values, I think it will be easiest to use ts.reindex in this case.
However, in this problem, ts has a MultiIndex with from_station_name and starttime levels.
code :
ts = ts.unstack(level=0)
index = pd.date_range('2014-07-01', '2014-07-03', freq='H')
ts = ts.reindex(index, fill_value=0)
ts = ts.stack()
ts = ts.swaplevel(0,1)
import pandas as pd
ts = pd.Series({('900 W Harrison', '2014-07-01 08:00:00'): 1,
 ('900 W Harrison', '2014-07-01 10:00:00'): 1,
 ('900 W Harrison', '2014-07-01 11:00:00'): 1,
 ('900 W Harrison', '2014-07-01 12:00:00'): 1,
 ('900 W Harrison', '2014-07-01 13:00:00'): 1,
 ('900 W Harrison', '2014-07-01 16:00:00'): 1,
 ('900 W Harrison', '2014-07-01 17:00:00'): 3,
 ('900 W Harrison', '2014-07-01 22:00:00'): 1,
 ('900 W Harrison', '2014-07-02 01:00:00'): 1,
 ('900 W Harrison', '2014-07-02 08:00:00'): 1,
 ('900 W Harrison', '2014-07-02 12:00:00'): 2})

ts = ts.unstack(level=0)
# ensure ts.index is a DatetimeIndex
ts.index = pd.to_datetime(ts.index)
index = pd.date_range('2014-07-01', '2014-07-03', freq='H')
ts = ts.reindex(index, fill_value=0)
ts = ts.stack()
ts = ts.swaplevel(0,1)
ts = ts.sortlevel()
print(ts)

seems to work fine I would recommend doing all of the processing first and then only using foreach() to display it.
The first step is checking what kind of modification is needed to prepare your $show_listingsRecords array.
code :
$show_listingsRecords=array(
    array("name"=>1,"description"=>2,"link"=>3),
    array("name"=>4,"description"=>5,"link"=>6),
    array("name"=>7,"description"=>8,"link"=>9),
    array("name"=>10,"description"=>11,"link"=>12),
    array("name"=>13,"description"=>14,"link"=>15)
);

$alternates=array(
    array("name"=>"backup1A","description"=>"backup1B","link"=>"backup1C"),
    array("name"=>"backup2A","description"=>"backup2B","link"=>"backup2C"),
    array("name"=>"backup3A","description"=>"backup3B","link"=>"backup3C")  // needed if no listings at all
);

$chunk_size=3;  // 3 is used in this case

// conditionally prepare array
if(!$size=sizeof($show_listingsRecords)){  // if no listings at all (empty array)
    $show_listingsRecords=$alternates;
}elseif($over=$size%$chunk_size){  // $over is how many extra elements beyond "even" (0,1,2 in this case)
    $show_listingsRecords=array_merge($show_listingsRecords,array_slice($alternates,0,$chunk_size-$over));
}

// display
foreach(array_chunk($show_listingsRecords,$chunk_size) as $batch){  // iterate in batches
    echo "<div>\n";
        foreach($batch as $listing){  // iterate the arrays in the batch
            echo "\t<div>",implode(' + ',$listing),"</div>\n";
        }
    echo "</div>\n";
}
<div>
    <div>1 + 2 + 3</div>
    <div>4 + 5 + 6</div>
    <div>7 + 8 + 9</div>
</div>
<div>
    <div>10 + 11 + 12</div>
    <div>13 + 14 + 15</div>
    <div>backup1A + backup1B + backup1C</div>
</div>

wish helps you In the described pipeline the direction and target of a conditional branch is not available until the end of the third cycle, so the correct next instruction after the branch cannot be fetched (with certainty) until the beginning of the fourth cycle.

Celery workers not filling concurrency slots

Celery workers not filling concurrency slots

To fix the issue you can do Usually this is because of subprocesses filling up the concurrency slots. Celery uses by default prefork as the execution pool, and everytime you spawn a subprocess of a task (another fork), it counts as a running process to fill up the concurrency slots.
The simplest way to avoid this is by using eventlet, which will allow you to spawn multiple async calls on each task. However, this requires that none of your tasks have blocking calls, such as subprocess.communicate, as they will block all tasks.

will help you It's the normal behavior.
If you want to reuse a variable multiple times, a good solution is to use template literals with placeholders.
code :
let name = "Bob"
let template = `Hello ${name}. Your name is ${name}`
// template will contain "Hello Bob. Your name is Bob"
class MyElement extends HTMLElement {
    connectedCallback() {
        var person_name = this.querySelector( '[slot=personName]' ).outerHTML
        this.attachShadow({ mode: "open" })
            .innerHTML = `Hello ${person_name}. Your name is ${person_name}`
    }
}

customElements.define("x-myelement", MyElement)
<x-myelement>
    <span slot="personName">Bob</span>
</x-myelement>
