Hajj Pilgrimage Safety Challenges Crowd Simulator Technology

agent elevator writes: In 2010, Saudi Arabia hosted an international design competition aimed at safely accommodating more pilgrims at Mecca's Grand Mosque. One of the participants told IEEE Spectrum that the crowd densities there (6 people per square meter) bogged down off-the-shelf software so badly that simulation run times were about 10 to 20 times slower than real time crowd movement. Nevertheless, he found some workarounds that gave designers a plan to double the Grand Mosque's peak visitor rate from 40,000 to 102,000 people per hour. Last week's stampede took place well away from the mosque, but signals sent to pilgrims telling them when to speed up or slow down could help prevent such a tragedy, the crowd simulation expert said. Other engineers are turning to fuzzy logic as way to predict how crowds will react in a panic.

    Fuck you muzzie scum. Islam = Satan. Tales from the Koran How The Profit Muhammad met his end.

    We shove Jimmy Dean Homestyle Pork Sausage up The Profit Muhammad's ass. Then while the Giver strokes me off I shoot my wad in The Profit Muhammad's face after which we force The Profit Muhammad to fellate an 800 pound Chester White. Simultaneously two Hasidic rabbis open their kosher bowels unleashing torrents of gefilte shit on The Profit Muhammad's head and back while The Giver pumps The Profit Muhammad from behind. After the hog shoots its wad in The Profit Muhammad's mouth The Giver shoots his load up The Profit Muhammad's rectum. Then unexpectedly the Chester White roots out The Profit Muhammad's penis and testicles hungrily biting them off gobbling them down with full porcine fury. We bury the newly castrated The Profit Muhammad up to his nose in pig manure. Two AIDS infected Bowery whores stuff their used condoms and clotted tampon down The Profit Muhammad's throat and crack a bottle of Mad Dog 20/20 over his skull.

    We then leave him for the hogs to munch on. The Profit Muhammad is swine feed and by tomorrow he will be swine manure.

    GOAT KORAN

    For it is written in Mine book that goats are PLEASING and HOLY in Mine eyes. I have told the Prophet Muhammad peace on him! that he should try a goat but he is an ass-infidel and pursues young Muslims. For this is pleasing in Mine eyes as well! I hereby issue a Fatwah: May the asses of the infidels be reamed by the Prophet peace on him! until they look like the goatse.cx man who is of the devil.

      Well, if you have 6 Muslims per square meter surely one of them will suicide bomb the others and help clear the area. /troll

    Basically - and hear me out here - a bunch of Muslims are trampling each other to death in order to pay homage to their magical sky-god.

    Here in the US, we have the good sense to trample other countries to death in order to pay homage to our magical sky-god.

    Only a few muslims will be killed, not all of them.
