If I understood you you correctly, you are going to let Taxi-data (recorded costs) have some impact on an already calculated graph with fixed costs und to somehow influence the route while (or before?) calculating? Is your data already assigned to OSM-Ids (Ways?) or, as you have already mentioned, should rather be assigned to segments (partial ways between ...
As already commented: If you need to estimate better speeds for every road from your taxi tracks that is completely doable with GraphHopper and this open source map matching component for it.
Sounds like you are trying to implement what is known as Floating Car Data (FCD) analysis. This field has received a lot of interest from researchers since the analysis is far from trivial in most cases. There are multiple problems you have to solve, including but not limited to map-matching and routing. Depending on the temporal resolution of your taxi ...
In order to show isochrones on you system you can use the map api service iso4app. Currently is available for 3 countries: Great Britain, Portugal and Italy. More information at www.iso4app.net
I realized I had omitted another good link for you. There is an interesting blog by one of the ESRI developers involved in the HPC stuff (Mansour Raad). I hadn't visited it for a while, but it turns out he actually wrote an article about invoking a Spark job from within ArcGIS for Desktop using ArcGIS Geoprocessing tools. There is code samples as well. I ...
There are a couple of things coming to my mind here: First, and foremost, why you feel the need to use an unproven HPC routing solution to do something for which the OSM community already developed proven and tested solutions? Routing on OSM data has been implemented as several Open Source projects (See http://wiki.openstreetmap.org/wiki/Routing. Even ESRI ...
