Programming parallel for C++ and Python application

I am looking to have a C++ and Python application developed using the processing power of at least one GPU.
We are already using Boost, so Boost.MPI comes to mind.
We already have some experience in developing C++ applications for multi-core CPUs by using threading.
However, since we have not developed sufficient expertise in MPI, we were wondering if a Python solution would be more appropriate, because it will give the developers a better understanding of what the code does. In such a case something like mpi4py would come to mind.

Of course having a GPU specifically for simulation purposes could mean that something like PyOpenCL may be even better.
I mention "simulation", because the machine will be calculating variations on what is largely the same problem, ie not be a general purpose machine.

So in summary:
1- For raw processing speed with a multi-core CPU and a GPU, would a openCL solution or Boost.MPI solution be recommended?
2- Should the Python solution be used only for high level functionality, such as handling data upon return, or does Python compromise speed too much?

     url -- Realtek RTL8150L USB Ethernet driver

SYNOPSIS

     url*    at uhub?
     urlphy* at mii?

DESCRIPTION

     The url driver provides support for USB Ethernet adapters based on the Realtek RTL8150L USB-ether bridge chip.

     The url driver supports the following adapters:

	   CompUSA USBKR100
	   GreenHouse GH-USB100B
	   Melco Inc. LUA-KTX
	   Sitecom LN013

     For more information on configuring this device, see ifconfig(8).

DIAGNOSTICS

     url%d: watchdog timeout  A packet was queued for transmission and a transmit command was issued, however the device failed to acknowledge the
     transmission before a timeout expired.

     url%d: no memory for rx list  The driver failed to allocate an mbuf for the receiver ring.

SEE ALSO
