I am using Intel OneAPI base kit and HPCToolkit to run a simple MPI and DPCPP program. The program can be found here: https://www.intel.com/content/www/us/en/developer/articles/technical/compile-and-run-mpi-programs-using-dpcpp-language.html

The program is compiled as in the website:

$ export I_MPI_CXX=dpcpp
$ mpiicpc -fsycl -std=c++17 -lsycl -ltbb main.cpp -o dpc_reduce

However I get the error as “algorithm “ file not found with include; use “quotes” instead. I tried using quotes but I get the same error. Any help please.

Can you post the exact error message you got? – Mathieu Oct 25 '22 at 09:21
And, if `mpiicpc` works like `gcc`, library should be placed after file to compile, so something like `$ mpiicpc -fsycl -std=c++17 main.cpp -o dpc_reduce -lsycl -ltbb` – Mathieu Oct 25 '22 at 09:23
The question rather suggests an issue with `#include ` – Gilles Gouaillardet Oct 25 '22 at 09:50

This is a C++ question. I've updated the tags for you. – Victor Eijkhout Oct 25 '22 at 13:14
@Mathieu “algorithm “ file not found with include; use “quotes” instead. This is the error message – BoringSession Oct 25 '22 at 16:23
We can run the program successfully on Ubuntu 20.04 and dpcpp 2022.2 version. Could you please provide the Os details,dpcpp version, and error log to reproduce your issue? – HemanthCH Nov 03 '22 at 07:11
