What’s dgemm.exe? Is it safe or a virus?

dgemm.exe is likely an executable associated with Intel's Math Kernel Library (MKL), specifically implementing the DGEMM routine. DGEMM (Double-precision General Matrix Multiply) is a function used to perform matrix multiplication on double-precision matrices, a fundamental operation in various scientific and engineering applications.

In certain contexts, such as Intel's Processor Diagnostic Tool, dgemm.exe may be utilized to assess the performance and stability of a system's floating-point units by executing intensive matrix multiplication tasks.

If you observe dgemm.exe running on your system without initiating it, it's advisable to check for any Intel diagnostic or benchmarking tools installed that might be invoking this executable.

What does it mean if someone is the publisher of a PC .exe (executable or process)?

The publisher of an executable is the entity responsible for its distribution and authenticity. Most processes/executables on your PC should be signed. The signature on the executable should have been verified through a third party whose job it is to make sure the entity is who it says it is. Find an unsigned executable? You should consider scanning any completely unsigned .exe on your PC.
