UPMEM Processing-In-Memory solution consist of a pool of programmable co-processors, the DPUs, integrated in the memory.

Content

Examples of DPU programs generated with UPMEM DPU SDK

Requirements

• The UPMEM DPU SDK, version 2017.1.1-EAP or later
• Gnu make and gcc, to build the application

#Building the programs

make [TARGET_TYPE=...] to buid the programs for a given target.

• If not set, TARGET_TYPE is by default the functional simulator
• Otherwise, you may select a specific type, such as FPGA

make clean removes the resulting builds.

Executing

The simplest way to execute the programs is to run make test. Otherwise, you may run individual tests manually:

• cd TEST_DIR
• bin/host/program

Where TEST_DIR is the test name (e.g. checksum).

List of demo programs

checksum

The host application generates a random file of 8MB, and schedules multiple DPUs co-processors to compute the checksum on this file. As sanity check it compares host result with the DPU results, and prints out the DPU performances:

• 1. Total number of DPU cycles executed
• 2. The number of DPU cycles per byte processed
