Matrix mulltiplication app compilation fails #174

Closed nitish2112 closed 5 years ago

nitish2112 commented 5 years ago

Hi,

I want to compile Matrix Multiplication on Arria 10 FPGA. I downloaded this repo and spatial-apps (https://github.com/stanford-ppl/spatial-apps/tree/ff8f3026619f323ac0b3799cb429e14bd10b990b). I compiled this repo using:

% make install

After this when I ran matrix multiplication example:

% ./bin/spatial  ../spatial-apps/src/MayMults.scala

It gave me following error:

Am I doing something wrong?

As the error says, the JVM has run out of memory while compiling Spatial. Since the Scala compiler is pretty memory intensive, we recommend using at least the following when compiling the Spatial compiler from source: export SBT_OPTS="-Xmx4G -Xss1G -Xms2G"
