Hi Gerardo, 

 

Thanks for letting us know about the issue you’re seeing. 

 

This was because of a recent change where we added some code for de-registration of buffers. However, for the UCX layer, since CMK_ONESIDED_IMPL (support for the Zerocopy API) is disabled for now, we should’ve also disabled CMK_REG_REQUIRED. 

 

I’ve added a PR (https://github.com/UIUC-PPL/charm/pull/2395) to fix this issue. It should be merged by today after another internal review.

Let us know if you see any other issues. 

 

Thanks,

Nitin

Hello.

 

While building the development version of Charm++ on an IB-enabled cluster of Intel BDW processors, I ran into the following errors in ckrdma.C (possibly due to a missing #include):

 

../bin/charmc   -I.   -c -o ckrdma.o ckrdma.C

ckrdma.C(107): error: identifier "deregisterBuffer" is undefined

        deregisterBuffer(source);

        ^

 

ckrdma.C(116): error: identifier "deregisterBuffer" is undefined

        deregisterBuffer(*this);

        ^

 

ckrdma.C(252): error: identifier "deregisterBuffer" is undefined

        deregisterBuffer(destination);

        ^

 

ckrdma.C(261): error: identifier "deregisterBuffer" is undefined

        deregisterBuffer(*this);

        ^

 

ckrdma.C(366): error: identifier "deregisterDestBuffer" is undefined

        deregisterDestBuffer(info);

        ^

 

ckrdma.C(377): error: identifier "CmiInvokeRemoteDeregAckHandler" is undefined

        CmiInvokeRemoteDeregAckHandler(info->srcPe, info);

        ^

        deregisterSrcBuffer(info);

        ^

 

ckrdma.C(397): error: identifier "CmiInvokeRemoteDeregAckHandler" is undefined

        CmiInvokeRemoteDeregAckHandler(info->destPe, info);

        ^

 

compilation aborted for ckrdma.C (code 2)

Fatal Error by charmc in directory /global/home/users/gerardo/tools/charm/ucx-linux-x86_64-ifort-icc/tmp

charmc exiting...

gmake: *** [ckrdma.o] Error 1

-------------------------------------------------

 

The command line I used for my build was the following:

 

./build ChaNGa ucx-linux-x86_64 icc ifort 2>&1 | tee build_chng_ucx_i185h240.log

 

I’m using Intel 2018.5.274 compilers and HPC-X 2.4.0 (or, more specifically, UCX 1.6.0).

 

Any help or suggestion will be most appreciated.

 

Saludos,

 

Gerardo
