ん.
早速，
scrun -nodes=4,scoredtrace=100 ./a.out
をおこなってみました． プログラムは example/mttl/hello.cc
です．すると，何も反応がない場合と次の3通りの応答がある
場合がありました．

また，
scrun -nodes=4,scoredtrace ./a.out
とすると，
<1> SCore-D:TRACE(../tss.cc:834) TSS scheduler ... idling
<1> SCore-D:TRACE(../tss.cc:834) TSS scheduler ... idling
<1> SCore-D:TRACE(../tss.cc:834) TSS scheduler ... idling
<1> SCore-D:TRACE(../tss.cc:834) TSS scheduler ... idling
<1> SCore-D:TRACE(../tss.cc:834) TSS scheduler ... idling
という出力が続けて出てくることがあります．
診断よろしくお願いします．
